Abstract

Overhead cable transport installation, namely a gondola lift with gondolas (24) coupled in line to two parallel continuous motion suspension/haulage cables (10, 12), by means of a suspension bar (46) hanging in the vertical plane equidistant of the two cables and articulated on a carriage (48) fitted with at least one pair of detachable grips (50-56) intended to connect the carriage (48) to the two cables in line and to disconnect the gondola (24) inside the terminals by detachment of the grips (50-56), so as to allow for embarkation and desembarkation of the passengers at null or reduced speed, characterized by the fact that every grip (50-56) has a body (63) that rests on the upper face of the cable (10, 12) in closed position of the grip and protrudes slightly upwards, and a pair of jaws (60, 62) protruding downwards from said body (63) and opening in downwards direction to clamp the sides of the cable, the end of the jaws coming level with, or protruding slightly lower than the lower face of the cable, in order to facilitate passing over or under the cable support rollers (42), and that inside the terminals (14, 15) guide rollers (92) deviate said cables so as to modify their clearance to each other and so to allow for passage of the carriage (48) disconnected from the cables from a position above the cable towards a lower position, or inversely.

Description

L'invention est relative à une installation de transport à câble aérien, notamment une télécabine ayant des véhicules accouplés en ligne à deux câbles parallèles porteurs-tracteurs à défilement continu par une suspente s'étendant dans le plan vertical de symétrie des câbles et articulée à un chariot portant au moins une paire de pinces débrayables pour solidariser le chariot aux deux câbles en ligne et pour désaccoupler le véhicule dans les stations par débrayage des pinces pour un embarquement et/ou débarquement à vitesse réduite ou nulle des passagers.The invention relates to an overhead cable transport installation, in particular a gondola lift having vehicles coupled in line to two parallel carrier-tractor cables with continuous travel by a hanger extending in the vertical plane of symmetry of the cables and articulated at a carriage carrying at least one pair of disengageable clamps for securing the carriage to the two cables in line and for uncoupling the vehicle in stations by disengaging the clamps for boarding and / or disembarking at reduced or zero speed of passengers.

Une télécabine du genre mentionné présente de multiples avantages, notamment de simplicité, de débit important et de facilité d'embarquement et de débarquement des passagers.A gondola of the kind mentioned has many advantages, in particular simplicity, high throughput and ease of embarkation and disembarkation of passengers.

La suspension est disposée dans le plan vertical de symétrie des deux câbles et l'appui sur deux câbles confère une grande stabilité latérale, les efforts latéraux exercés sur les véhicules, notamment par le vent, étant transmis aux câbles.The suspension is arranged in the vertical plane of symmetry of the two cables and the support on two cables gives great lateral stability, the lateral forces exerted on the vehicles, in particular by the wind, being transmitted to the cables.

Une télécabine connue (FR-A-1.249.949) comporte des pinces agrippant le câble par le dessous, les mors de la pince assurant la double fonction de support du poids de la cabine et d'immobilisation de cette dernière sur le câble.A known gondola (FR-A-1,249,949) comprises clamps gripping the cable from below, the jaws of the clamp ensuring the double function of supporting the weight of the cabin and immobilizing the latter on the cable.

La fiabilité de telles pinces n'est pas absolue, car le poids tend à ouvrir les mors de la pince. L'encombrement de la pince, notamment la saillie en-dessous et au-dessus du câble, empêche le passage des pinces sur les galets de support et sous des galets de compression et il est nécessaire de prévoir des guides écartant le câble des galets au passage de la pince, ce qui est pratiquement irréalisable dans les installations importantes à câble sous forte tension.The reliability of such pliers is not absolute, because the weight tends to open the jaws of the pliers. The size of the clamp, in particular the projection below and above the cable, prevents the passage of the clamps on the support rollers and under compression rollers and it is necessary to provide guides separating the cable from the rollers at passage of the clamp, which is practically impracticable in large installations with high voltage cable.

La présente invention a pour but de remédier à ces inconvénients et de permettre la réalisation d'une installation à deux câbles porteurs-tracteurs conservant les avantages de simplicité des télécabines monocâble.The object of the present invention is to remedy these drawbacks nients and allow the realization of an installation with two carrying cables-tractors retaining the advantages of simplicity of single cable gondolas.

L'installation selon l'invention est caractérisée en ce que chaque pince comporte un corps de pince prenant appui en position embrayée de la pince sur la face supérieure du câble et présentant une faible saillie vers le haut et une paire de mors faisant saillie dudit corps en étant ouverts vers le bas pour enserrer latéralement le câble, l'extrémité des mors affleurant ou dépassant faiblement la face inférieure du câble pour faciliter le passage sur et sous les galets de support des câbles, et que dans les stations des galets de guidage dévient lesdits câbles pour modifier leur écartement et permettre un dégagement du chariot désaccouplé des câbles.The installation according to the invention is characterized in that each clamp comprises a clamp body bearing in the engaged position of the clamp on the upper face of the cable and having a slight upward projection and a pair of jaws projecting from said body by being open downwards to grip the cable laterally, the end of the jaws flush or slightly protruding from the underside of the cable to facilitate passage over and under the cable support rollers, and that in the guide roller stations deflects said cables to modify their spacing and allow disengagement of the uncoupled cable carriage.

En conservant les pinces conventionnelles en appui sur la face supérieure des câbles, le problème du passage des galets et la sécurité de fonctionnement sont résolus, mais après ouverture des pinces dans les stations le chariot reste emprisonné entre les câbles. Selon l'invention, des galets de guidage des câbles modifient l'écartement de ces derniers pour permettre le dégagement du chariot et la circulation du chariot sur des rails de transfert indépendants de la trajectoire des câbles.By keeping the conventional clamps resting on the upper face of the cables, the problem of the passage of the rollers and the operational safety are resolved, but after opening the clamps in the stations the carriage remains trapped between the cables. According to the invention, cable guide rollers modify the spacing of the latter to allow the carriage to be released and the carriage to circulate on transfer rails independent of the path of the cables.

L'écart entre les câbles résulte d'un compromis entre la nécessité de maintenir les dimensions des structures de support dans des limites acceptables et maitrisables et d'autre part de disposer entre les câbles d'un espace suffisant au logement des galets horizontaux de guidage dans les stations et d'assurer la stabilité latérale. L'écart est avantageusement compris entre 25 et 100cm, de préférence voisin de 75 cm. Le diamètre des câbles est compris dans la fourchette de 0,035 à 0,050 m et de préférence voisin de 0,042 m.The distance between the cables results from a compromise between the need to keep the dimensions of the support structures within acceptable and manageable limits and, on the other hand, to have sufficient space between the cables to accommodate the horizontal guide rollers. in stations and to provide lateral stability. The difference is advantageously between 25 and 100 cm, preferably close to 75 cm. The diameter of the cables is within the range of 0.035 to 0.050 m and preferably close to 0.042 m.

Pour bénéficier totalement de la stabilité latérale conférée par le double appui du chariot, le véhicule est fixé par sa suspension au chariot avec un seul degré de liberté correspondant à une oscillation dans le plan vertical de symétrie.To fully benefit from the lateral stability conferred rée by the double support of the carriage, the vehicle is fixed by its suspension to the carriage with a single degree of freedom corresponding to an oscillation in the vertical plane of symmetry.

Selon un développement de l'invention, le chariot porte deux paires de pinces débrayables, deux pinces pour chaque câble, et ces pinces peuvent être décalées les unes par rapport aux autres dans la direction de déplacement du chariot ou être disposées face à face deux par deux avec une certaine imbrication, par exemple une disposition coaxiale des ressorts. Les deux pinces accouplées à un même câble sont disposées symétriquement de part et d'autre de l'axe transversal de symétrie du chariot passant par les points résultants d'accouplement aux câbles. La commande d'ouverture et de fermeture des pinces à l'entrée et à la sortie des stations peut être commune à l'ensemble des pinces du chariot, mais il est préférable, pour des raisons de sécurité et de standardisation, de prévoir un levier de commande individuel à chaque pince, venant dans la zone de débrayage et/ou d'embrayage au contact d'un rail ou d'une came fixe de la manière usuelle. La commande est alors symétrique par rapport au plan vertical de symétrie des câbles pour ne pas engendrer des efforts de déséquilibre du chariot lors du fonctionnement des leviers. Un autre mode de commande est concevable. Chaque pince est avantageusement montée sur le chariot par l'intermédiaire d'un bloc amortisseur élastique permettant une légère rotation d'une pince par rapport à l'autre sur un môme câble et des pinces de l'un des câbles par rapport à celles de l'autre câble pour éviter tout gauchissement du chariot.According to a development of the invention, the carriage carries two pairs of disengageable clamps, two clamps for each cable, and these clamps can be offset with respect to each other in the direction of movement of the carriage or be arranged face to face two by two with a certain overlap, for example a coaxial arrangement of the springs. The two clamps coupled to the same cable are arranged symmetrically on either side of the transverse axis of symmetry of the carriage passing through the resulting points of coupling to the cables. The command to open and close the clamps at the entrance and exit of the stations can be common to all the clamps of the carriage, but it is preferable, for reasons of safety and standardization, to provide a lever individual control to each clamp, coming into the declutching and / or clutch zone in contact with a rail or a fixed cam in the usual manner. The control is then symmetrical with respect to the vertical plane of symmetry of the cables so as not to generate efforts to unbalance the carriage during the operation of the levers. Another control method is conceivable. Each clamp is advantageously mounted on the carriage by means of an elastic damping block allowing a slight rotation of one clamp relative to the other on the same cable and of the clamps of one of the cables relative to those of the other cable to prevent warping of the carriage.

Les quatre pinces constituent un quadrilatère rigide de liaison entre les deux câbles, lesquels se déplacent obligatoirement en synchronisme. Elles présentent la même hauteur de matière symétriquement pour passer sous des trains de galets parallèles sans exercer des efforts dissymétriques tendant à déformer ou à gauchir le chariot.The four clamps constitute a rigid quadrilateral connecting the two cables, which must move in synchronism. They have the same height of material symmetrically to pass under trains of parallel rollers without exerting asymmetrical forces tending to deform or warp the carriage.

De même les systèmes d'entraînement et/ou de freinage des véhicules à l'entrée, à la sortie ou dans les stations sont doubles et symétriques.Likewise the drive and / or braking systems of vehicles at entry, exit or at stations are double and symmetrical.

Selon une caractéristique importante de la présente invention, les deux boucles de câbles présentent une symétrie parfaite de frottement, c'est-à-dire que les résistances à l'entraînement des deux câbles sont identiques, cela étant réalisé par des trajectoires symétriques et/ou des dispositifs régulateurs de freinage de l'un des câbles.According to an important characteristic of the present invention, the two cable loops have a perfect symmetry of friction, that is to say that the resistances to the driving of the two cables are identical, this being achieved by symmetrical paths and / or brake regulating devices on one of the cables.

Dans la station d'entraînement chaque câble passe sur une poulie d'extrémité, les deux poulies étant identiques et superposées. L'entraînement des deux poulies est réalisé par un système différentiel exerçant le même effort de traction sur les deux câbles. Ce différentiel peut être mécanique, hydraulique ou électrique. L'action combinée du différentiel, de l'égalité des frottements et de la liaison entre les deux câbles par les quadrilatères rigides constitués par les pinces des véhicules réalise un entraînement synchrone en évitant toute intégration de décalages et mise en oblique des véhicules. Il est clair que des précautions analogues sont essentielles lors d'un freinage des poulies et selon un autre développement de l'invention, le dispositif de freinage solidarise obligatoirement les deux poulies. Un moyen simple consiste à insérer les jantes des deux poulies coaxiales,. et très proche l'une de l'autre, entre l'étrier du frein, les mâchoires appliquant les jantes l'une contre l'autre lors du serrage. L'emploi d'un étrier unique assure une répartition de la force de freinage sur les deux poulies et en même temps une liaison par friction entre ces deux poulies évitant tout décalage. Une bande de freinage présentant une certaine élasticité peut être rapportée au pourtour externe de chaque poulie.In the drive station each cable passes over an end pulley, the two pulleys being identical and superimposed. The two pulleys are driven by a differential system exerting the same tensile force on the two cables. This differential can be mechanical, hydraulic or electric. The combined action of the differential, the equality of friction and the connection between the two cables by the rigid quadrilaterals constituted by the clamps of the vehicles achieves a synchronous drive by avoiding any integration of offsets and obliquing of the vehicles. It is clear that similar precautions are essential during braking of the pulleys and according to another development of the invention, the braking device necessarily binds the two pulleys. A simple way is to insert the rims of the two coaxial pulleys. and very close to each other, between the brake caliper, the jaws applying the rims against each other when tightening. The use of a single caliper ensures a distribution of the braking force on the two pulleys and at the same time a friction connection between these two pulleys avoiding any offset. A braking band having a certain elasticity can be added to the outer periphery of each pulley.

En ce qui concerne le différentiel, il peut être avantageusement réalisé de façon électrique en travaillant à puissance égale pour les deux moteurs rigoureusement identiques. Si tel est le cas par construction, les efforts à vaincre sont les mêmes pour les deux boucles de câbles, la vitesse de déplacement des câbles sera la même, quelque soit les diamètres comparés des deux poulies d'entraînement, puisque la puissance comparée est le produit de l'effort à vaincre par la vitesse de déplacement.As regards the differential, it can advantageously be produced electrically by working at equal power for the two strictly identical motors. If this is the case by construction, the forces to be overcome are the same for the two cable loops, the speed of movement of the cables will be the same, whatever or the compared diameters of the two drive pulleys, since the compared power is the product of the effort to be overcome by the speed of movement.

Pour réaliser un tel différentiel électrique, il est prévu une source d'alimentation en courant continu commune aux deux moteurs de caractéristiques électriques identiques.To produce such an electrical differential, a DC power source is provided common to the two motors with identical electrical characteristics.

Si les deux boucles de câbles ont des efforts égaux à vaincre en ligne, si les rendements mécaniques des machineries sont égaux et si les moteurs sont identiques, quand on alimentera ces derniers avec une même source de courant continu, les tensions et les intensités de courant seront les mêmes dans les deux circuits d'alimentation des moteurs qui travailleront bien à puissance égale.If the two cable loops have equal forces to overcome in line, if the mechanical yields of the machinery are equal and if the motors are identical, when the latter are supplied with the same direct current source, the voltages and current intensities will be the same in the two motor supply circuits which will work well at equal power.

Si, par contrer un élément extérieur change - et notamment s'il se produit une inégalité d'efforts à vaincre en ligne - les moteurs travailleront de façon dissymétrique, tension et/ou intensité variant.If, by countering an external element changes - and in particular if there is an inequality of efforts to be overcome in line - the motors will work asymmetrically, voltage and / or intensity varying.

Un des intérêts essentiels de ce système de différentiel électrique est donc de signaler - par rapport à l'état initial qui peut donc être légèrement dissymétrique - toute inégalité de fonctionnement d'une boucle par rapport à l'autre.One of the essential interests of this electric differential system is therefore to point out - compared to the initial state which can therefore be slightly asymmetrical - any unequal functioning of one loop compared to the other.

Des cadrans, munis de différents seuils à fonctions de commande, permettent alors à tout moment de connaître l'état d'une boucle par rapport à l'autre et d'arrêter automatiquement l'installation en cas de déréglage dépassant une valeur prédéterminée. Cette signalisation et cette boucle de commande constituent donc un dispositif de sécurité fondamental.Dials, provided with various thresholds with control functions, then make it possible at any time to know the state of a loop with respect to the other and to automatically stop the installation in the event of an adjustment exceeding a predetermined value. This signaling and this control loop therefore constitute a fundamental safety device.

Dans la station de mise sous tension chaque câble passe sur une poulie folle de renvoi, les deux poulies étant montées sur un palonnier de tension équilibrant la tension dans les deux poulies, palonnier mécanique, hydraulique ou électrique. Les poulies de renvoi sont avantageusement décalées latéralement par rapport à la direction des câbles d'une distance correspondant à l'écartement des deux câbles dans la station. L'écartement longitudinal des deux poulies compense de légères inégalités de longueur des deux boucles de câbles.In the tensioning station, each cable passes over a loose return pulley, the two pulleys being mounted on a tension rudder balancing the tension in the two pulleys, mechanical, hydraulic or electric spreader. The return pulleys are advantageously offset laterally with respect to the direction of the cables by a distance corresponding to the spacing of the two cables in the station. The longitudinal spacing of the two pulleys compensates for slight differences in length of the two cable loops.

Dans les stations les chariots sont désaccouplés des câbles et pris en charge par des rails de transfert passant devant les quais de débarquement et d'embarquement. Les chariots ont quatre roues roulant sur les rails, soit par gravité, soit sous l'action d'un dispositif moteur, par exemple une chaîne à taquets. Les roues sont disposées par paire face à face et roulent dans les parties rectilignes sur deux rails parallèles. Dans les courbes subsiste un seul rail, intérieur au virage, ce qui facilite les aiguillages.In the stations, the carriages are uncoupled from the cables and supported by transfer rails passing in front of the landing and embarkation platforms. The carriages have four wheels rolling on the rails, either by gravity, or under the action of a motor device, for example a chain with cleats. The wheels are arranged in pairs face to face and roll in the rectilinear parts on two parallel rails. In the curves, only one rail remains, inside the bend, which facilitates switches.

Selon un mode de mise en oeuvre préféré de l'invention, le chariot est intercalé entre les deux câbles, les pinces faisant saillie latéralement de part et d'autre vers l'extérieur. Après ouverture des pinces et sortie des câbles par un mouvement relatif vers le haut du chariot par rapport aux câbles, ces derniers sont déviés à écartement pour libérer le gabarit de passage des pinces et permettre un dégagement du chariot par le bas. Ce dégagement s'effectue à l'entrée de la station au passage du chariot sur un tronçon de dégagement, un système symétrique à la sortie de la station assurant l'engagement et le réaccouplement du chariot aux câbles.According to a preferred embodiment of the invention, the carriage is interposed between the two cables, the clamps projecting laterally from either side towards the outside. After opening of the clamps and exit of the cables by a relative movement towards the top of the carriage with respect to the cables, the latter are deviated with spacing to release the jig for passage of the clamps and allow the carriage to be disengaged from the bottom. This release takes place at the entrance to the station when the carriage passes over a release section, a symmetrical system at the station exit ensuring the engagement and re-coupling of the carriage to the cables.

La capacité des véhicules, notamment de 12 à 30 passagers, permet de limiter le nombre de véhicules en service et il est avantageux de pouvoir stocker les véhicules ou tout au moins un nombre suffisant de véhicules au service normal sur les rails de transfert, le départ d'un véhicule s'effectuant à la demande.The capacity of the vehicles, in particular from 12 to 30 passengers, makes it possible to limit the number of vehicles in service and it is advantageous to be able to store the vehicles or at least a sufficient number of vehicles in normal service on the transfer rails, departure of a vehicle made on demand.

Chaque câble porteur-tracteur passe au niveau d'un pylône sur un balancier qui peut comporter des galets de support ou des galets de compression. Les deux balanciers identiques sont parfaitement symétriques et leurs axes principaux sont rigoureusement face à face. Les supports en U renversé de ces axes sont par exemple centrés face à face en usine par une même aléseuse. Le support en U renversé laisse le libre passage du chariot entre les balanciers. L'écartement limité des câbles, notamment de 75 cm, permet de conserver une rigidité suffisante avec des structures usuelles. Pour conserver la parfaite symétrie des deux balanciers, les éléments de ces derniers sont reliés entre eux par des U renversés disposés à l'entrée de chaque élément, l'entrée étant définie par rapport au sens de défilement des câbles.Each carrier-tractor cable passes at the level of a pylon on a pendulum which may include support rollers or compression rollers. The two identical pendulums are perfectly symmetrical and their main axes are rigorously face to face. The inverted U supports of these axes are for example centered face to face in the factory by the same boring machine. The inverted U-shaped support allows the carriage to pass freely between the pendulums. The limited spacing of the cables, in particular 75 cm, makes it possible to maintain sufficient rigidity with conventional structures. To maintain the perfect symmetry of the two pendulums, the elements of the latter are connected together by inverted U's arranged at the entrance to each element, the entrance being defined relative to the direction of travel of the cables.

La disposition inventive sans balancement latéral au passage des pylônes, autorise l'emploi de galets de support dont les flasques intérieurs à la voie sont d'un diamètre agrandi pour réaliser un dispositif anti-dérailleur très efficace.The inventive arrangement without lateral swinging of the passage of the pylons, allows the use of support rollers whose flanges inside the track are of an enlarged diameter to produce a very effective anti-derailleur device.

Selon une variante de réalisation, les pinces sont orientées vers l'intérieur, le chariot en forme de U encadrant les deux câbles. L'encombrement du chariot est accru, mais les potences de support des balanciers sont simplifiées et se limitent à une simple traverse portant à chacune de ses extrémités un balancier. Le dégagement du chariot nécessite un pinçage des deux câbles.According to an alternative embodiment, the clamps are oriented inward, the U-shaped carriage framing the two cables. The size of the carriage is increased, but the support brackets of the pendulums are simplified and are limited to a simple cross member carrying at each of its ends a pendulum. Disengaging the carriage requires pinching the two cables.

Sur les figures, deux câbles porteurs-tracteurs 10, 12 d'une télécabine s'étendent en circuit fermé entre deux stations 14, 15 en passant dans les stations sur des poulies 16, 17; 18, 19 d'extrémités à axe vertical 20, 21; 22, 23. Les poulies d'extrémités 16, 17 de la station 14 sont des poulies motrices entraînant les câbles 10, 12 en continu à une môme vitesse. Les véhicules 24 sont accouplés aux câbles 10, 12 en ligne, plusieurs véhicules 24 pouvant se succéder ou être échelonnés le long des câbles 10, 12. A l'entrée d'une station 14, 15, les véhicules 24 sont désaccouplés des câbles 10, 12 et pris en charge par des rails de transfert 26 passant devant des quais de débarquement et d'embarquement. Les passagers montent et descendent des véhicules 24 à l'arrêt ou circulant à faible vitesse et à la sortie de la station les véhicules 24 sont accélérés par tout moyen approprié avant d'être réancouplés aux câbles 10, 12 sur la voie opposée. Ce fonctionnement des télécabines est bien connu des spécialistes.In the figures, two carrier cables 10, 12 of a gondola extend in a closed circuit between two stations 14, 15 passing through the stations on pulleys 16, 17; 18, 19 of vertical axis ends 20, 21; 22, 23. The end pulleys 16, 17 of the station 14 are drive pulleys driving the cables 10, 12 continuously at the same speed. The vehicles 24 are coupled to the cables 10, 12 in line, several vehicles 24 being able to follow one another or be staggered along the cables 10, 12. At the entrance to a station 14, 15, the vehicles 24 are uncoupled from the cables 10 , 12 and supported by rails transfer 26 passing in front of landing and loading docks. The passengers get on and off the vehicles 24 at a standstill or traveling at low speed and at the exit from the station the vehicles 24 are accelerated by any appropriate means before being re-coupled to the cables 10, 12 on the opposite lane. This operation of cable cars is well known to specialists.

Les câbles 10, 12 porteurs-tracteurs sont parallèles et à un même niveau en ligne, leur écartement constant étant compris dans la fourchette de 0,25 à 1,00m, de préférence voisin de 75 cm. Chaque câble 10, 12 a un diamètre compris dans la fourchette de 0,035 à 0,050 m, de préférence voisin de 0,042 m. Les câbles 10, 12 sont supportés par des pylônes 28 de support et de maintien de structure identique, seul un pylône de support étant décrit ci-dessous en référence aux figures 1 et 2. A chacune des extrémités d'une travée ou potence 30 est suspendu un étrier 32 en U renversé respectivement de support des câbles 10, 12 de la voie montante et de la voie descendante. A l'extrémité de chaque branche de l'étrier 32 est fixé un axe 38, 40 d'articulation d'un balancier 34, 36 portant les galets 42 de support des câbles 10, 12. L'écartement des balanciers 34, 36 correspond à celui des câbles 10, 12 et l'ensemble étrier 32, balanciers 34, 36 est symétrique par rapport au plan vertical de symétrie des câbles 10, 12 de trace X-X sur la fig. 1. Les axes 38, 40 sont parfaitement alignés, leurs supports ayant été centrés face à face en usine sur une même aléseuse. Les balanciers 34, 36 se débattent dans des plans verticaux parallèles et comportent un nombre de balanciers secondaires approprié à la charge. Pour conserver la parfaite symétrie des balanciers 34, 36 il est avantageux de relier les axes secondaires, voire tertiaires, par des étriers 44 en U renversé imposant un pivotement symétrique. Sur les figures 11 à 13, seuls les derniers éléments des balanciers 34, 36 sont reliés entre eux par des étriers 44, disposés à l'entrée, par rapport au sens de défilement du câble 10, 12 de l'élément. Les câbles 10, 12 passent sur les galets 42 des balanciers de support 34,36, de la manière usuelle et il est facile de voir que l'intervalle entre les câbles 10, 12 est entièrement dégagé pour le passage des véhicules 24. Les câbles 10, 12 passent évidemment sous les galets d'un balancier de maintien (non représenté). Les flasques, intérieurs par rapport à la voie, des galets 42 sont agrandis pour bien encadrer les câbles 10, 12 et empêcher tout déraillement.The cables 10, 12 tractor-carriers are parallel and at the same level in line, their constant spacing being within the range of 0.25 to 1.00 m, preferably close to 75 cm. Each cable 10, 12 has a diameter in the range of 0.035 to 0.050 m, preferably close to 0.042 m. The cables 10, 12 are supported by support and support pylons of identical structure, only a support pylon being described below with reference to Figures 1 and 2. At each end of a span or bracket 30 is suspended a bracket U-shaped upturned respectively to support the cables 10, 12 of the uplink and the downlink. At the end of each branch of the stirrup 32 is fixed an axis 38, 40 of articulation of a pendulum 34, 36 carrying the rollers 42 for supporting the cables 10, 12. The spacing of the pendulums 34, 36 corresponds to that of the cables 10, 12 and the caliper assembly 32, pendulums 34, 36 is symmetrical relative to the vertical plane of symmetry of the cables 10, 12 of trace XX in FIG. 1. The axes 38, 40 are perfectly aligned, their supports having been centered face to face in the factory on the same boring machine. The pendulums 34, 36 struggle in parallel vertical planes and include a number of secondary pendulums suitable for the load. To preserve the perfect symmetry of the pendulums 34, 36 it is advantageous to connect the secondary axes, even tertiary, by stirrups 44 in inverted U imposing a symmetrical pivoting. In FIGS. 11 to 13, only the last elements of the pendulums 34, 36 are interconnected by stirrups 44, arranged at the entrance, relative to the direction of travel of the cable 10, 12 of the element. Cables 10, 12 pass on the rollers 42 of the support beams 34, 36, in the usual manner and it is easy to see that the interval between the cables 10, 12 is entirely cleared for the passage of vehicles 24. The cables 10, 12 obviously pass under the rollers of a holding balance (not shown). The flanges, interior with respect to the track, of the rollers 42 are enlarged to properly frame the cables 10, 12 and prevent any derailment.

Chaque véhicule 24 comprend une suspension 46 articulée à sa partie supérieure à un axe transversal 58 d'un chariot 48 portant quatre pinces 50, 52, 54, 56 d'accouplement aux câbles 10, 12. La largeur du corps du chariot 48 est légèrement jnféricurc à l'écartement entre les câbles 10, 12 tandis que les mors 60, 62 des pinces 50 à 56 font saillie des deux côtés latéraux du chariot pour enserrer les câbles 10, 12. Les figures 5 et 6 représentent schématiquement une pince prenant appui sur le câble et ayant un mors mobile 62 disposé respectivement à l'intérieur et à l'extérieur. Les mors 60; 62 sont sollicités en position de fermeture par un ressort 64 et chaque pince 50 à 56 comporte un levier de commande 66 coopérant dans les stations avec une came ou un rail s'étendant le long de la trajectoire du chariot 48 pour commander l'ouverture et la fermeture de la pince. Les pinces peuvent être d'un type différent, notamment de ceux décrits ci-dessous.Each vehicle 24 comprises a suspension 46 articulated at its upper part to a transverse axis 58 of a carriage 48 carrying four clamps 50, 52, 54, 56 for coupling to the cables 10, 12. The width of the body of the carriage 48 is slightly jnféricurc at the spacing between the cables 10, 12 while the jaws 60, 62 of the clamps 50 to 56 protrude from the two lateral sides of the carriage to grip the cables 10, 12. Figures 5 and 6 schematically show a clamp bearing on the cable and having a movable jaw 62 disposed respectively inside and outside. The jaws 60 ; 62 are biased in the closed position by a spring 64 and each clamp 50 to 56 comprises a control lever 66 cooperating in the stations with a cam or a rail extending along the trajectory of the carriage 48 to control the opening and closing the clamp. The clamps can be of a different type, in particular from those described below.

Les pinces 50 à 56 peuvent être décalées dans la direction longitudinale du chariot pour des raisons d'encombrement, mais il est clair que des pinces d'une structure différente peuvent être utilisées et que les pinces 50, 54; 52, 56 se faisant face peuvent être alignées et imbriquées. Les ressorts peuvent être coaxiaux et certains éléments, notamment le levier de commande 66, peuvent être communs à plusieurs pinces. Les leviers de commande 66 sont disposés face à face pour que les forces de manoeuvre s'équilibrent et n'exercent aucune réaction transversale sur le chariot 48.The clamps 50 to 56 can be offset in the longitudinal direction of the carriage for reasons of space, but it is clear that clamps of a different structure can be used and that the clamps 50, 54; 52, 56 facing each other can be aligned and nested. The springs can be coaxial and certain elements, in particular the control lever 66, can be common to several clamps. The control levers 66 are arranged face to face so that the operating forces are balanced and exert no transverse reaction on the carriage 48.

Les mors 60, 62 sont conformés pour passer sur et sous les galets 42 sans à-coup notable et la hauteur de saillie du chariot 48 au-dessus des câbles 10, 12 est réduite au maximum pour faciliter le dégagement. De plus, en tout plan perpendiculaire à la ligne, cette hauteur de saillie est égale d'un câble à l'autre, de façon à éviter toute torsion au chariot lors du passage sous les balanciers compression. Le chariot 48 porte quatre roues 68 pour le déplacement sur les rails 26 des stations 14, les roues 68 étant disposées face à face. Des blocs (non représentés) élastiques de fixation des pinces 50-56 autorisent un léger pivotement.The jaws 60, 62 are shaped to pass over and under the rollers 42 without a noticeable jerk and the height of projection of the carriage 48 above the cables 10, 12 is reduced to the maximum to facilitate the release. In addition, in any plane perpendicular to the line, this projection height is equal from one cable to the other, so as to avoid any twisting of the carriage when passing under the compression pendulums. The carriage 48 carries four wheels 68 for moving on the rails 26 of the stations 14, the wheels 68 being arranged face to face. Elastic blocks (not shown) for fixing the clamps 50-56 allow a slight pivoting.

Un autre mode de réalisation du chariot 48 est illustré par les figures 7 à 10, les quatre pinces 50, 52, 54, 56 étant du type décrit dans la demande de brevet français N° 81 00432 du 9 Janvier 1981. Le mors mobile 62 est porté par le levier de commande 66; articulé sur un corps de pince 63 prenant appui sur le câble. Le levier 66 porte à l'extrémité opposée un galet de commande. Le ressort 64 attaque ladite extrémité opposée pour solliciter la pince en position de serrage du câble 10. Les pinces 54, 56, associées au câble 12 sont disposées symétriquement de part et d'autre de l'axe transversal Y-Y du chariot 48 tandis que les pinces 50, 52, également symétriques, encadrent les pinces 54, 56. Les points fictifs d'accouplement des pinces 54, 56; 50, 52 aux câbles 10, 12 sont ainsi situés sur l'axe Y-Y, évitant une dissymétrie d'entraînement du chariot 48. Le fonctionnement des pinces est évident et le lecteur peut se référer à la demande de brevet précitée pour de plus amples détails. Dans les stations, les roues 68 roulent sur deux rails parallèles 26, l'un des rails étant avantageusement supprimé dans les courbes, ce qui. facilite les aiguillages. Le chariot 48 porte deux plaques de friction 70 susceptibles de coopérer avec des roues d'entraînement 72 dans les stations (fig. 20). Cet entraînement est parfaitement symétrique.Another embodiment of the carriage 48 is illustrated in FIGS. 7 to 10, the four clamps 50, 52, 54, 56 being of the type described in French patent application No. 81 00432 of January 9, 1981. The movable jaw 62 is carried by the control lever 66; articulated on a clamp body 63 bearing on the cable. The lever 66 carries at the opposite end a control roller. The spring 64 attacks said opposite end to urge the clamp in the cable clamping position 10. The clamps 54, 56, associated with the cable 12 are arranged symmetrically on either side of the transverse axis YY of the carriage 48 while the clamps 50, 52, also symmetrical, frame the clamps 54, 56. The fictitious coupling points of the clamps 54, 56; 50, 52 to the cables 10, 12 are thus located on the YY axis, avoiding an asymmetry in driving the carriage 48. The operation of the clamps is obvious and the reader can refer to the aforementioned patent application for more details . In stations, the wheels 68 roll on two parallel rails 26, one of the rails being advantageously removed in the curves, which. facilitates referrals. The carriage 48 carries two friction plates 70 capable of cooperating with drive wheels 72 in the stations (fig. 20). This training is perfectly symmetrical.

La suspension 46. est droite dans le plan de symétrie des câbles 10, 12 et le seul-mouvement autorisé, relatif au chariot 48, est un pivotement sur l'axe 58 se traduisant par un débattement dans ledit plan de symétrie. On comprend que la suspension 46 est toujours perpendiculaire à l'axe 58, c'est-à-dire à la ligne de niveau des deux câbles 10, 12. Comme les câbles 10, 12 sont obligatoirement au même niveau au droit des balanciers 34, 36 la suspension 46: est verticale et la stabilité des véhicules 24 au passage des pyl8nes est remarquable. Le couple de rappel exercé sur la cabine 24 à l'entrée des balanciers 34, 36 est proportionnel à l'écartement des câbles 10, 12 et on a intérêt à écarter les câbles 10, 12 au maximum. Un grand écart permet d'autre part le logement du chariot 48 entre les câbles 10, 12 et la déviation des câbles 10, 12 dans les stations 14 par des galets à axe vertical de la manière décrite ci-dessous. Inversement, les structures de support, notamment les étriers 32, 44, deviennent rapidement trop importantes et une distance d'écartement de 75 cm est un compromis valable. La suspension à deux câbles 10, 12 de forte section assure une sécurité accrue et les véhicules 24 peuvent être relativement grands, par exemple pour le transport de plusieurs dizaines de passagers.The suspension 46. is straight in the plane of symmetry of the cables 10, 12 and the only authorized movement, relative to the carriage 48, is a pivoting on the axis 58 resulting in by a movement in said plane of symmetry. It is understood that the suspension 46 is always perpendicular to the axis 58, that is to say to the level line of the two cables 10, 12. Like the cables 10, 12 are necessarily at the same level in line with the pendulums 34 , 36 the suspension 46: is vertical and the stability of the vehicles 24 when the towers pass is remarkable. The return torque exerted on the cabin 24 at the entry of the pendulums 34, 36 is proportional to the spacing of the cables 10, 12 and it is advantageous to separate the cables 10, 12 as much as possible. A large gap also allows the housing of the carriage 48 between the cables 10, 12 and the deflection of the cables 10, 12 in the stations 14 by rollers with a vertical axis as described below. Conversely, the support structures, in particular the stirrups 32, 44, quickly become too large and a spacing distance of 75 cm is a valid compromise. The suspension with two cables 10, 12 of large section provides increased security and the vehicles 24 can be relatively large, for example for transporting several tens of passengers.

Les câbles 10, 12 forment deux boucles sans fin s'étendant entre les stations d'entraînement 14 et de mise sous tension 15. Les poulies d'entraînement 16, 17 de la station 14 sont superposées et coaxiales, l'écartement entre les deux poulies 16., 17 étant très faible. Les poulies d'entraînement 16, 17 sont avantageusement munies chacune d'une piste de freinage 71, 73 prolongeant le flasque intérieur de la poulie et d'inertie moindre que la poulie. Un étrier de freinage 74 enserre les deux pistes 71, 73 de manière que l'un 76 des patins de freinage engage la face libre de l'une des pistes et l'autre 78 des. patins engage la face libre de l'autre piste. Le frein est par exemple du type hydraulique imposant un rapprochement des patins 76, 78 qui sont appliqués sur les pistes 71, 73 avec une même force, l'étrier 74 étant monté flottant. Lors d'un freinage les pistes 71, 73 sont appliquées l'une sur l'autre, de façon à solidariser les poulies 16, 17.The cables 10, 12 form two endless loops extending between the drive 14 and tensioning stations 15. The drive pulleys 16, 17 of the station 14 are superimposed and coaxial, the spacing between the two pulleys 16., 17 being very weak. The drive pulleys 16, 17 are advantageously each provided with a braking track 71, 73 extending the inner flange of the pulley and of less inertia than the pulley. A brake caliper 74 encloses the two tracks 71, 73 so that one 76 of the brake pads engages the free face of one of the tracks and the other 78 of. skates engage the free face of the other track. The brake is for example of the hydraulic type imposing a bringing together of the pads 76, 78 which are applied to the tracks 71, 73 with the same force, the caliper 74 being mounted floating. During braking, the tracks 71, 73 are applied to one another, so as to secure the pulleys 16, 17.

Les axes 20, 21 des poulies 16, 17 sont reliés par des transmissions 80, 82 aux planétaires 84, 86 d'un mécanisme différentiel 88 dont les pignons 90 sont entraînés par un moteur 92. Ce mécanisme différentiel peut être hydraulique ou électrique, le résultat étant un entraînement à force égale des deux câbles 10, 12 et un rééquilibrage permanent de ces forces.The axes 20, 21 of the pulleys 16, 17 are connected by transmissions 80, 82 to the planet gears 84, 86 of a differential mechanism 88 whose pinions 90 are driven by a motor 92. This differential mechanism can be hydraulic or electric, the result being an equal force drive of the two cables 10, 12 and a permanent rebalancing of these forces.

En se référant plus particulièrement à la fig. 15, on voit que les câbles 10,12 passent sur des galets de guidage 92 à l'entrée et à la sortie des poulies 16,17 pour définir les deux brins de chaque voie, l'écartement des câbles 10, 12 étant légèrement augmenté sur des tronçons, avant et après les poulies pour les raisons décrites ci-dessous. La disposition des câbles 10, 12 est symétrique, le câble 10 à l'intérieur de la voie avant la poulie se trouvant à l'extérieur à la sortie et inversement, les deux boucles passant ainsi sur le même nombre de galets de guidage 92 et subissant un même freinage ou une même résistance de défilement.With particular reference to FIG. 15, it can be seen that the cables 10,12 pass over guide rollers 92 at the entry and exit of the pulleys 16,17 to define the two strands of each track, the spacing of the cables 10, 12 being slightly increased on sections, before and after the pulleys for the reasons described below. The arrangement of the cables 10, 12 is symmetrical, the cable 10 inside the track before the pulley being outside at the outlet and vice versa, the two loops thus passing over the same number of guide rollers 92 and undergoing the same braking or the same running resistance.

En se référant plus particulièrement aux fig. 16 à 19, on voit que les câbles 10,12 passent dans la station de mise sous tension 15 sur des poulies folles de renvoi 18,19 identiques, mais décalées latéralement d'une distance correspondant à l'écartement des câbles. Les poulies 18,19 sont montées sur des coulisseaux 94,95 mobiles suivant la direction générale de la ligne et sollicités par des vérins 96,9T dans le sens de mise sous tension des câbles 10,12. Les vérins 96,97 sont strictement identiques et alimentés par la même source de pression 98, de façon à fournir des tensions égales aux câbles 10,12, tout en compensant de faibles différences de longueur des boucles de câble 10,12. Les vérins 96,97 constituent un palonnier pouvant être mécanique. Les vérins 96,97 peuvent être remplacés par deux contrepoids outoutautre dispositif analogue. Le fonctionnement en ligne de la télécabine se passe de commentaire et seul le passage dans la station 15 est décrit ci-dessous en référence aux figures 18 à 23, le passage dans la station 14 étant identique. En admettant que les câbles 10, 12 défilent en synchronisme dans le sens indiqué par la=flèche sur les figures 18, 19, la voie inférieure sur la figure 18 constitue la voie d'entrée, c'est-à-dire la voie dc désaccouplement et de dégagement du véhicule 24 des câbles 10, 12 et la voie supérieure celle de sortie, en l'occurrence d'engagement et de réaccouplement du véhicule 24 aux câbles 10, 12.With particular reference to Figs. 16 to 19, it can be seen that the cables 10, 12 pass through the tensioning station 15 on idler idler pulleys 18, 19 which are identical, but laterally offset by a distance corresponding to the spacing of the cables. The pulleys 18.19 are mounted on sliders 94.95 movable in the general direction of the line and biased by jacks 96.9T in the direction of tensioning of the cables 10.12. The cylinders 96, 97 are strictly identical and supplied by the same pressure source 98, so as to provide equal tensions to the cables 10, 12, while compensating for slight differences in length of the cable loops 10, 12. The cylinders 96, 97 constitute a lifting beam which can be mechanical. The cylinders 96, 97 can be replaced by two counterweights or any other similar device. The on-line operation of the cable car speaks for itself and only the passage through station 15 is described below with reference to FIGS. 18 to 23, the passage through station 14 being identical. Assuming that the cables 10, 12 run synchronously in the direction indicated by the = arrow in FIGS. 18, 19, the lower channel in FIG. 18 constitutes the entry channel, that is to say that is to say the uncoupling and disengagement path of the vehicle 24 from the cables 10, 12 and the upper path the output path, in this case engagement and re-coupling of the vehicle 24 to the cables 10, 12.

Lorsque le véhicule 24 entre dans la station 15, les roues 68 du chariot 48 roulent sur les rails 26 représentés en traits mixtes, et les leviers 66 commandent l'ouverture de toutes les pinces 50 à 56 de la manière usuelle (position A, fig. 20). Les rails 26 dévient par la suite légèrement le chariot 48 vers le haut par rapport aux câbles 10, 12 pour dégager les pinces 50 à 56 des câbles 10, 12 (position B, fig. 21). En aval de la position B, vu dans le sens de défilement des câbles 10, 12, ces derniers passent sur des galets de guidage 92 à axe vertical pour diverger et attein- dre un écartement supérieur à la largeur totale du chariot 48, les mors 60, 62 étant en position ouvert. Dans cette zone la trajectoire des rails 26 s'abaisse par rapport aux câbles 10, 12, qui passent sous des galets de guidage 100 à axe horizontal pour dégager le chariot 48 vers le bas (position D, fig. 22 et position C, fig. 23), le chariot 48 passant sous les poulies d'extrémités 18, 19. Le ralentissement du véhicule 24 peut être engagé dès l'ouverture des pinces 50 à 56. La sortie de la station 15 est aménagée d'une manière symétrique pour l'accouplement des véhicules 24 aux câbles suivant les séquences inverses : passage du chariot 48 sous les poulies 18, 19, insertion du chariot entre les câbles 10, 12, rapprochement des câbles, enfourchement des mors sur les câbles avec synchronisation de la vitesse du chariot avec celle des câbles, et fermeture des pinces. La symétrie des deux boucles de câbles 10, 12 est conservée.When the vehicle 24 enters the station 15, the wheels 68 of the carriage 48 roll on the rails 26 shown in phantom, and the levers 66 control the opening of all the clamps 50 to 56 in the usual manner (position A, fig . 20). The rails 26 subsequently slightly deviate the carriage 48 upwards with respect to the cables 10, 12 to release the clamps 50 to 56 from the cables 10, 12 (position B, fig. 21). Downstream of position B, seen in the running direction of the cables 10, 12, the latter pass over guide rollers 92 with a vertical axis to diverge and reach a spacing greater than the total width of the carriage 48, the jaws 60, 62 being in the open position. In this zone the trajectory of the rails 26 is lowered with respect to the cables 10, 12, which pass under guide rollers 100 with a horizontal axis to release the carriage 48 downwards (position D, fig. 22 and position C, fig . 23), the carriage 48 passing under the end pulleys 18, 19. The slowing down of the vehicle 24 can be engaged as soon as the clamps 50 to 56 are opened. The outlet from the station 15 is arranged in a symmetrical manner for the coupling of vehicles 24 to the cables according to the reverse sequences: passage of the carriage 48 under the pulleys 18, 19, insertion of the carriage between the cables 10, 12, bringing the cables together, forcing the jaws on the cables with synchronization of the speed of the carriage with that of the cables, and closing of the clamps. The symmetry of the two cable loops 10, 12 is preserved.

Les véhicules 24 dégagés des câbles circulent dans la sta- ticn sur les voies usuelles de transfert et éventuellement de stockage, permettant un débarquement et embarquement des passagers à l'arrêt ou à vitesse réduite de circulation.The vehicles 24 disengaged from the cables run in the station on the usual transfer and possibly storage channels, allowing disembarkation and embarkation of passengers at a standstill or at reduced speed of circulation.

A la sortie les véhicules 24 sont réaccouplés aux câbles 10, 12 de la manière précitée. L'aménagement de l'autre station d'extrémité 14 est identique et n'a pas besoin d'être décrit. On peut remarquer que toutes ces opérations peuvent être facilement automatisées comme dans les télécabines conventionnelles et qu'elles s'effectuent sans arrêt du véhicule en ne nécessitant que des dispositifs classiques dont l'efficacité et la fiabilité ont été éprouvées.At the outlet, the vehicles 24 are re-coupled to the cables 10, 12 in the aforementioned manner. The layout of the other end station 14 is identical and need not be described. It can be noted that all of these operations can be easily automated as in conventional gondolas and that they are carried out without stopping the vehicle by requiring only conventional devices whose efficiency and reliability have been proven.

La capacité importante des véhicules permet de limiter le nombre de véhicules en ligne tout en assurant un débit notable et il est possible de stocker les véhicules 24 sur les rails de transfert 26 des stations en assurant un départ à la demande. On évite ainsi un fonctionnement à vide et toute usure inutile.The large capacity of the vehicles makes it possible to limit the number of vehicles in line while ensuring a significant throughput and it is possible to store the vehicles 24 on the transfer rails 26 of the stations while ensuring a departure on demand. This avoids empty operation and unnecessary wear.

La figure 24 illustre une variante de réalisation de l'invention dans laquelle la suspente 46 des véhicules 24 est articulée à un chariot 102, dont le châssis 104 en U encadre extérieurement les deux câbles 10, 12. Les pinces 50-56, portées par le châssis 104, sont orientées vers l'intérieur en direction des câbles 10, 12 enserrés par les mors 62 se faisant face. Les pylônes sont agencés en conséquence pour un libre passage du chariot 102, en montant les balanciers à galets de support 42 aux deux extrémités d'une traverse 106 s'étendant transversalement entre les deux câbles 10, 12. Cette disposition inverse ne modifie pas le fonctionnement de l'installation, mais nécessite un pincement des câbles 10, 12 dans les stations pour le dégagement ou l'engagement du chariot 104. L'agencement du chariot 104 est plus compliqué et plus encombrant, celui des pylônes étant par contre plus simple.FIG. 24 illustrates an alternative embodiment of the invention in which the line 46 of the vehicles 24 is articulated to a carriage 102, the U-shaped frame 104 of which externally frames the two cables 10, 12. The clamps 50-56, carried by the frame 104, are oriented inward towards the cables 10, 12 enclosed by the jaws 62 facing each other. The pylons are arranged accordingly for a free passage of the carriage 102, by mounting the rockers with support rollers 42 at the two ends of a crosspiece 106 extending transversely between the two cables 10, 12. This reverse arrangement does not modify the operation of the installation, but requires pinching of the cables 10, 12 in the stations for clearing or engaging the carriage 104. The arrangement of the carriage 104 is more complicated and more bulky, that of the pylons being on the other hand simpler .

Il est clair que l'invention est applicable à des installations ayant un nombre de pinces différent ou des pinces d'une structure différente.It is clear that the invention is applicable to installations having a different number of clamps or clamps of a different structure.

La fig. 25 montre un mode de mise en oeuvre préféré des balanciers de support des câbles 10, 12. Chaque balancier à galets de support 42 est porté par l'extrémité d'un bras 108, 110 articulé en 112, 114 à la potence 30 pour permettre un débattement dans le plan transversal aux câbles 10, 12. Une entretoise 116 relie les bras 108, 110 pour constituer un quadrilatère déformable maintenant les galets 42 parallèles et à écartement constant quel que soit le débattement des bras 108, 110.Fig. 25 shows a preferred embodiment of the cable support pendulums 10, 12. Each pendulum with support rollers 42 is carried by the end of an arm 108, 110 articulated at 112, 114 to the bracket 30 to allow movement in the plane transverse to the cables 10, 12. A spacer 116 connects the arms 108, 110 to constitute a deformable quadrilateral maintaining the rollers 42 parallel and at constant spacing whatever the travel of the arms 108, 110.

L'entraînement des poulies 16, 17 peut comprendre un différentiel électrique schématiquement représenté à la figure 26. Chaque poulie 16, 17 est entraînée par un moteur électrique 118, 120, parfaitement identique. Les deux moteurs 118, 120 sont reliés par des lignes d'alimentation 122, 124 à une même source de puissance électrique 126. Des appareils de mesure 128 insérés dans les lignes 122, 124 signalent en permanence l'intensité et la tension du courant d'alimentation de chaque moteur 118, 120. Les deux boucles de câbles étant symétriques les puissances fournies par les moteurs 118, 120 sont identiques et les intensités et tensions sont les mêmes. Il subsiste bien entendu toujours une légère dissymétrie qui se traduit par une différence des intensités et/ou tensions, mais cette différence de mesure peut être repérée ou compensée. En fonctionnement normal, les deux câbles sont entraînés à la même vitesse et la différence de mesure reste constante. Un incident, par exemple un accroissement de la résistance à l'avancement de l'un des câbles est automatiquement signalé par une variation de ladite différence de mesure et selon l'importance de cette variation, le défaut est simplement signalé ou provoque l'arrêt de l'installation.The drive of the pulleys 16, 17 may include an electrical differential shown diagrammatically in FIG. 26. Each pulley 16, 17 is driven by an electric motor 118, 120, which is perfectly identical. The two motors 118, 120 are connected by supply lines 122, 124 to the same source of electrical power 126. Measuring devices 128 inserted in the lines 122, 124 permanently signal the intensity and the voltage of the current d power to each motor 118, 120. The two cable loops being symmetrical, the powers supplied by the motors 118, 120 are identical and the currents and voltages are the same. There is of course always a slight asymmetry which results in a difference in the intensities and / or voltages, but this difference in measurement can be identified or compensated for. In normal operation, the two cables are driven at the same speed and the measurement difference remains constant. An incident, for example an increase in the resistance to advancement of one of the cables is automatically signaled by a variation of said measurement difference and depending on the magnitude of this variation, the fault is simply signaled or causes the stop of the installation.

La figure 27 illustre une vériante de réalisation dans laquelle les deux pinces 50,54, respectivement 52,56 sont superposées, les câbles 10,12 étant légèrement décalés en hauteur. Ce décalage peut correspondre à celui des poulies d'extrémités dans les stations.FIG. 27 illustrates a real embodiment in which the two clamps 50.54, respectively 52.56 are superimposed, the cables 10.12 being slightly offset in height. This offset may correspond to that of the end pulleys in the stations.
