  • the outrigger arm may simply comprise two articulated beams relatively pivotable about an axis which is vertical or substantially so in the in-use position, one of the arms being for connecting at its other end to the vehicle for pivotal movement about a vertical or substantially vertical axis, and the other end of the other arm being connected to the planer head so that the planer assembly can pivot about a vertical or substantially vertical axis.

  • the vehicle may be a JCB type vehicle provided with a back hoe, or it may be an excavator of the wheeled or tracked type, or it may be a commercial tractor or commercial truck.
  • the vehicle provides a means on the one hand of transporting the equipment to the site, and on the other hand a weight transfer means as it is desirable that there should be downward vertical loading on the planer assembly 26 during operation.
  • the outrigger arm and the planer head can be raised clear of the ground, or lowered to the ground and by continued pressurising of the ram, the weight of the vehicle can be transferred via the frame 3 and the outrigger beams 5 and 6 to the planing head 26.
  • the planing head 26 comprises a frame 14 which is connected to the arm 6 via a universal joint 21.
  • the frame 14 is provided with depth control and ground engaging rollers 11. In fact any number of rollers 11 from one to six may be employed.
  • the frame 14 carries a pivotable steering shaft rotatable about vertical axis 23, and attached to this shaft is a manipulating handle 20 or tiller for use by an operator 20A.
  • the shaft supports a ground engaging drive wheel 10 which is drivable by means of a power source such as a hydraulic motor or other motor 27.

  • this figure shows the extent to which the cutting head 26 can be manipulated by the operator.
  • the cutting drum can travel anywhere in the area 22, and this manipulation is achieved by relative pivoting of the beams 5 and 6 and also by the capability of pivoting resulting from the utilisation of universal joint 21.

  • the arms 5 and 6 are jack knifed close to the vehicle so that the cutting head can be positioned as shown, and to illustrate the extent of possible pivoting, the arm 5 is shown in a third position 5C.
  • the power unit 26 is essentially similar to that shown in Fig. 1 and parts equivalent to those parts described in relation to Fig. 1 carry similar reference numerals.
  • the handle 20 has an operating trigger 2OB which can be raised and lowered to effect " forwards and reverse drive of the traction motor 27 for forwards and reverse driving of the wheel 10.
  • the trigger is controlled by the operator 20A and is a "dead man" trigger 2OB in that if the operator releases the trigger 2OB it will return to the neutral position and driving of the unit 26 will stop.
  • the arm sections 5 and 6 are box section beams which telescopically interfit to enable the effective length of the outrigger arm to be adjusted or adjust automatically.
  • the end of beam 6 which fits into beam 5 has two rollers Rl and R2 which run on the inside of beam 5 to ensure smooth low friction telescoping, whilst encouraging the effective transfer of the weight of the vehicle to the unit 26 through the arm 5, 6 in that the two rollers Rl and R2 provide a reactive moment between the beam sections 5, 6.

  • arms C and D are pivotally interconnected at B which defines an horizontal axis
  • A also indicates the horizontal pivot axis connection between arm C and the vehicle.
  • the entire arm assembly can swing about a vertical axis adjacent the vehicle, but the machine could be modified where the slew arm assembly is adapted to float, which would allow the arm C to work through the same angle of movement basically as arm 5 in the embodiment of Figs. 1 and 2.
  • the application of hydraulic pressure into rams E and F could enable the arms C and D to act as a weight transfer means from the tractor onto the planer head G.
  • Other machines on the market could be adapted to operate in a similar manner. Even without adaptation, it is believed that the machine of Fig. 4 could still operate in the general concept of the present invention in that the planer G again is provided with a separate steerable drive wheel and hand tiller.
  • planing head 26 can be independently driven in any portion of the area of operation 22 and can be manipulated and steered by the operator 20A using handle 20 on pivot 23.

  • the hydraulic ram 1 is lowered until rollers 11 and wheel 10 engage the ground 18.
  • the extent of lowering of the ram 1 is dependent upon the amount of weight transfer which is required to be applied to the planer 26.
  • the prime mover is in fact by this means partially raised.

  • the motor 25 is rotating the cutter at this time. The operator can now by controlling the motor
  • the movement of the head, in which the outrigger arm functions as an umbilical or free moving connection providing weight and power transfer is by the driving of the motor 27, which may be a creep speed hydraulic motor and it is preferred that the direction of movement of the planer assembly is such that the motor 27 travels in advance of the planer assembly or direction X in Figs. 1 and 3.
  • Motor 27 will be provided with a speed control valve to increase or decrease the speed of movement of the planer head as desired (see 20B in Fig. 3), and this control is also fitted with a forward or reverse so that should the cutter drum 16 stall or become jammed, then the motor 27 will drive the wheel 10 in reverse.
  • a tractor loader as shown in Fig. 4 When a tractor loader as shown in Fig. 4 is provided with a sweeper collector bucket J, then there may be no need for the stabiliser legs H as shown in Fig. 4 as it is desirable to transfer the whole of the weight of the rear of the tractor whereby the rear of the tractor can be lifted onto the planer head 26. In the Fig. 1 and 2 arrangement, it is also possible using ram 1 to transfer nearly the whole of the vehicle weight onto the planer head 26.
  • the vehicle body will probably simultaneously be used for either containing hot bitumous materials and/or for collecting the planings produced by the planing cutting, so that there should be present considerable weight on the vehicle chassis which will be transmitted to the planer head via the outrigger arm.

Abstract

La présente invention concerne un appareil de travaux routiers dans lequel un ensemble (26) d'aplanissement de route est prévu. Cet ensemble (26) est conçu pour être man÷uvré par un opérateur (20A) bien qu'il possède son propre entraînement pour déplacer l'ensemble d'aplanissement sur la surface (17) de la route. L'ensemble d'aplanissement (26) est relié à un véhicule (24) au moyen d'un bras de gouverne (5, 6) dont la longueur effective est réglée pour que l'engin d'aplanissement (26) puisse être déplacé sur une surface substantielle sous la conduie de l'opérateur (20A). Cette disposition, grâce à une liaison appropriée avec le véhicule (24), permet de transférer une partie du poids du véhicule (24), par l'intermédiaire du bras de gouverne (5, 6) sur l'ensemble d'aplanissement (26) de sorte que la pousée vers le bas sur l'engin d'aplanissement (28) contribue à assurer une pénétration effective du rouleau aplanisseur dans la surface de la route (17) de manière à enlever une couche de l'épaisseur désirée (18).
