In particular, the display units had to be mounted in areas that were not safe or difficult to access without securing means. Furthermore, there was often the need to use additional lifting equipment for mounting the display units.
Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren zur Anordnung einer Anzeigeeinheit an einem Turmdrehkran zur Verfügung zu stellen, welches eine einfache und sichere Montage der Anzeigeeinheit ermöglicht. Weiterhin soll ein entsprechender Turmdrehkran bzw. eine entsprechende Anzeigeeinheit zur Verfügung gestellt werden.Object of the present invention is therefore to provide a method for arranging a display unit on a tower crane available, which allows easy and safe installation of the display unit. Furthermore, a corresponding tower crane or a corresponding display unit is to be made available.
Erfindungsgemäß wird diese Aufgabe durch ein Verfahren gemäß Anspruch 1 gelöst.According to the invention, this object is achieved by a method according to claim 1.
Das erfindungsgemäße Verfahren zur Anordnung einer Anzeigeeinheit an einem Turmdrehkran ist bei Turmdrehkranen einsetzbar, welche einen in der Arbeitsposition vertikal ausgerichteten Turm sowie einen am Turm um eine horizontale Schwenkachse schwenkbar angebrachten Ausleger aufweisen. Das erfindungsgemäße Verfahren umfasst dabei die folgenden Schritte: Absenken des Auslegers durch Verschwenken um die horizontale Schwenkachse; zumindest teilweises Anbringen der Anzeigeeinheit am Ausleger in der abgesenkten Position; und Anheben des Auslegers durch Verschwenken um die horizontale Schwenkachse. Durch das Absenken des Auslegers kann die Anzeigeeinheit erfindungsgemäß vom Boden aus montiert werden, so dass die Montage sowohl einfacher als auch sicherer wird. Weiterhin werden auch keine zusätzlichen Hebezeuge zur Montage der Anzeigeeinheit benötigt.The inventive method for arranging a display unit on a tower crane can be used in tower cranes, which have a vertically aligned in the working position tower and a pivotally mounted on the tower about a horizontal pivot axis boom. The inventive method comprises the following steps: lowering of the boom by pivoting about the horizontal pivot axis; at least partially attaching the display unit to the boom in the lowered position; and raising the boom by pivoting about the horizontal pivot axis. By lowering the boom, the display unit according to the invention can be mounted from the ground, so that the assembly is both easier and safer. Furthermore, no additional hoists for mounting the display unit are needed.
Erfindungsgemäß wird dabei die Auslegerspitze zur Montage der Anzeigeeinheit vorteilhafterweise in einen sicheren Bereich abgesenkt, in welchem eine ungefährdete Montage der Anzeigeeinheit möglich wird.According to the invention, the jib tip for mounting the display unit is advantageously lowered into a safe area, in which a safe mounting of the display unit is possible.
Vorteilhafterweise ist dabei erfindungsgemäß der Ausleger in seiner Arbeitsposition im wesentlichen horizontal ausgerichtet oder um die horizontale Schwenkachse nach oben verschwenkt. Erfindungsgemäß wird nun der Ausleger zum Anbringen der Anzeigeeinheit aus seiner Arbeitsposition in eine Stellung verschwenkt, in welcher der Ausleger um die horizontale Schwenkachse nach unten verschwenkt ist. Insbesondere ist der Ausleger dabei so weit nach unten verschwenkt, dass die Auslegerspitze sich in einem sicheren Bereich befindet. Weiterhin vorteilhafterweise wird der Ausleger erfindungsgemäß nach dem Anbringen der Anzeigeeinheit wieder zurück in seine Arbeitsposition verschwenkt. In dieser dient er nun als Träger für die Anzeigeeinheit. Vorteilhafterweise ist der Ausleger in dieser Position im wesentlichen horizontal ausgerichtet.Advantageously, according to the invention, the boom is aligned in its working position substantially horizontally or pivoted upwards about the horizontal pivot axis. According to the invention, the boom for attaching the display unit is now pivoted from its working position into a position in which the boom is pivoted down about the horizontal pivot axis. In particular, the boom is pivoted so far down that the boom tip is in a safe area. Further advantageously, the boom according to the invention is pivoted back to its working position after attaching the display unit. In this he now serves as a carrier for the display unit. Advantageously, the boom is oriented substantially horizontally in this position.
Weiterhin vorteilhafterweise weist der erfindungsgemäße Turmdrehkran eine Unterbaueinheit und eine auf der Unterbaueinheit um eine vertikale Drehachse drehbar gelagerte Drehbühne auf, welche den Turm trägt. Beim einem solchen erfindungsgemäßen Turmdrehkran wird demgemäß der gesamte Turmaufbau zum Drehen des Auslegers gedreht.Further advantageously, the tower crane according to the invention comprises a substructure unit and a rotary platform rotatably mounted on the substructure unit about a vertical axis of rotation and supporting the tower. In such a tower crane according to the invention, accordingly, the entire tower structure is rotated to rotate the boom.
Weiterhin vorteilhafterweise ist dabei der Ballast für den Turmdrehkran auf der Drehbühne angeordnet. Bei solchen Turmdrehkranen kann üblicherweise der Ausleger als Ganzes um die horizontale Schwenkachse gegenüber dem Turm abgesenkt werden.Furthermore advantageously, the ballast for the tower crane is arranged on the revolving stage. In such tower cranes usually the boom can be lowered as a whole about the horizontal pivot axis relative to the tower.
Bei der Unterbaueinheit kann es sich dabei erfindungsgemäß sowohl um ein Standpodest, als auch um einen Unterwagen handeln, durch welchen der Turmdrehkran zusammengelegt transportiert werden kann.According to the invention, the substructure unit can be both a stand pedestal and an undercarriage through which the tower crane can be transported folded.
Weiterhin vorteilhafterweise handelt es sich bei dem erfindungsgemäßen Turmdrehkran um einen Mobilbaukran, welcher einen verfahrbaren Unterwagen, einen auf dem Unterwagen drehbar angeordneten Oberwagen sowie eine auf dem Oberwagen angeordnete Krananordnung aufweist, welche sich selbsttätig zu einem Turmdrehkran aufrichten kann.Further advantageously, the tower crane according to the invention is a mobile construction crane which has a movable undercarriage, a superstructure rotatably mounted on the undercarriage and a crane arrangement arranged on the superstructure, which can erect itself to a tower crane.
Vorteilhafterweise ist erfindungsgemäß auf der Drehbühne eine Abspannwinde angeordnet, durch welche ein Abspannseil zum Abspannen der Auslegeabspannung bewegt wird. Vorteilhafterweise erfolgt das Absenken und das Anheben des Auslegers dabei durch Betätigung der Winde.Advantageously, according to the invention, a guy winch is arranged on the revolving platform, through which a guy rope is moved for unclamping the lay-up tension. Advantageously, the lowering and the lifting of the boom is done by operating the winch.
Weiterhin vorteilhafterweise kann erfindungsgemäß der Ausleger in gestreckter Position, das heißt ohne zusammengeklappt zu werden, um seine Schwenkachse nach unten verschwenkt werden.Further advantageously, according to the invention, the boom in the extended position, that is to be folded without being folded about its pivot axis down.
Der sichere Bereich, in welchem die Auslegerspitze vorteilhafterweise zur Montage der Anzeigeeinheit abgesenkt wird, kann dabei je nach Größe und Ausführung des Turmdrehkrans unterschiedlich groß ausfallen. Vorteilhafterweise wird die Spitze des Auslegers dabei auf eine Höhe von weniger als 10 Metern über dem Boden abgesenkt, weiter vorteilhafterweise auf eine Höhe von weniger als 7 Metern, weiterhin vorteilhafterweise auf eine Höhe von weniger als 5 Metern.The safe area in which the cantilever tip is advantageously lowered for mounting the display unit can be different in size depending on the size and design of the tower crane. Advantageously, the tip of the boom is thereby lowered to a height of less than 10 meters above the ground, more advantageously to a height of less than 7 meters, further advantageously to a height of less than 5 meters.
Insbesondere wenn es sich um einen Mobilbaukran handelt, besteht der Turm üblicherweise aus einem oder mehreren Turmteilen. Vorteilhafterweise wird dann die Auslegerspitze in einen Höhenbereich abgesenkt, welcher sich unterhalb des Höheniveaus eines halben Turmteiles befindet. Weiterhin vorteilhafterweise wird die Auslegerspitze in einen Höhenbereich abgesenkt, der sich zwischen dem Höheniveau der Unterbaueinheit und dem Höhenniveau des halben Turmteils befindet. In diesem Bereich kann die erfindungsgemäße Anzeigeeinheit problemlos und gefahrlos montiert werden.In particular, if it is a mobile construction crane, the tower usually consists of one or more tower parts. Advantageously, the cantilever tip is then lowered into a height range which is below the height level of half a tower part. Further advantageously, the jib tip is lowered into a height range which is between the height level of the sub-unit and the height level of the half-tower part. In this area, the display unit according to the invention can be easily and safely mounted.
Vorteilhafterweise wird dabei der gesamte Montagebereich für die Anzeigeeinheit in den sicheren Bereich abgesenkt.Advantageously, the entire mounting area for the display unit is lowered into the safe area.
Vorteilhafterweise handelt es sich bei dem erfindungsgemäßen Turmdrehkran um einen Kran, bei welchem der Turm eine Höhe von mehr als 15 Metern, weiterhin vorteilhafterweise von mehr als 30 Metern aufweist. Weiterhin vorteilhafterweise handelt es sich bei dem Ausleger des erfindungsgemäßen Turmdrehkrans um einen Gitterausleger. Der Ausleger kann dabei aus einem oder mehreren Auslegerteilen bestehen. Insbesondere wenn es sich um einen Mobilbaukran handelt, sind dabei vorteilhafterweise mehrere Auslegerteile vorgesehen, welche jeweils drehbar aneinander gelagert sind und so zum Transport des Kranes zusammengeklappt werden können.Advantageously, the tower crane according to the invention is a crane, in which the tower has a height of more than 15 meters, more advantageously more than 30 meters. Further advantageously, the boom of the tower crane according to the invention is a lattice boom. The boom can consist of one or more boom parts. In particular, if it is a mobile crane, advantageously more boom parts are provided, which are each rotatably mounted to each other and so can be folded to transport the crane.
Weiterhin vorteilhafterweise handelt es sich bei dem erfindungsgemäßen Turmdrehkran um einen Laufkatzen-Turmdrehkran. Dabei ist eine Laufkatze vorgesehen, welche am Ausleger verfahrbar gelagert ist und über welche das Hubseil mit dem Lasthaken geführt ist.Further advantageously, the tower crane according to the invention is a trolley tower crane. In this case, a trolley is provided, which is movably mounted on the boom and over which the hoist rope is guided with the load hook.
In der einfachsten Ausführung der vorliegenden Erfindung kann die Anzeigeeinheit ohne Zuhilfenahme der Laufkatze oder des Hubseils zum Beispiel durch Verschrauben an mindestens zwei Befestigungspunkten am Ausleger montiert werden.In the simplest embodiment of the present invention, the display unit without the aid of the trolley or the hoist rope can be mounted, for example by screwing on at least two attachment points on the boom.
Vorteilhafterweise erfolgt bei dem erfindungsgemäßen Verfahren die Montage der Anzeigeeinheit jedoch durch Verfahren der Laufkatze und/oder des Hubseils. Zur Montage der Anzeigeeinheit können somit Hebezeuge bzw. Antriebe eingesetzt werden, welche ohnehin bereits am Kran vorhanden sind. Hierdurch kann auf die Verwendung externer Hebezeuge verzichtet werden.Advantageously, however, in the method according to the invention, the assembly of the display unit is carried out by moving the trolley and / or the hoist rope. For mounting the display unit hoists or drives can thus be used, which are already present on the crane anyway. This makes it possible to dispense with the use of external hoists.
Vorteilhafterweise wird erfindungsgemäß die Anzeigeeinheit zuerst an einem ersten Bereich am Ausleger befestigt und dann durch Betätigung der Laufkatze und/oder des Hubseils komplett am Ausleger angeordnet. Dieses Vorgehen hat den Vorteil, dass die Anzeigeeinheit zunächst nur in einem Bereich am Ausleger angeordnet werden muss, welcher besonders leicht zugänglich ist, insbesondere an der am niedrigsten angeordneten Auslegerspitze. Die restliche Montage kann dann unter Zuhilfenahme der Laufkatze und/oder des Hubseils erfolgen. Vorteilhafterweise kann der Rest der Montage dabei erfolgen, ohne dass ein Monteur bis zur Montagestelle am Ausleger gelangen muss.Advantageously, according to the invention, the display unit is first attached to a first region on the boom and then arranged by actuation of the trolley and / or the hoisting rope completely on the boom. This procedure has the advantage that the display unit initially only has to be arranged in a region on the boom, which is particularly easily accessible, in particular on the lowest arranged boom tip. The remaining assembly can then be done with the aid of the trolley and / or the hoist rope. Advantageously, the rest of the assembly can be done without a fitter has to get to the mounting point on the boom.
Vorteilhafterweise wird erfindungsgemäß die Anzeigeeinheit durch Betätigung der Laufkatze und/oder des Hubseils in einen zweiten Bereich, welcher weiter von der Auslegerspitze entfernt ist als der erste Bereich, mit dem Ausleger in Kontakt gebracht. Vorteilhafterweise wird die Anzeigeeinheit dabei in der montierten Position am Ausleger arretiert. Die Arretierung kann dabei durch eine automatische Arretierung oder durch einen Anschlag erfolgen.Advantageously, according to the invention, the display unit is brought into contact with the boom by actuating the trolley and / or the hoisting rope in a second area, which is farther from the jib tip than the first area. Advantageously, the display unit is locked in the mounted position on the boom. The locking can be done by an automatic lock or by a stop.
In einer ersten Montagevariante kann dabei die Anzeigeeinheit mit einem ersten Ende um eine horizontale Drehachse drehbar am Ausleger befestigt werden. Erfindungsgemäß wird dann das andere Ende mittels der Laufkatze und/oder des Hubseils an den Ausleger herangezogen. Insbesondere wird dabei das vordere Ende der Anzeigeeinheit im Bereich der Auslegerspitze um eine horizontale Drehachse drehbar am Ausleger befestigt. Das hintere Ende der Anzeigeeinheit kann nun mit der Laufkatze und/oder dem Hubseil verbunden werden und dann durch Bewegung der Laufkatze und/oder des Hubseils an den Ausleger herangezogen werden.In a first assembly variant, the display unit can be fastened with a first end about a horizontal axis of rotation rotatably on the boom. According to the invention then the other end is used by means of the trolley and / or the hoisting rope to the boom. In particular, the front end of the display unit in the region of the cantilever tip is mounted rotatably about a horizontal axis of rotation on the boom. The rear end of the display unit can now be connected to the trolley and / or the hoist rope and then be used by movement of the trolley and / or the hoisting rope to the boom.
Vorteilhafterweise wird hierfür am Ausleger mindestens eine Umlenkrolle angeordnet, über welche ein Seil geführt wird, über das die Anzeigeeinheit an den Ausleger herangezogen wird. Bei dem Seil kann es sich dabei um ein Hilfsseil handeln, welches mit einem Ende an der Anzeigeeinheit und mit dem anderen Ende an der Laufkatze befestigt wird. Durch Verfahren der Laufkatze kann dann die Anzeigeeinheit über das Hilfsseil an den Ausleger herangezogen werden. Dort kann die Anzeigeeinheit dann zum Beispiel automatisch über einen Schnappmechanismus arretiert werden. Alternativ kann hier auch nur ein Anschlag vorgesehen sein, so dass die Arretierung der Anzeigeeinheit durch Arretierung der Laufkatze erfolgt.Advantageously, for this purpose, at least one deflection roller is arranged on the boom, over which a cable is guided, via which the display unit is used to the boom. The rope may be an auxiliary rope attached at one end to the display unit and at the other end to the trolley. By moving the trolley, the display unit can then be used via the auxiliary cable to the boom. There, the display unit can then be automatically locked, for example, via a snap mechanism. Alternatively, only one stop can be provided here, so that the locking of the display unit takes place by locking the trolley.
Alternativ kann die Anzeigeeinheit auch direkt über das Hubseil angehoben werden, insbesondere indem der Lasthaken an der Anzeigeeinheit befestigt wird.Alternatively, the display unit can also be lifted directly over the hoist rope, in particular by the load hook is attached to the display unit.
In einer weiteren Alternative des erfindungsgemäßen Verfahrens wird die Anzeigeeinheit mit einem Ende am Ausleger verschiebbar gelagert und dann mittels der Laufkatze und/oder des Hubseils am Ausleger entlanggezogen. Auch hierdurch ist eine problemlose Montage der Anzeigeeinheit möglich. Hierbei kann die Anzeigeeinheit so geformt sein, dass sie über dem Ausleger angeordnet ist und durch Bewegung der Katze und/oder des Lasthakens über den Ausleger gezogen wird, wobei zur formschlüssigen Führung vorteilhafterweise die Auslegerform selbst dient.In a further alternative of the method according to the invention, the display unit is slidably mounted with one end on the boom and then pulled along by means of the trolley and / or the hoisting rope on the boom. This also makes a problem-free installation of the display unit possible. Here, the display unit may be shaped so that it is arranged above the arm and is pulled by movement of the cat and / or the load hook on the boom, wherein the form of form itself is advantageously used for positive guidance.
Vorteilhafterweise wird erfindungsgemäß eine Anzeigeeinheit eingesetzt, welche weniger als die Hälfte, weiterhin vorteilhafterweise weniger als ein Viertel, weiterhin vorteilhafterweise weniger als ein Sechstel der Länge des Auslegers aufweist. Dies hat zum einen den Vorteil, dass die Montage komplett in dem sicheren Bereich erfolgen kann.

Ebenso sind als Anzeigeelement verschiedene elektrische oder elektronische Medien wie beispielsweise LED, OLED oder andere elektronische oder elektrische Displays denkbar.The display unit according to the invention consists of a carrier system, a display element and an adaptive quick-mounting device for the connection to the crane boom. The carrier system may be, for example, a frame with fastening elements for the display element. The display element is advantageously an information or visualization element, e.g. Print media such as posters or textile banner may include. Similarly, as a display element various electrical or electronic media such as LED, OLED or other electronic or electrical displays conceivable.
Weist die erfindungsgemäße Anzeigeeinheit eine elektrische oder elektronische Anzeige auf, so benötigt sie hierfür eine Stromversorgung. Vorteilhafterweise ist die Stromversorgung dabei steckerfertig an der Anzeigeeinheit montiert. Vorteilhafterweise läuft die Stromversorgung dabei über die vorhandene Stromversorgung des Kranes.If the display unit according to the invention has an electrical or electronic display, it requires a power supply for this purpose. Advantageously, the power supply is plug-in mounted on the display unit. Advantageously, the power supply runs over the existing power supply of the crane.
Die erfindungsgemäße Anzeige kann dabei sowohl unter dem Ausleger, als auch über dem Ausleger angeordnet werden. Ist die Anzeigeeinheit unter dem Ausleger angeordnet, so bildet sie im Querschnitt vorteilhafterweise ein Dreieck, wobei die oben angeordnete Grundfläche unterhalb der Grundfläche des Auslegers angeordnet ist und die beiden Seitenflächen Anzeigeelemente tragen.The display according to the invention can be arranged both under the boom, as well as above the boom. If the display unit is arranged under the arm, it advantageously forms a triangle in cross section, wherein the arranged above the base surface is arranged below the base surface of the boom and the two side surfaces carry display elements.
Vorteilhafterweise werden erfindungsgemäß relativ kleine Anzeigeeinheiten eingesetzt, welche maximal ein Viertel der Fläche einnehmen, welche durch Ausleger und Turmstück beschrieben werden. Hierdurch wird die Standsicherheit bei Windfreistellung bis zu hohen Windstärken garantiert. Hierdurch ist keine Überwachung der Anzeigeeinheit auch bei hohen Windstärken erforderlich.Advantageously, relatively small display units are used according to the invention, which occupy a maximum of a quarter of the area, which are described by boom and tower section. As a result, the stability is guaranteed at wind release up to high wind speeds. As a result, no monitoring of the display unit is required even at high wind speeds.
Die Länge der Anzeigeeinheit beträgt erfindungsgemäß vorteilhafterweise weniger als die Hälfte der Länge des Auslegers, weiterhin vorteilhafterweise weniger als ein Viertel, weiterhin vorteilhafterweise weniger als ein Sechstel. Hierdurch ist zum einen eine sichere Montage im sicheren Bereich 11 möglich. Zum anderen werden auch die Windlasten entsprechend klein gehalten.The length of the display unit according to the invention advantageously less than half the length of the boom, more advantageously less than a quarter, further advantageously less than a sixth. As a result, on the one hand a safe installation in the

Der Ausleger wird über eine Auslegerabspannung 35 abgespannt, welche am Turmkopf über Abspannstützen 36 und 37 umgelenkt wird. Zum Ansenken und Aufrichten des Auslegers ist dabei eine längenveränderliche Abspannung 38 vorgesehen, welche von der Auslegerabspannung 35 nach unten zur Drehbühne 6 geführt ist, wo eine entsprechende Winde zur Bewegung der Abspannung 38 vorgesehen ist.

Vorteilhafterweise wird bei dem erfindungsgemäßen Verfahren die Informationseinheit 10 zunächst in einem ersten Bereich 13 an der Auslegerspitze 10 um eine Drehachse drehbar befestigt. Danach wird die Informationseinheit 10 zum Ausleger angehoben und in einem zweiten Bereich 14, welcher weiter von der Auslegerspitze 12 entfernt ist, arretiert. Die Verriegelung kann dabei zum Beispiel federbetätigt folgen, wobei ein Lösen zum Beispiel durch einen Seil- bzw. Bodenzug erfolgen kann. Es sind jedoch, wie bereits oben dargestellt, auch manuelle Verriegelungen wie zum Beispiel Anschrauben, Anbolzen oder ähnliches denkbar. Weiterhin sind auch Verriegelungsmöglichkeiten nach dem Kugelschreiberprinzip, ähnlich einer 2-4-Strangumscherung denkbar. Selbstverständlich sind auch elektrisch oder hydraulisch betätigbare Verriegelungsmöglichkeiten denkbar.Advantageously, in the method according to the invention, the

Die Aufhängung im Bereich der Auslegerspitze stellt so einen Drehpunkt zum Anheben der Anzeigeeinheit 10 an den Ausleger zur Verfügung. Weiterhin ist ein Hilfsseil 18 vorgesehen, das an der Laufkatze 21 an einem Befestigungspunkt 23 befestigt wird. Dieses wird über eine Hilfsseilumlenkung mit Umlenkrollen 19 und 20, welche am Ausleger angeordnet sind, zur Anzeigeeinheit 10 geführt. Das Hilfsseil 18 ist dabei an der Anzeigeeinheit 10 in einem von der Drehachse 15 beabstandeten Bereich angeordnet, im Ausführungsbeispiel am hinteren Ende der Anzeigeeinheit 10. Durch Katzfahren nach innen wird die Anzeigeeinheit 10 nun durch das Hilfsseil 18 in ihre Endlage angehoben.The suspension in the area of the jib tip thus provides a fulcrum for raising the
Die Anzeigeeinheit 10 weist dabei eine zweite Aufhängung 17 auf, welche so ausgebildet ist, dass sie die Anzeigeneinheit 10 in ihrer Endlage zum Ausleger hin fixiert. Hier kann zum Beispiel ein Anschlag und/oder eine zusätzliche Verriegelung stattfinden. Ist nur ein Anschlag vorgesehen, so kann die Anzeigeeinheit in ihrer Endlage durch ein Verriegeln der Laufkatze fixiert werden. Die Verriegelung kann jedoch auch wie oben bereits dargestellt erfolgen.The

Die Montage der Anzeigeeinheit kann auch unter Zuhilfenahme des Lasthakens erfolgen. Auch hierfür wird die Anzeigeeinheit 10 nur einseitig an der Auslegerspitze eingehängt. Der Lasthaken hebt die Anzeigeeinheit dann direkt in ihre Endlage, wobei das Anheben im wesentlichen wie bereits hinsichtlich der

Die Demontage der erfindungsgemäßen Informationseinheit erfolgt dann in sämtlichen Ausführungsbeispielen jeweils in umgekehrter Reihenfolge.The disassembly of the information unit according to the invention then takes place in all embodiments in each case in the reverse order.
In Fig. sind mehrere Ausführungsvarianten einer weiteren Ausführungsform einer erfindungsgemäßen Anzeigeeinheit dargestellt. Die Anzeigeeinheit 10 umfasst dabei eine oder mehrere bewegliche Klappen, welche über Scharniere 29 an der Grundform des Auslegers angelenkt sind. Diese Ausführungsform könnte eventuell auch fest an der Auslegerspitze verbleiben. Die eingefahrene Stellung (Transportstellung) wird dabei manuell oder mit Unterstützung der Laufkatze und/oder der Hakenbewegung erreicht.In Fig. Several variants of a further embodiment of a display unit according to the invention are shown. The
Durch die erfindungsgemäße Absenkung des Kranauslegers zur Montage der Anzeigeeinheit ergibt sich eine einfache, schnelle (1 bis 10 Minuten), wartungsarme sowie sichere und kostengünstige Montage einer Anzeigeeinheit, insbesondere zu Werbe- und Informationszwecken, an einem Kranausleger. Durch die einfache Handhabung kann die Montage sowie die Demontage im Einmannbetrieb vorgenommen werden, was sich wiederum positiv auf die Kosten sowie die Geschwindigkeit der Montage auswirkt. Erfindungsgemäß kann eine verbesserte Kranauslastung erreicht werden, da der Kran in Zeiten, in welchen er nicht zum Hubbetrieb benutzt wird, als Werbeträger eingesetzt werden kann.The inventive lowering of the crane boom for mounting the display unit results in a simple, fast (1 to 10 minutes), low maintenance and safe and cost-effective installation of a display unit, especially for advertising and information purposes, on a crane boom. The ease of use, the assembly and disassembly can be made in one-man operation, which in turn has a positive effect on the cost and speed of assembly. According to the invention, an improved crane utilization can be achieved since the crane can be used as an advertising medium in times when it is not used for lifting operation.
Da die Anzeigeeinheit als abnehmbares System umgesetzt wird, ist diese sehr flexibel verwendbar. Dadurch, dass zur Montage der Anzeigeeinheit im wesentlichen auf die bereits am Kran vorhandene technische Ausrüstung zurückgegriffen wird, sind lediglich geringfügige Modifikationen am Kran notwendig.Since the display unit is implemented as a detachable system, it can be used very flexibly. The fact that the display unit is used essentially for the technical equipment already present on the crane only requires minor modifications to the crane.
Die durch die Absenkung des Kranauslegers zur Montage mögliche Anordnung der Anzeigeeinheit in einem sicheren Bereich in der Nähe des Bodens wird ohne weitere Hilfsmittel eine schnelle und sichere Montage bzw. Demontage erreicht.The possible arrangement of the display unit in a safe area in the vicinity of the ground by the lowering of the crane jib for mounting a quick and safe installation and removal is achieved without further aids.
