Zuvor bekannte zum Schleppen bzw. Tragen von Lasten dienende auf einem Fußboden oder entlang einer anderen Unterlage verfahrbare Lasttransportvorrichtungen erhalten die zur Lenkung erforderlichen Impulse über starre mechanische Stangen von einem oberhalb der Fahrunterlage angeordneten Schienensystem, das zugleich als Stromschienen-Zuführsystem dient. Ein Nachteil bei diesen ist der Umstand, daß die längs des Schienensystems bewegliche Stromabnahmevorrichtung fortlaufend starken ziehenden bzw. schiebenden Kräften aligesetzt ist, die die Leitflächen der Vorrichtung oder ihre Räder beanspruchen, wobei sich in der elektrischen Stromzufuhr zu den Schleifkontakten Störungen ergeben können.Previously known for towing or carrying loads serving on a Load transport devices that can be moved along the floor or along another surface receive the impulses required for steering via rigid mechanical rods from a rail system arranged above the driving surface, the simultaneously serves as a busbar feed system. A disadvantage with these is the fact that continuously strengthen the current collection device that is movable along the rail system pulling or pushing forces are all set, which the guide surfaces of the device or claim their wheels, taking in the electrical power supply to the Sliding contacts can result in malfunctions.

Vorliegender Erfindung liegt die Aufgabe zugrunde, hier Abhilfe zu schaffen und die eingangs genannte Transportvorrichtung so auszubilden, daß eine Entlastung der Stromabnahmevorrichtung und gleichzeitig eine störungsfreie Stromzufuhr zu den Schleifkontakten gewährleistet wird.The present invention is based on the object of remedying this create and train the aforementioned transport device so that a Relief of the current collection device and at the same time an interference-free power supply to the sliding contacts is guaranteed.

Die erfindungsgemäß vorgesehene Lasttransportvorrichtung kennzeichnet sich dadurch, daß die in dem Stromschienen-Zuführsystem bewegliche Stromabnahmevorrichtung eine eigene Antriebsmaschinerei aufweist, mittels der sie sich längs des Schienensystems bewegt, und daß das Ubertragungsglied ein biegsames Torsionskabel ist. Somit entstehen zwischen der Stromabnahmevorrichtung im Schienensystem und der Lasttransportvorrichtung keine hohen schiebenden odeniehenden Kräfte mehr, sondern ausschließlich geringe Tosionskräfte zur Lenkung. Die Stromzufuhr von dem Schienensystem zur Lasttransportvorrichtung vollzieht sich auf diese Weise einwandfrei.The load transport device provided according to the invention is characterized by the fact that the current collection device, which is movable in the busbar supply system has its own drive machine shop, by means of which it moves along the rail system moved, and that the transmission link is a flexible torsion cable. Thus arise between the current collection device in the rail system and the load transport device no more high pushing or pulling forces, but only low ones Tosion forces for steering. The power supply from the rail system to the load handling device works perfectly in this way.

Eine günstige Ausführungsform der Erfindung wird erreicht, wenn die im Stromschienen-Zuführsystem bewegliche Stromab.E-mevorrichtung Schleifkontakte aufweist, über welche die Lasttransportvorrichtung die erforderlichen Funktions- und LenK-befehle erhält. Man kann der Lasttransportvorrichtung Funktionsbefehle über zusätzliche Leiter im Stromschienen-Zuführsystem, Schleifkontakte und Verbindungsleiter erteilen. Mittels derartiger Befehle kann man u.a. die Fahrtrichtung der Lasttransportvorrichtung verändern, dieselbe anhalten, gewünschte Wendebewegungen ausführen, Zusatzmechanismen an der Lasttransportvorrichtung in Gang setzen und anhalten usw.A favorable embodiment of the invention is achieved if the current collector device, movable in the busbar feed system, sliding contacts has, via which the load transport device the necessary functional and receives LenK commands. Function commands can be given to the load handling device via additional conductors in the busbar feed system, sliding contacts and connecting conductors To give. Such commands can be used, among other things, to determine the direction of travel of the load transport device change, stop the same, execute desired turning movements, additional mechanisms start and stop at the load handling device, etc.
