Sofern die obere Umlenkrolle und/oder die untere Umlenkrolle vertikal einstellbar angeordnet ist, kann auf einfache Weise eine Spannvorrichtung für das Zugmittel gebildet werden.If the upper deflection roller and / or the lower deflection roller is arranged vertically adjustable, a tensioning device for the traction means can be formed in a simple manner.
Zweckmäßigerweise ist an dem Hubschlitten ein von klappbaren Gabelzinken gebildetes Lastaufnahmemittel vorgesehen und ist die Anhängevorrichtung an einer schwenkbaren Quertraverse des Hubschlittens angeordnet, wobei die Quertraverse mit den klappbaren Gabelzinken in Wirkverbindung steht. Die Anordnung der Anhängevorrichtung an einer schwenkbaren Quertraverse des Hubschlittens ermöglicht auf einfache Weise, dass bei ausgeklappten Gabelzinken die Anhängevorrichtung eingeschwenkt ist und nicht in den Lastaufnahmebereich ragt, wodurch auf einfache Weise verhindert wird, dass die auf den Gabelzinken befindliche Ladung durch die Anhängevorrichtung beschädigt werden kann. Durch die klappbaren Gabelzinken weist das Flurförderzeug in der Funktion als Schlepper mit eingeklappten Gabelzinken geringe Abmessungen auf. Mit einer Quertraverse kann hierbei auf einfache Weise die Anhängevorrichtung verschwenkt und gleichzeitig die Gabelzinken geklappt werden, wodurch ein schneller Wechsel des erfindungsgemäßen Flurförderzeugs von der Funktion als Schlepper in die Funktion als Gabelstapler und ein sicherer Betrieb in der jeweiligen Funktion erzielbar ist.Conveniently, a load-receiving means formed by folding forks is provided on the lifting carriage and the towing device is arranged on a pivotable cross-beam of the lifting carriage, wherein the cross-beam is operatively connected to the folding forks. The arrangement of the hitch on a pivoting cross-beam of the lifting allows in a simple way that when the fork arms folded out the hitch is pivoted and does not protrude into the load receiving area, which is easily prevented that the charge located on the forks can be damaged by the hitch , By the foldable Fork has the truck in the function as a tractor with folded forks small dimensions. With a crossbeam this can be easily pivoted the hitch and at the same time the forks are folded, whereby a quick change of the truck according to the invention from the function as a tractor in the function as a forklift and safe operation in the respective function can be achieved.
Sofern gemäß einer bevorzugten Ausführungsform der Erfindung die Quertraverse mit einer Antriebsvorrichtung, insbesondere einem als Elektrozylinder ausgebildeten elektrischen Linearantrieb, in trieblicher Verbindung steht, sind die Anhängevorrichtung sowie die klappbaren Gabelzinken mittels lediglich einer Antriebsvorrichtung betätigbar, wodurch der Bauaufwand des erfindungsgemäßen Flurförderzeugs weiter verringert wird. Die Ausbildung der Antriebsvorrichtung als Elektrozylinder ermöglicht ohne Hydraulikanlage einen sicheren Betrieb des Flurförderzeugs in ergonomisch günstiger Weise ohne körperliche Anstrengungen, da das Ausschwenken der Anhängevorrichtung und das Klappen der Gabelzinken mittels der Antriebsvorrichtung von der Bedienperson ohne den Bedienarbeitsplatz verlassen zu müssen durchgeführt werden kann. Hierdurch wird weiterhin ein schnelles und zeitsparendes Klappen der Gabelzinken und Verschwenken der Anhängevorrichtung erzielt, wodurch mit dem Flurförderzeug eine hohe Umschlagleistung erzielt werden kann.If according to a preferred embodiment of the invention, the cross-beam with a drive device, in particular designed as an electric cylinder electric linear drive is in drive connection, the hitch and the folding forks are actuated by means of only one drive device, whereby the construction cost of the truck according to the invention is further reduced. The design of the drive device as an electric cylinder allows without hydraulic system safe operation of the truck in an ergonomically favorable manner without physical effort, since the pivoting of the hitch and the flaps of the forks can be performed by the operator without the operator workstation to be performed by means of the drive device. As a result, a quick and time-saving flaps of the forks and pivoting of the hitch is still achieved, which can be achieved with the truck, a high handling capacity.
