Fig. 8 is a sectional view of a hydraulic twin cylinder drive units for actuating the telescopic device 7 of the drive 5 and 5 'according to FIGS. 1 to 3. It comprises the members of the telescopic device three guide tubes 25 and the disposed within these guide tubes 25 twin cylinder 16 with the associated supply lines 26 for hydraulic fluid. The twin cylinder 16 is double-acting, ie it can cause both a forced extension and a retraction of the chassis units 5 and 5 ', corresponding to a lifting of the container truck 1 when unloading from a transport vehicle or lifting one under the container truck container or transport frame.

When used, the loading system according to the invention has the advantage that it is with a transport vehicle, e.g. B. a semitrailer with associated trailer that can be used to hold containers or Swap bodies is equipped on this transport vehicle compact shape without exceeding that for transportation Road dimensions and regulations are transported can. The container pallet truck can then go to the desired location automatic, d. H. without additional devices, by swinging out the two-sided chassis units and off driving the telescopes with their wheels on the ground and raised sufficiently by this, the respective Anchoring the transport frame to the transport vehicle over the four ISO corners of the crossbars of the transport frame and the bolts on the transport vehicle have been loosened beforehand and the Bolts of the horizontal crossbeams of the container lift truck with the Keep the ISO corners of the transport frame engaged. To this The container lift truck also lifts the transport frame with and can drive it away from the transport vehicle and anywhere drop. The connections between the transport frame and the scales Right truss can then be opened by extending the truss be lifted so that the container pallet truck is unloaded and can drive over the transport frame, so that it is for a Containers are free. After picking up containers by appropriately extending and retracting the telescopic horizontal crossbeams and snap their bolts into the ISO Corners can then this container z. B. can be moved as desired or can also be loaded onto any transport vehicle, or containers can be removed from other transport vehicles be loaded, what the free container pallet truck over the on the Transport vehicle located container is driven and the Process of anchoring containers with the container pallet truck over the trusses or ISO corners.

In the loading system according to the invention, devices known in the art can of course be used, e.g. B. can drive the wheels of the chassis units via electric motors, internal combustion engines or hydraulic motors, the pivoting devices of the chassis units can be actuated electrically or hydraulically and the actuation of the devices for telescoping the chassis units can also be followed by electric motors or hydraulically via hydraulic cylinders. Advantageously, so-called hydraulic twin cylinders are used as devices for teles copying the undercarriage devices, as are shown in FIG. 8. The necessary units such as motors, accumulators, fuel storage containers etc. - both for the self-propelled container lift truck as well as for driving the horizontal telescopic trusses and for swinging in and out as well as telescoping the chassis units - can, for.
