The invention relates to utility vehicles with a lowerable to the ground for receiving a Superstructure equipped frame, the superstructure with lifting devices and with floor supports Is provided.

Such vehicles and their superstructures are known have floor supports at their front and rear ends that function as a telescopic lifting device works. The fact that most vehicles have the rear axle body and tires Reach approximately the same width, due to this version erne swing-out or extendable holder of the floor supports; because when the body is raised, the rear axle must be between the front supports can be driven through. Due to the many additional components that such Need superstructures, they become heavy and expensive.

The invention is therefore based on the object of creating a vehicle of the type mentioned above, with your own resources, you can also build large-volume structures in a preferably horizontal position can be set down on the ground or loaded from the ground without taking any special precautions the width of the vehicle must be taken.

According to the invention, this object has been achieved in that a lifting device between the vehicle frame and the front area of the body and running concurrently with it during operation acts on the rear floor supports.

The advantageous arrangement and mode of operation of the front lifting device based on parts of the chassis and the two rear floor supports running at the same time allow an almost horizontal Lifting and lowering of superstructures of every conceivable size; only the suspension of the chassis can cause an insignificant tilt. The engine of the truck is advantageously used as the power source used. By eliminating the front floor supports, a chassis with wider The rear axle can be driven under the superstructure or pulled forward unhindered.

The saving on additional components and thus the added weight and investment are significant and obvious.

The vehicle is advantageously developed in such a way that the lifting device is between the vehicle frame and the structure is arranged on the vehicle frame. On the vehicle frame lengthways Slidable lifting devices in the form of a crane are known.

It is also useful that the structure of the vehicle from one of pallets or containers separable lifting frame. Lifting frames that can be separated from the vehicle are also known.

Further useful explanations can be found in the remaining claims.

The invention is explained in more detail with reference to the embodiments shown in the drawing. It shows

F i g. 9 shows a second, expanded exemplary embodiment of a structure, placed on supports in front of a loading ramp.

On the vehicle frame 1, two rails 2 are attached, which are inclined at the rear end of the frame run down and close with a safety stop 9. Both sides at the rear end of the frame conical brackets that expand upwards are provided as a rear body stop 7 and serve as a carrier for start-up rollers 8. At the front, the running rails are secured by a roller stop 4 and a construction stop 5 completed.

Halfway along the length of the running rails 1 spring-loaded latches 6 are arranged on both sides of the frame, which secure the lifted structure during the journey. The container structure 21 is on a base frame 10 built. At the front there are two front wall supports, which are connected at the top by a yoke are. The front wall support advantageously have a U-shaped cross-section, wherein guide rollers 15 of the roller stool 13 run with rollers 14 of a lifting device 12. The hydraulic or mechanical lifting device 12 is articulated to the yoke of the end wall support part. In the rear corners of the container, mechanical or hydraulic floor supports 18 are installed on both sides.

built, which are connected to the front lifting device, work simultaneously. The construction frame 10 has eyelets 16 that match the spring-loaded latches 6 and counterstops 17 that match the stop 7 at the back on.

To pick up the body, the vehicle rolls backwards against the front of the body until the start rollers 8 reach the end wall supports 11. The truck engine, for example, serves as an energy source, then the connection line is now coupled. By extending the floor supports at the same time 18 and the lifting device 12 grip the rollers 14 in front of the safety stop 9 on the Running rails 2 and brace the structure up to the height of the fenders 3 of the vehicle. Well pushes the chassis under the structure until the rollers 14 hit the stop 4. The lifting device 12 and the floor supports 18 are retracted, thereby lowering the structure and sliding between the stops 5 and 7. With the help of the spring-loaded latch 6, the structure is fixed to the chassis tied together. A loaded superstructure is lowered to the ground in the reverse order, starting with the tensioning of the spring-loaded latch 6, extending the lifting device 12 and the floor supports 18 until the structure has risen above the height of the fenders 3. That The chassis rolls forwards under the body until the rollers 14 reach the safety stop 9, the lifting device 12 and the floor supports 18 retract, so that the rollers 14 lift one another the height of the safety stop 9. Finally, the connection line is disconnected and the chassis drove away.

A structure that can be placed on supports in front of a ramp 22 is arranged with two at the front under the loading level Folding supports 19 and with two socket pins 20 for the rear floor supports 18 in addition equipped.

Placing on supports begins with the tensioning of the spring-loaded latch 6 and is extended by extending the lifting device 12 and the floor supports 18 continued. The following additional operations are required: Pulling the chassis forward, folding down the supports 19 and inserting the socket pins 20 in at a suitable height in the row of holes in the floor supports 18 (not shown). Then the lifting device 12 and the floor supports 18 retracted until the socket pins 20 lock, the connecting line disconnected and driven away with the chassis.
