Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a rigid frame and a load carrier that can be moved from the bottom to the travel position.
The present invention relates to a truck having an exchangeable load carrying container comprising a lifting device for raising it to the bottom position and lowering it from the driving position to the bottom.

A typical truck with a high loading surface is
It is possible to load and unload cargo, but with difficulty. Additionally, the vehicle is unavailable for other purposes during the loading operation, resulting in the vehicle being unusable. To ensure better use of the vehicle,
Container vehicles have been developed which include a container that can be removed by a crane from the vehicle as a load carrying container and replaced by another container.

While containers are being loaded and unloaded, vehicles may be on the road to transport other containers if necessary. Loading and unloading of containers is carried out at specific stations by cranes or by lifting devices mounted on vehicles. In the latter case, the lifting device raises the container from the loading surface and into the vehicle area.
The container must be swung out of the way and finally placed into position. This is the associated swing system in lifting equipment.
system). It is not possible to handle heavy loads in this way. This is because there is a risk of the vehicle turning over.

The object of the invention is to provide a truck of the type mentioned at the outset of this specification, with which a load carrying container can be lowered and readmitted into a vehicle without pivoting movements.

To solve this problem, according to the present invention,
The frame surrounds the three load carrying containers and is open in a downward direction.

As a result, the load-carrying container is suspended on the frame, and the load-carrying container is of course locked to the frame in such a way that, in the traveling position, a firm contact is ensured between the load-carrying container and the frame. There is. When lowering the load carrier, the lock is released to lower the load carrier to the bottom. The load carrying container can then be moved out of the vehicle area. Its advantages lie not only in the simple exchange of the load carrier by vertical movement, but also in the possibility of lowering the load carrier to the bottom without having to completely remove it from the vehicle.

The unloading of heavy loads from the load carrying container is thus facilitated.

The load carrier can be a closed container, but it can also have a frame structure with open sides. In the latter case, the sides are fully available for loading and unloading operations. A vehicle equipped with such a load carrying container is particularly suitable as a beverage delivery truck for stacked cases of beverage bolts or for entire palletized loads. Despite the frame structure of the load carrying container with open sides, it is of course possible to take care that a lateral fall of the load is avoided. Load carrying containers can be covered with waterproof canvas (tarpaulin). If a truck is used to transport the beverage bolts, the load carrying containers can be loaded individually at the transfer station, but the entire vehicle need not remain there unused. Once the load carrier is loaded, it is transferred under the frame of the vehicle, lifted by the vehicle, and locked into the frame.

If it is intended to unload individual parts of the load at the delivery location, the load carrying container can be lowered so that the load can be accessed from the side at a suitable height. Once a defined portion of the load has been lowered, the load carrying container can be raised to the traveling height again.

According to a preferred embodiment of the invention, the frame surrounds the front and rear end faces of the load carrying container, the frame has at least one beam for bridging the load carrying container and for removal of the load carrying container. At least one side of the frame is open.

The load carrying container can be moved out of the vehicle area by a lateral displacement so that the vehicle can proceed later. This lateral displacement can be effected, for example, by means of rollers mounted on the bottom of the load carrier, the longitudinal axis of the vehicle being perpendicular to the axis of rotation of the rollers. Said lateral displacement can also be carried out on a roller conveyor or other conveyor device. The load carrying container is lowered onto a roller conveyor and moved laterally. Such conveyors may be used, for example, at loading points and at bulk buyers.
It only needs to be provided for loading and unloading cases of beverage bottles at the destination of the purchaser. This is because, in any case, at the destination of the small purchaser, only a portion of the load is unloaded, and therefore the load carrying container is not removed from the truck and the load carrying container is left in place. . However, it is advantageous to be able to lower the load carrying container to facilitate unloading of a portion of the load.

The lifting device preferably has at least two parts supported on the frame and engaging the load carrying container.
It consists of two lifting elements. Lifting elements suitable for this purpose are, for example, piston-cylinder units, rack and pinion drives, screw spindle drives, cable lines and the like.

According to one aspect of the invention, the entire frame can be raised and lowered together with the load carrying container.
To this effect, the lifting device consists of at least two lifting elements supported on the axle and engaging the frame. In order to retain the load carrying container in the frame, the front and rear supports of the frame can be provided with transverse slots in their front and rear walls, so that the load can be secured in the lowered state of the frame and the load carrying container. A load carrying container can be introduced into the slot by means of pins provided in the front and rear walls of the carrying container. Safe locking and suspension of the load carrying container in the frame is possible with a simple construction.

According to a preferred embodiment of the invention, the engine of the truck is mounted on the rear axle and after the load carrier, and the supply and signal lines extend above the load carrier between the forward cab and the engine. ing.

Specific examples of the present invention will be described in more detail with reference to the accompanying drawings.

The truck according to FIGS. 1 to 3 has a rigid frame 10 on the horizontal front end 11 of which a cab 12 is mounted. The vertically extending front support 13 is located at the horizontal front end 1 of the frame 10.
1 and extending vertically via a horizontal beam 14;
5. The supports 13 and 15 and the beam 14 open in a downward direction and close the load carrying container 1
6 forms an inverted U-shaped frame structure bridging over its entire length in side view of the truck. The rear support body 15 extending in the vertical direction includes
An engine 17 is attached. To avoid using a propulsion shaft extending the entire length of the vehicle, the vehicle is equipped with a rear engine and rear axle drive. Front axle 18 and rear axle 19
is suspended from the frame 10 via springs and attenuation elements.

As can be seen from FIG. 3, two beams 14 (shown in plan) are provided which extend parallel to each other. It is possible to provide transverse or diagonal struts between the beams.

The box profile of the load carrying container 16 is quadrilateral. Preferably, its sides are open, but the remaining four walls (bottom, ceiling, front wall and back wall) are closed. Front wall 20 of load carrying container 16
And on the outside of the rear wall 21 there is provided a protruding extension, an engagement member 22 , which can be engaged downwardly with a lifting element 23 supported on the frame 10 . In the illustrated embodiment,
The lifting element 23 is a piston-cylinder unit which is flexibly mounted between the two front supports 13 and between the two rear supports 15.

A lifting element 23 extending substantially vertically engages the engagement member 22 in its lower part to raise the load carrying container 16 from the lowered position shown in FIG. 2 to the traveling position according to FIG. In this position, the load carrying container 16 is lower engaged by the L-shaped locking element pawl 24. The pawl is hinged to the frame 10 and can be automatically latched when the load carrying container 16 reaches its uppermost final position. As a result, the load carrying container 16 is fixedly connected to the frame 10 when in the traveling position.

FIG. 6 is a perspective view of the bottom of the cargo carrying container 16 viewed from below. In FIG. 6, parts of the front wall 20 and rear wall 21 of the cargo carrying container 16 and the ceiling are omitted. A plurality of rollers 40 are attached to the bottom surface of the load carrying container 16. roller 4
0 is attached parallel to the longitudinal direction of the load carrying container 16. The outer peripheral surface of the roller 40 protrudes from the bottom surface of the load carrying container 16. As a result, when the load carrying container 16 is lowered to the ground,
The load carrying container 16 can be easily moved in a direction across the frame 10.

In the embodiments of FIGS. 4 and 5, frame 1
0 is of substantially the same design as the frame 10 of the first embodiment. However, in contrast thereto, the frame can be lowered as a whole relative to the axles 18 and 19, and at the same time, as is clear from FIG. 5, the cab 12 and the engine 17 are also lowered.

In this case, the front lifting element 30 is supported on the front axle 18 , while the rear lifting element 31 is supported on the rear axle 19 . Upper end frame 10 of both lifting elements 30 and 31
engages a member to which it is firmly connected.

The front support 13 and the rear support 15 have transverse slots 32 which extend almost horizontally on the inside of the support and are open to the side of the vehicle. In this slot a pin 33 can be introduced which projects outwardly from the front and rear walls of the load carrying container 16. The lateral slots 32 allow the load carrying container 16 to be inserted into the frame 10.
It has click-stop recesses to prevent movement of the pin 33 when installed in the correct position by lateral displacement against the pin.
By this means the load carrying container 10 is "suspended" within the frame by the pin 33 and it is
When raised from the lowered position shown in the figure, the frame 10 is also raised at the same time. Furthermore, locking elements (not shown) can be provided in order to avoid vibratory movements of the load carrier during travel.
