Loading plank for vehicles, large containers and the like,

The invention relates generally to load-bearing platforms, and is particularly, but not exclusively, concerned with with the loading planks of transportable large containers (containers) or the platforms of vehicles.

709819/0281

When loading or unloading platform trucks, transportable Large containers and the like. It may be necessary to carry heavy loads between the front and rear ends to move the loading plank carrying the loads. To facilitate such a shift, it is known to Slideways, e.g. roller tracks, are to be provided on the loading board.

Such lanes should desirably be designed to retract under the bed after loading can be so that parked loads during transport on the load-bearing surface in their position be held, and a lifting device should be provided to lift the slideways above the loading area, if this should be appropriate for the purposes of loading or unloading.

The object of the invention is to provide an improved lifting device to propose which is effective and reliable in use, but simple in construction and low in cost caused.

According to the invention is therefore in a load-bearing loading plank with at least one from the front to the rear End of extending slideway between an extended position at which it is over the loading area protrudes and a retracted position in which it is is located in or below the level of the loading area, is movable, with an associated lifting device, by means of whose sliding path between the retracted and the raised position can be moved, provided that the Lifting device essentially consists of at least one inclined ramp and a sliding member for the cooperating with it Slideway consists, one of which is assigned to the slideway, the other of which is assigned to the loading area, with a drive device for mutual relocation of inclined ramp and sliding link

is provided, by means of which the slide is raised.

By means of this arrangement, it is possible to move the slideway upwards even when it is loaded Way to control that uneven lifting and / or jamming of the slide - by tilting and the like. - Avoided or at least reduced to a minimum. Effective and reliable handling can thus in one simple and inexpensive construction.

In a preferred embodiment, the slide has a plurality of preferably designed as wheels or rollers Sliding members are attached to the slideway and cooperate with fixed inclined ramps.

The drive device is preferably a hydraulic press, although any other suitable pusher device can be used can be used for this.

In a preferred embodiment, there is one in the loading area Number of parallel slideways provided, each of which is designed as a roller conveyor and accordingly each consist of a steel bed with rollers mounted in the side walls.

The invention is described below using an exemplary embodiment with reference to the drawing; in this show:

Fig. 1 shows a broken away part of a loading area with the devices according to the invention in perspective front view;

FIG. 2 shows the arrangement of FIG. 1 in cross section with the slideway in the extended, excavated position Position;

3 shows the same in the same representation with the slide in the retracted, sunk position;

Fig. 4 the same in side view in a schematic

Representation to illustrate the anti-vibration device.

The loading area should represent the bottom of a large container (container) or the platform of a platform truck or the like. and consists of flat floorboards 1 made of wood, which are on a rigid steel framework of transverse beams 9 and longitudinal beams 2 rest and are attached. Four longitudinal channels 3 are provided in the floor covering of the loading board, which extend from the front of which extend to the rear end, of which two longitudinal channels near the two long sides and two near the Central axis of the loading area are arranged.

Inside each longitudinal channel 3 a slide is mounted, each of which consists of a long steel bed 4 with angled outward Side walls 5 and a plurality of rollers 6 arranged in parallel at a small distance from one another, which the latter are rotatably mounted in the side walls 5 and protrude slightly above the steel bed 4.

The steel bed 4 is made up of a plurality of dividing its length Sections built up that are welded together end to end. On the side walls of the steel bed 4 are outside wheels 7 mounted near the respective ends of the sections. The wheels 7 work with the inclined surfaces of ramps 8 together, which are formed on the lower flanges of the longitudinal channel 3 delimiting double angle girders as from Side members 9 rest. The ramps 8 rise in the direction of the rear end of the loading platform.

The slideway is shorter than the associated longitudinal channel 3 and allows the slide to move along the longitudinal

axis in that the wheels 7 on the inclined ramps 8 between a retracted and an extended one Slide along position. In the retracted position (Fig.3) are the wheels 7 at the lower ends the inclined ramps 8 and rest on the lower inwardly directed flanges of the double angle bracket 9, wherein the outwardly cranked side flanges 5 of the steel beds 4 on the upper outwardly directed flanges the double angle bracket 9 sit on and the entire slide is below the level of the surface of the floor boards 1 is located. In the extended position are the Wheels 7 at the upper end of the inclined ramps 8 and the slide is opposite the retracted position to the rear and laid upwards so that the rollers 6 protrude above the surface of the floor boards 1. Extends in both positions the slideway is horizontal and parallel to the plane of the loading plank.

A drive device in the form of a hydraulic press 10 enables each slide to be shifted backwards and thereby by means of the wheels 7 and inclined ramps 8 to effect their displacement into the elevated position. The repatriation the slide in the retracted position can be done simply by relieving the hydraulic press. the The press is at one end on the bottom of the slide bed 4, with the other end on a suitable part, e.g. a cross member 2 or any other part of the steel framework. The direction of force is approximately parallel to the inclined plane of the surface of the inclined ramps 8.

With the arrangement described above, the method of the slideways in a carefully controllable manner Use of simple and inexpensive construction parts can be made. In particular, there is little or no Determine the tendency of the slideways to jam or to uneven movement.

709819/0281

The invention is of course not limited to details of the embodiment described above, which only as Representation of an exemplary embodiment are to be understood. For example, the inclined ramps 8 do not have to be as described for the one described Embodiment only rise backwards, but it is just as well possible to make an arrangement at which they rise forward.
