Pallet for truck

The invention relates to a pallet for a truck equipped with a tipping device 5. The pallet comprises (i) a base, (ii) upwardly extending sides extending to the rear edge of the base, and (iii) an openable stern deck spaced from the rear edge of the base in front of it, the rear end of the base forming a load-bearing rear end of the stern deck. extension, and whereby the bottom, sides and stern together delimit the load compartment.

The aim is to dimension the pallet for the transport of earth so that the weight of the evenly loaded load compartment is optimally distributed over the various axles of the truck. Such dimensioning enables, for example, visual loading with a wheel loader so that the statutory axle weights are not exceeded. The load is unloaded by tilting the pallet attached to the frame of the vehicle 20 by means of the tipping axle to such a position that the soil drains down.

The following are used for variable soil transport:. usually pallets with hydraulically operated headboards hinged at the top. This type of sternboard allows controlled drainage of soil during tipping, and thus, for example, the spreading of crushed stone into a flat mat by driving and tipping at the same time.

The distance between the tipping axle and the end point of the pallet bottom is usually called • 'crossing'. The longer this crossing is, the more stable the pallet is in tipping mode, as the weight of the unloading load balances the load. On the other hand, this crossing allows soil as long as possible, for example when tipping into a silo.

The problem in the construction of pallets for the transport of soil is how the benefits of crossing can be combined with load-bearing regulations. Indeed, there are often situations where the load-5 regulations force the load compartment to be positioned in such a way that a sufficiently long exceedance is not achieved without special measures. The problem applies in particular to four-axle trucks (with 2 front axles) and semi-trailers.

In known pallets, the problem has been eliminated even with solutions as complex as tipping backwards or bogie packages. However, there are two most common solutions. The first solution is to make the sides and bottom of the pallet as long as a suitable crossing requires and to delimit the load compartment 15 with a hinged tailboard from above so that the load compartment ends at a point suitable for load-bearing provisions before the actual pallet ends. In the second solution, in addition to a conventional top-hinged headboard, an additional stern hinged at its lower part to the outer edge of the pallet base 20 is used as the pallet rear, which remains parallel to the bottom of the pallet in its open position, i.e. continues when the bottom is tilted.

:. *. However, both structures described above have their own shortcomings, which are described below. In the first pallet according to its solution model, the driver must inspect and clean the post-stern deck after each loading and tipping. This is important for road safety, as the even large rocks can be left on the plateau, which can fall .30 unobstructed into other traffic while driving. Pallet according to another embodiment with an additional hinge at the bottom. stern, allows the soil to drain down the edges when tipping. If it is desired to prevent overflow, it is necessary to build edge guides, which are generally in the shape of a quarter, on the side surfaces of the stern board li 3 87638. For reasons of appearance and safety, the edge guides are designed to be constructed so that when the additional stern board is attached, the guides are inside the edge of the platform (in the space between the outer and inner panels of the edge 5). This construction has proven to be vulnerable in its operations, especially in winter, when the soil freezes at the corners of the guides and the sternboard, preventing the additional sternboard from closing. Forcibly closing the auxiliary stern in these 10 situations can in turn lead to the rupture of the stern. The construction has also proved to be short-lived, as the lack of space makes it difficult to design the edge guides to be sufficiently rigid against bumps caused by stones (in order to work, the edge guides must retain their shape).

The object of the present invention is to overcome the problems described above and to provide a new type of pallet which enables optimal weight distribution without the problems described above. This is achieved by a pallet 11a according to the invention, characterized in that the end of the side panels is provided with a space delimited by the rear part of the bottom and the rear part of the side sides: an additional sternboard closing the end so that the sternboard pushes the additional sternboard open.

The basic idea of the invention is to add to the structure according to the first solution described above an additional sternboard closing behind the plateau formed by the stern part of the bottom, so that the actual sternboard always acts as an opener and closer of the additional sternboard.

According to a preferred embodiment of the invention, the auxiliary sternboard is arranged in an inclined position on the inclined end surfaces of the side panels. This is how to. ···. place the auxiliary stern close to the actual stern in such a position that it rests on the largest possible surface 4 B7638 against the stern moving it, and yet the necessary overhang is obtained at the bottom.

The invention will now be described in more detail with reference to an example according to the accompanying drawing, in which Figure 1 shows a side view of a truck with a pallet according to the invention in a transport and loading position, and Figure 2 shows a side view of a truck with a pallet according to the invention. 10 with the pallet in the tipping position.

The figures show a pallet 3 mounted in a conventional manner on a truck 2 with a tipping device 1, comprising a base 4 and edges 5 extending upwards from its edges, extending (from their lower part) to the rear edge 15 4b of the base, and an openable tailboard 6 spaced from the rear edge of the base. 4b in front of it. The stern part 4 'of the base thus forms a load-extending extension behind the stern board 6. The base 4, the sides 5 and the stern-board 6 together delimit the load space 7. According to the invention 20, an additional pallet 8 of substantially the width of the pallet is arranged against the end faces 5b of the side panels. that their upper part comes in the immediate vicinity of the transom 6. The auxiliary stern is hinged at its top to the top of its stern 6. By forming side walls [| the end faces 5b are inclined to make the additional stern board 8 close to the actual stern board 6 in such a position that it rests on the largest possible surface against the stern board moving it, and yet the bottom is required to cross.

: In figure l, the pallet is in the transport and loading position. (lowered), in which case the auxiliary stern board closes the bottom. the plateau formed by the stern part 4 'behind the stern board 6.

'· * When the load is unloaded (Fig. 2), the headboard 6 is pushed open, 5 87638 while supporting the additional headboard 8 further to the open position. Correspondingly, when the stern board 6 closes, the stern board follows the stern board 6 downwards so far that, according to Fig. 1, it rests on the end surfaces 5b of the side boards.

Although the invention has been described above with reference to the example according to the accompanying drawing, it is clear that the invention is not limited thereto, but can be modified in many ways within the scope of the inventive idea set out in the appended claims. For example, the position of the stern-10 board and its hinge points may vary according to other construction.
