Stacking plates (pallets) made of reinforced plastic.

Stacking plates are used for the transport and stacking of goods of the most varied Kind of used in connection with forklift trucks, fork lift trucks.

The invention relates to a stacking plate which, in particular in the specified dimensions according to DIN, consists of a plastic reinforced with fiberglass chips and which is brought together from a number of details.
There are stacking plates (pallets) known that

a) consist of wood, these are nailed together from individual boards and blocks.

b) consist of thermoplastic material, which is injection-molded from one piece, according to the design and injection molding technology heavily ribbed and thus have a specifically small floor contact area.

c) made of a duromer plastic, also consisting of one piece and therefore, in terms of casting tool technology, also have an extremely small floor area.

r. d) so-called one-way pallet, consisting of pressed cardboard or resin-μ. bonded wood-chip materials, which are not discussed further here.

f The so-called stacking plates have individual disadvantages that

\ should be eliminated by the subject matter of the invention explained below.

(, It has been shown in practice that the so-called wooden pallets in the relatively rough

Sri ^ _#

When handling forklifts or similar, the service life is short, Ϊ this is largely dependent on the type of wood. Specifically, these flat pallets are used or stored in closed trees to dry out, but are exposed to free weathering elsewhere, so that in addition to the rough load in use, wear and tear of Lzw. It becomes unusable because the wood, as an organic material, absorbs moisture and thus expands unevenly, and especially starting from the nail points, splits, so that the structural stability is no longer given and the service life is severely impaired. Under certain circumstances, this can already be the case with wooden stacking panels that are relatively new. This fits both in the. Storage as well as in the transport sector, the concerns of the general safety regulations can be impaired to a considerable extent, can also be recognized.

The aforementioned plastic pallets untor b * c create this deficiency recognized from. In detail, however, it shows that this Pallets have ribbed floor support surfaces due to the processing technology production in such a way that with a given load-bearing capacity or load, the specific floor pressure, especially in the case of truck beds and egg. <3 railway wagons, whereby the floors consist of wood, becomes too large and thereby increased wear and tear and damage to it Soils.

These also require plastic pallets, especially when stacked and when using TC in high-bay warehouses due to hollow storage the Use or arrangement of an additional 'Htteltraverse to reduce the size the support'Veiten and given deflection due to t'berbeansnrucVmng.

Due to the one-piece design and the conditional, high production costs, Taking into account the rough operation in practice, a repair or restoration of the rtifier stacking plates is not given, whereby the 'economy' factor is also impaired. All of the flat pallets mentioned above are subject to wear harder, rough deposits, 3-surface concrete floor, box fastenings with Slag, solite bitumen, stone paving, etc. - exposed. The object of the invention aims to achieve these remarkable above to improve or to avoid completely the disadvantages mentioned. Predictions Here is a flat pallet made of several details, with the upper part consisting of one piece with three identical lower part cross members verraittelä tongue and groove fixings arranged in several places and suitable gluing or screwing with a force-fit connection will. In this way, a composite body is achieved which, due to its structural strength of the individual parts, which is already given by ribbing, corresponds in principle and in static terms to the structural strength of a lattice girder.

By using several details, one is for plastic, manufacturing-related design possible, whereby a sufficiently large Floor loading or contact area and therefore a small specific one Floor pressure is achieved at a given load. The same is the design of the three identical lower part traverses given in such a way that an application of such a pallet under load is possible on transport rollers, rollers or flanged rollers. At the same time, this creates free space at the respective points, which the arrangement in these appropriate places of

Bolt enables, which means that tensioning straps ο.Λ. the corresponding stored or conveyed goods can be clamped without these belts disturbing the receiving arra of industrial trucks, nor the belts, belts oi \ by these arms when the loaded! pallets are picked up. Destroyed, crushed or damaged, as is often the case with conventional pallets and with straps that are pulled underneath. The composition of the pallet made up of several individual parts, as stated here, guarantees the replacement of the corresponding individual part - too much lower parts - and therefore extensive reuse or an increase in the service life of the stowed pallet in the event of impairing damage. In addition to the, from the use dee material Kxmststoff f ^r ir these already well-known advantages of low weight, the constant weight in a cross-border traffic. As a result of the hydroscopic character, the use of closed-cell rigid foam with a hard, firm outer skin, which is reinforced as a whole by glass fiber chips, is proposed, which, in particular, due to the corresponding glass fiber reinforcement and the sandwich character, provides the required rigidity and strength under full load and with brings about all the advantages of other flat ralettes made of plastic.

To increase the surface wear on rough shelves harder granulates, grains or balls made of stone or ceramic materials such as glass, quartz sand, etc. embedded in the surface skin, which at the same time significantly increases the slip resistance. Are emphasized on the basis of the choice of material and the constructive Design so that neither splitting nor breaking off of edges can take place automatically or carelessly, so that in addition to the economic, given advantage, security concerns are better guaranteed. There is a more rational labeling and Labeling without an additional work step of printing on thereby, that corresponding, interchangeable font duplicates are attached in the corresponding molding tool.
