Plastic pallet

The invention relates to thermoplastic pallets Material and a method for their manufacture.

about the loading of objects of all kinds in the form of To facilitate bulk goods or in packaging, in particular by means of forklifts, plates are known to be used which commonly referred to as pallets. .

The great advantage of these pallets is that the Storage of goods, their loading on wagons, trucks or other means of transport as well as unloading without any changes to the pallets for the respective operation can be done.

These pallets are made of different materials, in particular made of metal, wood or plastic.

Juxe metal pallet is used because of its high price used very rarely.

The .fäletten made of wood usually use "time" through impacts off, through which pieces of wood and nails are torn out,

which leads to the fact that the pallets their cohesion and their · Lose stability. In addition, wood can soak itself up with water, which means that the individual pallets vary greatly in weight can. Finally, the cleaning and possibly sterilization of such pallets is difficult, if not impossible, which limits their use, especially in the food industry.

These various powers and deficiencies are made up for by one Pallet made of plastic parked, and there are already such plates, which are formed in one piece by injection molding will. However, complex and therefore very expensive machines are required for this manufacturing process.

The object of the present invention is to provide an improved method for producing pallets from thermoplastic Material and thus to create new pallets from thermoplastic material.

Bas process for the production of pallets according to the invention is characterized in that the individual parts of the pallets made of thermoplastic material by means of connecting parts » be assembled, these items on the one hand consist of beams and on the other hand of cross members that the Form the bottom and top of the pallet.

The pallets according to the invention are characterized in that aie consist of several parallel bars, which are connected to the cross members by means of holding elements, which form the bottom and top sides of the pallets

The individual parts made of plastic from which the pallets are assembled are made by known molding processes manufactured; They are light in weight and can be used by machines and tools; low capacity produced will.

Each of the individual parts of the pallet can "if damaged can be easily disassembled, making repairs simple and "cheap; on the other hand," in the case of one-piece Plastic pallets the whole pallet unusable, even if only part of it is "damaged".

Further details, features and advantages of the invention emerge from the following description of an exemplary embodiment based on the drawing.
