Pallet for storing and transporting piece goods

The invention relates to a pallet for storage and transport of piece goods, consisting of a storage area and a number of feet, by means of which the storage area at a distance held by the ground. This gives the forks of a forklift truck free access from at least one side of the pallet made possible.

Such pallets are generally made of wood.

Accordingly, they have a number of disadvantages

! These disadvantages are that the material has a large weight

difference, depending on whether it is dry or wet, as follows:

I that a check weighing of the goods on the wooden pallet cannot be carried out with the desired reliability. On the other hand, these pallets have a not inconsiderable weight, which makes up 2 to 3% of the capacity of the maximum load, which also requires significant manual handling ¹ physical effort. In addition, reuse is generally impossible as the return transport costs prohibit this. They have to be dismantled accordingly, which is not without problems and causes further costs, whereby the material itself is irretrievably lost. Finally, in most cases it is necessary to fix the load in a complicated way in order to prevent displacement, since the flat surface of the loading area itself does not guarantee lateral stabilization.

The support beams, generally 3 to 4 in number, are vertical to the upwardly curved side reinforcement parts of the rectangular or square storage area or along it arranged in any direction of the surface with four upwardly curved side parts. The end girders can be at the same height as the edge of the storage surface so that the forks of the truck engage in the space between the beams.

As a further advantage, the pallets according to the invention can be simple can be made from existing elements, at an advantageous price, in large quantities and in a wide variety of designs be available. They easily compress so that they can be sold and recovered of the material is possible.

The P / rice of the pallet is so moderate that it can be reused by no means imposing. However, if re-use is sought, their durability ensures a long life length of time. It is also easy to clean and can, if necessary, with a protective coating made of metal or an art fabric material to be coated. Because her weight is essentially remains constant, and fluctuates only minimally from one pallet to another, the loaded goods can be transported without difficulty and without provisional tare determination can be determined. On the other hand, the weight is two to three times less than the corresponding one Pallets made of wood or metal, so that manual handling is possible without using special energy.
