Description

A PALLET OF HIGH RIGIDITY HEXAGON STRUCTURE < RTI ID = 0.0 >

The present invention relates to a pallet. More particularly, the present invention relates to a pallet for use as a pallet for supporting a cargo when a cargo is unloaded using a forklift or the like.

The pallet is a kind of pallet used for loading and unloading work using a forklift or the like. The pallet is formed to have a constant vertical size so as to be stacked in a certain quantity unit in order to enhance the efficiency of the unloading through standardization of the cargo.

(Patent Document 1), the pallet according to the prior art mainly uses wood, but insects are parasitized in the wood to cause quarantine problems in each country and damage to the products, thereby improving the pallet made of synthetic resin.

The pallet made of synthetic resin has a structure in which a plurality of support parts are integrally formed between the upper panel panel and the lower panel panel having a space formed by integrally forming a plurality of support pieces and reinforcing pieces, Respectively.

Here, (Patent Document 1) discloses that supporting strength of a pallet made of synthetic resin is crossed to form auxiliary reinforcing flesh to increase the structural strength of the pallet to improve the supporting force for supporting the weight of the cargo.

However, the pallet formed of a synthetic resin according to (Patent Document 1) has a problem in that it is heavy in weight. That is, the pallet is made up of synthetic resin, for example, at each corner for supporting and supporting the cargo, and nine pillars disposed therebetween, except for the space formed between the support and reinforcement pieces and the fork insertion space.

Therefore, the pallet formed of the synthetic resin according to Patent Document 1 has a problem that the weight of the pallet itself is heavy and the amount of the synthetic resin itself required for manufacturing the pallet itself increases.
