Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet used when moving cargo with a forklift or the like.

Conventionally, wood is generally used as a material for pallets that are used to transport cargo by forklifts in factories, warehouses, and the like. However, wooden pallets are perishable and cannot be used for a long time. In recent years, lightweight pallets such as synthetic resin pallets and aluminum alloy pallets have become popular, and aluminum alloy pallets in particular are excellent in chemical resistance during cleaning, weather resistance, and recyclability after disposal. Therefore, it is widely used (see, for example, Patent Document 1).

The aluminum alloy pallet described in Patent Document 1 is composed of a pair of girders parallel to each other and a plurality of deck boards orthogonally welded between the upper parts of the pair of girders.

JP-A-2006-36308

However, conventional aluminum alloy pallets such as those described in Patent Document 1 are assembled by welding, which requires skill in welding technology, and there is a problem that welding tends to vary depending on the welder. rice field.

In addition, since the deck boards must be aligned and temporarily fixed before welding, there is a problem that the assembly work is complicated and the processing cost is greatly increased.

Furthermore, the aluminum alloy pallet described in Patent Literature 1 has a problem that it takes time and effort to repair when a part of the pallet is damaged.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and its object is to provide a pallet which can be easily assembled and which can greatly reduce the processing cost. .
