Description

  The present invention relates to a pallet used in combination with a transport means such as a forklift, and more particularly to a pallet with a transported article fall prevention function having a fall prevention function when a winding body is placed.

Conventionally, there are various types of pallets for transportation. Currently, flat pallets made of wood or resin are mainly used for roll-shaped winding bodies.
However, when transporting the winding body, since the winding core is generally transported horizontally, it is necessary to consider that it does not roll and fall on the pallet. Therefore, it is widely performed to manually set a stopper for preventing the fall. Further, a “pallet” (for example, Patent Document 1) in which a detachable stopper is provided in the vicinity of the end of the top surface of the pallet has been proposed.

In the case of the above-mentioned manual work, a fall accident may occur due to forgetting to set the load on the pallet or inadequate setting.
In addition, in the case of Patent Document 1, there is a drawback that the stopper becomes an obstacle when placing the winding body on the pallet or when stacking the pallet for storage.
Furthermore, in the case of Patent Document 1, the stopper must be removed from the pallet when stacking for storage or the like. Therefore, extra labor and management must be performed, and a separate storage space is required.
