[Effect of device]

Since the transportation pallet according to the present invention can be folded, for example, when automobile parts are loaded and transported to a foreign country by a container, etc., the automobile parts are taken out and then folded and collected. It is possible to Therefore, it can be used repeatedly, and the cost can be significantly reduced. Moreover, when the pallet is folded, the side frame bodies are held face to face in a butt shape on the same plane, and the front and rear frame bodies can be juxtaposed on top of each other, so that the pallet becomes compact and the folding thickness dimension is small, and even when stacked in multiple stages. Without being bulky,
Very good stackability. As a result, many pallets can be collected in a small space, and the recovery cost is low. Further, when stacking pallets, the positioning portion provided on the lower corners of the pallets is fitted on the mounting piece by being guided by the tapered guide surface at the upper end of the mounting piece, so that the pallets can be stacked in multiple stages and reliably. You can do it, and you won't fall. Further, since the pallet base is provided with the reinforcing rods that guide and regulate the forks such as forklifts from the outer surfaces on both sides, the insertability of the forks is extremely good. In addition, since each component is electro-deposition coated, the coating surface is strong, and all the surfaces of the component, such as the inner surface of the closed cross section, are also coated. Therefore,
Even if a fork such as a forklift hits it, the painted surface does not peel off, rust is reliably prevented, and rust does not adhere to the parts loaded on the pallet.
The quality of each part can be improved.
