As is well known, pallets are widely used both domestically and internationally, but transportation after being made into finished products is a major problem. Generally, the transportation radius for pallet sales is within 500 kilometers. If the transportation cost exceeds 500 kilometers, it will significantly increase. In order to solve this problem, we have put in effort in the design and designed a stackable nine legged tray. It can increase the transportation volume by more than three times, greatly reducing transportation costs.
