[0002] As we all know, the airport uses a pallet truck to transport pallets or containers to cooperate with the loader to load and unload the aircraft. It is composed of a frame, a walking wheel and a traction frame. The frame is equipped with rollers to facilitate the movement of the pallet. The lower end of the frame is provided with a walking wheel. The front end is equipped with a steering traction frame, which has the advantages of simple structure and low cost. The disadvantage is that the pallet or container can only be translated on the frame by rollers, and cannot be rotated on the frame of the pallet truck. The rotation of the pallet or container must be on the platform truck. The operation is cumbersome, which prolongs the loading and unloading time of the goods and reduces the work efficiency
