The rail electric transfer cart is an efficient and convenient handling tool. It can be widely used in heavy-load occasions such as factories, warehouses, and ports. It has the advantages of stable operation, efficient handling, and safe operation. The design of the two sets of wheels on the bottom layer enables the rail electric transfer cart to move freely on the vertical and horizontal tracks, and can also carry a large amount of materials, thereby improving the efficiency of logistics. In addition, the hydraulic lifting design of the upper layer of the car body enables the rail electric transfer cart to easily adjust the lifting height to adapt to handling tasks at different heights, greatly improving work efficiency.
