Problems solved by technology

The shelf in the storage equipment is a relatively commonly used equipment. The shuttle car shelf is characterized by the fact that the forklift does not need to enter the roadway, which saves time, improves the safety of personnel and goods, and greatly improves the storage and retrieval efficiency of goods in the warehouse. Make full use of the warehouse space. About 80%~85% of the space can be used, which is suitable for different types of products and can be layered and flexibly accessed. Compared with the drive-in frame and the through frame, the structure is stable and the safety factor is high. It can realize first-in-fir
