Problems solved by technology

[0003] The shuttle car rack 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 efficiency of goods access in the warehouse, making full use of the warehouse space. About 80% to 85% of the space in the warehouse can be used, suitable for Different types of products can be accessed flexibly in different layers. Compared with drive-in racks and through racks, the structural root is stable and the safety factor is high. And the environment is becoming more and more harsh, and the thickness of the steel plate is getting thicker and thicker. Correspondingly, the technical requirements for the steel plate used for storage equipment are also increasing, and it needs to have sufficient transverse yield strength; in addition, especially for storing some When the goods are corroded, the storage equipment is often broken in a short time due to the corrosion of the steel plate; the storage cost is increased
