As the cornerstone of the infrastructure industry and the foundation of heavy industry, magnets and magnetic components are also used in the steel industry. Because of the large size of steel, it is very laborious and uneconomical to move it by hand. Therefore, in steel mills, a traveling crane is installed, and the crane is equipped with our magnetic lifting device so that the huge steel plates can be easily "catch" and transported firmly according to the set trajectory.
