[0002] In the modern steel industry, the production of ultra-thin steel coils requires extremely high precision and stability of the equipment. Among them, the roller is an important part of the rolling mill, which is cylindrical and. At present, within steel enterprises, the rollers are generally transported by lifting belts or wire ropes, such as: CN208120549U, a continuous roller lifting device.
