The main structure of magnetic suspension: Magnetic suspension, also known as "permanent magnet lifting device", is composed of high-performance permanent magnetic materials to form a strong magnetic system. Through the rotation of the handle, the magnetic force of the strong magnetic system is changed to achieve the absorption and release of the workpiece. The magnetic suspension has a lifting ring on the upper part for lifting objects, and a V-shaped groove on the lower part for holding corresponding cylindrical objects.

　　Purpose of permanent magnet crane: it is widely used in the lifting and transportation of steel in warehouses and operation sites, the movement of working machinery, and the up and down movement of machine tool machining parts. It is used in conjunction with cranes and elevators to lift and transport goods. It is suitable for the transportation of all kinds of flat steel, mechanical parts or semi-finished products, and molds. Greatly providing work efficiency and reducing lifting costs. Magnetic suspension has small volume, light self weight, and strong suction force. Unique magnetic circuit design, with almost zero residual magnetism. High safety factor, with a maximum pull-out force of 35 times the rated lifting force. The handle switch is equipped with a safety button, which can be operated with one hand for convenience and safety. The bottom surface of the crane is designed with a "V" groove, which can lift corresponding round steel and steel plates. No electricity, the magnetic force is long-lasting and safe to use. It can be used for outdoor operations and is widely used for lifting and transporting flat mechanical components and steel. It can be widely used in the mold and mechanical manufacturing industry.

　　The permanent magnet lifting equipment of Shanghai Industrial and Commercial Corporation is mainly used in shipyards, riveting and welding factories, steel structure factories, warehouses, workshops, freight yards, and other lifting equipment to hold plate shaped ferromagnetic materials or workpieces. It can be used alone or in combination with multiple sets to transport large and long ferromagnetic material workpieces. Magnetic cranes can replace electromagnets for lifting steel plates in freight yards, steel plate pre-treatment production lines, steel plate cutting lines, and other occasions. Magnetic suspension has the characteristics of lightweight structure, convenient operation, strong suction force, no power consumption, and safety and reliability, which helps to improve the working conditions of loading, unloading, and transportation operations and increase labor productivity. As an efficient, safe, and energy-saving new lifting tool, it has been widely used in industries such as shipbuilding, engineering machinery, and mold manufacturing.
