characteristic: QA type universal bridge crane, overhead crane, traveling crane, with detachable electromagnetic disc, especially suitable for heavy loading and unloading and handling of magnetic black metal products and materials between fixed spans indoors or outdoors in metallurgical factories. It is also commonly used in machinery factories and warehouses to transport materials such as steel and iron filings.
This machine consists of five parts: box type bridge, large vehicle operating mechanism, small vehicle, grab bucket, and electrical equipment. All mechanisms are operated in the control room. Rainproof equipment is required for outdoor use.

A machine that uses electromagnetic principles to transport steel items. The main component of an electromagnetic crane is the magnet. By connecting the current, the electromagnet firmly attracts the steel object and lifts it to the designated location. Cut off the current, the magnetism disappears, and the steel object is put down. Electromagnetic cranes are very convenient to use, but they must have current to be used, and can be applied in waste steel recycling departments and steelmaking workshops.

The device that uses electromagnets to transport steel materials is called an electromagnetic crane. Electromagnetic cranes can generate strong magnetic field forces, and can easily collect and transport iron sheets, wires, nails, scrap iron, and other various iron materials weighing tens of tons without packing, bundling, or bundling. This not only saves effort in operation, but also simplifies the work. Steel materials and machines packed in wooden boxes can be transported in the same way. When the crane is working, as long as the current in the electromagnetic coil keeps flowing, the lifted heavy object will not fall, and the invisible magnetic force is more reliable than a sturdy chain. If the power is cut off for some reason, it can cause accidents. Therefore, some electromagnetic cranes are equipped with steel claws. After the heavy objects to be transported are lifted, the sturdy steel claws automatically fall down and tightly grip them. Cranes cannot transport hot iron blocks because high-temperature steel cannot be magnetized. A large electromagnetic crane can lift nearly a hundred tons of heavy objects at once. The diameter of the electromagnet in the picture is about 1.5 meters, which can lift an object of 16 tons.

On February 21, 2008, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China issued the "Regulations on Safety and Technical Supervision of Lifting Machinery - Bridge Cranes". Article 66 states that the lifting electromagnet of an electromagnetic crane should be powered by a dedicated circuit. When the electromagnetic crane loses power during operation and the items it lifts may cause harm due to falling, it must be able to ensure power supply to the electromagnetic suction cup.
