The electromagnetic bridge crane is equipped with detachable electromagnetic disks and is particularly suitable for heavy loading, unloading and handling of magnetic ferrous metal products and materials (such as steel ingots, section steel, pig iron blocks) in fixed spans indoors or outdoors in metallurgical plants. It is also often used in mechanical factories and warehouses to handle steel materials, iron blocks, scrap iron, scrap steel, iron filings and other materials.

Electromagnetic bridge crane belongs to heavy class (A6) work system, crane includes electric disk weight. This machine is composed of five parts: box-shaped bridge frame, large vehicle running mechanism, small vehicle, electrical equipment and electromagnetic disk. All mechanisms are operated from the control room. When used outdoors, it is equipped with rainproof devices.

The basic structure of the electromagnetic bridge crane for lifting equipment is the same as that of the hook bridge crane. The difference is that a DC lifting electromagnet (also known as an electromagnetic suction cup) is hung on the hook, which is used to lift ferromagnetic ferrous metals and their products. Usually, the AC power is converted into DC power through an electric generator set set on the bridge frame walkway or a thyristor DC box installed in the driver's cab. Then, the DC power is delivered to the lifting electromagnet via a flexible cable through a special cable drum set on the trolley frame.
