Electromagnetic bridge overhead cranes are a specialized crane for lifting and moving steel products, steel plates and steel pipes. Electromagnetic bridge overhead cranes are constituted by girder, traveling mechanisms, lifting trolley, electric parts and electromagnet spreader. The electromagnetic suction force of this overhead crane can last 10 minutes after power off. And the shape of electromagnet spreader could be customized bases on the shape of materials to be lifted.
There are 2 types of electromagnet spreader: electromagnetic chuck and electromagnetic beam. And electromagnetic beam can also be 2 kinds: non-rotating beam (vertical or parallel to main girder) and rotating beam (Upper beam or hanging beam).
