Product Description
Product 
Double Girder Overhead Crane with Electromagnet is a specialized crane for lifting and moving steel products, steel plates and steel pipes. This crane is 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).
Features
1
Three kind entrances to the cab: end, side and top entrances;
2
The rotating part of hook must be locked by screws during electromagnetic plate working;
3
Its lifting capacity includes the weight of electromagnetic part, and the weight of whole crane does not include the weight of electromagnetic chuck and its components; 
4
Box-typed girder structure is welded in high strength by robots;
5
Wheels, winding drums, gears and couplings are manufactured by CNC with best quality;
6
Heavy-duty slip ring motor from Wuxi NGP, the best quality in China;
