Double-girder overhead crane includes 4 main components: main bridge, trolley, cart and electrical system. Using wire rope hoist as a lifting mechanism.

Double-girder overhead crane includes 4 main components: main bridge, trolley, cart and electrical system. Using wire rope hoist as a lifting mechanism.
- This product has two form that is single hook and double hook.
- Single hook usually has 5T, 8T, 10T, 16T, 20T, 32T. It also has extra hook for 16T, 20T, 32T.
- Double hook has five commonly used specifications: 2T+2T, 3T+3T, 5T+5T, 8T+8T, 10t+10T.
- Span: 10.5-35.5m.
- Bridge beam includes main beam, end beam, walk lane, conductive frame, cage, driver room, barrier, rail, ladder and other components.
+ Main beam and end beam are connected by bolts. Walk lane sets up on non-conductive side and lasts whole crane's span. Cab has open and close design.
+ Non-conductive side has long walk lane, both its two side are widened for maintenance, replacement of carts and electrical equipment; the middle of walk lane is standard specialization. The other side of the bridge, the conductive frame welded to the main beam cover, for C-type slide transmission system (flexible cable car power supply system).
+ In order to facilitate maintenance of the whole conducive system (safety trolley, collector) whole power supply measured with cage.
+ Driver room has two kinds of type close and open, whole structure was connected with bolts to reduce the welding deformation, field of view is greater than 2800 . Driver room can be configured air conditioning.
- Cart Hoist divides into 3 types: constant speed, ordinary two-speed, frequency control. Indeed, frequency control has good performance, lifting stable and reliable.
