Cantilever crane working strength is light, the crane consists of column, slewing arm slewing drive device and electric hoist, the lower end of the column is fixed on the concrete foundation through the foot bolt, by the cycloid reduction device to drive the cantilever slewing, electric hoist in the cantilever I-beam for left and right linear operation, and lifting heavy objects.

The crane jib is a hollow steel structure, with light self-weight, large span, large lifting capacity, economic and durable. Built-in walking mechanism, using special engineering plastic wheels with rolling bearings, low friction, light walking; small structure size, especially conducive to improve the hook stroke.
