@@Materrial Handling Machined Steel Crane Drum, Gantry Crane Electric Motor Cable Reel Drum

Crane drum is the component to wind wire rope in the lifting mechanism.

Crane drum consists of drum shaft, flange type annular gear,drum hub,bearings,bearing pedestal.

When one end of drum is equipped with the switch of rotary type position limitation limiter,it must ensure to make drum shaft and rising limit switch rotate synchronously.
