>winding drum is the component to wind wire rope in the lifting mechanism. Rolling drum consists of drum shaft,Â
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.
->Drum material generally adopts cast iron. For special use, drum can be weld with cast steel or steel plate.
