High Qulaity Widely Used Crane Drum

Part 1: Description
Wire rope drums are engineered and manufactured to meet the most challenging operational and safety constraints for industrial crane application. Our wire rope drums can be found on typically every type of crane in a number of industrial environments.
·  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.
