Drum Couplings

The Crane Drum Coupling is an important part in the transmission system of crane equipment. It connects the power input shaft of the reducer with the drum, transmits torque and restricts the axial movement of the drum at the same time. It also has mechanical or electronic wear alarm, and is one of the core parts of the drum crane mechanism.

The RWC ball and drum gear drum coupling is a drum coupling developed by Rokee with a more reliable structure, higher compensation ability and higher safety factor. The outer sleeve adopts a spherical drum tooth design, which has low requirements for shafting installation accuracy, large transmission torque, strong overload capacity and can withstand great radial load. The connection size is the same as that of DC series, but the bearing capacity is increased by more than 30%. The innovative spherical sealing technology makes this type of product maintain excellent lubrication and greatly improve its service life.
