Crane 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.

WZL Drum Coupling
WZL Drum Coupling is a spherical hinged coupling. It has a connecting flange with an inner spherical surface, a spherical semi-coupling sleeve with an outer spherical surface, a special transmission key, an inner and outer limit cover, etc. The internal control generally adopts the splined sleeve design, which transmits torque through a specially designed key bar and can withstand large torque and radial load. The maximum angular displacement compensation can reach 3°, with a life indicator and safe and reliable structure.View More -
DC Drum Coupling
DC Drum Coupling is designed with drum teeth, which is used for connecting the reducer of crane transmission system with the drum. It can bear radial load and transfer large torque, but cannot transfer axial load.View More -
WJ Drum Coupling
WJ Drum Coupling is a spherical roller coupling, which is composed of jacket with connecting flange, spherical roller, semi-coupling, inner and outer cover plate and sealing system, capable of transmitting large torque and bearing radial load.View More -
WJA Drum Coupling
WJA Drum Coupling is a spherical roller coupling, which is composed of jacket with connecting flange, spherical roller, semi-coupling, inner and outer cover plate and sealing system, capable of transmitting large torque and bearing radial load. The connection between the coupling and the output shaft of the reducer adopts an involute spline pair design.View More
