Crane Drum Coupling

The drum coupling is the crane drum coupling. The internal sphere gear sleeve is assembled with the external drum perfectly. Relying on the specially designed key, the external sphere shaft sleeve forms the entirety with gear sleeve perfectly. It will promote the reliable connection of reducer shaft and drum and it is the most ideal product in the market home and abroad at present.

RWC series drum coupling is a type of high-performance drum coupling developed by us and mainly applied for port lifting and large mechanical lifting. In comparison with international DC series products, it has identical outline and connection size, but its interior design is more thorough and steady. The hook face of gear is optimized and the large pressure angle design is applied. A patented mechanism is used for the sealing. One-time filling of lubricating grease is basically free from maintenance, solving maintenance difficulty at heights. In addition, an electronic warning device is set. When the wear life reaches the safe position, the weak current connection will trigger the alarm immediately. It’s a good choice for you!

RWC Drum Coupling

Ball and Drum Gear

The 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.

DQ/WZL Drum Coupling

Ball Dumpling

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.
