The crane is an indispensable auxiliary machine for some large industry production, and the reliable connection between the reel and the starting power of the sling, the core part of operation and safety, is the most direct guarantee for the working quality and safety performance of the crane. Therefore, the reliability requirements of this coupling are very strict. It not only bears radial load, but also transmits large torque. Meanwhile, it shall compensate the deviation of installation position.

WZL and DC series drum couplings manufactured by Rokee according to the national standards are strictly in compliance with the quality control system requirements. We optimize technological process of products and upgrade the material design of key parts to achieve more reliable quality.

Relying on Rokee's quality, our products are now used in metallurgy, mine, water conservancy and port wharf and many other occasions.
