Split-sleeve consists of a pair of outer shells that are bolted or welded onto a smooth drum. We can manufacture spiral groove and lebus groove.
The split-sleeve depends on the drum’s size,wire rope diameter and length.
Our factory has more than 2000 sets of advanced equipment such as casting, forging, gear processing, sheet metal stamping, riveting, heat treatment and mechanical processing. In recent years, the Germany CW1000 machining center, CNC four axis, five axis linkage machining center, CNC punch, large CNC hobbing gear grinding machine, large CNC floor boring and milling machine, Vacuum electron beam welding, CNC welding robot and 80 roll machine

Company introduction
Our company early introduction of advanced technology at home and abroad, after years of research and development and improvement, in the hoisting machinery multi-layer wire rope row rope field has made a major breakthrough,
In 2010, the company obtained the production patent of double folding rope groove drum, and founded its own brand - LBS. At present, the company has formed a mature and stable, serializedproduct production mode.
