1. Split sleeves can be placed over smooth and ungrooved drums – suitable for modification or replacement of drum.
2. Split-sleeve system consists of a pair of outer shells that are bolted or welded onto a smooth drum to provide a grooving pattern.
3. The split sleeve is composed of spiral groove and parallel groove.
4. The groove design conforms to the specified wire rope structure, diameter and length.
1. The petroleum industry: oil drilling rig, petroleum tractor hoist, petroleum workover rig, trailermounted pumping unit winch , etc
2. Crane machinery: the bridge lifting machine, tower crane
3. The hoist: building wipe wall machine, winding machine
4. Engineering machinery: tower crane, piling machine
5. Marine machinery: offshore petroleum crane winch, drawworks and hoist
LBS groove can solve the rope inter-twist problem and it can extend the rope and winch life especailly in the duty working condition its low noise ,even distribution, to make the work more effeciency.
