Hydraulic Winch Drum With Rope Groove LBS Sleeves 20KN 30KN 50KN

Winch grooves sleeves:
LBS groove sleeves can be placed over smooth and ungrooved drums – suitable for modification or replacement of drum. It is usually cheaper to replace a worn out sleeve instead of replacing or repairing the complete drum assembly.
Split-sleeve system structure:
Split-sleeve consists of a pair of outer shells that are bolted or welded onto a smooth drum,The split sleeve is composed of spiral groove and parallel groove, the groove design conforms to the specified wire rope structure, diameter and length.Compared with cordless groove (smooth) drum and helical groove drum.
LBS grooved drum has obvious advantages in multilayer spooling. It can be widely used in the heavy lifting and compact working conditions.

The manner in which wire rope is installed or wound on a drum will, to a large measure, determine the service life of that rope. Improperly wound ropes will cause undue crushing of the rope, doglegs, kinks, excessive abrasion and cutting of the individual wires. Bad spooling also causes uneven application of force and motion. This results in fast fatiguing of the line from the end attachment to the drum.

advantage:

1. Each one circle layer of the grooved drum has two parallel groove section and two groove section

2. Make wire rope spooling more smooth and uniform distribution of load between each layer

3. Prevent cross &mess in rope spooling working happening

4. Lower the rope damage, extend the rope life
