Marine LBS Grooved Winch with Large Drum Diameter & Length for Multilayer Winding

LBS Structure:
it is composed of two parallel grooves and two crossed grooves in every circle of the winch drum.

The LBS groove is cut directly into the body of the drum, according to customers’ requirements, the flanges are either welded or screw-bolted. groove geometry is determined by rope construction, diameter and length, and by application. the drum has the required mounting dimensions for the actual operating conditions.


Required Parameters if you choose to customize:
1. Wire rope diameter or cable diameter(mm)
2. Inner diameter of plain dru(mm)
3. Outer diameter of grooved drum(mm)
4. Width between the flanges L(mm)
5. Rope capacity(m)
6. Material:
7. Rotation direction:left or right?

The advantages of multilayer winding:

When the wire rope need to wind many layers, the LBS groove can fix the crossover point of the upper rope and the lower rope through crossed groove, which could control the crossover point and make it finished in the crossed groove.

In the parallel groove,the upper wire rope can falls into the groove formed by two lower rope. It can form a stable structure between the upper wire rope and the lower wire rope. When the wire rope return to another sides,

Both ends’ bead flange can guide wire rope to climb smoothly and return. This structure make our LBS groove realize multi-layer winding and avoid teh messy rope. However, the ordinary spiral groove only make the first layer smoothly winding, but it can not guide the second layer convolve smoothly back, which is especially easy to cause messy rope problems.
