Customized Large Groove Winch Drum /Winch Hoisting Used On Marine
deck
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.
Techinical parameters:
| No: | Wire diameter (mm): | direction | Main drum diameter(mm) | Main drum length(mm) | application |
| 1 | 13 | Lefthand | 430 | 763 | The oil workover rig |
| 2 | 18 | Lefthand | 623 | 1144 | The oil workover rig ,Logging Winch drum |
| 3 | 22 26 | Lefthand,Righthand | 730 | 1120 | Drilling Rig Winch/ drawworks |
| 4 | 18 22 32 | Lefthand,Righthand | 670 | 1240 | hoist |
| 5 | 28 32 36 | Lefthand,Righthand | 560 | 630 | Rotating Drilling Rig winch,Lifting equipment |
| 6 | 26 45 | Lefthand,Righthand | 760 1146 | 1970 1765 | Offshore Crane,Marine crane ,wharf crane |
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.
