Complete Quality Alloy Steel Wire Rope Lebus Grooved Winch Drum
Structure:
it is composed of two parallel grooves and two crossed grooves in
every circle of the winch drum.
The advantages of multilayer winding:
When the wire rope need to wind many layers, the lebus 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 lebus 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.
The advantages of single layer winding:
According to your condition, since there is not pressure rope
device, your movement is rely on the friction force between drum
and wire rope. In order to prevent the wire rope from slipping, it
is necessary to increase friction between the drum and wire rope.
Compared to the spiral groove, the lebus groove have two
parallel-line segment and two crossed -line segment, so the lebus
have a larger friction, which could prevent wire rope from
slipping.
Service conditions of Lebus groove
1. The flanges of drum shall be perpendicular to drum wall at any
conditions,even under the load.
2. The rope must be kept under tension in the process of spooling
so that the rope will be crushed against groove wall. When spooling
can not meet this condition,a press roller shall be used.It is
generally recommended that the tension of the rope should be at
least 2% breaking tension or 10% working load.
3. The fleet angle range should generally never be more than 1.5
degrees and not less than 0.25 degrees.
4. When the wire rope released from the drum goes around the
sheave,the center of sheave should be over the center of drum.
5. The rope must be kept round,not loose,even under the maximum
load.
6. The rope must be anti-rotation structure.
Pls measure the change of rope diameter under different load
