It is composed of two parallel grooves and two crossed grooves in
each 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
