Cable multilayer winding main drum used for truck cranes
The Lebus cable groove winch developed by our company solves the
following problems:
1. The steel wire rope can be wrapped in multiple layers without
disorderly rope;
2. Wire rope winding speed is not restricted;
3. The load is evenly distributed between the wire ropes;
4. Under the condition of load, no rope biting or rope skipping
between the wire ropes;
5. Reduce the damage of wire rope and improve the safety;
6. Reduce the downtime of wire rope replacement, greatly improve
the work efficiency.
After using a large number of data sheet: prolong the service life
of wire rope more than 500%.
range of application
Widely used in offshore platforms, petroleum machinery, water
conservancy machinery, port machinery, large engineering machinery
lifting equipment.
types of structure
Winch drum with groove mainly has the following three types of
structure
1, splicing type. In this structure, the rope groove body is first
made into 4 pieces of tile, and then the 4 pieces of tile groove
and light drum body are spliced and welded together
2, integral, is the rope groove is directly located on the drum
body, rope groove and drum body as one.
3. Plug welding type, make the rope groove into a cylinder body,
and then cut it into 2 pieces of tiles, and plug welding on the
drum body.

The structural point of the LEBUS groove
The drum rope groove of drill winch adopts the form of double
broken line structure, and its characteristics are diagonal rope
groove and straight rope groove appear alternately, thus forming
two diagonal rope groove area and two straight rope groove area on
the surface of the drum. The so-called inclined rope groove refers
to the rope groove that intersects diagonally with the drum bus,
and the straight rope groove refers to the rope groove that
intersects directly with the drum bus or is parallel to the flange.
Diagonal strong groove controls the pitch of rope groove, which
accounts for a small proportion in a circle of rope groove. Its
structure point can effectively alleviate the problems of extrusion
deformation, mutual friction and early wear of wire rope during
loading.
The processing and production of the lebus groove can be directly
processed on the drum as a whole, and can also be made into a set
with the rope groove, and made into a split type, wrapped in the
smooth drum when installed, connected with the drum through bolts
or welding. The material of folding rope groove barrel can be
divided into carbon steel, stainless steel, alloy steel, aluminum
or glass fiber, etc. The barrel can be made by sheet rolling or
casting.
