Hot Dip Galvanized Alloy Steel Tower Crane Electric Winch LBS
Grooved Winch Drum
Tower crane winch:
Tower crane is referred to as tower crane, also known as tower
crane, originated in Western Europe. A rotating crane with arms
mounted on top of a towering tower. Large working space is mainly
used for vertical and horizontal conveying of materials and
installation of building components in building construction. It is
composed of metal structure, working mechanism and electrical
system. The metal structure includes tower body, boom and base. The
working mechanism has four parts: lifting, luffing, turning and
walking. Electrical system includes motor, controller, power
distribution cabinet, connecting circuit, signal and lighting
device, etc

Advantages :
LEBUS drum has a special key, is designed at the bottom of the reel
end flange (end insert) and extension pieces, they guide the wire
rope from the first layer to the second layer smoothly.
The lebus groove makes the load evenly distributed between layers,
and the practice proves that the service life of the wire rope is
greatly prolonged. In fact, the test surface can extend wire rope
life by more than 500%. Reducing wire rope damage increases safety
and reduces machine downtime.
Processing type :
Lebus grooved drum
The groove is cut directly into the body of the drum.(according to
customer‘s requirements.
The flanges are either welded or screw-bolted.)
Split-lebus grooved sleeves (shell )
The whole lebus grooved drum is divided into the upper and lower
parts,which we call them lebus split-sleeves. The sleeves are
available a smooth drum or helical drums.

Overview:
Lebus drum is a kind of groove form suitable for multi-layer
winding of wire rope introduced from abroad. Because this kind of
rope groove is kept parallel with the flange end face in most
sections of the drum circumferential direction, and only intersects
with the flange end face in a very small section, the rope groove
must be turned, hence the name "folding rope groove".
Years of practical use show that this kind of special rope groove
structure of the drum, can well solve the problem of wire rope
multi-layer winding rope about double folded cord slot system, to
ensure that the multilayer on the drum winding rope fully involved
in and roll out the reel smoothly, and can greatly prolong the
service life of wire rope, the system is still the most effective
method and the most perfect. Tests have shown that the Lebus drum
can prolong the life of the wire rope by more than 500% with the
rope groove matching the specifications of the wire rope.
