LBS drum is a kind of groove for multi-layer winding of wire rope
introduced from abroad. Because of this rope groove in the drum
Most of the circumferential section is kept parallel to the flange
end face, only in a very small section and the flange end face
intersection, so the rope groove must
However, there is a phenomenon of turning, hence the name "folding
rope groove".
Years of practical use has proved that this kind of drum with
special rope groove structure can well solve the difficulty of
multi-layer winding rope
The double folding cable groove system ensures that the multi-layer
winding wire rope on the drum is completely smoothly drawn into and
rolled out of the drum, and can be
This system is still the most effective and perfect method to
prolong the life of wire rope. Tests have shown that the use with
Wire rope specifications match the rope groove, Lebus drum can
prolong the life of wire rope more than 500%.
Our factory has more than 2000 sets of advanced equipment such as
casting, forging, gear processing, sheet metal stamping, riveting,
heat treatment and mechanical processing. In recent years, the

drum with flange, 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.

Company introduction
Our company early introduction of advanced technology at home and
abroad, after years of research and development and improvement, in
the hoisting machinery multi-layer wire rope row rope field has
made a major breakthrough,
In 2010, the company obtained the production patent of double
folding rope groove drum, and founded its own brand - LBS. At
present, the company has formed a mature and stable,
serializedproduct production mode.
