overview of the Lebus Grooved
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, it is named "folding
rope groove" too.
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
Advantage Of The LBS Grroved
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%.
LBS rope groove makes the load evenly distributed between layers,
and the practice proves that it greatly prolongs the life of wire
rope. In fact, the test surface can extend wire rope life by more
than 500%. Reducing wire rope damage increases safety and reduces
machine downtime.
Disadvantage Of The LBS Grroved
The disadvantage of LBS rope groove drum is that it is more
complex, so it is a little more expensive than the spiral rope
groove drum. However, this additional cost is quickly compensated
for by the savings in wire rope, which is expensive and takes up
production time to replace.
Conditions of LBS grroved
LBS rope groove drum also requires certain operating conditions.
The most important of these conditions is the deflection Angle of
the wire rope, which is the Angle between the wire rope from the
reel to the first fixed pulley. Generally speaking, this deflection
Angle should not be greater than 1.5° and should not be less than
0.5°. There are some slight differences (about a 0.25° variation),
but it is good to remember this general statistic. The optimal
deflection Angle also depends on the load, cable structure and
lifting speed. This deflection Angle indicates that for every 10m
from the drum to the pulley, the distance between the wire rope and
the midpoint of the drum should not be greater than 260mm (520mm
between the two flanges). 9 Q2 ` 2 L! For LBS groove reels, if the
deflection Angle exceeds the recommended range, a special rope
called Angle compensator can be used to relax and be damaged by
extruding or twisting of the outer wire rope onto the groove
