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.
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 grooved
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

Product structure:
Integral rope groove drum: rope drums with grooves cut directly into them (with or without bolted or welded flanges, as required).Winch 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.
Product advantage:
Compared with the general non grooved (smooth) drum and spiral grooved drum, the Grooved Steel Drum Sleeves has obvious advantages in the neat winding of multi-layer steel wire rope. Lbs double fold rope groove makes the winding of steel wire rope more smooth and the load between layers is evenly distributed, reduces the irregular, disorderly winding and rope biting in the process of steel wire rope arrangement, reduces the damage of steel wire rope, prolongs the service life of steel wire rope, improves the safety of equipment operation, and avoids the shutdown time of mechanical equipment due to disorderly rope replacement.
