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
