Carbon Steel Wire Rope Hoisting Single Model Lebus Grooved Winch
Drum
Grooved Winch Drum Introduction
The device comprises a slotted drum body, a rope groove is
processed on the slotted drum body, a primary climbing groove and a
secondary climbing groove are opened on the slotted drum body, and
the climbing angle of the primary climbing groove is from 0 ° to 72
°, The climbing end point of the primary climbing groove is the
starting point of the secondary climbing groove. The utility model
realizes the avoidance of rope disorder and rope biting of the
steel wire rope caused by the welding error, simplifies the
processing technology and saves the processing cost. The utility
model overcomes the deformation of the existing drum body processed
after assembly and welding, resulting in the asymmetry of the
centers at both ends of the drum body, At the same time, there are
some deficiencies that can not guarantee the thread pitch accuracy
and thread surface strength
Service conditions of Lebus groove
1. The flanges of drum shall be perpendicular to drum wall at any
conditions,even under the load.
2. The rope must be kept under tension in the process of spooling
so that the rope will be crushed against groove wall. When spooling
can not meet this condition,a press roller shall be used.It is
generally recommended that the tension of the rope should be at
least 2% breaking tension or 10% working load.
3. The fleet angle range should generally never be more than 1.5
degrees and not less than 0.25 degrees.
4. When the wire rope released from the drum goes around the
sheave,the center of sheave should be over the center of drum.
5. The rope must be kept round,not loose,even under the maximum
load.
6. The rope must be anti-rotation structure.
7. Pls measure the change of rope diameter under different load.
Advance
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

Grooved Winch Drum Structure
Groove Drum Composition: Drum core, Flanges, Shaft, Etc
Processing: Rope drums with grooves cut directly into them.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.
