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,
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,
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.

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. Please measure the change of rope diameter under different load.
