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,

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.
