Our LIBUS grooved winch drums are all custom - made, crafted from carbon steel, stainless steel, or aluminum. They handle rope lengths from 10 to 1000 meters and rope diameters between 2 and 80 millimeters. The unique LIBUS groove design prevents rope tangling even after multiple layers of winding, reducing steel wire waste and enhancing operational efficiency. For old drums or when changing rope diameters, our grooved bushings fit smoothly, eliminating the need for full drum replacement. These drums are widely applied in oil and gas projects, wind power setups, hydropower hoist，construction tower cranes, port cranes, and other winch - using scenarios.

1. It has specifically groove to make wire rope spooling orderly and uniform strength on every layer.
2. It can be calculated the exact forces that the rope imposed on the drum.
3. The spooling is totally under control,which prevents lower layers being crushed or pinched by upper layers
4. With the groove,the continuous groove in the drum is parallel to the flange except for two crossover points on each Revelution where the groove moves across the drum half a pitch to give a pull pitch of movement for each pitch.
Double folding rope groove makes the wire rope winding smooth, load evenly distributed between each layer, practice has proved that this technology greatly prolongs the service life of wire rope, data shows that can prolong the life of wire rope more than 500%, reduce wire rope damage, improve safety, and reduce the mechanical equipment for rope replacement downtime.
