Right-hand 60° Lebus Sleeve Plug Welding 99.6mm Groove-pitch

Product Introduction:

Sleeves are used to prevent damage to the drum. Lebus Sleeve is usually cheaper to replace a worn out sleeve instead of replacing or repairing the complete drum assembly. That is why Lebus Sleeve has become so popular. The LeBus Grooving System involves a product made specifically for use on any or all types of hoisting drums requiring the use of wire rope or electro-mechanical cable.

Technical Parameters:

Advantages of Lebus Sleeves:

• Safer Winding

Equal coil quantity per layer stops cable cutting and abrasion, preventing early rope damage, a unique advantage exclusive to the Lebus system.

• Longer Rope Lifespan

Stepped layered winding eliminates inter-rope friction, greatly extending wire rope service life.

•  Faster Working Speed

No extra manual or mechanical rope guiding needed, enabling faster drum operation.

• Easy Retrofitting

The sleeve fits smooth drums both in new production and on-site equipment upgrade.

• Lower Operating Cost

High-priced cables last far longer, cutting frequent replacement costs. Most drilling users recover the sleeve cost through rope expense savings alone, with outstanding stability and performance recognized widely.

Structure of Lebus Sleeve:

1.A Lebus sleeve is a split‑type grooved outer cover fitted onto a smooth winch drum.
2. It is normally made of two half‑arc segments and fixed by bolts around the drum surface.
3. Its outer surface is machined with special broken‑line grooves, consisting of straight segments and inclined transition segments.
4. The straight grooves support steady rope seating while the inclined sections guide layer‑to‑layer rope crossover.
5. This controlled‑groove structure arranges multi‑layer wire rope neatly and prevents rope biting, chaos and premature wear.
