Q355B 4-Channel Lebus Drum Corrosion Resistant Winch Drum For Ø6 Stainless Steel Wire Rope

1.Product Description

Model LBSS-4CH-DN6-D284-L326 is an integrated 4-channel LEBUS drum. It features four isolated rope groove zones with right-hand 50° double crossover LEBUS grooves, engineered for Ø6 stainless steel wire rope. It enables synchronous multi-layer winding and payout of four wire ropes without mutual interference. Manufactured by one-piece CNC machining, this drum delivers high coaxial accuracy. Zinc-rich primer coating is applied for rust and corrosion protection, making it suitable for synchronous multi-rope pulling and instrument retrieval in marine and humid corrosive environments. It is a core component for multi-rope synchronous winches.

3.Advantages

1. Four isolated rope zones. Four wire ropes wind separately without friction or cross-interference, ensuring high precision for synchronous rope operation.
2. 50° right-hand crossover LEBUS groove design realizes smooth layer transition. Effectively prevents rope nesting, crushing and abrasion to protect thin stainless steel wire rope.
3. One-piece CNC machining guarantees superior coaxiality and low runout, stable rotation during precise pulling.
4. Zinc-rich primer coating provides reliable corrosion resistance, ideal for marine and high-humidity working conditions.
5. Flange bolt connection structure, easy positioning, firm installation and convenient maintenance.
6. R3.3 groove profile perfectly fits Ø6 wire rope, evenly distributes load and reduces local stress concentration to extend rope service life.

4.Application

It is compatible with small hydraulic winches, electric synchronous pulling winches and compact logging winches. Widely used for underwater instrument deployment & recovery, marine exploration, vessel auxiliary traction, automated hoisting and other corrosion-resistant scenarios requiring multi-rope synchronous winding.
