Our company, located in Shijiazhuang City, Hebei Province, China, specializes in manufacturing Lebus grooved double drums used in shipyards and marine winch systems. These high-precision components are essential for safe and efficient cable handling in shipbuilding, offshore lifting, and marine engineering applications.
Designed for durability and performance, our double-drum systems ensure smooth wire rope spooling, reduced wear, and excellent load distribution — meeting the demanding standards of shipyard operations worldwide.
The Lebus grooved double drum consists of two interconnected drums, each with double-helical Lebus grooves. These grooves guide the wire rope precisely across multiple layers, preventing overlap and maintaining consistent tension during operation.
This design is ideal for marine winches, mooring systems, and towing equipment, where heavy loads and constant motion require maximum reliability.
Precise Rope Spooling
The patented Lebus groove pattern ensures even rope winding, layer by layer, avoiding rope stacking and improving safety.
Double Drum Design
Enables dual-line operations or synchronized winding for complex marine lifting tasks.
High-Strength Construction
Built from carbon steel or alloy steel (Q345B, 42CrMo) to handle extreme load capacities common in shipyard and offshore use.
Corrosion-Resistant Coating
Protected with epoxy marine paint, hot-dip galvanizing, or special anti-rust coating for long-term seawater resistance.
Custom Engineering
Drum size, groove dimensions, and rope capacity can be fully customized according to the shipyard’s winch specifications.
Our Lebus grooved double drums are widely used in:
Shipyard lifting and towing systems
Marine deck winches
Mooring and anchor handling winches
Offshore oil and gas platforms
Dockyard cranes and lifting units
The double-drum structure allows simultaneous control of multiple cables, improving operational efficiency and safety in marine construction and maintenance tasks.
