Our company, based in Shijiazhuang City, Hebei Province, China, specializes in manufacturing large-diameter Lebus grooved sleeves made from high-strength carbon steel. These sleeves are engineered for heavy-duty crane winches and are designed to handle large wire rope diameters under demanding lifting conditions.
We supply Norwegian crane manufacturers and operators with robust, precision-engineered Lebus sleeves that ensure smooth rope spooling, even under maximum load.
The carbon steel Lebus grooved sleeve fits over the winch drum, providing precisely machined double-helical grooves to guide large-diameter ropes. This technology ensures:
Even rope winding across multiple layers
Reduced rope wear and friction
Stable and safe lifting operations
Large-diameter sleeves are especially critical in cranes used in ports, shipyards, offshore platforms, and heavy industry, where both load capacity and rope alignment are essential.
Heavy-Duty Carbon Steel Construction
Provides excellent strength, durability, and resistance to deformation under extreme loads.
Precision Lebus Groove Design
Ensures accurate multi-layer rope spooling, reducing rope fatigue and extending service life.
Large Rope Diameter Capability
Designed to accommodate wire ropes up to 80 mm or more, suitable for heavy-lifting crane applications.
Customizable Dimensions
Sleeve diameter, width, and groove spacing can be tailored to your crane’s winch specifications.
Corrosion Protection
Optional surface treatments, including epoxy coating or hot-dip galvanizing, for marine or outdoor crane applications.
Ease of Maintenance
Split or modular design allows for quick installation and replacement without removing the entire drum.
Our large-diameter Lebus grooved sleeves are widely used in:
Port and shipyard cranes
Offshore oil platform lifting systems
Heavy construction cranes
Industrial hoisting equipment
Marine and offshore winches
They are designed to provide maximum reliability and safety for Norwegian crane operators and industrial lifting systems.
