Mooring winches are devices used to secure ships by controlling the tension in mooring lines during docking or anchoring. Windlasses are specialized winches designed specifically for handling anchor chains and ropes in marine operations. Both are essential for vessel stability and safety during mooring and anchoring procedures.

Mooring Winch and Windlass Key Specifications:

Size: Typically ranges from 12 kW to 350 kW, drum capacities from 500m to 3000m rope length.

Grade: High-tensile steel (ASTM A514 or equivalent), corrosion-resistant coatings.

Viscosity: Hydraulic oil ISO VG 32 to VG 68, depending on operating temperature.

Buoyancy: Not applicable (winches are deck-mounted).

Material: Drum and frame—carbon steel or stainless steel; brake linings—heat-resistant composites.

Mooring Winches Additional Properties:

Size: Drum diameters 400mm to 2000mm, line pull 50 kN to 2000 kN.

Grade: Wire rope typically grade 1960 MPa or higher.

Viscosity: Grease NLGI 2 for bearings and gears.

Buoyancy: N/A (non-floating equipment).

Material: Gears—alloy steel (AGMA 8-10); brakes—fail-safe disc or band type.
