Mooring winches for ships are mechanical devices used to secure vessels to docks or other stationary structures by handling ropes or cables. They provide controlled tension and release during mooring operations, ensuring stability and safety. These winches are essential for efficient and secure docking in various maritime conditions.

Size: Typically ranges from 200 mm to 1000 mm drum diameter, depending on vessel size.

Grade: Commonly complies with ISO 9001, ABS, DNV, or Lloyd's Register standards.

Viscosity: Hydraulic systems use ISO VG 32 or VG 46 hydraulic oil.

Buoyancy: Not applicable; designed for deck-mounted use.

Material: Drum and frame usually made of high-tensile steel (ASTM A36 or equivalent).

Load Capacity: Ranges from 5 tons to 100 tons, depending on application.

Braking System: Dynamic braking with fail-safe mechanical brakes.

Power Source: Electric, hydraulic, or pneumatic drive systems.

Line Speed: Adjustable, typically 10-30 meters per minute.

Rope/Wire Compatibility: Compatible with synthetic ropes or steel wires (6x36 or 8x36 class).

Corrosion Resistance: Galvanized or stainless steel components for marine environments.

Control System: Manual, remote, or automated tension control.
