Windlass Clutches - Deck Machinery and Hull Equipment

A windlass clutch engages or disengages the windlass drive from the wildcat or cable lifter, allowing powered anchor handling and controlled free-fall. Designs commonly use cone, jaw, or multi-plate friction mechanisms with manual, hydraulic, or pneumatic actuation.

ProShipWorks provides end-to-end support to source and supply Windlass Clutches for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval

Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.

Applicable Standards & Certification Windlass assemblies may be designed and tested to ISO 4568 and applicable flag-state, IACS, and classification-society rules. Clutch materials, welding, hydraulic components, and inspection requirements depend on the approved windlass design.
Class Approval Approval is normally project-specific as part of the complete windlass system. Applicable societies may include DNV, ABS, Lloyd's Register, Bureau Veritas, ClassNK, RINA, and CCS when supplied with approved drawings, material certificates, and test records.

Installation, Maintenance & Safety Information

Installation Notes Confirm shaft diameter, keyway or spline, cone angle, rotation, actuator arrangement, and OEM tolerances. Align mating surfaces, apply specified lubricant only where permitted, set operating clearance, and verify full engagement and release before load testing.
Maintenance Tips Inspect friction faces, keys, splines, bearings, pins, and actuator linkages for wear, corrosion, glazing, or oil contamination. Maintain specified clearances, lubricate designated points, test engagement regularly, and replace worn parts with OEM-compatible components.
Safety Notes Isolate electrical and hydraulic power, secure the anchor and chain, and release stored energy before servicing. Keep personnel clear of the cable lifter, chain, and rotating parts. Never engage the clutch at uncontrolled speed or exceed the windlass rated load.
