Windlass Brakes - Deck Machinery and Hull Equipment
Windlass brakes control and hold the anchor chain and wildcat on marine anchor windlasses. They are normally mechanical band or disc assemblies operated manually, hydraulically, or pneumatically and matched to the windlass and chain load.
ProShipWorks provides end-to-end support to source and supply Windlass Brakes 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 | Common requirements include ISO 4568 for sea-going vessel windlasses and IACS UR A3 for anchor windlass design and testing. Materials, welding, machinery guarding, and hydraulic components may also be subject to applicable flag-state and class rules. |
|---|---|
| Class Approval | Approval may be provided as part of the complete windlass system by DNV, ABS, Lloyd's Register, Bureau Veritas, ClassNK, RINA, or other vessel class societies. Acceptance depends on design calculations, holding-load tests, materials, and vessel-specific class requirements. |
Installation, Maintenance & Safety Information
| Installation Notes | Use the OEM brake assembly, lining grade, fasteners, and clearances for the windlass model. Align the band or caliper evenly with the drum or disc, verify actuator travel, and conduct operational and holding-load tests after installation. |
|---|---|
| Maintenance Tips | Inspect linings for wear, glazing, oil contamination, cracking, and uneven contact. Check pins, springs, linkages, handwheels, hydraulic seals, fasteners, and drum or disc condition. Adjust clearances only to OEM limits and renew contaminated linings. |
| Safety Notes | Secure the anchor with the chain stopper and isolate windlass power before maintenance. Never rely solely on the brake while personnel work near the chain path. Keep clear of snap-back and pinch zones, and do not exceed the approved holding load. |
