Capstan Motors - Deck Machinery and Hull Equipment
Capstan motors provide reversible rotary power for marine capstans used to handle mooring lines, warping duties and deck equipment. They are commonly marine-duty electric or hydraulic motors selected for high starting torque, frequent starts, harsh weather exposure and vessel electrical or hydraulic systems.
ProShipWorks provides end-to-end support to source and supply Capstan Motors 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 | Marine electric motors are generally designed and tested to applicable IEC 60034 requirements. Shipboard installation may also be subject to IEC 60092-301 and vessel flag-state rules. Capstan machinery requirements may reference ISO 7825. Exact compliance depends on motor configuration and supplied documentation. |
|---|---|
| Class Approval | Marine motor series or individual units may be supplied with type approval or product certificates from DNV, ABS, Lloyd's Register, Bureau Veritas, RINA or ClassNK. Approval is manufacturer-, model- and vessel-specific and must be verified from the certificate supplied with the motor. |
Installation, Maintenance & Safety Information
| Installation Notes | Match rated power, torque, speed, duty cycle, voltage, frequency, mounting arrangement and hazardous-area requirements to the capstan. Align the motor and gearbox accurately, secure the foundation, verify rotation, fit guards, and use approved marine cable glands, earthing and overload protection. |
|---|---|
| Maintenance Tips | Inspect terminals, insulation, bearings, brake, coupling and mounting bolts regularly. Keep cooling passages clear, control corrosion, lubricate bearings as specified, test space heaters, and monitor vibration, temperature and winding insulation resistance. |
| Safety Notes | Isolate and lock out electrical or hydraulic power before servicing. Keep personnel clear of rotating parts and tensioned lines, fit guards, verify emergency stops and brake operation, and never exceed the capstan or motor rated load and duty cycle. |
