5–250 kN Electric Hydraulic Mooring Capstan | Continuous Rope Pulling for Ship

Product Specification

5–250 kN Electric Hydraulic Mooring Capstan | Continuous Rope Pulling for Ship Mooring

Product Overview

The 5–250kN electric hydraulic mooring capstan is a deck-mounted rope handling machine used for controlled line pulling during ship mooring, shifting, harbor operation, and auxiliary deck handling. It uses a warping head to generate frictional pulling force on the rope and is normally selected when the vessel needs continuous rope movement without drum storage.

This product is supplied through long-term qualified hydraulic deck machinery partners, which helps support stable pricing, model selection, and project documentation. Final selection should be confirmed together with working load, rope diameter, warping head size, speed, duty cycle, deck foundation, hydraulic power unit arrangement, control station, emergency stop requirement, and classification society inspection scope.

Quick Specifications

• Product type: electric hydraulic mooring capstan → continuous pulling and warping equipment for ship deck rope handling.
• Supply position: supplied through qualified long-term partner factories → suitable for cost-sensitive projects that still require marine documentation and technical coordination.
• Working load range: 5–250 kN → covers small auxiliary capstans and higher-capacity ship deck mooring applications.
• Speed range: 9–18 m/min → affects rope handling efficiency, operator control, and hydraulic power selection.
• Rope diameter range: 11–46 mm → selected together with rope material, warping head diameter, and required number of rope turns.
• Warping head diameter: 250–700 mm → matching the rope size and contact condition helps improve grip and reduce local rope wear.
• Drive and control: electric hydraulic drive with lever or proportional control → supports high starting torque and smoother speed regulation than simple mechanical operation.
• Mounting form: vertical or horizontal deck-mounted arrangement → chosen according to deck layout, rope lead direction, foundation space, and operator position.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm the function: mooring line handling, auxiliary warping, harbor operation, or project-specific towing line assistance. A capstan is not a drum storage winch.

Step 2: Confirm working load, rope diameter, rope material, expected number of turns on the warping head, and whether the rope is dry, wet, synthetic, or wire rope.

Step 3: Confirm speed range, duty cycle, operating frequency, starting load, overload protection, and whether proportional speed control is required.

Step 4: Confirm vertical or horizontal mounting, deck foundation size, rope lead direction, operator position, safe clearance, and access for maintenance.

Step 5: Confirm hydraulic arrangement: motor, reducer, hydraulic pump, oil tank, cooling, piping route, valve block, pressure gauge, filter, and electric motor power supply.

Step 6: Confirm control and safety scope: local control, remote control, emergency stop, brake or holding function if required, protection cover, and class witness inspection.

Step 7: Provide quantity, vessel type, installation drawing, rope specification, power supply, classification society requirement, delivery destination, and required delivery time.

Hydraulic Drive, Operation & Engineering Advantages

• The capstan provides continuous rope pulling without storing the rope on a drum, which is useful for repeated line adjustment, short-distance warping, and auxiliary mooring work.
• Electric hydraulic drive gives stable torque output and can be configured for smooth start, speed adjustment, and controlled rope movement when proportional control is specified.
• The warping head should be selected together with rope diameter, rope material, contact condition, and expected number of turns so that grip and rope wear are kept within the project requirement.
• Vertical or horizontal mounting allows the equipment to be adapted to different deck layouts, rope lead directions, and operator positions.
• The hydraulic power unit arrangement should consider oil tank capacity, cooling, filtration, pressure setting, piping route, leakage protection, and maintenance access.
• Deck foundation, base frame stiffness, and local reinforcement should be checked by the shipyard or design office because pulling force is transferred into the ship structure.
• As a supply product from long-term partner factories, quotation can be prepared with model selection, GA drawing, hydraulic schematic, and certificate scope according to customer requirement.

Custom Attributes

• Product Category: Electric hydraulic mooring capstan → ship deck machinery for rope pulling and warping, not a rope storage winch.
• Supply Model: Partner-factory supply → suitable when the customer requires reliable cost control, technical coordination, and project documentation.
• Working Load: 5–250 kN → selected according to rope handling force, vessel size, and deck arrangement.
• Speed: 9–18 m/min → selected according to operation frequency, safety control, and hydraulic power capacity.
• Rope Diameter: 11–46 mm → should be confirmed together with rope material and warping head contact condition.
• Warping Head Diameter: 250–700 mm → selected to match rope size and improve line grip during operation.
• Drive Type: Electric hydraulic → electric motor drives the hydraulic pump, which powers the hydraulic motor and reducer.
• Control Type: Lever / proportional control → proportional control is recommended when smooth speed regulation is important.
• Mounting Type: Vertical or horizontal deck-mounted arrangement → selected by rope lead direction and available deck space.
• Certificate Requirement: Available according to order scope → class inspection, maker certificate, material certificate, and test report should be confirmed before quotation.

How It Works

Electric motor drives the hydraulic pump → Hydraulic oil powers the hydraulic motor through control valves → Gear reducer transmits torque to the warping head → Rope is wrapped around the capstan head for frictional pulling → Operator controls rope movement through local or remote control → Rope leaves the capstan without being stored on a drum

Applications

Tugboats | Small vessels | Harbor operation vessels | Workboats | Mooring stations | Auxiliary rope handling on larger ships | Shipyard line handling | Port service vessels | Offshore support vessels subject to project requirement

Certifications & Advantages

Certificates can be arranged according to project requirement, inspection scope, material traceability, hydraulic system documentation, and class society approval procedure.

Certification: CCS, NK, BV, ABS, DNV, LR, KR, IRS, RS, RINA, CRS, Makers Test Certificate.

FAQ

Q1: What is the difference between a capstan and a winch?

A1: A capstan uses a warping head to pull rope continuously by friction and does not store the rope on a drum. A winch normally includes a drum and is used to pull, hold, and store rope or wire rope on the drum.

Q2: Can this capstan be used for towing?

A2: It can assist rope handling during harbor or deck operations when specified, but it should not be treated as a certified towing winch by default. If towing-related duty is required, the working load, rope size, duty cycle, foundation, brake / holding function, and class approval requirement must be confirmed.

Q3: What information is needed before quotation?

A3: Please confirm working load, speed, rope diameter and material, warping head requirement, vertical or horizontal mounting, power supply, hydraulic power unit layout, control type, certificate requirement, quantity, delivery destination, and installation drawing if available.
