2–300kN Hydraulic Mooring Capstan Winch | Marine Vertical & Horizontal Capstan

Product Specification

2–300kN Hydraulic Mooring Capstan Winch | Marine Vertical & Horizontal Capstan for Ship Deck

Product Overview

The 2–300kN hydraulic mooring capstan winch is a marine deck rope-handling machine used for mooring line handling, warping, controlled rope traction, and line adjustment on ship decks. It is driven by a hydraulic motor through a gearbox to rotate the warping head, providing high starting torque, adjustable line speed, and stable local or proportional control for deck operations.

This product should be understood as a hydraulic capstan for rope handling, not as a storage drum, anchor windlass, lifting winch, or dedicated towing winch. It can be supplied in vertical or horizontal configurations, and the installation can be arranged as fully recessed deck type, semi-recessed deck type, or surface mounted deck type according to the vessel layout, rope lead direction, deck opening allowance, foundation design, and maintenance access requirement.

Quick Specifications

• Working load: 2–300 kN → supplied selection range for rope-handling capacity; not to be converted into SWL, MBL, breaking load, or towing capacity without approved calculation.
• Warping head diameter: 250–800 mm → selected according to rope diameter, rope type, contact condition, and deck arrangement.
• Speed range: 5–30 m/min → affects line-handling efficiency and should be matched with hydraulic pressure and flow.
• Rope type: steel wire rope / synthetic rope → applicable rope type must be confirmed together with rope construction and surface contact requirement.
• Rope diameter range: 11–80 mm → key compatibility factor for warping head size and safe rope handling.
• Mounting type: vertical capstan / horizontal capstan → selected according to rope lead direction, deck space, and machinery layout.
• Installation type: fully recessed / semi-recessed / surface mounted deck type → selected according to deck penetration, foundation, maintenance access, and retrofit requirements.
• Control type: lever / proportional control → selected according to operating precision, control station arrangement, and hydraulic system design.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm working load, rope type, rope diameter, line speed, and application duty. The working load in this page is a supplied selection parameter and should not be treated as SWL, MBL, breaking load, test load, or towing capacity without approved calculation.

Step 2: Select capstan orientation. Vertical capstan is normally selected when a compact deck footprint and multi-direction rope handling are required. Horizontal capstan may be selected when the rope lead, machinery height, or deck arrangement makes a horizontal shaft layout more suitable.

Step 3: Select installation type. Fully recessed capstan keeps most machinery below deck and leaves only the warping head above deck. Semi-recessed capstan balances deck integration and maintenance access. Surface mounted deck type is retrofit friendly and normally avoids deck opening.

Step 4: Confirm deck foundation and installation interface, including deck penetration, base footprint, weld-down or bolt-down arrangement, local reinforcement, access space, and relationship with bollards, fairleads, rollers, and other rope-handling equipment.

Step 5: Confirm hydraulic system and control arrangement, including hydraulic pressure, flow, motor type, gearbox ratio, brake requirement, control valve, local control, proportional control, emergency stop, and remote control if required.

Step 6: Provide vessel type, installation position, rope specification, quantity, classification society requirement, inspection scope, GA drawing, deck structure drawing, delivery destination, and required delivery date.

Hydraulic Drive, Safety & Engineering Advantages

• Hydraulic drive provides high starting torque and adjustable operating speed, which is useful for controlled mooring line handling on deck.
• Vertical and horizontal capstan configurations allow the equipment to match different rope lead directions, deck layouts, and machinery space limitations.
• Fully recessed, semi-recessed, and surface mounted installation options help the shipyard balance deck space, deck penetration, maintenance access, and retrofit feasibility.
• Deck foundation design is a critical selection point. The capstan load path should be checked through the base frame into the supporting deck structure and local reinforcement.
• Recessed installation can reduce deck obstruction, but it requires deck opening design, below-deck clearance, drainage consideration, and maintenance access planning.
• Surface mounted installation normally simplifies retrofit work because the complete unit is installed above deck, but it requires enough deck space and clear rope lead arrangement.
• Brake system, hydraulic control valve, emergency stop, bearing arrangement, and lubrication points should be confirmed before production according to operating and class requirements.
• Working load, hydraulic power, rope diameter, and warping head size should be checked as a complete system rather than selected as independent values.

Custom Attributes

• Certificate Requirement: Available according to order scope → maker certificate, material certificate, class certificate, and witness inspection should be agreed before quotation.

How It Works

Hydraulic power drives the motor → Gearbox transmits torque to the shaft → Warping head rotates and grips the rope by friction → Operator controls speed and direction through the hydraulic valve → Reaction loads are transferred through the base frame into the deck foundation

FAQ

Q1: What is the difference between recessed and deck mounted hydraulic capstan?

A1: Fully recessed capstan places most machinery below deck and leaves only the warping head above deck, which helps reduce deck obstruction. Surface mounted capstan installs the complete unit above deck and normally avoids deck opening, making it more suitable for retrofit projects or vessels where deck penetration is not preferred.

Q2: How should vertical and horizontal capstan types be selected?

A2: Selection depends on rope lead direction, available deck space, foundation arrangement, maintenance access, and vessel deck layout. Vertical capstan is normally compact and suitable for multi-direction deck rope handling, while horizontal capstan can be considered when the rope lead or machinery arrangement requires a horizontal shaft layout.

Q3: What information is required for hydraulic system and deck foundation design?

A3: Please provide working load, rope type, rope diameter, required line speed, hydraulic pressure and flow, mounting type, installation type, control requirement, deck structure drawing, reinforcement detail, and classification society requirement. These items are required before confirming the model, foundation load, and quotation.
