Product Description
Electro-Hydraulic Vertical Anchor Capstan with Warping Head for Ship Anchoring and Mooring
Product Overview
This electro-hydraulic vertical anchor capstan is a vertical-axis marine deck machine for handling a vessel’s anchor chain and, when fitted with the upper warping head, for controlled rope warping. The cable lifter / gypsy engages the stud-link anchor chain, while an electric-motor-driven hydraulic power unit supplies the hydraulic motor and reduction drive. The vertical arrangement can reduce horizontal deck-space demand and allows the drive layout to be coordinated with available above-deck and below-deck space.
Selection should be based on the certified anchor-chain diameter and grade, anchor mass and anchorage depth, required continuous-duty pull and recovery speed, warping requirement, brake and chain-stopper arrangement, hydraulic power unit, chain lead, foundation and class / flag requirements. Chain working pull, warping-head pull and brake holding capacity are different engineering ratings and should not be combined under one generic SWL. This equipment is for anchoring and rope warping, not cargo or personnel lifting.
Quick Specifications
- Equipment type: Vertical anchor capstan with warping head → combines anchor-chain handling and rope warping on a compact vertical-axis arrangement.
- Chain diameter range: 12.5–60 mm in the supplied parameter table → the cable-lifter pocket must match the actual chain diameter, pitch and link geometry.
- Chain grade basis: Grade 2 / AM2 and Grade 3 / AM3 reference columns → final designation should match the chain certificate and applicable class rules.
- Reference continuous-duty pull: 6.6–171.0 kN across the supplied range → use as a selection reference; final design pull is subject to approved project calculations.
- Nominal chain recovery speed: 9 m/min in the supplied table → performance must be checked together with anchor mass, anchorage depth and drive duty.
- Warping load: 5–140 kN in the supplied table → this is a separate rope-handling rating and is not the anchor-chain working pull or brake holding load.
- Drive: Electro-hydraulic → HPU pressure, flow, motor displacement, cooling, filtration and relief settings are project-specific.
- Installation: Vertical shaft arrangement → chain lead, deck penetration, foundation stiffness, under-deck reinforcement and maintenance access must be coordinated with the vessel GA.

Selection & Inquiry Guide
Step 1: Confirm anchoring data: anchor mass, certified chain diameter and grade, chain length, anchorage depth, chain stopper / securing arrangement and required chain recovery performance.
Step 2: Confirm performance: required continuous-duty pull, nominal speed, temporary overload requirement if applicable, brake holding requirement and warping-head pull. Keep these ratings separate.
Step 3: Confirm rope warping data: rope type, rope diameter, required warping pull, rope lead direction and the required warping-end profile / size.
Step 4: Confirm electro-hydraulic system: ship power supply, HPU arrangement, local / remote control scope, emergency stop, alarms, interlocks and any monitoring signals.
Step 5: Confirm installation: above-deck / partly below-deck / below-deck drive arrangement, hawse pipe, cable-lifter centreline, spurling pipe, chain locker, deck penetration, foundation and maintenance-removal space.
Step 6: Provide quantity, vessel type, classification society / flag requirement, coating and inspection scope, GA or installation drawing, delivery destination and required delivery time.

Anchoring, Drive & Installation Advantages
- Vertical-axis arrangement concentrates the cable lifter and warping head around one shaft line, which can simplify deck layout where horizontal machinery space is limited.
- Electro-hydraulic drive allows low-speed torque and speed control to be coordinated with the actual chain pull and operating duty; hydraulic pressure, flow and relief settings remain project-specific.
- Cable-lifter geometry is selected against the actual anchor chain. Correct pocket engagement is important for stable chain seating and to reduce shock, jumping and local wear.
- Working pull, temporary overload, brake holding condition and anchor securing are reviewed as separate load cases. The chain stopper and other securing devices should be coordinated with the complete anchoring arrangement.
- Foundation design should consider the real chain lead and load transfer into the vessel structure. Deck penetration, reinforcement, welding / bolting details and removal access should follow the approved vessel drawing.
- For classed projects, drawings, calculations, material traceability, hydraulic / electrical documentation and factory test records can be prepared within the agreed approval and inspection scope.
- Custom Attributes
- Product Type: Vertical anchor capstan with warping head → anchor-chain handling plus rope warping on a vertical shaft.
- Primary Drive: Electro-hydraulic → electric motor powers the HPU; hydraulic motor drives the vertical shaft through reduction gearing.
- Chain Range: 12.5–60 mm → based on the supplied table; actual gypsy profile must match the certified chain.
- Chain Grade: Grade 2 / AM2 and Grade 3 / AM3 reference → final chain designation and properties to be confirmed from project documents.
- Nominal Speed: 9 m/min → supplied table value for anchor-chain recovery.
- Warping Load: 5–140 kN → supplied table range; separate from anchor-chain pull and brake holding capacity.
- Control: Local control as project basis; remote functions → to be confirmed together with alarms, interlocks and emergency-stop philosophy.
- Foundation / Deck Interface: Project-specific → confirm shaft centreline, chain lead, deck opening, reinforcement and drive-removal access.
How It Works
Anchoring: HPU starts → hydraulic motor develops torque → reduction gear turns the vertical shaft → cable lifter heaves in or pays out anchor chain → brake / chain stopper secures the chain as required | Warping: warping head rotates → rope is wrapped around the head → friction transmits controlled pull → operator tends the rope; the warping head is not a rope-storage drum.
Applications
Cargo ships | Tankers | Bulk carriers | Workboats | Tugboats | Barges | Sea-going vessel anchoring stations | Newbuilding projects | Deck machinery replacement projects
Certifications & Advantages
ISO 4568:2021 is a current international reference for the design, construction, safety, performance and acceptance testing of sea-going vessel windlasses and anchor capstans, including hydraulic drive. ISO 6482:2017 covers warping-end profiles, while ISO 1704:2022 covers the shape, proportions, dimensions and tolerances of stud-link anchor-chain components. Applicable class, flag and approved project requirements take precedence.
Factory acceptance testing can be arranged according to the approved specification and agreed inspection scope. ISO 4857:2023 provides factory acceptance test procedures and methods for assembled windlass and winch systems.
Certificates and class witnessing are available according to project requirement, approved inspection scope and classification society procedure; they are not assumed to be included by default.

FAQ
Q1: Is this the same as a normal mooring capstan?
A1: No. The anchor-capstan function uses a cable lifter / gypsy to handle anchor chain. The upper warping head handles rope by friction. A combined unit can provide both functions, but chain pull, warping pull and brake holding capacity remain separate ratings.
Q2: What determines the correct chain size and drive rating?
A2: Start with the certified chain diameter and grade, anchor mass, anchorage depth, required continuous-duty pull and recovery speed. The cable-lifter pocket must match the actual chain geometry. The hydraulic motor and HPU are then selected from the approved load, speed, duty and efficiency calculations.
Q3: What should be provided before quotation?
A3: Provide anchor and chain data, required pull and speed, brake / chain-stopper arrangement, warping-rope data, ship power supply, control requirement, vessel GA / foundation information, class requirement, inspection scope, quantity, destination and delivery time.
