Φ64 mm Electro-Hydraulic Combined Anchor Windlass & Mooring Winch for Ship Deck

Product Overview

The Φ64 mm electro-hydraulic combined anchor windlass and mooring winch is a ship-deck machinery unit that combines powered anchor-chain handling with a separate mooring-drum function on one common drive arrangement. The cable lifter / gypsy engages the vessel’s 64 mm stud-link anchor chain for heaving and paying out the bower anchor, while the drum is used for the project-specified mooring rope operation. The anchoring and mooring functions share machinery space, but their load ratings, brake duties, rope or chain data, and class checks must be treated separately.

For a 64 mm chain, the anchor-windlass design basis depends on chain grade, maximum anchorage depth, certified chain breaking strength, chain-stopper arrangement, anchor particulars, and the selected classification society. The current IACS UR A3 reference formula gives approximately 174.1 kN continuous-duty pull for Grade 2 / AM2 and 194.6 kN for Grade 3 / AM3 when the maximum anchorage depth does not exceed 82.5 m. The final gypsy profile, brake capacity, hydraulic power unit, foundation, controls, and mooring-drum specification should therefore be confirmed against the vessel GA, chain certificate, and project approval requirements.

Quick Specifications

• Anchor chain diameter: Φ64 mm → the cable lifter / gypsy must match the certified chain diameter, pitch, link profile, and selected chain grade, not diameter alone.
• Chain grade: AM2 / AM3 project option → IACS windlass calculations use the corresponding Grade 2 / Grade 3 design basis; the actual designation should follow the chain certificate and class requirement.
• Reference continuous-duty pull: 174.1 kN (AM2) / 194.6 kN (AM3) at anchorage depth ≤82.5 m → corrects the 153 / 171 kN figures, which correspond to a 60 mm chain in common windlass tables.
• Temporary overload pull: at least 261.2 kN (AM2) / 291.9 kN (AM3) for at least 2 minutes → provides the short-term breakout capacity required above the continuous-duty pull.
• Anchor-chain hoisting speed: ≥9 m/min → equal to the IACS UR A3 reference minimum mean recovery speed under the specified test condition.
• Brake / holding basis: 45% of certified chain MBL when an independent chain stopper is fitted, or 80% when no chain stopper is fitted → brake capacity is not a generic SWL.
• Drive arrangement: electro-hydraulic → electric motor drives the hydraulic power unit and the hydraulic motor transmits torque through the gearbox; published 55 kW power is a reference value and requires project confirmation.
• Reference configuration: single gypsy + single mooring drum → consistent with the supplied product-photo labels and current product-page title; final handedness, shaft arrangement, drum pull, and rope capacity are to be confirmed by GA drawing.

Main Technical Parameters

Main selection data for the Φ64 mm combined anchor windlass and mooring winch. Values identified as reference or to be confirmed should be finalized against the approved project data.

Engineering Note: The 174.1 / 194.6 kN values are windlass continuous-duty pull references for one anchor at a time and an anchorage depth up to 82.5 m; they are not product SWL values. For anchorage depths above 82.5 m, an additional depth term applies. Brake holding, chain stopper, deck foundation, and mooring-drum ratings are separate design checks.

Selection & Inquiry Guide

Step 1: Confirm anchor-chain data → Φ64 mm chain, AM2 / AM3 grade, chain certificate, pitch / link dimensions, certified minimum breaking load, anchor mass, and maximum anchorage depth.

Step 2: Confirm anchoring performance → required continuous pull, short-term overload pull, recovery speed, number of anchors operated at one time, and whether an independent chain stopper is fitted.

Step 3: Confirm mooring-drum requirement → rope type, diameter, MBL, required first-layer pull, working speed, storage capacity, number of layers, and preferred drum / warping arrangement.

Step 4: Confirm deck arrangement → hawse-pipe lead, chain stopper position, chain locker lead, gypsy centerline, rope lead / fleet angle, machinery handedness, maintenance access, foundation, and local deck reinforcement.

Step 5: Confirm electro-hydraulic system → ship power supply, motor rating, hydraulic pressure and flow, HPU location, control station, manual proportional control requirement, protection / relief-valve arrangement, and emergency operation requirement.

Step 6: Confirm commercial and approval scope → classification society, drawing approval / survey requirement, FAT and onboard test scope, surface treatment, quantity, delivery destination, required delivery time, and vessel GA or reference drawing.

Windlass, Hydraulic & Installation Engineering Advantages

• The cable lifter is selected to the actual 64 mm certified anchor chain; chain grade, pitch, link geometry, and gypsy pocket matching are engineering inputs because incorrect chain-to-gypsy engagement can cause poor seating, impact loading, and abnormal wear.
• The anchor drive is sized from continuous-duty pull, short-term overload capacity, hoisting speed, and maximum anchorage depth rather than from one generic 'anchor load'. This separates normal recovery duty from temporary anchor-breakout duty.
• Gypsy clutch and brake functions allow the cable lifter to be disengaged from the powered shaft and the anchor chain to be controlled independently. Brake holding requirements must be checked together with the actual chain stopper arrangement and certified chain MBL.
• Electro-hydraulic drive provides flexible torque control and allows the HPU to be arranged to suit vessel layout. System pressure, relief settings, hydraulic motor type, oil cleanliness, cooling, and pipe routing should be defined in the approved hydraulic schematic.
• Combining the windlass and mooring drum can reduce separate machinery footprint and centralize operation, but the anchor-chain lead and mooring-rope lead must remain correctly aligned and should not be treated as one common load path.
• Deck foundation, holding-down arrangement, surrounding deck reinforcement, shaft alignment, hawse-pipe lead, chain-stopper alignment, and maintenance clearances should be reviewed with the shipyard before production and installation.

Custom Attributes

• Product Type: Combined anchor windlass & mooring winch → one deck machinery unit provides powered anchor-chain handling plus a separate mooring-drum function.
• Anchor Chain: Φ64 mm stud-link chain → gypsy profile must match the certified chain dimensions and project chain grade.
• Chain Grade: AM2 / AM3 → changes the required continuous-duty pull and short-term overload basis.
• Anchoring Pull: 174.1 kN AM2 / 194.6 kN AM3 reference → applicable to the standard ≤82.5 m anchorage-depth basis before any deeper-water addition.
• Brake / Chain Stopper: Project-specific → 45% or 80% of certified chain MBL is used according to the approved chain-stopper arrangement.
• Drive Type: Electro-hydraulic → electric motor + HPU + hydraulic motor + gearbox; final pressure, flow, motor power, and cooling are project-specific.
• Mooring Drum: Rating to be confirmed → rope diameter, MBL, capacity, first-layer pull, speed, and brake requirement must be supplied for final selection.
• Control & Approval: Manual proportional / local or remote control as specified → final safety functions, survey, FAT, and certification scope follow project and class requirements.

How It Works

Ship electrical supply powers the hydraulic pump unit → pressurized oil drives the hydraulic motor → gearbox transmits torque to the main shaft → engaged gypsy clutch rotates the Φ64 mm cable lifter for heaving / paying out anchor chain → anchor brake and chain stopper control / secure the chain as arranged → mooring drum operates the specified rope independently through its clutch / brake arrangement → local or remote controls regulate direction and speed

FAQ

Q1: Are 174.1 kN and 194.6 kN the SWL of the Φ64 mm windlass?

A1: No. They are reference continuous-duty anchor-chain pulls for 64 mm Grade 2 / AM2 and Grade 3 / AM3 chain under the IACS UR A3 basis for anchorage depth up to 82.5 m. They should not be described as a generic SWL or as the mooring-drum rating.

Q2: Why does the chain-stopper arrangement affect the brake / holding requirement?

A2: The windlass holding-load and brake design case is related to the certified chain minimum breaking strength. Under the IACS UR A3 basis, 45% of chain MBL may be used when an independent chain stopper is fitted; without a chain stopper, the brake must be checked at 80% of chain MBL. The actual arrangement and chain certificate must therefore be confirmed before final design.

Q3: What information is required for a reliable quotation and GA drawing?

A3: Provide the 64 mm chain grade and certificate data, anchor mass, maximum anchorage depth, hawse pipe and chain-stopper arrangement, mooring-rope diameter / MBL / capacity, required drum pull and speed, ship power supply, HPU arrangement, machinery orientation, deck foundation information, classification society, quantity, destination, and required delivery time.
