Introduction

Features

PRODUCT INTRODUCTION

The Marine Anchor Winch is a deck machinery solution purpose-built for raising, lowering, and securely holding ship anchors. Powered by electric, hydraulic, or diesel drive systems, the winch is engineered for continuous operation in the demanding marine environment. The winch is available in horizontal (widely used on commercial vessels) or vertical (commonly used on naval ships to save deck space) configurations. Core components include the bedplate, bracket, cable lifter (gypsy), brake, clutch, gearbox, and electric control system. Key specifications cover chain diameter (φ19–φ105mm), working load (15–523kN), rated hoisting speed (≥9m\/min), and static holding load. The winch is certified by major classification societies including CCS, ABS, BV, and DNV, and fully complies with international standards such as GB4447-92, ISO 4568, and ISO 9089.

FEATURES

1
Heaving — Retrieves the anchor and chain from the seabed or riverbed, enabling the vessel to resume navigation. The windlass must heave at a specified speed of at least 9 m/min, up to 15 m/min.
2
Letting Go / Dropping Anchor — Releases the anchor chain, allowing the anchor to sink under its own weight to secure the vessel. Average chain speeds vary between 5–7 m/sec during this operation.
3
Chain Handling & Control — Precisely controls the paying out and hauling in of the anchor chain via the cable lifter, ensuring smooth and reliable anchoring operations.
4
Mooring / Warping — Drums or warp ends fitted on the ends of the shafts permit handling of mooring lines, assisting in berthing, unberthing, or warping the vessel alongside a quay.

FAQ

What is the main structural difference between an Anchor Winch and a standard Line Handling Winch?

add subtract
Unlike conventional winches that wrap wire or synthetic rope onto smooth drums, an anchor winch (or anchor windlass) is uniquely engineered for high-tension anchor handling:Gypsy / Wildcat Wheel: Features a specially cast pocketed wheel (gypsy) tailored strictly to the pitch and diameter of stud-link anchor chains (e.g., 12.5 to 120+ chain size).High Breakdown Torque: Designed to pull the heavy anchor and suspended chain off the seabed from deep water, requiring significantly higher initial breaking/lifting torque.Integrated Chain Stopper & Stripper: Equipped with a mechanical chain stopper to take the static load off the winch when anchored, plus a chain stripper to prevent chain jamming inside the gypsy.

Why are Combined Anchor Mooring Winches preferred for modern ship forecastle decks?

add subtract
Vessel bow decks have strictly limited surface area, making multi-functional machinery the industry standard: Space & Weight Efficiency: A combined anchor mooring winch integrates one or two chain gypsies alongside standard mooring drums and warping heads onto a single drive frame. Flexible Operation: Allows the crew to handle anchoring during arrival/departure and switch seamlessly to line mooring once alongside the berth, saving up to 40% of deck footprint and installation piping/cabling.

How do I select the right drive architecture: Electric, Hydraulic, or Diesel Engine?

add subtract
Drive selection depends on the vessel's electrical power balance, operational environment, and duty cycle: Electric / VFD Anchor Winch: The most popular choice for commercial container ships, bulkers, and modern eco-vessels. Delivers quiet operation, stepless speed variations (soft start), high energy efficiency, and low maintenance. Hydraulic Anchor Winch: Preferred for offshore working vessels, tugboats, and vessels operating in freezing/wet climates. Offers extreme power-to-weight density, superior shock load absorption, and dynamic tensioning. Diesel Engine Driven Winch: Ideal for non-powered barges, pontoon dredgers, or remote offshore platforms where vessel electrical power is unavailable.

How does the manual/hydraulic band brake ensure safe anchor dropping and emergency stopping?

add subtract
Dropping anchor involves immense kinetic energy from free-falling chain and anchor mass: Controlled Free-Fall Dropping: Disengaging the drive clutch allows the anchor to drop under gravity, controlled precisely by heavy-duty woven lining drum band brakes. Redundant Holding Safety: The brake holding capacity is calibrated to withstand extreme surge forces (typically tested to 45% of the chain's Minimum Breaking Load) to hold the vessel securely without slipping even during storm conditions.
