PRODUCT INTRODUCTION

The Marine Towing Winch is a heavy-duty deck machinery solution purpose-built for towing, escorting, and anchor handling operations aboard tugs, anchor handling tug supply (AHTS) vessels, offshore support vessels, and salvage ships. Engineered for continuous high-load operation in demanding marine environments, towing winches deliver exceptional pulling force, robust brake holding capacity, and precise line control during critical towing maneuvers. Available in electric, hydraulic, and diesel drive configurations with single, double, waterfall, or split drum arrangements, the winch is fully customizable to specific vessel requirements. Rated line pull ranges from 10 to over 500 metric tons at the 1st layer, with brake holding capacity up to 670 metric tons. Key components include the electric motor or hydraulic power unit, induction-hardened gearbox, fail-safe braking system, rapid friction clutch release (under 3 seconds), and optional mechanical spooling device for wire rope. All systems comply with IACS rules and are certified by major classification societies including CCS, ABS, BV, and DNV. Advanced bridge control systems with local and remote operation, real-time line tension monitoring, and integration with vessel thruster controls ensure safe and efficient deck operations.

FEATURES

1
Provides high-load pulling force for harbor towing, coastal escort, and ocean towing operations. Line pull capacity up to 500+ metric tons.
2
Deploys, tows, and recovers mooring anchors for offshore platforms and AHTS vessels. Combines anchor windlass and towing winch dual functionality.
3
Delivers continuous escort force through real-time line tension adjustment, ensuring maneuverability and safety of escorted vessels in narrow channels or rough seas.
4
Provides line tension support for offshore platforms, FPSOs, and floating facilities by compensating for tide, wind, wave, and draft variations.
5
Delivers high-load pulling force for wreck removal, stranded vessel recovery, and emergency response operations. Supports rapid deployment.

FAQ

How do I correctly define the required Rated Line Pull and Brake Holding Power for a Towing Winch?

add subtract
Specifying a marine towing winch requires matching both working load and emergency survival conditions: Rated Line Pull (1st Layer): The dynamic pulling force the winch can deliver at specified speeds (typically ranging from 10 Ton to 250+ Ton for heavy AHTS vessels). Brake Holding Capacity: The static brake force required to hold the tow without slipping during severe wave surges. Industry standard dictates the brake capacity should be 2.0 to 3.0 times the rated dynamic line pull. Wire Rope Capacity: Sized according to towing distance and depth, specifying both rope diameter and length (e.g., 500m to 2000m).

Which drive system is better for marine towing applications: Hydraulic, Conventional Electric, or Electric VFD?

add subtract
The choice depends on vessel power distribution and operational priorities: High-Pressure Hydraulic (HPH): The traditional industry standard for extreme loads. Offers smooth low-speed high-torque control, inherent shock absorption, and high reliability in wet deck conditions. Electric Frequency Drive (VFD): Preferred for modern green vessels and offshore OSVs. Delivers up to 30% higher energy efficiency, lower noise, precise digital tension control, and eliminates hydraulic oil leakage risks. Low-Pressure Hydraulic: Ideal for severe dynamic marine environments requiring ultra-fast response and continuous heavy slipping capabilities.

How does the Emergency Quick Release (ESD) mechanism protect the tugboat from capsizing?

add subtract
During severe sea states or towline snags, an uncontrollable lateral force can capsize the towing vessel (girting). Our winches feature a redundant safety quick-release system:Multi-Location Triggering: Can be activated remotely from the wheelhouse bridge console, local deck panel, or radio remote control.Controlled High-Speed Release: Disengages the main drum brake hydraulically or pneumatically within<3{ seconds}, even under full brake holding load or dead-ship (power failure) conditions via stored accumulator energy.

Why is an automatic level-wind (auto-spooling) device essential for heavy-duty towing winches?

add subtract
High towing tension causes steel wire ropes to cut into underlying layers (wire bite) if spooled unevenly: Synchronized Diamond-Screw Spooling: Mechanically or hydraulically driven level wind guides the wire rope smoothly across the drum face at all fleet angles. Prevents Rope Damage & Jamming: Ensures uniform layer distribution, extending wire rope lifespan by up to 40% and eliminating dangerous line snaps during high-speed pay-out/reeling.
