    Description

    The Anchor Handling Towing Winch (AHTW) is mechanical device, it is often with double drum, we call it waterfall winch, the upper drum is for towing, the lower drum is for anchor handling, if the load capacity is big, then the speed will be slow, the towing line can reach 500-1500 meters. It also can be three drums or add the side cable lifter according to requirements.

    Engineered Capabilities & Core Configurations

    Our integrated winch suites are built to comply with strict international maritime regulations and can be customized to match your specific hull design and deck footprint:

    Multi-Drum Versatility
    Available in double or triple drum configurations (waterfall or side-by-side layouts) to allow seamless shifting between independent anchor handling and heavy ocean towing operations.
    Dynamic Render & Recovery (R&R)
    Equipped with advanced hydraulic or electric drive systems that automatically adjust line tension in real time, absorbing massive kinetic shocks caused by heavy wave action.
    Heavy-Gauge Structural Integrity
    Built exclusively from high-strength marine steel plates (such as Class-approved GB/T Q355B or higher) with fully reinforced main shafts, drum shells, and heavy-duty foundation frames.
    Fail-Safe Multi-Disc Braking
    Features robust, high-holding hydraulic braking architecture capable of instant lockdown to securely hold ultimate breaking loads under static conditions.
