The Mk7 Hydraulic Winch is designed for both free-swimming and Tether Management Systems (TMS) based Remotely Operated Vehicles (ROVs).
Designs have direct drive to the drum comprising of hydraulic motor, gearbox and integral disc brake unit. Winch in / out is controlled via a single lever. The lever provides precise control of the winch and load. Speed control is proportional to the movement of the lever. Releasing the lever activates the fail-safe brakes. A Wireless Remote Control can be added to operate the hydraulic winch from a safe location.
Umbilical spooling is achieved by guide rollers mounted on a diamond bar, chain-driven from the winch drum.
