Today, Markey innovations have led to four classes of Hawser winches for ships working in dynamic offshore swells, through the break, and in-harbor:
- Class I “Basic” Hawser Winches feature moderate pull, high speed, high hold capacity static brakes, true freewheel and hawser tension monitoring, allowing operators to work more effectively.
- Class II Markey “Render/Recover”® Winches include Markey-pioneered automatic tension line control for tethered operations. Tugs safely maneuver through day-long escorts while the winch automatically adjusts scope to maintain preset line tension.
- Class “II+” Hawser Winches integrate electric motors, multi-disc clutches, and high hold dynamic slip brakes for fingertip control of the winch.
- Class III “ARR” Hawser Winches are ultra-high performance soft line winches for indirect towing in extreme seaways. Below deck or above deck electric drives and water cooled slip brakes ensure secure load control at full rated tug speed and bollard pull.
