Electric secondary or storage winches offer a huge storage capacity for large diameter steel wire or synthetic ropes, which offer lower specific weight advantages over steel wire equivalents. The winches use adapted advanced variable frequency drive technology with smooth tension and speed control. A freshwater-cooled and hydraulically-driven multi-disc brake can be fitted to offer significantly increased speed for dynamic braking.
All winches are also available with low-pressure and high-pressure hydraulic drives.
