The invention is a device to reduce cable wear and tear by allowing the cable to slowly be spooled over onto, or over from an additional winch (2), from or onto the main winch (1). The additional winch is mounted at the opposite end of the cable (3) compared to the main winch. The invention includes means to allow this spooling over to happen by itself, without human supervision or intervention being required. In this way, by allowing the additional winch to position shift the cable in relation to the segments of it rolling most frequently back and forth on the main winch, wear and tear is distributed over a larger portion of the cable, and the cable's life time is extended. In this way the invention becomes a substitute for manual slip and cut operations, which are used as a method for extending life time on cables in derricks. The invention is primarily intended for use with winch activated wave power plants, where long-term reliability, combined with low maintenance costs, is particularly desirable. |
