SDW deck winches for high-voltage cable line of a source (sparker) are designed for temporary or stationary setup on sea vessels in order to provide hoisting operations and towing seismic sources during geophysical surveys in the water area. The winch is equipped with a high-voltage slip ring and water-resistant switch box for connecting a deck cable. Depending on the model, a drum’s rotation can be provided manually or by means of an electric drive via a worm gearbox and chain transmission with the possibility of a smooth variation in rotational speed. The design of electric drive allows one to statically stop the drum in any position. The winch electrical equipment is housed in a special case with IP 67 environmental protection.
