<p>A trawl winch for fishing vessels (1) comprises two cable drums (5, 6) with each its trawl cable (8, 9), said drums being coupled to a common differential (4) with differential lock and where the power input device of the differential which is connected to the drive engine (3) may be blocked. The trawl (2) is a conventional trawl with otter boards (10). The trawl winch moreover comprises a blocking means which may block the power input device to the differential (4). When trawling, the connection between the drive engine (3) and the differential (4) is locked so that the two drums (5, 6) will be freely rotatable, but in opposite directions. This means that the two cables (8, 9) will always be equally loaded.</p> |
