Abstract (en)
[origin: EP0185859A2] A dredger has a floating body (1) supporting a cross beam (3) provided with a travelling arm (4) for a travelling crab (5). The travelling crab (5) carries a lifting mechanism (6) for a grab (8), which can be raised and lowered via a rope (9). The weight of the grab is counter-balanced by a counter-balance weight (12), which is coupled via a rope (10) to the grab (8) so as to move in a counter direction to the grab when the grab is raised and lowered. The use of a counter-balance reduces the effective dead weight of the grab, improving the efficiency of the lifting mechanism. <IMAGE>
