摘要
The invention relates to a grab dredger for conveying material deposited under water, with a floating body and a boom pivotably mounted on it and a pivotably mounted grab mounted on the boom. Due to the fully hydraulic functional movements and the exact guidance, it is possible to carry out programmed excavating or adapt to the conditions of the deposits at any time. In addition, no lateral forces at all occur on the floating body and thus no positional displacements occur. With this unit it is even possible to remove the surface of a mud layer.
