Abstract (en)
A suction dredger comprises a dredging tube (3) which at one end carries a suction head (4) and which at the other end is connected to the suction dredger hull (1) through a hull pivot (41) with a pivot axis which is generally transverse with respect to said hull, said dredging tube (3) comprising a tube (6,7) and a frame (8) which carries an upper tube part (7) of the tube (6,7) and which is connected to the hull pivot (41) through a first frame pivot (10) the pivot axis of which is transversely oriented with respect to the hull pivot axis of the hull pivot (41), a lower tube part (6) of the tube (6,7) being connected to the frame (8) through a second frame pivot (11) which is opposite the first frame pivot (10) and the pivot axis of which is transversely oriented with respect to the first frame pivot axis, a motor driven suction pump (31) being provided for transporting dredged material through the tube (6,7), said frame (8) having a cross-sectional contour defined by a height dimension and a transverse dimension. The upper tube part (7) over at least part of its length is positioned fully within the cross-sectional contour (38) of the frame (8).
