Abstract

1383089 Suction dredgers HOLLANDSCHE AANNEMING MAATSCHAPPIJ NV 14 Aug 1973 [15 Aug 1972] 38030/72 Heading E1F A draghead 1 for a suction dredger comprises a first cutting element 2 for breaking up ground 3 over which the draghead is moved in order that it may be removed by suction through pipe 8, and a rotating cutting element 4 which is driven by a motor 6 to exert a force on the ground to assist movement of the draghead. The speed and/or torque of the motor 6 are controlled in dependence on the tension in the pipe 8, as measured by strain gauges 9. Cutting element 2 may comprise teeth carried by a part 11 pivotable about the axis 10 of the rotating cutter by actuator 21, or may be a driven cutter (20), Figs. 3, 5 (not shown) rotating in the opposite direction to cutter 4, which may comprise at least one pair of rotating elements whose axes are relatively inclined. The height of the cutting elements is adjustable by means of roller 12 and a shoe (18).
