Abstract
Towing suction device for a dredging craft, which device comprises at least one tube which extends in a dredging position at an angle of inclination with the horizontal outboard along side the craft, in which a displacable tube part is disconnectably coupled with a tube part that is fixedly arranged on board, which parts are disconnected in the non dredging position. A coupling tube section of the displacable tube part is fastened on a slide, which is displacable along a guide track, placed above the water line, between the coupled and the disconnected position. The guiding track is arranged on a deck of the craft, whereas the coupling end of the fixed tube part is arranged near the guide track on the deck. Preferably the slide-guide track unit extends transversely to the longitudinal direction of the craft.

A suction device for a dredging craft comprising:
- a first tube affixed to said craft for receiving dredging discharge;
- a second tube having an upper end and a lower end, said second tube being positionable in a dredging position in which said tube extends along a side of the ship for inserting the lower end thereof in the water, said second tube having a dredging pump connected in the portion thereof that is immersed in the water when said second tube is in the dredging position;
- and
- a displaceable tube element having an outboard end coupled to said second tube and an inboard end coupleable to said first tube, said tube element being displaceably mounted on the craft for coupling and disconnection movement generally transversely of the side of the craft between a first position in which said inboard end is coupled to said first tube for delivering dredging discharge and a second position in which said inboard end is disconnected from said first tube.
