Drag head and trailing suction hopper dredger
A drag head (100) for dredging material (2) from the bed (3) of a body of water and transporting the material (2) to a suction tube (120). The drag head (100) is arranged to be dragged over the bed (3) in a dragging direction (D). The drag head (100) includes a suction section (110) in which an under pressure can be created to suck up the material (2) from the bed (3) through a suction opening (113) into a suction chamber (112). A heel section (111) guides the drag head (100) along the bed (3). The suction section (110) is preferably rotatably connected to the heel section (111). The suction section (110) also includes an outlet (114) for transporting the material (2) towards the suction tube (120).
