Abstract

A trailing suction dredger for working a subaqueous bottom comprises a floating vessel, a suction pipe 5 suspended from the vessel, and a trailing head 11 attached to the pipe. The trailing has a row of teeth 15 attached to it by means of a frame 18 which is vibrated by a vibrator 69 to increase the penetrating force when dredging stony bottoms. <IMAGE>
