Abstract
The invention described consists of a dredger having a floating hull and a two-part boom attached to the hull and extending forwardly therefrom. The rear end of the first part of the boom is hinged to the hull about a horizontal axis, while its front end has a platform also hinged about a horizontal axis, with structure being provided to keep the platform horizontal when this first part of the boom is inclined using a jib and cable. On the platform is a component pivoted about a vertical axis and on this component is pivoted, about a horizontal axis, the second part of the boom, which performs a sweeping dredging movement and has at its front end a disintegrator tool, and the suction inlet of a pipe for removal of dredged material. The structure keeping the platform horizontal may be a mechanical parallelogram, or servo controlled jacks. Piles on the floating hull and on the platform serve to stabilize the dredger on the sea-bed.
