The present invention relates to an improvement to dredging barges and more particularly to barges of modest overall dimensions, transportable by road in order to gain access to work sites of all types. The barge according to the invention comprises a hull 1 divided into compartments and a deck made from polyester around a rigid chassis on which are fixed, at the front, the means of dredging and laterally, means of the telescopic articulated leg type disposed, on the one hand, at the front in order to provide stabilisation and, on the other hand, at the rear to provide propulsion.read more

Bottom leveller system
TL;DR: In this article, a method of flat bottom dredging of a bed at least partially covered with liquid from a floating pontoon is described, which involves controllably rotating a ladder with a cutter head toward the bed to set the dredge depth and force with a first hydraulic system and adjusting the cutter head position with a second hydraulic system so that it is level with the bed.

Support leg arrangement for a work machine like a dredger
TL;DR: In this paper, the authors describe a support leg arrangement of a work machine that is meant to work in water systems in which the support legs are meant to extend to the bottom of the water system in order to keep the work machine in its place during the working in which case at least one pair of support legs consists of arms (3) which are at their upper end attached to the work machines with the help of a joint and the mentioned arms can be turned underneath the water surface with a power device, such as a hydraulic cylinder.

Aquatic harvester with improved flotation system
TL;DR: In this paper, an improved aquatic harvester is described, having an aquatic craft comprising a plurality of pontoons secured below a flat deck member, a pick-up assembly mounted on the forward end of the craft to collect aquatic material both at and below the surface of the water and an above-the-water propulsion and steering system having an air propulsion unit.
Patent
Engine for cleaning ponds, marshes or canals
TL;DR: In this article, a craft of the type comprising a support structure (4), provided with friction wedge (16) and equipped with a scraping member and movable cleaning (2,3), with respect to the structure around two vertical axes and horizontal, this member being controlled and operated from the cockpit located on the supporting structure.
