Cutter suction dredger makes use of a cutter head to loosen the material to be dredged and pumps the dredged material via a pipeline ashore or into barges. The powerful cutter swings around the spud-pole powered by winches while dredging, then the high pressure sand pump suck up the loosened mixed materials to the destination through the suction pipe. The hydraulic cutter suction dredger is suitable for heavy duty and durable dredging operations with dismountable structure.
The hydraulic cutter suction dredger is often designed easily to transport by road, rail or by ship due to its reasonable size and weight of the various dismountable modules. The complete hydraulic cutter suction dredger consists of one main pontoon and two side pontoons which are mounted to the main pontoon using heavy duty steel eyes and pins at the bottom of the hull, they are connected at deck level. The pontoons are of welded steel constructions with heavy frames, beams and longitudinal girders. Extra reinforcements are placed where necessary to withstand all forces while dredging. It is widely used for river silt cleaning, delisting lakes and ponds, mining project, cleaning ports and sand production.
