China Cutter Suction Dredger

China cutter suction dredger is a self-propelled or stationary vessel that uses a rotating cutter head to loosen the material in the hard ground (so-called cutting).

1.How does cutter suction dredger work?

China cutter suction dredger is positioned on spuds and anchor winches to ensure the vessel is firmly anchored during dredging. The cutter ladder is lowered. By pulling on the side wires, the cutter head is moved sideways, swinging around the main spud. China  cutter suction dredger moves forward by means of the spud carriage.

2.Where can the cutter suction dredger used?

China cutter suction dredgers are mainly used for capital dredging, especially when reclamation is associated with the dredging. Smaller vessels can be dismantled into sections and moved by road or rail for work in inland waterways, sludge lagoons, reservoirs and similar isolated areas. Large heavy-duty cutter dredgers are capable of dredging some types of rock which have not been pre-treated.

3.What the features of cutter suction dredger?

1.combination of mechanical excavating and hydraulic dredging with centrifugal dredge pumps and a rotating cutter head
2.accurate dredging system with good control on vertical and horizontal position
3.transport of dredged materials through pipelines
4.dismountable and transportable over land
5.production of up to 6,000m3/hour
