1. About Leader Dredger Cutter Suction Dredger:
1. CCS ISO9001:2008 Certificate;
2. The cutter suction dredger ship is a kind of dismountable cutter suction dredger and non-propelled;
3. The cutter is directly driven by one low speed hydraulic motor;
4. The two spuds are operated by means of a hydraulic ram;
5. Oil for the hydraulic system is supplied by vane pumps.
2. Cutter Suction Dredger Introduction:
1. Cutter suction dredger is a kind of dredging equipment used for riverbed dredging, port dredging or canal construction projects.
2. The equipment adopts a front cutter head design, driven by a motor, which mixes sand and water.
3. There is a suction pipe behind the cutter head connected with the mud pump on the deck.
4. The marine diesel engine drives the mud pump to transport the mud-water mixture to the shore or recovery area.
5. In order to keep the dredger stable and working in the water, a pile made of two long steel pipes is vertically installed at the tail of the dredger. The stakes work like two legs and are rooted in the river bed driven by hydraulic cylinders. It can provide the supporting force when the front cutter head swinging arm is working.
