high capacity cutter suction dredger for lake river channel dredging
Product Description
Julongdredgers can apply to all kinds of geologic structures and can be widely used in mineral digging, port dredging and reclamation works.
By absorbing advanced technology of Dutch and American related products, this series of dredgers show their characteristics of rational design, all hydraulic control, simple operation, little maintenance and strong power. The capacity of JLCSD dredgers ranges from 100m3/hr to 1000m3/hr, dredging depth from 1m to 25m and discharge distance from 500m to 3000m, which can satisfy different work demands.

General Considerations
The cutter suction dredger is a stationary dredger equipped with a cutter device (cutter head) which excavate the soil before it is sucked up by the flow of the dredge pumps.
During operation the dredger moves around a spud pole by pulling and slacking on the two fore sideline wires. This type of dredger is capable to dredge all kind of material and is accurate due to their movement around the spud pole. The stationary cutter suction dredger is to distinguished easily from the plain suction dredger by its spud poles, which the last don’t have.
The spoil is mostly hydraulically transported via pipeline, but some dredgers do have barge-loading facilities as well. Cutter power ranges from 50Kw up to 5000Kw, depending on the type of soil to be cut.
The ladder, the construction upon which the cutter head, cutter drive and the suction pipe are mounted, is suspended by the pontoon and the ladder gantry wire.
Seagoing cutter suction dredgers have their own propulsion that is used only during mobilization. The propulsion is situated either on the cutter head side or on the spud poles side.
Area of application
Cutter suction dredgers are largely used in thedredging of harbours and fairways as well as for land reclamation projects. In such cases the distance between the dredging and disposal areas is usually smaller than the distances covered by trailing suction hopper dredgers.
The cutter suction dredger also has the adbantage when an accurate profile has to be dredged. The cutter suction dredger cantackle almost all types of soil, although of coure this depends on the installed cutting power.
Cutter suction dredgers are built in a wide range of types and sizes, thecutting head power ranges between 20Kw for the smallest to around 4000Kwfor the largest. The dredging depth is usually limited; the biggest suction dredger canreach depths between 25 an 30m. The minimum dredging depth is usually determined by the draught of the pontoon.
