2. Hydraulic cutter suction dredger

The hydraulic cutter suction dredger we produce is self-propelled or non self-propelled,portable hydraulic suction dredger. The hull uses dismantle and box-like structure, Its dismantle type can be assembly at working place easily and be transported by road, railway and container accordingly, convenient in installation and working place moving from one to another. The power system can be designed to electric system or diesel engine driving system according to customers’ requirements.Equipment on thehydraulic cutter suction dredger are as bellows: traversing device, cutter ladder lifting device, spuds and deck crane. The hydraulic cutter suction dredger working process is as following: the cutter head cut the sand and mud underwater to mixture of slurry, then through dredging pump to the pipeline on hydraulic cutter suction dredger; at the end the slurry will be discharged by pipeline on land to the required place.

Functions of hydraulic cutter suction dredger: dredging river, dredging sand, desilting, reclamation for channels and land, and building roads.

Working site of hydraulic cutter suction dredger: sea, port, lake, and river.

Soil conditions for hydraulic cuttter suction dredger: relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on.
