Structure for JMD350 14 inch cutter suction dredger 

The dredger we produce is self-propelled or non self-propelled，portable cutter 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 the cutter suction dredger are as bellows: traversing device, cutter ladder lifting device, spuds and deck crane. The 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 dredger; at the end the slurry will be discharged by pipeline on land to the required place.
