2. Cutter head river dredger
The cutter head river dredger we produce is self-propelled or non self-propelled,portable sand 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 river 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 river dredger; at the end the slurry will be discharged by pipeline on land to the required place. Functions of river dredger: dredging river, dredging sand, desilting, reclamation for channels and land, and building roads. Working site of river dredger: sea, port, lake, and river. Soil conditions for river dredger: relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on. |
Design
| Our cutter suction river dredgers are designed by senior engineer, who have specialized in shipbuilding and dredging work for many years, to guarantee their dredging work performance and practical well. |
