3. Cheap river/port dredging machine cutter suction dredger
The river/port dredging machine cutter suction 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. |

| 6. Different parts description of river/port dredging machine |
Design__Cutter suction dredger design meets the requirements and regulations of CCS, BV and ABS , which are belonging to IACS. The technology refer to Holland IHC, and dredger can be custom made according to customers' requirements. Chief engineer Gan attended the “Local cutter dredger design study on IHC Beaver” in 2000. Steel plate__ Raw material is marine use material which meets the requirements of CCS., and all plates are under sand blasting process. Hydraulic system__Hydraulic oil pipes made by pipe bending machine to decrease the welding points so that can keep system stability. When the oil pipe finish, should be acid picking and phosphating treatment to keep whole system clean and stability. Dredging pump__flow passage components use High wear resistant alloy Cr27 to prolonged the pump service life, pump shaft seal use packing seal which is easy to maintain , and anti-friction bearings are from Japanese brand NSK. |
