| 3500m3 Cutter Suction Dredger for Sand Dredging |
Sand dredger suction dredger with cutter head 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. Research--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. |

How is the cutter sand dredger transported? Answer: There are two ways for river sand dredger being transported, if the sand dredger size smaller than JMD350, it is easy to transported by containers; if the sand dredger size is larger than JMD350, it will be transported by bulks. The river sand dredger structure is dismuntable and assembled so that can be easy transported by trucks on road. |
