Dredger Machine Mining Vessels
The dredger we produce is self-propelled or non self-propelled,portable dredger machine mining vessels. 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 dredger machine mining vessels 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. Functions of dredger machine mining vessels: dredging river, dredging sand, desilting, reclamation for channels and land, and building roads. Working site of dredger machine mining vessels: sea, port, lake, and river. Soil conditions: relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on. |

The dredgers can be custom made according to customers’ requirements: 1. Anchor booms installation 2. Spud carriage 3. Dredger position of 5 anchors. 4. Hydraulic driving for spud flat down(to pass and transport on water safely). 5. Make the dredger with extra dredging pump underwater to deepen dredging depth for 20-30m underwater and slurry concentration is more than 30%. 6. Make the dredger with booster station to further the discharge distance. |
FAQ for Dredger Machine Mining Vessels
1) .Do your river cutter suction dredger have a test before ex-factory? Answer: Yes, it must be. Each cutter suction dredger machinery must be tested very well before ex-factory so that can guarantee cutter suction dredger performance at customers' working sites and save the time and cost for customers. Before test we will send invitation letters to the clients to invite them come and do the performance inspection by themselves, after get the clients permission and the cutter suction dredger will be transported to the port for loading.
2). How is the cutter suction dredger transported? Answer: There are two ways for cutter suction dredger being transported, if the cutter suction dredger size smaller than JMD350, it is easy to transported by containers; if the cutter suction dredger size is larger than JMD350, it will be transported by bulks. The cutter suction dredger structure is dismuntable and assembled so that can be easy transported by trucks on road.
3). What kind of service will supply after sales? Answer: After cutter suction dredger arrive at clients' working site, we will send two experienced engineers for cutter suction dredger body assembly and native workers' training. With the assist of ancillary equipment like excavators and cranes , the cutter suction dredger assembly can be finished within 10days and training can be in one week. |
