Small dredging sand suction dredger is a small type hydraulic controlled, assembled river cutter suction dredger. It is used for river channel dredging, canal and water storage dredging. The dredger body 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 small dredging sand suction dredgers 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 small dredging sand suction dredger; at the end the slurry will be discharged by pipeline on land to the required place.
The small dredging sand suction dredger dredging devices are driven by hydraulic, concentrate controlled. The operator cabin is dismountable, which can lower the height of the dredger when maneuvering and allow the dredger to pass bridges easily and safely. When the dredger is transported long way from conjunctive water areas,the dredger body can be dismounted and transported by trucks or trains on road. The dredger can be fixed with anchoring booms and spud carriage.

Small dredging Sand Suction dredger can pass low bridge easily, the controlling room and rest room are dismountable. Connecting parts for cabin room and deck are easily dismounted joints,.Construction: it consists of three pontoons: one main pontoon and two side pontoons. The pontoons are connected by the connecting pieces and tightened by high intensity bolts and nuts.
Working site of small dredging sand suction dredger: sea, port, lake, and river.Soil conditions: relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on.
1. Anchor booms installation
2. Spud carriage
3. Dredger position of 5 anchors.
4. Hydraulic driving for spud flat down(to pass low bridge and transportation 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.
Do your small dredging sand suction dredger have a test before ex-factory?
Answer:
Yes, it must be. Each small dredging sand suction dredger must be tested very well before ex-factory so that can guarantee river 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 small dredging sand suction dredger will be transported to the port for loading.
How is the small dredging sand suction dredger transported?
Answer:
There are two ways forsmall dredging sand suction dredger being transported, if the small dredging sand suction dredger size smaller than JMD350, it is easy to transported by containers; if the small dredging sand suction dredger size is larger than JMD350, it will be transported by bulks. The small dredging sand suction dredger structure is dismuntable and assembled so that can be easy transported by trucks on road.
What kind of service will supply after sales?
Answer:
After small dredging sand suction dredger arrive at clients' working site, we will send two experienced engineers forsmall dredging sand 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.
