Small dredger boat 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 dredger boats 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 dredger boat; at the end the slurry will be discharged by pipeline on land to the required place.
The small dredger boat 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 dredger boat 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 dredger boat: 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 dredger boat have a test before ex-factory?
Answer:
Yes, it must be. Each small dredger boat must be tested very well before ex-factory so that can guarantee river cutter 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 river cutter dredger will be transported to the port for loading.
How is the small dredger boat transported?
Answer:
There are two ways forsmall dredger boat being transported, if the sand dredger size smaller than JMD350, it is easy to transported by containers; if the river cutter dredger size is larger than JMD350, it will be transported by bulks. The small dredger boat 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 dredger boat arrive at clients' working site, we will send two experienced engineers forsmall dredger boat body assembly and native workers' training. With the assist of ancillary equipment like excavators and cranes , the cutter dredger assembly can be finished within 10days and training can be in one week.
