1.  Hydraulic sand dredger/ dredger boat/ dredger machinery

The dredger we produce is self-propelled or non self-propelled, portable cutter suction dredger. The hull uses dismantle and box-like structure, which equipped with horizontal shifting devices, cutter ladder lifting devices, spud devices, deck crane and so on. It can also be equipped with anchoring poles and trolley devices. Generally, it has functions on dredging, conveying and discharging of mud and sand. It can produce certain amount of vacuum by the centrifugal pump.

-The dredge pump is driven by the main diesel engine through the reducing gear box.

-The Alternator, which driven by the auxiliary diesel engine supplies electricity for power and lighting of the whole dredger. Generator sets supplies electricity for lighting and emergency use when it doesn’t working.

-Cutter head is driven by hydraulic motor; cutter bearing has lubrication seal-in units.

-The dredger is moved by alternate swing of the spuds. The spuds are lifted by the hydraulic cylinder.

-The shifting winches, cutter ladder and lifting winch are driven by the hydraulic motor.

-The hydraulic oil pump is driven by the auxiliary diesel engine. 

 2.  Functions of cutter suction dredger

-Functions of cutter suction dredger: dredging river, dredging sand, desilting, reclamation for channels and land, and building roads.

-Applicability this machine: To 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 cutter suction dredger: sea, port, lake, and river.

-Soil conditions: relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on.

 4. Pontoons of the cutter suction dredger

 There are 3 pontoons in dredger, which including 1 main pontoon and 2 side pontoons. And also pontoons are dismantle type can be different parts in order to transported convenient by truck, then installation at working site.

5. Pipelines and floaters.

Usually, There are steel pipelines and PE pipelines, customers can buy them from us or themselves. If customers have special requirement, the pipeline and the floater can be custom made by suppliers. In packaging, pipelines and floaters are put into 40" high container for shipping. 

Generally, customers need to buy more pipelines. That’s because pipelines can be bend for time saving. 

Sand and mud is conveying and discharging by pipeline and floater.
