China hydraulic system cutter suction dredger, sand river pump dredger 

Cutter suction dredge is widely used in dredging project.It makes use of a cutter head equipted around the front of the water suction tube to loosen and cut the mud to be dredged. It pumps the dredged material via the mud flowing pipeline to the pile. The digging,transpating and discharging progress can be carried out at the same time.It's of high work efficiency and low costing.Cutter suction dredge is a good choice for underwater dredging.

Working theory :

The hull uses dismoutable 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 discharge of mud or sand. it can produce certain amount of vacuum by the centrifugal pump.

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.


The design, construction, quality inspection is according to the standards and regulations of CCS. The hull, machinery equipments and other spares are at the requirements of CCS.  The hull is square, cross keel, which is full welding steel structure. And authorized by CCS.

Applicability : 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.
