Engine for the Cutter suction dredger
Cummins Engine is global warranty, spare parts can be available in short time.
Environmental protection and Energy conservation
The main engine driven the dredge pump and auxiliary engine drives hydraulic system including cutter, swing winches, ladder winch

and the spud rams etc. And the emergency genset supplies electricity for lighting and emergency use when the dredge doesn’t work.



Pump for Sand Cutter suction dredger
Shijiazhuang Pump adopted advanced worman technology.
1. Structure good, WN dredger pump adopts semi double shell structure, which reduces unnecessary auxiliary structure and process
structure.
2. Advanced hydraulic model, the efficiency is high. The efficiency of the WN mud pump is 2-3 percentage point higher than before.
In this way, lower energy consumption can be achieved at the same output.
3. Good wear resistance with long life.

Our dredger can also install Imported Original Pump from abroad.




Hydraulic system for the Cutter suction dredger

An integral hydraulic system includes hydraulic cutter head, hydraulic winch, hydraulic pump, hydraulic valve manifold, solenoid
valve, hydraulic pipes, hydraulic components, electrical actuator and so on. 
The hydraulic system requirements are very high and strict, it is the main artery of the entire dredger. The swing winches, lifting
winch and cutter head are all driven by separate hydraulic motors.
The spud cylinder is hydraulic powered to lift spuds, the alternate swing of spuds will move the dredger.

Be self-propelled for the China Made Cutter Suction Sand Dredger
Some dredgers do not have navigation capability, and they are always driven by tugboats 

Milestone dredger can be with the function of self-propelled, then easy to move for work.
