Cutter suction dredger is a hydraulic dredger that uses centrifugal pumps with a rotating cutter head to loosen, lift and transport dredged material. Dredging machines are non-propelled dredgers.
Working method: The cutter will be moored with spuds or anchors while at work so that in essence the dredging operation takes place with the cutter in a stationary position.
Project applications: Cutter suction dredgers are used wherever the seabed is hard rock. They are used for larger dredging projects such as navigation channels and port development and maintenance and land reclamation and in major projects such as the Panama Canal and the Suez Canal.
Types of dredging materials: Cutters are powerful and are capable of dredging all kinds of material in water including hard rock.
They are able to effectively dredge: silts, clays, sand, gravel, cobbles, fractured rocks and sound (unfractured) rocks.
Product Parameter

| CSD-500 | 3500 m3 /hr | 1.5-15 m | 600/500 mm | 1100-1600 kw |
| CSD-650 | 5000 m3 /hr | 1.5-18 m | 650/650 mm | 2200-2500 kw |
| CSD-700 | 7000 m3 /hr | 1.5-20m | 750/700 mm | 2800-3500 kw |
Advantage
● Heavy-duty, high concentration ratio, excellent particle allowance, and long discharge distance
● Optimal configuration of power and hydraulic unit (less operating costs)
● Dismountable structure, easy to disassemble, and transportation.
● Double powerful auger drive (infinitely for- and backward)
● High working range of the outrigger arm
● Equipped with a self-propulsion system that can be moved to a different work site or drag by tugboat
● Cutter suction head can be changed for different situation
● Easy access to all parts, especially the dredge pump wearing parts
● Freshwater cooling system
● Safe and easy to operate
● Can be designed and fabricated according to your requirements
