Features of Cutter Suction Dredgers:
1. Great Adaptability.
The cutter suction dredgers can be widely used in river, lake, sea, reservoir and so on for sand/mud dredging,
waterway cleaning and reclamaition work.
2. High Efficiency.
The cutter suction dredgers can dredge and discharge sand/mud at the same time without other ships for
transportation. So the cost will be much lower and they can reach big production capacity of several thousand
cubic meters per hour and also several thousand meters discharge distance.
3. Easy Operation.
With hydraulic system and PLC control system, all the dredgers operation can be done in the operation cabin.
4. Quick disassembly and assembly.
