Stationary Cutter Suction Dredger
Our stationary cutter suction dredger uses a cutter head to loosen underwater materials and a dredging pump to transfer the resulting slurry through discharge pipelines. The dredger is positioned by anchors and spuds, with transverse swinging movement during excavation. This working arrangement is suitable for river dredging, channel maintenance, sand mining and hydraulic reclamation projects.
The dredging system can handle materials including loose silt, fine sand, medium-coarse sand, soft clay, weathered muddy soil, cemented sediment, coral rock and limestone, subject to the selected dredger configuration and site conditions.

Dredging and Positioning Configuration
The main equipment includes the hull, cutter head, cutter ladder, dredging pump, discharge pipeline, power system, hydraulic system and positioning equipment.
- Cutter system: Cutter head, cutter ladder, gear reducer and winches.
- Pumping and delivery system: Dredging pump, drive system, floating pipeline, rubber hoses and shore discharge pipes.
- Positioning system: Spuds, anchors, side winches and steel cables.
- Hydraulic and control components: The published RYD550 configuration lists VICKERS hydraulic pumps, hydraulic motors using SAI technology, REXROTH valves and a Siemens PLC control system.
The dredger can alternate between anchor and spud positioning and swing transversely during excavation. The control system allows operation from the cabin.
