Reliable Solution for Jetty Maintenance and Sediment Removal
Jetty structures are constantly exposed to sediment buildup caused by tides, currents, and marine activity. To maintain safe navigation and structural stability, efficient dredging equipment is essential. The DRH400 Self-Propelled Dredge with Steel Cables from is a high-performance jetty dredging machine designed for continuous sediment removal and marine infrastructure maintenance.
Powered by the advanced DRAGFLOW HY400 hydraulic dredging pump, the DRH400 ensures efficient dredging performance in confined jetty zones and deep-water access channels.
DRH400 Self-Propelled Dredge With Steel Cables
The DRH400 combines robust steel cable anchoring, modular pontoon construction, and high-capacity hydraulic pumping technology to deliver precise dredging around jetty structures.
