Efficient Solution for Marina Maintenance and Sediment Control
Marinas require precise and continuous dredging to maintain water depth, ensure safe boat navigation, and prevent sediment buildup. The DRH400 Self-Propelled Dredge with Steel Cables from is a high-performance marina dredging equipment solution designed for efficient sediment removal in confined and sensitive marine environments.
Powered by the advanced DRAGFLOW HY400 hydraulic dredging pump, the DRH400 delivers reliable, controlled dredging performance ideal for marina basins, docks, and waterfront developments.
DRH400 Self-Propelled Dredge With Steel Cables
The DRH400 combines modular pontoon engineering, steel cable anchoring, and high-efficiency hydraulic pumping to ensure precise and stable operation in marina environments.
Key Applications in Marina Dredging
