Advanced Self-Propelled Harbor Dredger for Modern Marine Operations
The self-propelled harbor dredger is a critical machine for maintaining navigable waterways, ports, and offshore infrastructure. One of the most advanced systems in this category is the DRAGFLOW DRH400 self-propelled dredge with steel cables, engineered for deep harbor dredging, high-capacity slurry handling, and extreme marine environments.
Supplied by Ace Centro Enterprises (ACE), the DRH400 combines powerful hydraulic dredging technology, modular pontoon design, and steel cable stability to deliver exceptional performance in demanding harbor applications.
DRH400 Self-Propelled Harbor Dredger – Built for Heavy-Duty Performance
The DRH400 self-propelled harbor dredger is designed to operate efficiently in deep-water ports and high-sediment environments. Its steel cable positioning system ensures stability and precision during continuous dredging operations.
At the heart of the system is the powerful DRAGFLOW HY400 hydraulic dredging pump, engineered to handle abrasive and high-density slurry with maximum efficiency.
Key Applications:
Harbor and port dredging
Channel deepening and maintenance
Offshore platform support dredging
Sand and sediment removal
Mining and industrial slurry pumping
Oil spill cleanup operations
Tunneling and bentonite pumping
Sewage and wastewater dredging
Dam and dike construction
River and canal cleaning
High-Efficiency Hydraulic Pump System
The DRH400 self-propelled harbor dredger is powered by an advanced hydraulic dredging system designed for maximum performance in harsh marine environments.
Pump Features:
High-efficiency agitator for solid material handling
Handles slurry with specific gravity up to 1.7
Efficient transport of mud, sand, silt, gravel, and sludge
