The HK400SD Wetland Excavator is a professional-grade machine developed specifically for projects where conventional excavators cannot operate effectively. Designed for marshes, wetlands, swamps, tidal zones, shallow lakes, riverbanks, estuaries, and coastal engineering sites, this heavy-duty excavator combines powerful digging performance with outstanding flotation capability.
As a specialized Wetland Construction Excavator, the HK400SD allows contractors to perform excavation, dredging, environmental restoration, flood control, shoreline reinforcement, and infrastructure development in areas characterized by unstable soil conditions and water-saturated terrain.
The machine's advanced pontoon undercarriage distributes weight efficiently, creating an ultra-low ground pressure of only 0.14 kg/cm². This allows the excavator to travel safely across soft mud, marshland, peat soil, and swamp environments while minimizing environmental disturbance.
The HK400SD is powered by either the Cummins C8.3 or Isuzu 6HK1 turbocharged diesel engine, delivering up to 183.9 kW of power and 949 N·m of torque. This powerful drivetrain ensures reliable operation during continuous excavation and dredging tasks.
The hydraulic system features the Kawasaki T5V140DT variable plunger pump with a displacement of 2×140 cm³/r, providing smooth and responsive control under demanding conditions. Combined with high-performance hydraulic valves and motors, the system delivers exceptional efficiency for heavy digging, loading, dredging, and material handling applications.
With a bucket digging force of 135 kN and arm digging force of 123.8 kN, the HK400SD can tackle compacted soil, silt deposits, river sediments, and wet clay commonly encountered in dredging and wetland construction projects.
One of the key advantages of the HK400SD Marshland Excavator is its heavy-duty pontoon structure. The pontoons measure 11,400 mm in length and 1,800 mm in width, providing exceptional buoyancy and stability.
The wide undercarriage enables safe operation in challenging terrain where standard crawler excavators risk sinking or becoming immobilized. Four DOOSAN travel motors provide strong traction and precise maneuverability even when working in waterlogged environments.
For contractors involved in deep-water dredging, additional pontoons and spud systems can be installed to enhance stability and operational safety.
The HK400SD Wetland Construction Excavator is widely used in:
River dredging projects
Canal maintenance
Flood prevention works
Coastal engineering
Wetland restoration
Environmental remediation
Marshland development
Reservoir maintenance
Shoreline protection
Port and harbor construction
Its ability to operate in waterlogged and unstable environments significantly reduces the need for temporary access roads, work platforms, or costly ground stabilization measures.
The HK400SD is manufactured under strict quality management procedures and supported by professional production facilities. The machine is designed to meet the operational requirements of contractors, government agencies, dredging companies, and environmental engineering firms throughout Europe, the Middle East, Southeast Asia, Africa, and South America.
Production is completed within approximately 50 days after receipt of the down payment.
