The HEKING HK400SD wetland excavator is a professional amphibious excavation machine developed for demanding wetland engineering, swamp construction, river dredging, and coastal maintenance projects. Designed with reinforced pontoons and a powerful hydraulic system, this heavy-duty excavator delivers reliable operation in soft ground, muddy terrain, marshland, and shallow water conditions where standard crawler excavators cannot operate efficiently.
With a total operating weight of 40 tons and an extended working reach of up to 18.7 meters, the HK400SD provides excellent excavation capability for large-scale environmental projects and infrastructure construction. The machine is widely used in river channel dredging, flood prevention projects, lake cleaning, wetland restoration, mining ponds, and offshore engineering support operations.
The amphibious undercarriage system features triple-chain reinforced pontoons that provide outstanding flotation and stability during operation. The low ground pressure design of only 0.14kg/cm² allows the machine to travel smoothly over unstable surfaces while minimizing sinking risks in muddy environments.
The HK400SD wetland excavator is equipped with a high-performance Cummins C8.3 or Isuzu 6HK1 turbocharged diesel engine. Delivering 183.9kW at 2200rpm, the machine offers strong power output and excellent fuel efficiency for continuous heavy-duty operation.
The advanced hydraulic system includes a Kawasaki T5V140DT variable plunger pump combined with a high-quality hydraulic valve system. This configuration ensures smooth movement, fast response speed, and stable digging force during dredging and excavation applications.
The machine delivers:
135kN bucket digging force
123.8kN arm digging force
9rpm swing speed
70% gradeability
4x116kN traction force
These specifications enable the HK400SD to handle demanding excavation tasks in wetlands, deep mud, and shallow water environments with excellent operational efficiency.
The reinforced amphibious pontoon undercarriage is one of the key advantages of the HK400SD. The 11400mm pontoon length and 1800mm pontoon width provide exceptional flotation and balance for difficult terrain conditions.
The machine uses four independent travel motors to improve maneuverability and traction in swamp and wetland environments. The robust pontoon structure is engineered for long-term durability under continuous heavy-duty operation.
For customers operating in deeper water environments, HEKING also provides optional additional pontoons and spud systems to increase stability and working depth capability.
This makes the HK400SD suitable for:
River dredging projects
Coastal engineering
Wetland restoration
Marsh excavation
Flood control construction
Environmental protection projects
Pond cleaning operations
Mining sediment removal
The HK400SD wetland excavator is designed for contractors, dredging companies, infrastructure developers, and government engineering projects across Europe, the Middle East, Southeast Asia, Africa, and South America.
The machine is manufactured under strict quality control standards and supported by professional production facilities. HEKING has obtained multiple certifications including ISO9001 quality management system certification and CE certification for wetland hydraulic excavators.
The excavator is suitable for export and international project procurement requirements due to its reliable component configuration, durable structure, and adaptable amphibious operating capability.
Production time is typically within 50 days after receipt of the 30% down payment. Payment terms are based on T/T with 30% advance payment and 70% balance before delivery.
