The HK400SD Swamp Excavator is a professional heavy-duty machine developed specifically for contractors working in wetlands, marshlands, riverbanks, floodplains, lakes, reservoirs, coastal areas and other soft ground environments where conventional excavators cannot operate efficiently.
Designed with a large flotation pontoon system and low ground pressure undercarriage, this Swamp Buggy Excavator can travel safely across unstable surfaces while maintaining excellent operational stability. The machine is widely used for river dredging, environmental restoration, flood prevention projects, coastal engineering, canal maintenance and wetland development.
For contractors seeking a reliable Marsh Excavator capable of handling demanding working conditions, the HK400SD provides the power, reach and durability required for long-term operation.
The HK400SD is equipped with a powerful Cummins or Isuzu engine delivering up to 183.9 kW of power. Combined with the Kawasaki T5V140DT hydraulic pump system, the machine provides strong hydraulic output and efficient fuel utilization.
The advanced hydraulic system ensures smooth operation during digging, dredging, lifting and material handling tasks. High bucket breakout force and arm digging force enable the excavator to work efficiently in dense mud, clay, sediment and underwater materials.
With a maximum bucket digging force of 135 kN and arm digging force of 123.8 kN, operators can maintain productivity even in challenging marsh and dredging environments.
One of the major advantages of the HK400SD Swamp Excavator is its extended working range. The machine provides a maximum digging reach of up to 18.7 meters, allowing operators to access difficult locations without frequent repositioning.
This feature is particularly valuable for:
River dredging projects
Canal maintenance
Flood control operations
Lake restoration
Coastal engineering
Sediment removal
Environmental rehabilitation
The long reach design improves productivity and reduces operational downtime, helping contractors complete projects more efficiently.
The specially designed amphibious pontoon undercarriage provides exceptional flotation and stability. The pontoon system distributes machine weight over a larger surface area, reducing ground pressure to only 0.14 kg/cm².
This allows the HK400SD Marsh Excavator to operate safely on:
Swamps
Marshes
Peatlands
Mudflats
Wetlands
Soft riverbanks
Shallow water environments
The machine uses four DOOSAN travel motors to provide strong traction and mobility even in difficult terrain conditions.
For projects requiring operation in deeper water environments, the HK400SD can be equipped with optional side pontoons and spud systems.The optional deep-water package enables contractors to perform:
Deep-water dredging
Reservoir maintenance
Coastal protection projects
Harbor maintenance
Shoreline stabilization
Waterway construction
This flexibility makes the HK400SD a practical investment for contractors serving multiple industries.
The HK400SD is manufactured under strict quality management standards and is designed to meet the requirements of international buyers across Europe, the Middle East, Asia, Africa and South America.
With robust structural components, internationally recognized hydraulic components and dependable engine options, the machine offers long service life and reduced maintenance costs.
Production is completed within approximately 50 days after receipt of the down payment.
Payment Terms:
30% T/T deposit before production
70% balance before shipment
The HK400SD is an ideal choice for contractors, equipment rental companies, dredging specialists and government infrastructure projects requiring a dependable Swamp Buggy Excavator for long-term operation in difficult environments.
