The HK300SDA Swamp Buggy Excavator is engineered specifically for contractors working in wetlands, marshes, swamps, riverbanks, coastal zones, ponds, lagoons, and other soft-ground environments where conventional excavators cannot operate safely.
Built on a reinforced amphibious undercarriage, the machine combines powerful excavation performance with exceptional flotation capability. Its large pontoons distribute machine weight over a broad surface area, significantly reducing ground pressure and preventing sinking in unstable terrain.
Designed for professional dredging contractors, environmental restoration companies, civil engineering firms, and government infrastructure projects, the HK300SDA provides reliable productivity in locations that are difficult or impossible to access using standard crawler excavators.
Wetland and marshland construction projects often present severe operational challenges. Soft soil, standing water, unstable riverbanks, and deep mud can cause traditional machines to become immobilized, resulting in costly delays and increased project risks.
The HK300SDA Marsh Excavator solves these challenges through its specialized amphibious design.
Key structural advantages include:
Reinforced pontoon chassis
Large buoyancy system
Four independent travel motors
Heavy-duty track chains
Strengthened 40Cr rollers
Corrosion-resistant steel structure
Wide working platform
Excellent flotation stability
These features allow operators to work confidently across marshes, bogs, wetlands, tidal flats, and shallow water environments.
One of the most important advantages of the HK300SDA is its long-reach excavation capability.
Featuring an 8.6-meter boom and a 6.26-meter arm, the machine achieves a maximum digging reach of 15.4 meters and a digging depth exceeding 10.8 meters.
This extended working range allows contractors to:
Perform river dredging from safe positions
Clean canals and drainage systems
Maintain reservoirs and lakes
Restore wetlands
Remove accumulated sediment
Execute flood control projects
Conduct shoreline stabilization work
The long reach minimizes machine repositioning, improving productivity and reducing project costs.
The HK300SDA utilizes internationally recognized hydraulic components to ensure long-term reliability.
Core hydraulic components include:
Mitsubishi 4M50-TLC3J Engine
Doosan T5V112 Hydraulic Pump
PARKER AV280 Main Valve
Eaton Swing Motor
DOOSAN Travel Motors
The hydraulic system delivers:
Maximum working pressure of 32 MPa
High digging force
Smooth operation
Fast response times
Efficient fuel utilization
Reduced maintenance requirements
This configuration ensures stable performance during continuous dredging and excavation operations.
The amphibious undercarriage is one of the most critical elements of any swamp excavator.
The HK300SDA features:
Q345B structural steel construction
Hull top plate thickness: 6 mm
Side plate thickness: 6 mm
Bottom plate thickness: 8 mm
Three chain strands per side
Four travel motors
Large-volume flotation pontoons
This robust structure provides excellent durability when operating in abrasive mud, wetland vegetation, sand, and shallow water.
For deep-water projects, customers may select optional additional pontoons and spud systems to enhance stability and operational capability.
The HK300SDA Swamp Buggy Excavator is widely used in:
Removal of sediment, mud, and debris from waterways.
Habitat rehabilitation and environmental protection projects.
Construction and maintenance of coastal infrastructure.
Channel expansion and drainage improvement projects.
Infrastructure construction in soft-ground environments.
Safe operation in waterlogged industrial sites.
