The HK300SDA wetland excavator is a professional amphibious excavation machine engineered for demanding environments including wetlands, marshes, swamps, riverbanks, shallow lakes, and coastal engineering areas. Designed with a long reach boom and reinforced amphibious undercarriage, this machine provides reliable excavation performance while maintaining excellent flotation and low ground pressure.
Built for contractors handling dredging, environmental restoration, flood control, and pipeline infrastructure projects, the HK300SDA combines powerful hydraulic performance with enhanced stability on soft terrain. Its four-motor travel system ensures strong traction and maneuverability in muddy and waterlogged ground conditions where conventional crawler excavators cannot operate efficiently.
The machine adopts high-strength Q345B steel pontoons with optimized buoyancy design. The hull structure uses 6mm top plate thickness, 6mm side plate thickness, and 8mm bottom plate thickness to withstand challenging wetland operations and prolonged water exposure. Reinforced track shoes and 40Cr roller chains further improve durability during heavy-duty dredging and swamp construction projects.
The HK300SDA wetland excavator is specifically developed for projects requiring extended working reach and stable floating performance. With a maximum digging reach of 15.4 meters and digging depth exceeding 10.8 meters, the machine is highly suitable for river dredging, pond cleaning, silt removal, canal maintenance, and deep-water excavation.
Its large pontoon dimensions and wide track gauge improve machine balance during long-arm operation. The amphibious undercarriage distributes machine weight effectively across soft surfaces, minimizing sinkage and ensuring safe operation in wetlands and marsh environments.
This long reach wetland excavator is commonly used for:
River dredging projects
Wetland restoration works
Flood prevention construction
Oil & gas pipeline installations
Coastal engineering operations
Lake cleaning and sediment removal
Marshland infrastructure development
Environmental protection projects
The optional additional pontoon and spud system allows the excavator to operate in deeper water conditions while maintaining working stability.
The HK300SDA uses a Mitsubishi 4M50-TLC3J turbocharged diesel engine delivering 118kW at 2000rpm. The engine provides reliable power output and fuel efficiency for continuous heavy-duty applications. Combined with the Doosan T5V112 hydraulic pump and PARKER AV280 valve system, the excavator achieves smooth hydraulic response and high excavation efficiency.
The advanced hydraulic configuration supports precise boom movement during dredging and long reach excavation tasks. Operators benefit from stable control performance even when working at maximum reach distances.
The Eaton swing motor and DOOSAN TM40VC travel motors ensure reliable mobility and turning capability in difficult terrain conditions. The four-motor travel design significantly improves traction on soft mud and floating surfaces compared with traditional two-motor systems.
Heavy-Duty Amphibious Undercarriage
One of the key strengths of the HK300SDA wetland excavator is its reinforced amphibious undercarriage. The machine is equipped with:
Four independent travel motors
Strengthened track shoes and chains
Large buoyancy pontoons
Reinforced steel structure
Heavy-duty floating chassis
The pontoons are manufactured using durable Q345B material to improve corrosion resistance and structural integrity. This undercarriage design enables the machine to operate effectively in unstable ground conditions while maintaining low ground pressure.
Compared with conventional excavators, the HK300SDA offers superior flotation and mobility in swamps, marshes, wetlands, and shallow water environments.
The HK300SDA is designed for international B2B buyers seeking durable wetland excavation equipment for long-term infrastructure projects. The excavator is suitable for contractors, dredging companies, government water management projects, and oil & gas engineering firms across Europe, the Middle East, Southeast Asia, and Africa.
The machine is manufactured under strict quality management systems and supported by professional production capabilities. Delivery time is typically within 45 days after receipt of down payment.
Payment terms:
30% T/T down payment
70% balance before delivery
For overseas customers, optional customization and configuration upgrades are available based on project requirements.
