The HK300SD Wetland Excavator is a professional amphibious excavator developed for demanding projects in wetlands, swamps, marshes, shallow water environments, riverbanks, and coastal areas. Designed specifically for contractors working in difficult terrain, the machine combines strong excavation performance with excellent flotation and stability.
As a specialized Wetland Construction Excavator, the HK300SD provides reliable operation where conventional crawler excavators face mobility limitations. Its large pontoon undercarriage distributes machine weight effectively, reducing ground pressure while maintaining productivity in soft ground conditions.
With a 30-ton operating weight, 10.18-meter digging reach, and powerful hydraulic system, the HK300SD is widely used in river dredging, flood control construction, wetland restoration, oil and gas pipeline projects, and coastal engineering works throughout Europe, the Middle East, Southeast Asia, and Africa.
The machine is engineered to improve productivity while minimizing site access challenges, making it an ideal solution for infrastructure contractors, environmental engineering companies, dredging specialists, and government agencies.
Wetland projects require equipment capable of operating safely on unstable surfaces. The HK300SD Marshland Excavator features a specially designed pontoon undercarriage that delivers exceptional flotation and stability.
Its wide flotation pontoons allow the excavator to travel efficiently across mud, marshland, peat, saturated soil, and shallow water. The low ground pressure of approximately 0.14 kg/cm² helps protect sensitive environments while reducing the risk of machine sinking.
Typical applications include:
River dredging projects
Wetland construction
Marshland reclamation
Flood prevention infrastructure
Canal maintenance
Coastal protection works
Oil and gas pipeline installation
Environmental restoration projects
Waterway maintenance operations
The machine's amphibious capability allows contractors to reach difficult work areas without the need for costly temporary access roads or additional support equipment.
The HK300SD is equipped with a Mitsubishi 4M50-TLC3J turbocharged diesel engine delivering 118 kW of power and 620 Nm of torque. This proven powertrain ensures dependable performance under continuous heavy-duty operation.
The hydraulic system incorporates a Doosan T5V112 variable plunger pump and PARKER AV280 control valve, providing responsive and efficient hydraulic control.
Benefits include:
Smooth excavation performance
High digging efficiency
Stable hydraulic output
Reduced fuel consumption
Reliable operation in harsh environments
With a maximum bucket digging force of 122.85 kN and arm digging force of 97.64 kN, the excavator can handle demanding dredging, excavation, and material handling applications.
The pontoon undercarriage is one of the key advantages of the HK300SD.
Features include:
Reinforced flotation pontoons
Heavy-duty track system
Three chain strands per side
Stable wide-track configuration
Excellent buoyancy performance
Enhanced durability in wet environments
For customers working in deeper water conditions, additional pontoons and spud systems can be installed to further expand operating capability.
This modular design provides greater flexibility for different project requirements and site conditions.
River dredging remains one of the primary applications for the HK300SD Wetland Excavator. The combination of strong digging performance and amphibious mobility enables operators to remove sediment, improve water flow, and maintain navigation channels efficiently.
In flood control projects, the excavator is used for:
Drainage channel excavation
River widening
Embankment reinforcement
Sediment removal
Water management infrastructure
The machine is also suitable for coastal engineering projects where access to soft shorelines and tidal areas is required.
Its versatility allows contractors to maximize equipment utilization across multiple project types throughout the year.
The HK300SD is manufactured under strict quality management standards and undergoes comprehensive testing before shipment.
The manufacturer maintains internationally recognized certifications, including:
ISO9001 Quality Management System
ISO14001 Environmental Management System
OHSAS18001 Occupational Health & Safety Management System
CE Certification for Wetland Hydraulic Excavators
