The HK300SD Swamp Excavator is a professional amphibious excavation machine developed for challenging environments where conventional crawler excavators cannot operate efficiently. Designed specifically for river dredging, marshland construction, flood control, oil and gas pipeline installation, and coastal engineering projects, this machine combines high flotation performance with powerful hydraulic excavation capabilities.
As a heavy-duty Swamp Buggy Excavator, the HK300SD utilizes a specially engineered pontoon undercarriage system that distributes machine weight over a larger surface area. This significantly reduces ground pressure and enables stable operation on soft soils, wetlands, marshes, shallow water areas, riverbanks, and muddy construction sites.
For contractors, dredging companies, government infrastructure departments, and environmental engineering firms throughout Europe, the Middle East, Southeast Asia, Africa, and South America, the HK300SD offers a reliable solution for projects requiring superior mobility in difficult terrain.
Many construction and dredging projects take place in locations where traditional excavators struggle due to poor ground conditions. Swamps, marshlands, riverbanks, mudflats, coastal wetlands, and flood-prone zones require specialized equipment capable of maintaining stability while delivering strong digging performance.
The HK300SD Marsh Excavator addresses these challenges through its robust amphibious design. With a machine operating weight of 30 tons and large flotation pontoons measuring 8.285 meters in length and 1.8 meters in width, the excavator provides exceptional buoyancy and stability.
Its low ground pressure of only 0.14 kg/cm² helps prevent sinking in soft ground while reducing environmental impact on sensitive wetlands. This makes the machine particularly suitable for environmental restoration projects and protected ecological zones.
The HK300SD is powered by a Mitsubishi 4M50-TLC3J turbocharged diesel engine producing 118 kW of power and 620 N·m of torque. This engine delivers reliable performance even during demanding dredging and excavation operations.
The hydraulic system features dual Doosan T5V112 variable displacement pumps with a maximum displacement of 2 × 112 cm³/rev and a working pressure of 32 MPa. This combination ensures smooth machine control, strong breakout force, and efficient operation in tough working conditions.
Key hydraulic performance advantages include:
Bucket digging force of 122.85 kN
Arm digging force of 97.64 kN
Stable hydraulic flow for continuous dredging
Excellent lifting and material handling capability
Precise control for environmental projects
These features allow operators to complete excavation tasks more efficiently while maintaining accuracy and productivity.
The HK300SD swamp excavator is widely used for river dredging projects, sediment removal, channel deepening, and waterway maintenance. Its long reach and stable pontoon design allow operators to work directly from waterlogged areas without requiring extensive temporary access roads.
For wetland restoration, ecological rehabilitation, and environmental engineering projects, the machine minimizes ground disturbance while maintaining excellent operational efficiency.
Pipeline installation frequently crosses marshes, wetlands, and coastal regions. The HK300SD provides reliable access and excavation capability in areas where conventional equipment cannot travel safely.
Government agencies and contractors use the machine for flood prevention infrastructure, drainage channel maintenance, embankment construction, and emergency water management operations.
The machine performs effectively in tidal zones, estuary developments, shoreline stabilization, and coastal infrastructure construction.
The advanced amphibious undercarriage system is one of the most important components of the HK300SD.
Features include:
High-buoyancy steel pontoons
Reinforced track chains
Heavy-duty track shoes
Optimized flotation design
Excellent lateral stability
Reliable propulsion in shallow water
Corrosion-resistant structure
Easy maintenance access
Long service life
For deep-water projects, optional side pontoons and spud systems can be installed to enhance flotation and operational stability.
The HK300SD is manufactured under strict quality control standards and is supported by modern production facilities, professional engineering teams, and international export experience.
The machine benefits from:
ISO9001 quality management systems
CE-certified amphibious excavator manufacturing
Proven project applications worldwide
Comprehensive spare parts support
