The HEKING HK300SDA swamp excavator is a professional long reach amphibious excavator developed for demanding environments where conventional excavators cannot operate efficiently. Designed with a reinforced amphibious undercarriage and high buoyancy pontoon structure, this machine performs reliably in wetlands, marshes, muddy riverbanks, shallow water areas, and coastal construction zones.
With a total operating weight of 36 tons and a maximum digging reach of over 15 meters, the HK300SDA is ideal for large-scale river dredging, flood control engineering, environmental restoration, and deep-water excavation projects. The machine combines stability, flotation capability, and hydraulic performance to meet the operational demands of contractors across Europe, the Middle East, Southeast Asia, and Africa.
This swamp excavator is widely used in projects where low ground pressure and superior mobility are critical. Its reinforced pontoon system distributes machine weight effectively, allowing stable operation on extremely soft terrain while minimizing sinking risks.
The HK300SDA features an 8600mm boom and a 6260mm arm, delivering exceptional working range for deep dredging and long-distance excavation. The maximum digging reach of 15426mm and digging depth exceeding 10 meters make this machine highly suitable for river maintenance, canal cleaning, sediment removal, and shoreline reinforcement projects.
Compared with standard excavators, this long reach swamp excavator significantly improves operational efficiency in difficult access areas. Operators can complete excavation work from safer positions while reducing the need for repositioning during dredging operations.
The 0.5m³ bucket capacity is optimized for wetland excavation and sludge removal, ensuring efficient material handling without compromising machine stability.
The amphibious undercarriage is one of the core advantages of the HK300SDA. The machine uses four travel motors for stronger traction and enhanced maneuverability in soft ground conditions. The reinforced track shoes and 40Cr chain rollers improve durability during continuous operation in abrasive mud and water environments.
Manufactured from high-strength Q345B steel, the pontoons are engineered for long-term durability and corrosion resistance. The hull structure includes:
Top plate thickness: 6mm
Side plate thickness: 6mm
Bottom plate thickness: 8mm
The large buoyancy design enhances flotation performance and provides greater operational safety during deep-water projects.
For contractors handling more challenging water conditions, optional additional pontoons and spuds are available to further improve stability and anchoring capability.
The HK300SDA swamp excavator is equipped with a Mitsubishi 4M50-TLC3J inter-cooled turbocharged engine delivering 118kW at 2000rpm. This engine configuration provides stable power output, fuel efficiency, and dependable performance for heavy-duty operations.
The hydraulic system includes:
Doosan T5V112 variable plunger pump
PARKER AV280 control valve
Eaton swing motor
DOOSAN TM40VC travel motors
This combination ensures smooth hydraulic response, precise machine control, and reliable operation under continuous heavy workloads.
The hydraulic working pressure of 32Mpa supports powerful digging force and stable attachment performance, especially during dredging and excavation in dense sediment conditions.
The HK300SDA is suitable for a wide range of specialized engineering applications, including:
River dredging projects
Wetland development
Flood prevention infrastructure
Coastal engineering
Marshland excavation
Environmental restoration
Oil and gas pipeline projects
Lake maintenance operations
Water conservancy construction
Its low ground pressure allows operation in environmentally sensitive areas while minimizing terrain damage.
HEKING manufactures swamp excavators for global infrastructure and environmental engineering contractors. The HK300SDA is designed to meet the procurement requirements of overseas dealers, project contractors, rental companies, and government engineering organizations.
The machine supports stable export logistics and professional manufacturing standards. Production is completed within 45 days after receipt of the down payment.
