The HEKING HK300SDA Amphibious Excavator is a heavy-duty long-reach excavating machine specifically designed for river dredging, wetland construction, flood control engineering, coastal infrastructure projects, and deep-water excavation applications. Built with a reinforced amphibious undercarriage and high-buoyancy pontoon system, this amphibious excavator delivers excellent flotation, strong stability, and reliable excavation performance in swamp, marshland, muddy terrain, shallow water, and low-bearing-capacity environments.
The HK300SDA is engineered for demanding operating conditions across Europe, the Middle East, Southeast Asia, Africa, and other regions where infrastructure and water management projects require reliable amphibious construction equipment. With its long-reach boom and arm system, the machine is capable of performing extended excavation operations while maintaining operational stability.
This model is widely used by dredging contractors, oil & gas pipeline companies, environmental engineering firms, government infrastructure agencies, and marine construction operators seeking a dependable solution for difficult terrain projects.
Long-reach boom design for deep dredging operations
High buoyancy pontoon structure improves stability in wetlands
Reinforced track chains increase durability in harsh environments
Four travel motors provide strong traction and maneuverability
Suitable for river dredging and flood control engineering
Low ground pressure minimizes sinking risk on soft terrain
High-quality hydraulic system ensures efficient excavation performance
Q345B steel pontoons improve structural reliability and lifespan
Optional deep-water accessories expand operating capability
The HK300SDA Amphibious Excavator is equipped with an 8600 mm boom and a 6260 mm arm, allowing a maximum digging reach of over 15.4 meters. This long-reach configuration is ideal for deep dredging, canal maintenance, riverbank reinforcement, and large-scale excavation projects where extended working distance is required.
Its advanced hydraulic system provides stable digging performance even during heavy-duty operations. The large working range allows operators to increase efficiency while reducing repositioning frequency during dredging and excavation work.
The machine is especially suitable for projects requiring excavation below water level or in difficult-to-access wetland environments.
The HK300SDA adopts a professional amphibious undercarriage designed for operation on extremely soft ground and shallow water surfaces. The reinforced pontoon structure provides high buoyancy and excellent weight distribution, enabling the excavator to move safely through marshes, wetlands, muddy terrain, and swamp environments.
The pontoons are manufactured using high-strength Q345B steel material for enhanced durability and corrosion resistance. Hull thickness specifications include 6 mm top plates, 6 mm side plates, and 8 mm bottom plates to improve structural strength during continuous heavy-duty operation.
The reinforced triple-chain track system with strengthened 40Cr rollers improves traction performance and reduces wear under abrasive conditions. Four independent travel motors provide excellent maneuverability and operational stability.
With a low ground pressure of only 0.14 kg/cm², the machine minimizes sinking risks and protects environmentally sensitive terrain.
The HK300SDA is powered by a Mitsubishi 4M50-TLC3J turbocharged diesel engine delivering stable output and excellent fuel efficiency for long working hours. Combined with dual Doosan T5V112 variable plunger hydraulic pumps, the excavator provides responsive hydraulic control and strong excavation force.
The PARKER AV280 hydraulic valve system improves operating precision and machine stability, while the Eaton swing motor ensures smooth rotation during dredging operations.
The hydraulic system is optimized for continuous heavy-duty use, making the excavator highly suitable for demanding industrial and infrastructure applications.
The HK300SDA Amphibious Excavator is commonly used for river dredging, sediment removal, canal cleaning, and flood prevention projects. Its long-reach excavation capability allows operators to perform deep digging and material handling directly from unstable or submerged terrain.
For flood control projects, the excavator supports embankment maintenance, drainage channel construction, and waterway rehabilitation. The machine's amphibious design allows efficient operation where conventional excavators cannot safely work.
Optional additional pontoons and spud systems can be installed for enhanced stability during deep-water operations.
The HK300SDA is also widely applied in coastal engineering and oil & gas pipeline installation projects. Its amphibious mobility allows construction work across tidal zones, wetlands, marshlands, and soft coastal terrain.
The machine can efficiently perform trench excavation, pipeline installation support, shoreline reinforcement, and marine infrastructure maintenance while minimizing terrain disturbance.
Its robust construction and corrosion-resistant design help ensure long-term operational reliability in harsh marine environments.
