The HK300SD wetland excavator is a professional amphibious excavator engineered for challenging terrain applications including river dredging, swamp operations, wetland construction, flood prevention projects, and coastal engineering. Designed for contractors and infrastructure companies operating in soft soil and shallow water environments, this machine combines strong flotation performance with reliable hydraulic power.
This 30-ton wetland excavator is equipped with reinforced pontoons and a low ground pressure structure, allowing stable movement across muddy terrain, marshland, and waterlogged construction sites. The machine is suitable for projects where standard crawler excavators cannot operate efficiently.
With a maximum digging reach exceeding 10 meters and a durable hydraulic system, the HK300SD can handle dredging, sediment removal, canal cleaning, embankment reinforcement, and environmental restoration work. The combination of powerful digging force and excellent flotation capacity makes it highly suitable for large-scale infrastructure projects in Europe, the Middle East, Southeast Asia, and coastal regions worldwide.
River Dredging Operations
The HK300SD wetland excavator is widely used for river dredging and waterway maintenance projects. Its amphibious undercarriage allows operators to work directly in shallow water and muddy riverbanks without additional floating platforms. Contractors can improve operational efficiency while reducing transportation and setup costs.
Wetland Construction Projects
For wetland development and ecological restoration, the machine provides low ground pressure and stable movement across sensitive terrain. The large buoyancy pontoons reduce environmental impact while maintaining strong operational capability.
Flood Control Engineering
Flood control authorities and municipal contractors use this wetland excavator for drainage improvement, sediment clearing, and emergency waterway maintenance. The machine can access flooded areas where traditional excavators may become trapped.
Oil & Gas Pipeline Projects
Pipeline construction in swamp regions requires specialized equipment capable of operating safely on unstable ground. The HK300SD provides reliable mobility and digging performance for trenching and site preparation in difficult terrain.
Coastal Engineering and Shoreline Maintenance
The reinforced amphibious structure makes the HK300SD suitable for coastal engineering work, shoreline reinforcement, and marine construction support operations. Optional deep-water pontoons and spud systems are available for demanding marine applications.
High buoyancy pontoon structure for swamp and shallow water work
Low ground pressure reduces sinking risk in soft terrain
Reliable Mitsubishi turbocharged engine for continuous operation
Strong hydraulic digging force for dredging efficiency
Reinforced pontoon design improves machine stability
Suitable for river, marsh, coastal, and flood control projects
Optional deep-water spud system available
Easy transportation and maintenance structure
Designed for long operating hours in harsh environments
The HK300SD wetland excavator adopts a Mitsubishi 4M50-TLC3J turbocharged diesel engine delivering stable output for demanding dredging applications. Combined with the Doosan T5V112 hydraulic pump and PARKER AV280 valve system, the machine provides smooth hydraulic response and reliable multi-function control.
The hydraulic system operates at a maximum working pressure of 32MPa, ensuring powerful excavation capability even in dense sediment and heavy clay conditions. The dual travel motor system enhances traction and maneuverability in wetlands and swamp areas.
The excavator also features strong bucket breakout force and arm digging force, supporting efficient excavation in river maintenance, drainage construction, and environmental protection projects.
The HK300SD features reinforced amphibious pontoons specifically designed for wetland and dredging environments. The pontoon dimensions provide excellent flotation and operational balance during excavation.
The machine's wide track gauge and stable undercarriage design improve operator confidence when working in unstable terrain conditions. Its low ground pressure minimizes soil disturbance and supports operation in environmentally sensitive areas.
Optional configurations such as additional pontoons and spud systems can be customized according to project depth and operational requirements.
