The HK200SD amphibious pontoon excavator is engineered for challenging wetland, swamp, marsh, and shallow water environments where standard excavators cannot operate efficiently. Designed for contractors involved in river dredging, flood control, environmental restoration, coastal engineering, and soft terrain construction, this 20-ton machine combines excellent flotation performance with stable excavation capability.
Equipped with a reinforced amphibious pontoon undercarriage, the HK200SD offers superior buoyancy and low ground pressure, allowing the machine to travel smoothly across mud, wetlands, and unstable surfaces. The large pontoon structure helps maintain stability during excavation while reducing the risk of sinking in difficult terrain.
This amphibious excavator is especially suitable for contractors and project operators in Europe, the Middle East, Southeast Asia, and coastal regions where wetland construction and dredging operations require durable and reliable equipment.
The HK200SD uses a DOOSAN T5V63 variable plunger hydraulic pump combined with PARKER AV170 valves to ensure responsive hydraulic control and stable digging performance. The hydraulic system provides strong operating force while maintaining efficiency during long working hours.
The excavator delivers a maximum bucket digging force of 725kN and an arm digging force of 51kN, making it suitable for demanding excavation and dredging tasks. Whether working on riverbank reinforcement, drainage channel maintenance, or pond excavation, the machine maintains stable output and smooth operation.
The machine also features a DOOSAN swing motor and four independent DOOSAN travel motors that improve traction and maneuverability in swamp and floating conditions.
One of the key advantages of the HK200SD amphibious pontoon excavator is its advanced travel system. The machine is equipped with four travel motors that distribute power effectively across the undercarriage, ensuring reliable movement in muddy or submerged conditions.
The reinforced track shoes and chains are specifically designed for harsh wetland environments. This configuration increases durability and minimizes maintenance costs during long-term dredging and marsh operations.
The extendable undercarriage is available in manual or hydraulic versions, allowing operators to adjust the working width according to site conditions. The wider track gauge significantly improves machine stability during excavation on soft ground.
The HK200SD is widely used in:
River dredging projects
Wetland restoration operations
Swamp excavation work
Flood prevention engineering
Coastal maintenance projects
Fish pond and lake cleaning
Marshland infrastructure construction
Waterway maintenance
The optional additional pontoon and spud system allow the excavator to operate in deeper water conditions, improving adaptability for specialized dredging projects.
Its maximum digging depth of 7033mm and dumping height of 9057mm make it suitable for medium and large-scale excavation tasks.
The excavator is powered by a Mitsubishi 4D34 inter-cooled turbo diesel engine with 70kW output at 2200rpm. This engine is known for durability, stable fuel consumption, and easy maintenance, making it ideal for international B2B customers seeking dependable construction equipment.
The hydraulic and engine systems are optimized to provide continuous performance during long working shifts in difficult environmental conditions.
The large 300L fuel tank supports extended operations in remote project areas where frequent refueling may not be practical.
The HK200SD amphibious pontoon excavator is manufactured for global export requirements and supports international project contractors, equipment dealers, and engineering companies.
Production time is generally within 20 days after receipt of down payment, helping buyers meet urgent project schedules. Payment terms support international transactions through T/T with 30% deposit and 70% balance before delivery.
HEKING also provides technical support, optional configurations, and customized solutions according to project requirements.
