Heavy Duty Swamp Excavator For River Dredging Projects

The HK200SD Swamp Excavator is a specialized 20-ton amphibious machine designed to operate efficiently in wetlands, marshes, riverbanks, and other soft terrain environments. Built for demanding construction conditions across Europe and the Middle East, this model combines strong hydraulic performance with exceptional flotation and stability.

Engine & Hydraulic Performance

Powered by the reliable Mitsubishi 4D34 turbocharged engine, the HK200SD delivers consistent output and fuel efficiency under continuous operation. The integration of a DOOSAN T5V63 hydraulic pump system ensures high responsiveness and precise control, making it ideal for dredging, excavation, and sediment removal projects. With a working pressure of up to 30 MPa, the machine maintains strong digging force even in challenging conditions.

Amphibious Undercarriage System

The excavator is equipped with a robust pontoon undercarriage system that provides excellent buoyancy and stability. The pontoons are engineered with reinforced structures to withstand harsh environments, while the optional hydraulic extendable undercarriage allows operators to adjust track width for improved balance during operation.

The four independent travel motors significantly enhance maneuverability, allowing the machine to move smoothly across muddy, swampy, or waterlogged surfaces. This design ensures continuous operation where conventional excavators cannot perform.

Structural Strength & Durability

The HK200SD features strengthened track shoes and chains, ensuring durability and reduced maintenance costs over time. The upper structure is compact yet robust, with optimized weight distribution to maintain low ground pressure. This prevents sinking and ensures stable performance in soft ground conditions.

Working Range & Efficiency

With a maximum digging reach of 10.8 meters and a digging depth exceeding 7 meters, the HK200SD is suitable for a wide range of applications, including river dredging, canal maintenance, wetland restoration, and coastal engineering projects. The standard 0.4 m³ bucket offers a balanced combination of capacity and efficiency.

Customization & Application Flexibility

To meet diverse project requirements, the HK200SD can be equipped with optional additional pontoons and spuds for deep water operations. This flexibility makes it a preferred choice for contractors handling complex marine and wetland construction tasks.
