The HK200SD Swamp Excavator is a professional-grade swamp buggy excavator developed for operation in challenging environments where conventional crawler excavators cannot work efficiently. Designed specifically for wetlands, marshlands, riverbanks, ponds, lakes, coastal zones, and soft ground construction sites, the machine combines excellent flotation capability with powerful excavation performance.
With an operating weight of 20 tons and a reinforced amphibious pontoon undercarriage, the HK200SD provides outstanding stability across unstable terrain. Its large buoyancy design minimizes ground pressure while allowing operators to travel safely through waterlogged areas, muddy conditions, and environmentally sensitive project zones.
The machine is widely used in river dredging, wetland restoration, environmental rehabilitation, flood control projects, canal maintenance, shoreline stabilization, oil and gas access road construction, and infrastructure development in marsh environments.
For contractors seeking a reliable marsh excavator capable of maintaining productivity where traditional equipment becomes immobilized, the HK200SD provides a proven solution.
Many construction projects take place in environments where ordinary excavators face severe mobility limitations. Wetlands, swamps, marshes, lagoons, estuaries, riverbanks, and shallow water areas require specialized equipment capable of floating and traveling over unstable terrain.
The HK200SD swamp buggy excavator utilizes large pontoons and a low ground pressure design of only 0.14 kg/cm². This enables the machine to move across soft surfaces while reducing environmental disturbance.
Typical applications include:
River dredging projects
Canal maintenance
Wetland restoration
Environmental protection projects
Flood control operations
Marshland infrastructure development
Coastal engineering projects
Pipeline installation access
Waterway construction
Sediment removal operations
Its maximum digging depth of 7.03 meters and dumping height of over 9 meters allow contractors to perform efficient excavation and material handling tasks in difficult working conditions.
The HK200SD is equipped with a DOOSAN T5V63 variable plunger hydraulic pump designed to provide smooth operation and strong digging performance.
Combined with the PARKER AV170 hydraulic valve system, operators benefit from responsive controls and precise movement. The hydraulic system delivers a working pressure of 30 MPa, supporting demanding excavation applications.
Performance highlights include:
Bucket digging force of 72.5 kN
Arm digging force of 51 kN
Slewing speed of 13.6 rpm
Maximum travel speed of 3 km/h
Gradeability up to 35°
These specifications allow the machine to maintain productivity even in difficult ground conditions.
Unlike many standard amphibious excavators, the HK200SD incorporates four independent travel motors.
This configuration improves traction, stability, and maneuverability in soft terrain. The four-motor system distributes power more evenly across the pontoon structure, helping maintain movement through mud, marshes, and shallow water.
Benefits include:
Enhanced traction performance
Improved maneuverability
Better load distribution
Increased reliability
Reduced risk of sinking in soft ground
The strengthened track chains and reinforced track shoes further improve durability under harsh working conditions.
The amphibious pontoon system is one of the most critical components of a swamp excavator.
The HK200SD features large-dimension pontoons measuring over 9.2 meters in length. These pontoons generate substantial flotation while maintaining machine stability.
Key advantages include:
Excellent flotation capacity
Improved working stability
Reduced ground pressure
Safe operation in shallow water
Longer service life
For deep-water applications, customers may select optional side pontoons and spud systems to further enhance stability and working capability.
The HK200SD is engineered to meet the requirements of professional contractors across Europe, the Middle East, Africa, Southeast Asia, and South America.
The machine incorporates internationally recognized components, including:
Mitsubishi diesel engine
DOOSAN hydraulic pump
PARKER hydraulic valve
DOOSAN travel motors
This component selection simplifies maintenance and parts sourcing while ensuring reliable operation throughout the machine's service life.
Production is completed within approximately 20 days after receipt of the down payment, helping contractors reduce project waiting times.
