The HK200SD Wetland Excavator is a professional-grade amphibious excavator developed for challenging terrain where conventional crawler excavators cannot operate efficiently. Designed specifically for wetland construction, marshland development, river dredging, environmental restoration, flood control, and coastal engineering projects, this machine combines excellent flotation performance with powerful excavation capabilities.
With an operating weight of 20 tons and a maximum digging reach of 10.78 meters, the HK200SD offers the ideal balance between working capacity and terrain adaptability. The machine is equipped with oversized pontoons that provide exceptional buoyancy, allowing safe and stable operation on soft ground, wetlands, swamps, marshes, riverbanks, and shallow water environments.
For contractors, government infrastructure agencies, dredging companies, and environmental engineering firms across Europe and the Middle East, the HK200SD delivers reliable productivity while reducing the risks associated with difficult ground conditions.
Wetland construction projects often involve unstable soil conditions where standard excavators experience excessive ground pressure and limited mobility. The HK200SD Wetland Construction Excavator addresses these challenges through its specialized pontoon undercarriage system.
The large flotation pontoons distribute machine weight across a significantly larger surface area, reducing ground pressure to approximately 0.14 kg/cm². This enables the machine to travel and work efficiently in marshes, peatlands, floodplains, wetlands, and coastal reclamation areas.
The machine's extendable undercarriage further improves stability during excavation tasks. Customers can select a manual extendable undercarriage as standard or choose the optional hydraulic extendable undercarriage for greater operational convenience.
This flexibility makes the HK200SD suitable for:
Wetland restoration projects
River dredging operations
Lake maintenance works
Flood control construction
Marshland reclamation
Environmental protection projects
Pipeline installation in soft ground
Coastal engineering works
Waterway maintenance programs
The HK200SD Marshland Excavator is powered by the proven Mitsubishi 4D34 turbocharged diesel engine. Producing 70 kW of power and 370 Nm of torque, the engine provides dependable performance under demanding site conditions.
The hydraulic system incorporates a DOOSAN T5V63 variable displacement pump and PARKER AV170 control valve, ensuring precise hydraulic control and efficient power delivery.
Key hydraulic benefits include:
Smooth operation during dredging tasks
Fast response times
Consistent digging performance
Reduced fuel consumption
Reliable operation in harsh environments
The machine delivers a maximum digging depth of 7.03 meters and a dumping height exceeding 9 meters, allowing operators to complete demanding excavation and material handling tasks efficiently.
One of the most important advantages of the HK200SD is its specialized amphibious undercarriage design.
The system features:
Four independent travel motors
Strengthened track chains
Reinforced track shoes
Large buoyancy pontoons
Extendable track gauge
Enhanced stability structure
The four-motor travel system significantly improves mobility in muddy, submerged, and unstable conditions. Reinforced track components increase service life and reduce maintenance requirements, helping contractors lower operating costs over the machine's lifecycle.
For deep-water applications, additional pontoons and spud systems can be installed to expand operational capabilities.
The HK200SD Wetland Excavator is widely used in projects requiring safe access to soft ground and shallow water areas.
Typical applications include:
River dredging operations require machines capable of maintaining stability while removing sediment and restoring waterway capacity. The HK200SD provides sufficient reach and digging force to perform these tasks effectively.
Environmental restoration projects benefit from the machine's low ground pressure characteristics, minimizing disturbance to sensitive ecosystems.
Coastal protection programs utilize the excavator for shoreline maintenance, erosion control, and drainage improvement.
Infrastructure contractors use the machine for installing utilities, drainage channels, and flood control structures in challenging terrain.
Its versatility makes it a valuable asset for both public and private sector projects.
Manufactured by HEKING, the HK200SD is built using strict production processes and quality management standards.
The company maintains certifications including:
ISO9001 Quality Management System
ISO14001 Environmental Management System
OHSAS18001 Occupational Health & Safety System
CE Certification for Wetland Hydraulic Excavators
Each machine undergoes comprehensive inspection before shipment to ensure dependable field performance.
Production is completed within approximately 20 days after receipt of the down payment, helping international customers reduce project lead times.
