The HEKING HK400SD Amphibious Excavator is a high-performance heavy-duty machine specifically engineered for demanding wetland, swamp, river dredging, and deep-water construction projects. Designed with strong floating capability, reinforced pontoons, and a reliable hydraulic system, this amphibious excavator delivers exceptional performance in terrains where conventional crawler excavators cannot safely operate.
With a 40-ton operating weight and extended digging reach of up to 18.7 meters, the HK400SD is ideal for large-scale dredging operations, coastal engineering projects, flood prevention work, mining tailing ponds, and oil & gas pipeline construction. The machine is widely used in environments with unstable soil conditions, marshlands, soft mud surfaces, shallow water zones, and saturated ground.
The HEKING HK400SD features a reinforced amphibious undercarriage system equipped with four DOOSAN travel motors, ensuring strong traction and stable mobility in difficult terrain conditions. Its large pontoon structure provides excellent buoyancy and low ground pressure, significantly reducing the risk of sinking during operation.
Designed for severe wetland and deep-water environments
Long reach digging capability for large-scale dredging projects
Strong floating stability with high-buoyancy pontoons
Reinforced undercarriage for harsh working conditions
Powerful hydraulic system ensures efficient excavation performance
Low ground pressure reduces sinking risk in soft terrain
Reliable Cummins and Kawasaki core components
Optional spud and pontoon systems for customized applications
Suitable for Europe, Middle East, and tropical project conditions
The HK400SD amphibious excavator is equipped with internationally recognized powertrain and hydraulic components to ensure reliable operation under continuous heavy-duty workloads.
Engine options include the Cummins C8.3 and Isuzu 6HK1 turbocharged diesel engines, delivering powerful output, excellent fuel efficiency, and long-term operational reliability. The inter-cooled turbo engine design provides stable performance even in high-temperature and humid environments commonly found in dredging and marine construction projects.
The hydraulic system utilizes a Kawasaki T5V140DT variable plunger pump combined with high-pressure hydraulic control systems. This configuration ensures:
Fast hydraulic response
Stable digging performance
High working efficiency
Reduced energy loss
Improved machine productivity
The advanced hydraulic system also supports long working hours in challenging jobsite conditions.
The pontoon undercarriage is one of the most critical components of an amphibious excavator. The HEKING HK400SD uses a heavy-duty floating pontoon structure designed for high durability and strong buoyancy performance.
Key undercarriage advantages include:
Reinforced track chains
Durable track shoes
Large buoyancy capacity
Stable floating balance
Low ground pressure operation
Excellent corrosion resistance
The machine can travel smoothly across wetlands, riverbanks, muddy surfaces, shallow lakes, and marsh environments. Optional additional pontoons and spud systems can further improve machine stability for deeper water operations.
The HEKING HK400SD is suitable for a wide range of industrial and infrastructure projects.
Efficiently removes sediment, mud, and debris from rivers, lakes, reservoirs, and canals to improve water flow and navigation capacity.
Provides stable excavation performance in swampy and environmentally sensitive wetland areas.
Supports drainage improvement, river widening, and flood prevention infrastructure projects.
Suitable for shoreline stabilization, coastal engineering, and shallow offshore operations.
Handles excavation and maintenance work in difficult muddy mining environments.
Supports pipeline trenching and construction projects in marshes and saturated terrain.
The HEKING HK400SD amphibious excavator is developed for international contractors, equipment rental companies, government infrastructure projects, and marine engineering businesses.
