The HEKING HK400SD amphibious excavator is a professional heavy-duty machine engineered for challenging wetland, swamp, river dredging, and coastal engineering operations. Designed with a reinforced floating pontoon undercarriage and powerful hydraulic system, this 40 ton amphibious excavator delivers reliable performance in environments where standard crawler excavators cannot operate safely.
This amphibious excavator is widely used in river dredging projects, marshland construction, flood control work, lake maintenance, coastal reinforcement, environmental restoration, and deep water excavation. With its advanced floating structure and low ground pressure design, the HK400SD can travel efficiently across mud, wetlands, peat soil, shallow water, and unstable terrain.
The long reach working range allows operators to perform excavation and dredging operations from safer positions while improving efficiency in difficult environments. For contractors handling infrastructure development, water conservancy projects, or wetland restoration work, the HK400SD provides a dependable and cost-effective solution.
The floating pontoon system is one of the core advantages of the HK400SD swamp excavator. The machine adopts a heavy-duty amphibious pontoon structure engineered for stability and buoyancy during water-based operations. The reinforced pontoon design improves flotation performance while maintaining excellent machine balance during excavation.
The undercarriage uses three chain strands on each side combined with four travel motors to provide strong traction and stable movement across soft terrain. This configuration helps prevent sinking in marshes and muddy construction areas.
Compared with traditional excavators, the HK400SD wetland excavator significantly reduces ground pressure to only 0.14kg/cm², minimizing environmental impact and improving mobility on unstable surfaces.
For deep water working conditions, additional pontoons and spuds are available as optional configurations. These options improve operational stability and are especially suitable for lake dredging, coastal engineering, and waterway maintenance projects.
The HK400SD amphibious excavator is equipped with a high-performance hydraulic system designed for demanding excavation applications. The Kawasaki T5V140DT variable plunger pump delivers efficient hydraulic flow and stable pressure output, ensuring smooth machine operation under heavy workloads.
The hydraulic configuration provides excellent digging force and stable multi-function operation during dredging work. Combined with the powerful Cummins or Isuzu engine system, the machine achieves high productivity while maintaining fuel efficiency.
The hydraulic system supports continuous operation in difficult environments such as river sediment removal, swamp excavation, canal cleaning, and reservoir maintenance.
The fixed plunger slew motor and DOOSAN travel motors enhance machine responsiveness and control accuracy, allowing operators to work effectively even in narrow or unstable job sites.
The HK400SD long reach amphibious excavator is widely used in water conservancy and marine engineering industries. Its large working range and floating undercarriage make it suitable for multiple applications including:
River dredging projects
Flood prevention engineering
Wetland restoration work
Coastal reinforcement projects
Lake and reservoir maintenance
Marshland excavation
Environmental protection operations
Pipeline installation in wetlands
Canal cleaning and sediment removal
The machine's long reach boom improves operational coverage while reducing repositioning frequency. This helps contractors improve efficiency and reduce fuel consumption on large-scale projects.
Its durable structure and reliable hydraulic system also make it suitable for long-term rental projects and international contracting operations.
