The HEKING HK400SD swamp excavator is a professional amphibious excavator engineered for demanding wetland construction and dredging environments. Designed for contractors operating in marshes, shallow water, muddy ground, and unstable terrain, this heavy-duty machine combines high flotation performance with powerful hydraulic excavation capability.
With a total operating weight of 40 tons, the HK400SD provides exceptional stability during excavation, dredging, and flood control work. The machine is widely used in river management projects, wetland restoration, coastal engineering, mining tailing ponds, lake dredging, and environmental construction operations across Europe, the Middle East, Southeast Asia, and Africa.
Its reinforced amphibious undercarriage allows the excavator to travel efficiently over soft soil, peatland, swamp surfaces, and shallow water where standard crawler excavators cannot operate safely.
The HK400SD swamp excavator features a reinforced pontoon undercarriage specifically designed for high buoyancy and low ground pressure performance. The wide pontoons distribute the machine weight evenly, helping reduce sinking risks in unstable terrain.
The amphibious platform includes:
Heavy-duty pontoon structure
Three-chain track design
Four independent travel motors
High flotation performance
Stable movement on muddy terrain
Enhanced corrosion resistance for water environments
The pontoons are manufactured using durable steel structures designed for long-term operation in wet and corrosive environments. For customers working in deeper water conditions, additional pontoons and spud systems are available as optional configurations.
This design makes the HK400SD suitable for:
River dredging
Swamp excavation
Canal maintenance
Wetland infrastructure projects
Coastal engineering
Flood prevention work
Mining pond maintenance
Environmental restoration projects
The HK400SD amphibious excavator is equipped with a high-performance hydraulic system that delivers strong digging power and reliable operating efficiency.
Powered by a Cummins C8.3 or Isuzu 6HK1 engine, the excavator generates up to 183.9kW at 2200rpm, providing consistent output for demanding excavation tasks.
The hydraulic system includes a Kawasaki T5V140DT variable plunger pump, ensuring smooth hydraulic response, high operational efficiency, and stable power delivery during continuous work cycles.
The machine achieves:
Maximum digging depth of 7396mm
Maximum digging height of 12127mm
Maximum dumping height of 9018mm
Bucket digging force of 135kN
Arm digging force of 123.8kN
These specifications make the HK400SD suitable for large-scale dredging and heavy excavation applications requiring extended working reach and high productivity.
The HK400SD swamp excavator is designed with durability and easy maintenance in mind. Major hydraulic and engine components are sourced from internationally recognized suppliers to improve machine reliability and simplify aftermarket servicing.
Core components include:
Cummins / Isuzu engine
Kawasaki hydraulic pump
DOOSAN travel motor
SUNJIN swing motor
The robust steel structure and reinforced amphibious chassis help reduce downtime in harsh working conditions. The excavator is also designed for easy transportation and field maintenance, supporting efficient project deployment.
HEKING provides manufacturing support, quality inspection, and export experience for international customers seeking reliable amphibious excavation equipment.
Production time is generally within 50 days after receipt of down payment.
Payment terms:
30% T/T down payment and 70% balance before delivery.
The HK400SD is widely used for demanding engineering projects where conventional excavators face mobility limitations.
Typical applications include:
River dredging operations
Swamp and marsh excavation
Wetland construction
Flood control engineering
Coastal reinforcement projects
Lake maintenance dredging
Mining sediment removal
Oil and gas field access work
Environmental protection projects
Canal and waterway maintenance
Its combination of flotation capability, hydraulic power, and long operational reach makes it a preferred solution for contractors handling difficult terrain conditions.
