40 Ton Amphibious Swamp Excavator HK400SD

The HEKING HK400SD swamp excavator is a specialized heavy-duty machine engineered to perform efficiently in challenging terrains such as wetlands, marshes, riverbanks, and coastal areas. Designed with a reinforced amphibious undercarriage and wide pontoons, this swamp excavator ensures exceptional stability and low ground pressure, making it ideal for soft and waterlogged ground conditions commonly found across Europe and the Middle East.

Powered by a high-performance Cummins C8.3 or Isuzu 6HK1 engine, the HK400SD delivers strong and reliable output with 183.9kW of power. This ensures consistent performance even in demanding applications such as dredging, canal maintenance, and environmental restoration. The engine is equipped with an inter-cooled turbo system, enhancing fuel efficiency and operational longevity while meeting international emission expectations.

The hydraulic system is built around dual Kawasaki variable plunger pumps, providing precise control and high efficiency. With a maximum working pressure of 32 MPa, operators benefit from smooth and responsive operation, even when handling heavy loads or working at extended reach distances. The machine's long boom and arm configuration allow a maximum digging reach of up to 18.7 meters, making it highly suitable for deep excavation and long-distance dredging tasks.

Mobility is a critical factor in swamp operations, and the HK400SD excels with its four DOOSAN travel motors and optimized track design. The system offers excellent traction and maneuverability, even in unstable terrain. Its low ground pressure of just 0.14 kg/cm² significantly reduces the risk of sinking, ensuring safe and efficient movement across soft ground.

The excavator is also designed with operational efficiency in mind. A large 560-liter fuel tank supports long working hours without frequent refueling, while the 250-liter hydraulic tank ensures consistent system performance. The modular design allows for easy maintenance, reducing downtime and operational costs—an important consideration for B2B buyers managing large-scale projects.

Additionally, the HK400SD offers flexible customization options, including additional pontoons and spud systems for deeper water applications. This adaptability makes it a preferred solution for contractors and project managers working on diverse infrastructure and environmental projects.

Overall, the HEKING swamp excavator combines durability, performance, and adaptability, making it a reliable investment for businesses seeking efficient solutions for complex terrain operations.
