Its variable plunger hydraulic system coupled with premium components like Kawasaki valves and pumps, and DOOSAN travel motors, provides smooth operation, precise digging, and strong lifting capacity.
With a standard bucket capacity of 1.3 m³, a boom length of 6,733 mm, and an arm length of 4,520 mm, the HK400SD reaches maximum digging depths of up to 7,396 mm and dumping heights of 9,018 mm. Its low ground pressure of 0.14 kg/cm² allows operation on sensitive wetlands, minimizing terrain damage while maintaining stability.
The machine features dual pontoons with a length of 11,400 mm and width of 1,800 mm, ensuring excellent buoyancy and flotation. Its slew speed of 9 rpm and travel speed of 2.1 km/h (high) enable precise maneuvering in water or swampy conditions. The 560 L fuel tank and 250 L hydraulic tank allow extended working hours without interruptions.
HEKING HK400SD is optimized for wholesale buyers and contractors in Europe & the Middle East, offering durable construction, low maintenance, and compliance with international standards. The excavator's design emphasizes modular parts for ease of replacement and repair, making it ideal for fleets used in ongoing wetland reclamation, irrigation, river dredging, and waterway maintenance.
Its advantages include strong digging forces (bucket 135 kN, arm 123.8 kN), wide operational range, and stability in challenging terrain, making it suitable for a variety of heavy-duty applications. B2B buyers can confidently procure multiple units for projects requiring high reliability and efficiency in wetland and aquatic construction.
Whether for infrastructure contractors, environmental engineers, or dredging companies, the HEKING HK400SD offers the performance, durability, and adaptability essential for large-scale amphibious operations.
