The HEKING HK300SD floating excavator is a high-performance amphibious machine engineered to meet the rigorous demands of large-scale infrastructure and environmental projects across Europe and the Middle East. With its 30-ton operating weight and advanced hydraulic system, this equipment is specifically designed for applications such as river dredging, wetland construction, oil and gas pipeline installation, flood control, and coastal engineering.

Heavy-duty 30-ton floating excavator for dredging and wetland engineering projects

Powered by a robust Mitsubishi 4M50-TLC3J turbocharged engine, the HK300SD delivers consistent power output and fuel efficiency, ensuring reliable operation even in high-temperature and heavy-load conditions commonly found in Middle Eastern environments. The engine's strong torque performance supports continuous excavation tasks, making it ideal for long-duration projects.

The hydraulic system is equipped with dual high-capacity variable plunger pumps, providing a maximum working pressure of 32 MPa. This enables precise control and powerful digging capabilities, allowing operators to handle dense soil, silt, and sediment efficiently. The machine's large bucket capacity further enhances productivity, making it suitable for bulk material handling and dredging operations.

A key advantage of this floating excavator is its reinforced pontoon system. Designed for maximum buoyancy and stability, the pontoons allow the machine to operate effectively on waterlogged surfaces and soft terrain where conventional excavators would fail. The wide track gauge and optimized weight distribution ensure balance during operation, even in challenging conditions.

The HK300SD features a dual travel motor system that delivers strong traction force, enabling smooth movement across marshland, shallow water, and uneven ground. Its low ground pressure minimizes environmental impact, making it an excellent choice for eco-sensitive projects such as wetland restoration and flood management.

For projects requiring extended operational capabilities, the machine can be equipped with optional additional pontoons and spuds. This allows for stable performance in deeper water environments, expanding its usability across a wider range of engineering applications.

With a maximum digging reach of over 10 meters and efficient working range parameters, the HK300SD ensures flexibility and productivity on-site. Its durable construction, high-quality components from globally recognized brands, and optimized design make it a reliable investment for contractors seeking long-term operational efficiency.

Overall, the HEKING HK300SD floating excavator delivers a powerful combination of performance, durability, and adaptability, making it an ideal solution for demanding amphibious construction projects.
