The HEKING HK300SD amphibious excavator is a 30-ton class heavy-duty solution designed for large-scale water engineering, dredging, and soft-ground construction projects. Built to meet the operational and procurement standards of professional buyers in Europe and the Middle East, the HK300SD delivers high output performance, structural stability, and long-term operational reliability in challenging aquatic environments.
This amphibious excavator is equipped with a high-buoyancy steel pontoon undercarriage, allowing it to operate efficiently on rivers, lakes, wetlands, coastal zones, and reclaimed land. With an average ground pressure of approximately 0.14 kg/cm², the HK300SD minimizes soil disturbance and maintains flotation where standard crawler excavators are unable to work. The pontoon dimensions of 8.3 meters in length and 1.8 meters in width provide a stable working platform even during high-load excavation.
Power is supplied by internationally recognized diesel engines, including the Isuzu 6BG1TRP-03 and Mitsubishi 4M50 turbocharged engines, delivering up to 118 kW of rated power. These engines are widely used across global construction markets, ensuring reliable performance, fuel efficiency, and ease of maintenance. The powertrain is matched with a Doosan T5V112 dual variable plunger hydraulic pump and a PARKER AV280 control valve, producing a working pressure of up to 32 MPa for smooth and precise operation.
The HK300SD offers a maximum digging reach of approximately 10 meters and supports a standard bucket capacity of up to 0.9 m³, making it suitable for high-volume dredging, sediment removal, and material handling. Strong bucket and arm digging forces enable the machine to perform efficiently in compacted silt, clay, and submerged soil conditions.
Travel and maneuverability are handled by DOOSAN TM60VC travel motors, designed for stable movement across floating pontoons and soft terrain. The slew system operates at a controlled speed of 11 rpm, allowing precise positioning during excavation and loading operations. Reinforced chain strands and undercarriage components enhance durability in long-term water-based use.
For projects requiring deeper water operation or higher current resistance, the HK300SD can be equipped with additional pontoons and a spud anchoring system. This optional setup improves stability and allows the excavator to maintain accurate working positions during dredging or excavation tasks.
From a commercial perspective, the HK300SD is optimized for export-oriented procurement. Standard payment terms include 30% T/T down payment and 70% balance before delivery, with a production lead time of approximately 40 days after deposit receipt. This makes the machine suitable for infrastructure contractors, rental fleets, and government-backed water management projects operating on strict schedules.
