The HEKING HK300SDA amphibious excavator is a 35-ton class long-reach amphibious excavator specifically engineered for deep-water dredging, wide river engineering, and large-scale wetland construction projects. Designed for demanding applications in Europe and the Middle East, this model combines extended reach capability with exceptional floating stability and heavy-duty performance.

At the foundation of the HK300SDA is a reinforced high-buoyancy pontoon undercarriage, purpose-built to support long boom and arm configurations. With pontoons measuring up to 9.6 meters in length and 1.8 meters in width, the machine maintains excellent balance and flotation even when operating at maximum reach. The low ground pressure of approximately 0.14 kg/cm² allows the excavator to work efficiently on soft mud, silt, marshland, and submerged terrain without excessive sinking or soil damage.

Power is delivered by internationally recognized diesel engines, including the Isuzu 6BG1TRP-03 and Mitsubishi 4M50 turbocharged engines, producing up to 118 kW of output. These engines are widely used across global construction markets and are valued for their durability, fuel efficiency, and ease of maintenance. This makes the HK300SDA particularly suitable for overseas projects where long-term reliability and service accessibility are critical.

The hydraulic system features a Doosan T5V112 dual variable plunger pump combined with a PARKER AV280 control valve, generating a working pressure of up to 32 MPa. This configuration ensures smooth, precise control of the long boom and arm, even during extended dredging cycles. Operators benefit from stable motion, accurate positioning, and consistent digging force when working at depths exceeding 10 meters.

With a maximum digging reach of approximately 15.5 meters and a maximum digging depth of over 10.8 meters, the HK300SDA is ideal for large river dredging, port maintenance, flood control channels, and deep wetland excavation. The standard 0.5 m³ bucket is carefully matched to the long-reach setup, providing efficient material handling while maintaining machine stability.

Mobility is handled by a four-motor travel system using DOOSAN TM40VC motors, offering improved traction and control during floating and shoreline transitions. The slew system operates at a controlled speed of 11 rpm, allowing precise alignment during dredging and loading operations. Reinforced chains and structural components further enhance durability in abrasive and submerged working conditions.

For projects involving deeper water, stronger currents, or higher stability requirements, the HK300SDA can be equipped with additional pontoons and a spud anchoring system. This optional configuration allows the excavator to maintain a fixed working position, improving safety and efficiency during long-reach operations.

From a procurement standpoint, the HK300SDA is optimized for export delivery and project-based purchasing. Standard payment terms include 30% T/T down payment and 70% before delivery, with a production lead time of approximately 45 days after deposit receipt. This makes the machine suitable for EPC contractors, rental fleets, and government-funded infrastructure projects operating under strict timelines.
