The HEKING HK300SDA is a long-reach wetland excavator developed for construction and excavation work in challenging ground and water-area conditions. With a total weight of 36,000 kg and a maximum digging reach of 15.426 m, it is configured for projects where extended working reach and amphibious mobility are important equipment requirements.
The HK300SDA combines a conventional upper excavator structure with a purpose-built amphibious pontoon undercarriage. The undercarriage uses four travel motors, strengthened track shoes and chains, and Q345B structural material. The pontoon construction uses 6 mm top and side plates and an 8 mm bottom plate.
For projects requiring additional flotation or stabilization, the machine can be supplied with optional additional pontoons and spud systems. These options should be evaluated against the actual water depth, ground conditions, working method and project requirements.
For professional buyers, the HK300SDA is positioned as a project-oriented machine for wetland construction, dredging and other operations where a standard excavator configuration may not provide the required access or working reach.
The HK300SDA uses an 8,600 mm boom and 6,260 mm arm. Its maximum digging reach is 15.426 m, while the maximum digging depth is 10.858 m. These dimensions provide an extended working envelope for excavation and dredging tasks where the work area cannot be approached directly by a conventional machine.
The specified maximum digging height is 14.101 m and maximum dumping height is 11.889 m. Actual working performance depends on the operating configuration, attachment and site conditions.
The amphibious undercarriage is the defining configuration of the HK300SDA. The machine uses four travel motors, allowing the track system to be driven through four independent travel motor positions.
The pontoons are manufactured from Q345B material. The stated hull plate thickness is 6 mm at the top, 6 mm at the sides and 8 mm at the bottom. The specification also lists a 1,936 mm ground clearance of the platform and a 1,126 mm minimum ground clearance.
The machine has a listed ground pressure of 0.14 kg/cm². This characteristic is relevant when evaluating the machine for soft-ground and wetland applications, although final suitability should be confirmed against actual soil, water and operating conditions.
The HK300SDA uses a Doosan T5V112 hydraulic pump and PARKER AV280 valve. The specification identifies the pump as a variable plunger pump with a maximum displacement of 2 × 112 cm³/r and maximum flow of 2 × 240 L/min.
The listed working pressure is 32 MPa. The machine uses a fixed-plunger slew motor and variable-plunger travel motors.
The specified engine options are Mitsubishi 4M50-TLC3J and Isuzu 6BG1TRP-03. The supplied engine specification lists inter-cooled turbo configuration, 118 kW power at 2,000 rpm, 620 N·m maximum torque at 1,500 rpm, four cylinders and 4.899 L displacement.
Buyers should confirm the final engine configuration when requesting a quotation because two engine models are listed for this product.
The HK300SDA is intended for project environments where amphibious access and extended excavation reach are required.
| Application | Typical Use |
| Wetland construction | Excavation and construction work in wetland and soft-ground areas |
| River dredging | Extended-reach excavation and dredging operations |
| Swamp and marsh projects | Excavation where low listed ground pressure and amphibious undercarriage configuration are relevant |
| Environmental engineering | Machinery support for wetland and water-area engineering projects |
| Shallow-water operations | Excavation where an amphibious machine configuration is required |
| Soft-ground projects | Work in ground conditions requiring specialized flotation and undercarriage configuration |
The product information specifically identifies wetland, water and environmental engineering as relevant areas for Hekuang's amphibious equipment. The exact operating method should be determined according to the project design and site conditions.

The HK300SDA provides a maximum digging reach of 15.426 m, with an 8,600 mm boom and 6,260 mm arm. This configuration supports excavation work where the machine needs to maintain working distance from the excavation area.
The undercarriage uses four DOOSAN TM40VC travel motors. The four-motor configuration is part of the machine's amphibious travel system and should be considered when evaluating mobility requirements for the intended site.
The pontoons use Q345B material with 6 mm top and side plates and an 8 mm bottom plate. Strengthened track shoes and chains are also specified for the undercarriage.
The HK300SDA has a specified ground pressure of 0.14 kg/cm². This makes ground-pressure evaluation an important part of assessing its suitability for soft-ground and wetland projects.
Additional pontoons and spud systems are available as optional configurations for specified deep-water applications. The final configuration should be determined according to project water depth and operating requirements.
Before ordering an HK300SDA, project buyers should confirm the actual working environment and required machine configuration.
