The HEKING HK300SDA Swamp Excavator is a 36-ton amphibious excavator developed for excavation and dredging work in wetlands, swamps, marshes and other soft or water-affected working environments.
The machine combines a conventional excavator upper structure with a buoyancy-oriented amphibious undercarriage. This configuration is intended for applications where ground conditions make conventional crawler excavators difficult to operate effectively.
The HK300SDA is particularly differentiated by its long-reach working configuration. It has an 8,600 mm boom and 6,260 mm arm, with a maximum digging reach of 15,426 mm. This configuration provides a long working envelope for excavation and dredging tasks where the machine needs to reach material from a relatively extended position.
For buyers, the product is positioned as a project-oriented machine rather than a standard crawler excavator. Its technical configuration should therefore be evaluated according to the actual wetland, swamp, river or dredging conditions of the project.
The HK300SDA uses an amphibious undercarriage designed around buoyancy and operation on soft or water-affected ground.
The verified undercarriage characteristics include:
Four travel motors in total
Strengthened track shoes and chains
40Cr rollers
Q345B structural material
Large-buoyancy pontoon configuration
6 mm top hull thickness
6 mm side hull thickness
8 mm bottom hull thickness
The undercarriage has a stated ground pressure of 0.14 kg/cm². For projects involving saturated soil, wetlands or marsh areas, this specification is an important consideration when assessing machine suitability for the intended working environment.
The HK300SDA is configured with an 8,600 mm boom and 6,260 mm arm.
Its stated working ranges include:
Maximum digging reach: 15,426 mm
Maximum digging reach on ground: 15,203 mm
Maximum digging depth: 10,858 mm
Maximum vertical digging depth: 10,420 mm
Maximum digging height: 14,101 mm
Maximum dumping height: 11,889 mm
These dimensions are product specifications and should be considered together with the actual excavation position, water conditions, material characteristics and project requirements.
The machine uses a Doosan T5V112 variable plunger pump configuration. The supplied specification states a maximum displacement of 2 × 112 cm³/r, maximum flow of 2 × 240 L/min, and working pressure of 32 MPa.
The travel system uses four DOOSAN TM40VC variable-plunger travel motors. The specified maximum travel speeds are 3.3 km/h in high range and 2.17 km/h in low range.
The stated gradeability is 35° (70%), while the specified tractive effort is 382.4 kN.
The HK300SDA is available with either a Mitsubishi 4M50-TLC3J or Isuzu 6BG1TRP-03 engine.
The supplied engine specification includes:
Type: Inter-cooled turbo
Power: 118 kW at 2,000 rpm
Maximum torque: 620 N·m at 1,500 rpm
Cylinders: 4
Displacement: 4.899 L
The final engine configuration should be confirmed with Hekuang when requesting a quotation.
The HK300SDA is intended for projects requiring excavation or dredging capability in soft, wet or water-affected environments.
The amphibious undercarriage is applicable to wetland and swamp construction where soft ground can present operating limitations for conventional excavators.
Typical work may include excavation, material handling and ground-related construction activities within wetland project areas.
The long-reach configuration can be used for river dredging projects where extended working reach is relevant to the excavation task.
The machine's maximum digging reach of 15.426 m provides buyers with a defined working envelope for project planning.
The low stated ground pressure and buoyancy-oriented pontoon undercarriage make the HK300SDA applicable to marsh and other soft-ground environments.
Actual suitability depends on the site's soil, water depth, access conditions and required working method.
The HK300SDA is available with optional additional pontoons and spud equipment for deep-water applications.
Because water depth and site conditions can vary substantially between projects, buyers should provide project-specific information when requesting a configuration for deeper-water operations.

The 8.6 m boom and 6.26 m arm provide a specified maximum digging reach of 15.426 m, making the HK300SDA suitable for applications where an extended excavation envelope is required.
The pontoon-based undercarriage is designed for wetland, swamp and water-affected working environments rather than standard dry-ground excavation alone.
The specified ground pressure is 0.14 kg/cm², providing a key technical parameter for buyers evaluating operation on soft terrain.
The undercarriage incorporates strengthened track shoes and chains, 40Cr rollers and Q345B structural material. Hull thickness is specified as 6 mm at the top, 6 mm at the side and 8 mm at the bottom.
Four DOOSAN TM40VC travel motors are specified for the amphibious travel system, providing the machine with its configured four-motor travel arrangement.
Additional pontoons and spud equipment are available as optional configurations for deep-water applications, allowing project requirements to be considered during equipment selection.
