The HEKING HK300SDA is a 36 ton amphibious excavator developed around an amphibious pontoon undercarriage and long-reach working configuration. It is intended for excavation and material-handling work where conventional excavators may face difficult access or low-bearing-capacity ground conditions.
The machine combines a hydraulic excavator upper structure with a buoyant pontoon-based undercarriage. Its long-reach configuration provides a maximum digging reach of 15,426 mm, while the published maximum digging depth is 10,858 mm. The standard bucket capacity is 0.5 m³.
For buyers evaluating equipment for wetland construction, river work, dredging or other water-area projects, the HK300SDA provides a machine configuration centered on reach, low ground pressure and amphibious mobility.
The undercarriage uses Q345B material and incorporates strengthened track shoes and chains, four travel motors and a pontoon structure. The published ground pressure is 0.14 kg/cm². An additional pontoon and spud configuration is available for deep-water applications.
The HK300SDA has a boom length of 8,600 mm and arm length of 6,260 mm. Its maximum digging reach is 15,426 mm, with a maximum digging reach on ground of 15,203 mm.
This reach configuration is relevant when excavation or dredging work requires the machine to operate from a relatively fixed position while reaching material farther from the machine platform.
The amphibious undercarriage incorporates pontoons and tracks to provide buoyancy and mobility in wetland and water-area working environments. The published pontoon dimensions are approximately 9,632 mm in length, 1,620 mm in width and 2,050 mm in height.
The machine has a minimum ground clearance of 1,126 mm and a published ground pressure of 0.14 kg/cm².
The HK300SDA uses four travel motors. The specified travel motor is DOOSAN TM40VC, with four units listed in the product configuration.
The travel system provides high/low travel speeds of 3.3 km/h and 2.17 km/h respectively.
The undercarriage uses Q345B material and includes strengthened track shoes and chains. The supplied product information also specifies 40Cr rollers.
The pontoon structure has a listed top thickness of 6 mm, side thickness of 6 mm and bottom thickness of 8 mm.
The hydraulic system is specified with a Doosan T5V112 variable plunger pump, Parker AV280 valve, Eaton 11020268501 swing motor and DOOSAN TM40VC travel motors.
The listed maximum pump displacement is 2 × 112 cm³/r, maximum flow is 2 × 240 L/min, and working pressure is 32 MPa.
The HK300SDA combines a long-reach hydraulic excavator configuration with an amphibious undercarriage. This configuration is particularly relevant when a project requires both extended working reach and operation on wet or low-bearing-capacity terrain.
The upper structure has an overall width range of 4,719 to 5,519 mm, while the pontoon width is 1,620 mm. The track gauge is 3,725 mm and the ground length is 5,300 mm.
The published maximum digging height is 14,101 mm and maximum dumping height is 11,889 mm. Maximum vertical digging depth is 10,420 mm.
The machine's hydraulic configuration includes a variable plunger pump, fixed-plunger slew motor and variable-plunger travel motors. The listed slew speed is 11 rpm.
The rated engine configuration is Mitsubishi 4M50-TLC3J or Isuzu 6BG1TRP-03, with an inter-cooled turbo type, 118 kW power at 2,000 rpm, maximum torque of 620 N·m at 1,500 rpm, four cylinders and 4.899 L displacement.
The HK300SDA is configured for work where excavation reach and amphibious access are important considerations.
Its long boom and arm provide a maximum digging reach of more than 15 meters. The published working range includes:
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
Minimum front slewing radius: 4,884 mm
The machine has a listed gradeability of 35° (70%) and tractive effort of 382.4 kN. Maximum bucket digging force is 122.85 kN, while maximum arm digging force is 97.64 kN.
These figures should be evaluated against the actual site conditions, attachment configuration and project requirements before procurement.
The HK300SDA is suited to project environments where a long-reach excavator configuration and amphibious undercarriage are relevant.
The amphibious configuration is intended for excavation work in wet and low-bearing-capacity terrain. The low published ground pressure and buoyant pontoon undercarriage are key product characteristics for this type of operating environment.
The long-reach configuration can be considered for river and waterway excavation where the required working envelope extends beyond the immediate machine position.
The 15,426 mm maximum digging reach and 10,858 mm maximum digging depth make the HK300SDA relevant to project evaluations involving extended-reach excavation or dredging work.
An additional pontoon and spud configuration is available for deep-water applications. The exact configuration should be confirmed according to project water depth, operating conditions and equipment requirements.
The amphibious undercarriage is designed around buoyancy and low ground pressure rather than a conventional crawler excavator configuration. This makes the HK300SDA applicable to project environments involving swamp, marsh and other soft-ground conditions where access is an important equipment-selection factor.
With a published maximum digging reach of 15,426 mm, the HK300SDA is configured for projects requiring an extended working envelope.
The machine has a published ground pressure of 0.14 kg/cm², supporting evaluation for wetland and soft-ground applications where ground-bearing conditions are important.
Four DOOSAN TM40VC travel motors are specified for the amphibious undercarriage, with high and low travel speeds of 3.3 km/h and 2.17 km/h.
The undercarriage uses Q345B material, strengthened track shoes and chains, and specified pontoon plate thicknesses of 6 mm at the top, 6 mm at the side and 8 mm at the bottom.
An additional pontoon and spud can be supplied as an optional configuration for deep-water applications, subject to project requirements.
The machine is specified with a Doosan T5V112 pump, Parker AV280 valve, Eaton swing motor and DOOSAN travel motors, providing buyers with a clearly defined hydraulic component configuration for technical evaluation.
