The HEKING HK300SD is a 30 ton wetland excavator developed for excavation, dredging and construction work where conventional crawler excavators may not be suitable for the working environment. Its amphibious pontoon undercarriage configuration is intended for applications involving wetlands, rivers, soft ground and water-area projects.
With an operating weight of 30,000 kg, the HK300SD combines a 0.8 m³ standard bucket with a maximum digging reach of 10,186 mm. Its specified ground pressure is 0.14 kg/cm², while the amphibious undercarriage incorporates three chain strands per side and dedicated travel motors.
The machine is configured around a hydraulic excavator upper structure and amphibious pontoon system. The supplied configuration includes a Doosan T5V112 pump, PARKER AV280 valve, Eaton swing motor and two DOOSAN TM60VC travel motors.
For projects requiring additional water-working capability, the HK300SD can be supplied with additional pontoons and spuds as optional equipment. The suitability of these options should be confirmed against the project's actual water depth, ground conditions, excavation method and operating requirements.

The HK300SD uses an amphibious pontoon undercarriage rather than a conventional crawler undercarriage. Each pontoon is specified at 8,285 mm in length, 1,800 mm in width and 1,700 mm in height.
The configuration provides the machine with a working platform intended for wetland and water-area applications. The specified minimum ground clearance is 1,126 mm, while the ground clearance of the platform is 1,936 mm.
The machine has a track gauge of 3,950 mm and an overall width of 5,742 mm.
The hydraulic system is specified with a variable plunger pump with a maximum displacement of 2 × 112 cm³/r and a maximum flow of 2 × 240 L/min. Working pressure is specified at 32 MPa.
The swing system uses a fixed-plunger motor, while the travel system uses variable-plunger motors. The machine has two travel motors, specified as DOOSAN TM60VC units.
The specified swing speed is 11 rpm, while high/low travel speeds are 3.3 km/h and 2.17 km/h respectively.
The HK300SD is available with a Mitsubishi 4M50-TLC3J engine, with an Isuzu 6BG1TRP-03 offered as an optional engine configuration.
The listed engine specification includes 118 kW rated power at 2,000 rpm, maximum torque of 620 N·m at 1,500 rpm, four cylinders and 4.899 L displacement.
The HK300SD has a standard bucket capacity of 0.8 m³ and a maximum bucket digging force of 122.85 kN. Maximum arm digging force is specified at 97.64 kN.
Maximum digging reach is 10,186 mm, maximum digging depth is 3,201 mm, and maximum vertical digging depth is 10,163 mm.
The maximum digging height is 7,027 mm and maximum dumping height is 6,928 mm.
These figures are product specifications and should be evaluated together with the actual soil, water, attachment and project conditions before procurement.

The HK300SD is designed for applications where excavation or dredging needs to be performed in wet or soft operating environments.
The excavator can be used for river dredging projects where an amphibious configuration is required for access to water-edge, wet and soft-ground working areas. Its 0.8 m³ standard bucket and 10,186 mm maximum digging reach provide a configuration for medium-to-heavy excavation and dredging work.
The HK300SD is suitable for wetland construction projects where conventional excavation equipment may face access or ground-pressure limitations. The amphibious pontoon configuration is designed specifically for wetland and water-area operating conditions.
The machine is applicable to selected oil and gas pipeline construction work in wet or soft terrain where excavation access is an important project consideration.
The HK300SD can be applied to flood-control excavation and waterway-related construction work, subject to project-specific ground and water conditions.
The excavator is also used for coastal engineering applications requiring excavation equipment configured for wet or soft ground.
The HK300SD is intended for challenging operating environments including:
Wetlands
Swamps and marsh-type soft ground
Rivers and water-edge areas
Soft terrain
Dredging areas
Selected coastal engineering sites
Water-related construction areas
The machine should be selected according to the actual project conditions. Water depth, soil bearing conditions, excavation depth, attachment requirements, transportation arrangements and any requirements for additional pontoons or spud systems should be confirmed before ordering.
The HK300SD has a specified ground pressure of 0.14 kg/cm². This characteristic is relevant when evaluating excavation equipment for soft-ground and wetland projects where ground loading is an important consideration.
The maximum digging reach is specified at 10,186 mm, allowing the machine to reach working areas from its amphibious platform without relying solely on conventional ground access.
The 8,285 mm × 1,800 mm × 1,700 mm pontoon configuration is designed for wetland and water-area working conditions.
The standard listed engine is the Mitsubishi 4M50-TLC3J, with the Isuzu 6BG1TRP-03 available as an optional engine configuration.
The listed configuration incorporates a Doosan T5V112 pump, PARKER AV280 valve, Eaton swing motor and two DOOSAN TM60VC travel motors.
Additional pontoons and spuds are available as options for specified deep-water applications. Project conditions should be reviewed before confirming the appropriate configuration.
