The HEKING HK200SD is a 20 ton amphibious excavator configured for excavation and material-handling work where conventional crawler excavators may not be suitable for soft, wet or water-affected ground conditions.
The machine combines an excavator upper structure with amphibious pontoons and an extendable undercarriage. This configuration provides the buoyancy and low ground pressure required for selected wetland, swamp, marsh and water-area operations while retaining the digging functions of a hydraulic excavator.
For project buyers, the HK200SD is positioned as a machine for applications such as wetland construction, swamp excavation and river dredging. Its maximum digging reach is 10,778 mm, with a maximum digging depth of 7,033 mm and maximum digging height of 11,860 mm.
The undercarriage can be configured in retracted or extended positions. The specified overall width is 4,231 mm when retracted and 5,051 mm when extended. This configuration allows the machine dimensions to be adapted to different operating conditions within the machine's specified configuration.
The HK200SD is also equipped with four travel motors and strengthened track shoes and chains. An additional pontoon and spud can be specified for deep-water applications.
The HK200SD uses pontoons as part of its amphibious undercarriage configuration. The specified pontoon length is 9,258 mm, with a pontoon width of 1,466 mm and pontoon height of 1,797 mm.
The pontoon structure is a key part of the machine's intended use in wet and soft operating environments, where flotation and ground-contact conditions are important considerations.
The machine is available with a manual extendable undercarriage or hydraulic extendable undercarriage as an option.
The specified overall width is 4,231 mm in the retracted configuration and 5,051 mm in the extended configuration. The corresponding track gauge is 2,598 mm or 3,398 mm.
The HK200SD uses four DOOSAN TM22VC travel motors. Four travel motors provide the specified travel-drive configuration for the amphibious undercarriage.
The product information specifies strengthened track shoes and chains. These components form part of the machine's amphibious travel configuration for soft and wet operating environments.
The specified ground pressure is 0.14 kg/cm². Ground pressure is an important consideration when evaluating excavators for soft terrain because the interaction between the machine and supporting ground affects operating suitability.
An additional pontoon and spud are available as options for deep-water applications. Buyers working on deeper water projects should confirm the required configuration with the supplier before placing an order.
The HK200SD combines a 20 ton excavator platform with an amphibious pontoon undercarriage and four-motor travel system.
Its Mitsubishi 4D34 engine is specified with an inter-cooled turbo configuration, 70 kW rated power at 2,200 rpm, 370 N·m maximum torque at 1,600 rpm, four cylinders and 3.91 L displacement.
The hydraulic system uses a variable plunger pump with a maximum displacement of 2 × 63 cm³/r and a specified working pressure of 30 MPa. The hydraulic configuration includes a DOOSAN T5V63 pump, PARKER AV170 valve, DOOSAN TSM86-GSG140SP swing motor and four DOOSAN TM22VC travel motors.
The machine's specified maximum digging force is 125 kN at the bucket and 51 kN at the arm. The maximum digging reach is 10,778 mm, while the maximum digging depth is 7,033 mm.
For project procurement, these figures should be evaluated together with the actual ground conditions, water depth, required working radius, attachment configuration and transportation requirements rather than considered independently.
The HK200SD's amphibious configuration consists of the excavator upper structure, pontoon undercarriage, track system and travel motors.
During operation, the hydraulic excavator performs the digging movement through the boom, arm and bucket. The amphibious undercarriage supports travel and positioning in the intended soft or wet operating environment.
The extendable undercarriage provides two specified width configurations:
Retracted overall width: 4,231 mm
Extended overall width: 5,051 mm
Retracted track gauge: 2,598 mm
Extended track gauge: 3,398 mm
This configuration should be considered when planning access, working stability, transportation and the operating footprint required by a project.
The HK200SD is intended for project environments where an excavator requires an amphibious configuration for soft or water-affected terrain.
Wetland Construction:
The machine can be considered for excavation and construction activities in wetland environments where ground conditions require an amphibious machine configuration.
Swamp and Marsh Operations:
The pontoon undercarriage and specified low ground pressure make the HK200SD applicable to selected swamp and marsh excavation work.
River Dredging:
The 10,778 mm maximum digging reach and amphibious configuration make the machine suitable for evaluating river and waterway excavation requirements.
Soft-Ground Excavation:
The machine is designed for operating conditions where conventional excavator ground pressure and access limitations require an alternative undercarriage configuration.
Deep-Water Projects:
For applications involving deeper water, an additional pontoon and spud are available as options. Project-specific water depth and configuration requirements should be confirmed before procurement.
The HK200SD should be evaluated according to the actual site conditions rather than selected solely according to nominal machine weight.
Important project conditions include:
Ground bearing conditions
Water-area operating requirements
Required digging reach
Required digging depth
Required working width
Access and transportation limitations
Required bucket capacity
Water depth for projects requiring additional pontoon and spud configuration
The specified ground pressure is 0.14 kg/cm², while the machine's overall width can be configured between 4,231 mm and 5,051 mm.
For projects involving deep water or unusual site conditions, buyers should provide project parameters so the required configuration can be confirmed before ordering.
