The HEKING HK200SD is a 20 ton swamp excavator developed for excavation and dredging work where conventional crawler excavators may face difficult ground conditions. Its amphibious configuration combines an excavator upper structure with pontoon-based undercarriage components to provide a machine configuration intended for wetland, swamp, soft-terrain and water-related operations.
For professional contractors, equipment distributors and project procurement teams, the HK200SD provides a 20 ton-class machine configuration with a maximum digging reach of 10,778 mm, maximum digging depth of 7,033 mm and a standard bucket capacity of 0.4 m³.
The machine incorporates four travel motors, strengthened track shoes and chains, and a stated ground pressure of 0.14 kg/cm². The undercarriage can be configured with a manual extendable system or a hydraulic extendable undercarriage as an optional configuration.
The HK200SD is intended for applications where machine configuration, flotation and working reach need to be considered together rather than treating the excavator as a conventional land-based machine.

The HK200SD uses pontoon-based undercarriage components with a pontoon length of 9,258 mm, width of 1,466 mm and height of 1,797 mm according to the supplied specification data.
The overall machine width is specified as 4,231 mm in the retracted configuration and 5,051 mm in the extended configuration. Track gauge is listed as 2,598 mm / 3,398 mm.
This configuration is relevant when equipment needs to operate across wet or soft ground conditions where conventional excavator configurations may not provide the required operating arrangement.
The HK200SD uses four DOOSAN TM22VC travel motors. Four travel motors are part of the supplied product configuration and are combined with strengthened track shoes and chains.
The travel system specification includes a maximum travel speed of 3 km/h in high range and 2.1 km/h in low range. The stated tractive effort is 157.5 kN.
The machine is available with a manual extendable undercarriage or a hydraulic extendable undercarriage as an optional configuration.
The supplied dimensions identify an overall width of 4,231 mm when retracted and 5,051 mm when extended. This configuration allows the buyer to consider machine width in relation to the intended operating environment and transport requirements.
The HK200SD is equipped with a Mitsubishi 4D34 engine rated at 70 kW at 2,200 rpm. The engine is specified as an inter-cooled turbo configuration with four cylinders and a displacement of 3.91 L.
The hydraulic system uses a DOOSAN T5V63 pump and PARKER AV170 valve. The specified working pressure is 30 MPa. The machine uses a DOOSAN TSM86-GSG140SP swing motor and four DOOSAN TM22VC travel motors.
The HK200SD is intended for project environments involving wetlands, swamps, soft terrain and water-related excavation or dredging work.
The machine can be considered for wetland construction projects where soft ground conditions require an amphibious excavator configuration.
Its pontoon undercarriage and specified low ground pressure are relevant characteristics for buyers evaluating equipment for wet or weak ground conditions.
Swamp and marsh environments can present ground-access challenges for conventional construction machinery. The HK200SD is configured specifically as a swamp excavator for these types of operating environments.
The 20 ton machine class provides a balance between excavator size, digging capability and amphibious undercarriage configuration for projects requiring excavation equipment in soft terrain.
The HK200SD can be used for river-related excavation and dredging applications where the project requires an amphibious excavator configuration.
Its maximum digging reach of 10,778 mm and maximum digging depth of 7,033 mm provide key reference points for contractors evaluating its working envelope against project requirements.
The supplied product information also identifies an additional pontoon and spud as optional equipment for deep-water applications.
Actual suitability depends on site conditions, water depth, required working configuration and project-specific equipment requirements. Buyers should confirm these parameters with the manufacturer before procurement.
