The HK300SDA amphibious excavator is a professional long reach excavator specially engineered for demanding wetland, swamp, river dredging, and coastal engineering applications. Designed with reinforced pontoons, extended boom configuration, and powerful hydraulic performance, this heavy-duty amphibious excavator delivers reliable operation in soft ground, marshes, shallow water, and deep water construction environments.
Compared with conventional crawler excavators, the HK300SDA offers significantly improved flotation and lower ground pressure, allowing operators to work efficiently in unstable terrain where ordinary excavators cannot operate safely. The amphibious undercarriage is manufactured using high-strength Q345B steel and reinforced structural components to ensure durability during continuous dredging and environmental construction projects.
Its 15.5-meter maximum digging reach makes this machine highly suitable for river maintenance, lake cleaning, canal dredging, flood control engineering, and deep water excavation operations. The long reach boom and arm configuration enables contractors to extend working distance while maintaining excellent digging stability and hydraulic efficiency.
The HK300SDA swamp excavator is equipped with a strengthened amphibious undercarriage system featuring four travel motors for enhanced traction and mobility. This configuration allows the machine to move efficiently across mud, wetlands, peat fields, marshes, and shallow water areas.
The reinforced track shoes and 40Cr track rollers improve wear resistance and extend service life under severe working conditions. Large buoyancy pontoons provide excellent flotation performance and operational balance even when working in deep mud or saturated terrain.
The hull structure adopts a heavy-duty thickness design:
Top plate thickness: 6 mm
Side plate thickness: 6 mm
Bottom plate thickness: 8 mm
This robust structure improves corrosion resistance and long-term durability for marine and coastal engineering environments.
For contractors handling deeper water projects, optional additional pontoons and spud systems are available to improve stability and operational safety.
The HK300SDA amphibious excavator is powered by a Mitsubishi 4M50-TLC3J inter-cooled turbo diesel engine delivering 118 kW at 2000 rpm. Combined with the Doosan T5V112 hydraulic pump and PARKER AV280 control valve system, the machine provides strong hydraulic response and smooth multi-function operation.
The hydraulic system is optimized for:
River dredging
Canal cleaning
Wetland excavation
Sediment removal
Environmental restoration
Coastal reinforcement projects
With a working pressure of 32 MPa and high digging force performance, the machine can efficiently handle heavy sediment, clay, mud, and compacted materials.
The fixed plunger swing motor and variable plunger travel motors provide smooth maneuverability and precise control during operation. The four-motor travel configuration further improves stability on soft terrain and enhances climbing capability.
The HK300SDA wetland excavator is widely used in international infrastructure and environmental projects across Europe, the Middle East, Southeast Asia, and Africa.
Typical applications include:
River dredging projects
Wetland restoration
Swamp excavation
Coastal engineering
Flood prevention systems
Oil and gas pipeline construction
Lake rehabilitation
Marshland construction
Reservoir maintenance
Environmental protection projects
Its long reach design allows operators to work from safer distances while reducing repositioning frequency, improving overall project efficiency and reducing fuel consumption.
For B2B buyers and project contractors, the HK300SDA provides a reliable solution for difficult terrain operations. The machine combines flotation capability, hydraulic power, long reach performance, and durable structure in one integrated system.
The amphibious excavator is manufactured under strict quality management standards and supported by professional factory production capabilities. The production cycle is typically within 45 days after receipt of the down payment.
