The HEKING HK300SD amphibious excavator is a professional heavy-duty machine designed for challenging wetland, swamp, dredging, and coastal engineering environments. This 30-ton amphibious excavator combines excellent flotation performance, stable hydraulic output, and strong excavation force to meet the operational demands of contractors and engineering companies in Europe, the Middle East, Southeast Asia, and other international markets.
Built with reinforced pontoons and a reliable hydraulic system, the HK300SD provides efficient operation in soft terrain where conventional crawler excavators cannot work safely. The machine is widely used in river dredging, flood control projects, oil and gas pipeline construction, coastal engineering, marshland development, and environmental restoration operations.
Its low ground pressure design allows the machine to travel smoothly across muddy ground, wetlands, and shallow water without sinking. The amphibious pontoon structure provides excellent buoyancy and operational stability during excavation and dredging activities.
River dredging projects require reliable excavation equipment capable of maintaining stability in waterlogged terrain. The HK300SD amphibious excavator is specifically developed for dredging rivers, lakes, reservoirs, canals, and flood channels.
The machine features a reinforced amphibious pontoon undercarriage that improves flotation while supporting heavy excavation loads. With a maximum digging reach of over 10 meters, operators can efficiently remove sediment, mud, vegetation, and debris from waterways.
For wetland construction projects, the HK300SD provides safe movement across unstable soil conditions while reducing environmental impact. The low ground pressure minimizes surface damage, making it suitable for ecological restoration and protected wetland areas.
The machine is also suitable for:
Flood prevention projects
Coastal engineering construction
Pipeline installation in marshland
Water conservancy projects
Swamp excavation work
Shoreline reinforcement
Deep water dredging operations
The HK300SD amphibious excavator is equipped with the Mitsubishi 4M50-TLC3J turbocharged engine, delivering stable power output and fuel-efficient performance for long working hours.
The advanced Doosan T5V112 hydraulic pump system ensures smooth operation and fast response during excavation tasks. Combined with PARKER AV280 control valves, the hydraulic system provides precise movement control and reliable working efficiency in demanding operating environments.
The heavy-duty travel motors and fixed plunger swing motor improve mobility and rotational performance during dredging and excavation operations.
Key hydraulic and power advantages include:
Stable hydraulic pressure up to 32Mpa
Strong bucket digging force of 122.85kN
Efficient arm digging force of 97.64kN
Reliable travel performance in muddy terrain
Smooth swing operation for precise dredging work
This configuration helps contractors improve working productivity while reducing downtime and maintenance requirements.
One of the core advantages of the HK300SD is its heavy-duty amphibious pontoon system. The pontoons are engineered to provide superior buoyancy, stability, and durability during operations in shallow water and swamp environments.
The wide pontoon structure improves machine balance while reducing sinking risks in soft ground conditions. Reinforced steel construction enhances durability in abrasive dredging environments.
The machine can also be customized with:
Additional side pontoons
Spud systems for deep water
Extended undercarriage configurations
Customized dredging attachments
Long reach boom options
These optional solutions help contractors adapt the amphibious excavator for specialized engineering projects.
The HK300SD amphibious excavator is suitable for contractors, equipment distributors, and project companies across Europe and the Middle East. The machine is designed to handle harsh working environments including coastal zones, marshlands, flood-prone areas, and desert water projects.
The excavator supports large-scale infrastructure and environmental engineering applications where standard excavators cannot operate effectively.
HEKING provides professional manufacturing support, export services, and production management to meet international procurement requirements.
