The HEKING AUP220 Amphibious Undercarriage Pontoon is a heavy-duty floating undercarriage system specifically engineered to convert standard 20–22 ton crawler excavators into fully functional amphibious excavators. Designed to meet the operational demands of professional contractors in Europe and the Middle East, the AUP220 provides a reliable foundation for working in wetlands, rivers, lakes, marshland, and o
ther soft or submerged environments.
At the core of the AUP220 system is a high-buoyancy steel pontoon structure, developed to support excavators operating in waterlogged terrain where traditional undercarriages cannot function. Each pontoon measures approximately 9.6 meters in length, 1.8 meters in width, and 1.8 meters in height, delivering sufficient displacement to maintain stability during excavation, slewing, and travel operations.
Durability is a key design priority. The pontoon hull uses reinforced steel plate construction, with a thickness of 6 mm on the top and sides and 8 mm on the bottom, ensuring resistance to abrasion, impact, and long-term exposure to water and sediment. This robust structure allows the amphibious undercarriage pontoon to operate reliably in dredging, canal maintenance, flood control, and environmental restoration projects.
The AUP220 is equipped with a four-motor hydraulic travel system, providing balanced power distribution and improved maneuverability across floating platforms and soft ground. This configuration enhances traction and directional control, especially during transitions between land and water. The undercarriage layout also allows for smooth movement in shallow water, mudflats, and swampy areas.
Designed as a conversion-oriented solution, the HEKING AUP220 can be integrated with a wide range of excavator upper structures within the 20–22 ton class. This makes it an economical option for contractors and equipment owners looking to expand operational capability without purchasing a complete amphibious excavator. The modular pontoon design supports efficient transport and on-site assembly, reducing logistics costs for overseas projects.
For projects involving deeper water or stronger currents, the AUP220 can be equipped with additional pontoons and a spud anchoring system. The spud system allows the excavator to maintain a fixed working position, improving safety and accuracy during dredging and excavation tasks. This optional configuration is particularly valuable for river engineering, lake maintenance, and coastal wetland work.
From a procurement perspective, the HEKING AUP220 Amphibious Undercarriage Pontoon is well suited for bulk purchasing, fleet conversion programs, and long-term rental operations. Its standardized design, durable materials, and flexible compatibility make it a practical solution for infrastructure contractors, environmental engineering firms, and equipment conversion specialists serving Europe and the Middle East.
