The HEKING AUP140 Amphibious Undercarriage Pontoon is a professionally engineered floating undercarriage solution developed for 12–15 ton crawler excavators. It is designed to extend the operational capability of standard excavators into environments where conventional tracked undercarriages cannot perform reliably, such as wetlands, riverbanks, shallow water zones, soft mud, and reclaimed land.

With a pontoon length of approximately 9.2 meters, a 1.4 meter width, and a 1.8 meter height, the AUP140 provides a compact yet stable buoyancy profile. This size configuration makes it particularly suitable for projects with limited working space, including irrigation channels, drainage systems, small rivers, and environmentally sensitive areas. The narrower pontoon width allows easier transportation and access to confined job sites commonly found across Europe and the Middle East.

The structural integrity of an amphibious undercarriage pontoon is critical for long-term reliability. The AUP140 features a fully welded steel hull structure, utilizing 6 mm thick plates on the top, sides, and bottom. This uniform thickness design provides sufficient strength for medium-duty amphibious operations while maintaining a lighter overall structure compared to larger pontoon systems. The reinforced hull protects against underwater debris, sediment abrasion, and repeated loading cycles.

For propulsion and maneuverability, the AUP140 is equipped with four hydraulic travel motors. This configuration ensures smooth and controlled movement on water surfaces, marshy ground, and soft soil conditions. The four-motor layout offers a practical balance between traction, energy efficiency, and maintenance cost, making it suitable for contractors seeking reliable amphibious performance without excessive operational complexity.

As an amphibious excavator conversion undercarriage, the AUP140 allows contractors and fleet owners to transform existing excavators into amphibious machines instead of investing in entirely new equipment. The undercarriage can be adapted to most mainstream excavator brands within the 12–15 ton class, providing flexibility for mixed fleets and project-based procurement strategies.

For deeper water applications or jobs requiring precise positioning, the AUP140 can be supplied with optional additional pontoons and a spud anchoring system. The spud system allows the excavator to maintain a fixed working position during excavation or dredging, improving safety, operational accuracy, and productivity. This option is especially valuable in canal maintenance, pond cleaning, and light dredging works.

From a logistics and export perspective, the HEKING AUP140 Amphibious Undercarriage Pontoon is designed with international shipment and assembly efficiency in mind. Its modular construction supports containerized transport and on-site installation, reducing downtime and simplifying deployment for overseas projects. This makes the AUP140 a practical solution for distributors, rental companies, and infrastructure contractors serving Europe and the Middle East.
