The HEKING AUP330 Amphibious Undercarriage Pontoon is a large-capacity floating undercarriage system developed for converting 30–33 ton crawler excavators into high-performance amphibious excavators. Built to meet the demands of heavy civil engineering and environmental projects, the AUP330 is widely suitable for contractors operating in wetlands, rivers, lakes, coastal zones, and other challenging waterlogged environments across Europe and the Middle East.

This amphibious undercarriage pontoon features an extra-long pontoon design of approximately 11.8 meters, combined with a 1.95 meter width and 2.02 meter height, providing substantial buoyancy and stability for large excavator upper structures. The increased displacement allows the excavator to operate safely while digging, lifting, and slewing in shallow or floating conditions where conventional undercarriages cannot function.

Structural durability is a critical consideration for heavy-duty amphibious equipment. The AUP330 uses a reinforced steel hull construction, with 6 mm thick plates on the top and sides and an 8 mm thick bottom plate. This configuration protects the pontoon from abrasion, impact, and long-term exposure to sediment, rocks, and corrosive water environments, making it suitable for continuous dredging and excavation operations.

To support precise movement and reliable propulsion, the AUP330 is equipped with six hydraulic travel motors. This multi-motor layout distributes driving force evenly across the undercarriage, improving traction and directional stability during water travel and transitions between land and water. The system is especially effective when operating on soft soil, marshland, or submerged terrain where control and balance are critical.

The AUP330 is designed as a conversion-focused amphibious undercarriage pontoon, allowing owners of standard large excavators to expand their operational range without investing in a complete new amphibious machine. It can be adapted to various excavator brands within the 30–33 ton class, making it a cost-effective solution for fleet upgrades, rental companies, and specialized contractors.

For projects involving deeper water or stronger currents, the AUP330 can be supplied with optional additional pontoons and a spud anchoring system. The spud system enables the excavator to maintain a fixed working position during dredging or excavation, improving operational safety and accuracy. This option is particularly valuable for river engineering, port maintenance, and large-scale wetland restoration projects.

From a procurement perspective, the HEKING AUP330 Amphibious Undercarriage Pontoon is engineered for long-term reliability, bulk purchasing, and international deployment. Its modular construction supports efficient container or break-bulk shipping, while standardized components simplify maintenance and spare parts management for overseas customers in Europe and the Middle East.
