The AUP220 Amphibious Pontoon is a professional-grade pontoon undercarriage engineered for 20-22 ton excavators operating in wetlands, marshes, swamps, rivers, lakes, reservoirs, and coastal environments. Designed to transform conventional excavators into highly capable amphibious machines, this floating undercarriage allows contractors to work efficiently in areas where traditional crawler excavators cannot safely operate.
Soft ground conditions often present significant challenges for construction, dredging, environmental restoration, and infrastructure maintenance projects. Conventional excavators can easily become immobilized in mud, peat, marshland, or shallow water. The AUP220 amphibious pontoon solves this problem through a specially engineered flotation system that distributes machine weight across a larger surface area, reducing ground pressure while improving stability.
With its reinforced steel pontoon structure, four-motor drive system, and optional deep-water accessories, the AUP220 delivers reliable performance in some of the most demanding working conditions found across Europe, the Middle East, Africa, and Southeast Asia.
The AUP220 pontoon undercarriage is widely used in wetland construction projects where equipment mobility is critical. The large flotation pontoons enable excavators to travel across unstable surfaces while maintaining operational efficiency.
Typical applications include:
River dredging
Canal maintenance
Lake restoration
Wetland rehabilitation
Marshland construction
Flood control projects
Coastal engineering
Shoreline protection
Environmental remediation
Pipeline installation in wetlands
Contractors benefit from improved access to difficult work areas without requiring expensive temporary access roads or support platforms.
One of the key advantages of the AUP220 Amphibious Pontoon is its superior flotation capability. The pontoon length of 9700 mm and width of 1620 mm provide excellent buoyancy while supporting excavators in the 20-22 ton class.
The pontoon design allows the machine to maintain stability when operating in soft terrain and shallow water. Operators can perform excavation, dredging, lifting, and material handling tasks with greater confidence and safety.
The wide undercarriage configuration ranging from 4545 mm to 5345 mm further improves balance during operation. This stability becomes especially important when using long-reach booms, dredging attachments, or specialized buckets in water-based projects.
Durability is a critical consideration for amphibious equipment. The AUP220 utilizes high-strength steel pontoons manufactured with reinforced hull plates to withstand harsh working conditions.
The hull structure includes:
6 mm top plate construction
6 mm side plate construction
8 mm bottom plate construction
The thicker bottom plate provides additional protection against rocks, submerged obstacles, debris, and abrasive sediment commonly encountered in dredging operations.
This robust construction helps extend service life while reducing maintenance requirements for contractors operating in demanding environments.
The AUP220 features four hydraulic travel motors that deliver powerful traction and maneuverability in challenging terrain.
The four-motor configuration offers several benefits:
Improved propulsion efficiency
Better traction in soft soil
Enhanced turning performance
Increased reliability
Balanced power distribution
This drive arrangement allows operators to navigate through swampy areas, shallow water zones, and unstable ground conditions with greater control.
For projects involving deeper water operations, the AUP220 can be equipped with optional side pontoons and a spud system.
Additional pontoons increase flotation capacity and machine stability, while the spud system helps anchor the excavator during dredging or excavation activities. This configuration is particularly valuable for:
Deep-water dredging
Reservoir maintenance
Port construction
Coastal protection works
Waterway development projects
The modular design enables contractors to select the configuration best suited to specific project requirements.
Infrastructure development, environmental restoration, and dredging projects continue to expand throughout Europe and the Middle East. The AUP220 amphibious pontoon provides contractors with a practical and cost-effective solution for accessing difficult terrain while maintaining productivity.
Whether used for wetland conservation, flood prevention, canal dredging, or shoreline reinforcement, the AUP220 pontoon undercarriage helps maximize machine utilization and reduce project downtime.
Manufactured by HEKING, a professional amphibious equipment manufacturer, the AUP220 is built to meet the demands of international customers seeking reliable, durable, and high-performance amphibious solutions.
