The Type 35 amphibious excavator’s pontoon undercarriage stand out with their unique design and superior performance advantages, making them the preferred choice for numerous complex engineering projects.

1. Design Advantages

• Pontoon Structure: The Type 35 amphibious excavator’s chassis is equipped with pontoons typically made of high-strength, corrosion-resistant materials. This ensures durability in challenging aquatic and terrestrial environments while reducing weight and improving buoyancy efficiency. The streamlined design minimizes water resistance during movement, enhancing maneuverability. The number and placement of pontoon undercarriage are carefully calculated to maintain balance during operation, ensuring stability on water and reducing the risk of tipping.
• Track System: The specially designed tracks feature wear-resistant and anti-slip materials. On land, the wider track plates increase ground contact area, distributing the machine’s weight to prevent sinking in soft or muddy terrain—ideal for material handling and excavation in construction sites. In aquatic environments, the track design provides strong traction, allowing the excavator to overcome water resistance and move steadily in shallow waters.

2. Performance Advantages

• Superior Mobility: The Type 35’s pontoon design results in extremely low ground pressure—often half or less than that of traditional excavator pontoon undercarriages. This gives it exceptional maneuverability in swamps, wetlands, riverbanks, and other challenging terrains. It can transition seamlessly from land to water without additional transport equipment, significantly reducing construction time and costs while improving efficiency.
• High Stability: The optimized chassis structure and weight distribution provide excellent anti-tip capability. When working on water, adjusting pontoon buoyancy and counterweights ensures stable operation even under water currents, allowing for smooth excavation tasks.

3. Adaptability Advantages

• Land-Water Transition: Unlike traditional excavator pontoons, the Type 35 can switch effortlessly between land and water operations. On land, it performs standard tasks like digging, loading, and leveling. When entering water, it relies on its pontoons and track system to directly proceed with tasks such as river dredging and lake maintenance.
• Terrain Versatility: Beyond land and water, the Type 35 excels in various terrains, including rugged mountain paths, soft desert sands, and confined urban construction spaces. Its flexible track system and compact chassis design allow it to operate efficiently where traditional large equipment struggles.

4. Economic Advantages

• Cost-Effective Multifunctionality: single Type 35 amphibious excavator eliminates the need for separate land and water equipment, reducing procurement costs. Fewer machines also mean lower maintenance and management expenses, enhancing project profitability.
• Efficiency Shortens Project Timelines: Its superior mobility and rapid land-water transition capability allow quick access to different work zones, minimizing delays caused by terrain limitations. Faster project completion reduces labor, equipment rental, and other indirect costs, delivering significant economic benefits.

This comparison highlights why the Type 35 amphibious excavator is increasingly favored in complex engineering environments.
