River300 | 28-33 Metric Ton Amphibious Excavator
This amphibious excavator, engineered for 28-33 tonnes of excavation, excels in demanding environments. Featuring our exclusive patented technology, it minimizes downtime and enhances productivity, effectively reducing operational costs. We also provide OEM services tailored to your specific needs.
Features of 28-33 Ton Amphibious Excavtors
- Large Pontoons RC300: Engineered for exceptional flotation, the RC300 pontoons provide 28.8 tons of buoyancy, enhancing stability in aquatic environments.
- Wider Overall Structure (5000mm): The 5000mm-wide structure offers increased stability and operator safety by distributing weight more evenly, reducing tipping risks.
- Three Separate Watertight Compartments per Pontoon: Each pontoon has three watertight compartments, improving safety and preventing sinking if one is damaged.
- Triple Chain Track System: This system efficiently distributes track pressure, reducing wear and extending the undercarriage’s life, especially in tough terrains.
- RD300 Positioning Pile Installation: With a total buoyancy of 32 tons when fully equipped, this installation boosts stability and operational capability.
- High-Strength Steel Construction: Constructed from corrosion-resistant and wear-resistant high-strength steel for durability and long service life.
- Fully Automatic Hydraulic Control System: Provides precise, efficient operation from the cab, enhancing overall productivity.
- Custom 13 to 18-Meter Long Reach Boom: Extends from 13 to 18 meters, ideal for applications requiring extended reach.
