Product Description
Commanding a 55-ton operating class, this 2022 Sany SY550H excavator delivers precision control and robust stability for demanding earthmoving operations. Operators benefit from excellent all-around visibility within the full-height cabin, positioned 3,470mm above ground to provide clear sightlines across the 12.8-meter working envelope. The machine's 600mm-wide track plates and 2,740mm gauge distribute 51,000kg of working weight efficiently, maintaining ground pressure at just 87.1 kPa for confident performance on variable terrain.
- 300kW rated power at 1,800 rpm for consistent hydraulic response
- 3.1-3.5m³ backhoe bucket capacity suited to high-volume excavation
- 8 rpm swing speed enables smooth, controlled rotation cycles
- 70% gradeability and 560mm ground clearance for jobsite mobility
- Dual travel speeds (5.4/3.1 km/h) balance productivity and precision
- Maximum digging depth of 8,077mm reaches deep trench requirements
Built in China and currently located in Hunan, this traditional diesel-powered excavator combines proven mechanical architecture with operator-focused ergonomics for reliable daily performance.
