Product Description
Built for precision and daily productivity, this 2021 Sany SY125C excavator delivers reliable performance across demanding jobsites. Operating at 12 tons with a robust Isuzu 4JJ1 engine producing 73kW of rated power, this machine combines proven hydraulics with operator-centered design. Bucket digging force reaches 90.6kN, while the 7735mm maximum digging radius provides extensive working range for medium-scale excavation, trenching, and material handling projects.
Operator comfort stands at the forefront with enhanced cabin visibility and ergonomic controls that reduce fatigue during extended shifts. The water-cooled engine maintains consistent performance, supported by a 240L fuel tank for prolonged operation. Ground-specific pressure of 41.6kPa ensures stability across varied terrain, while the 70% climbing ability tackles challenging gradients with confidence.
