Product Description
Engineered for demanding excavation operations, this 12-ton hydraulic excavator delivers exceptional performance through precision-calibrated systems. At its core, the Isuzu 4JJ1-XDJAG-01-C3 engine generates 73kW at 2000rpm with 365N·m maximum torque, providing reliable power through a water-cooled configuration and 2.999L displacement. Hydraulic superiority is evident in the 90.6kN bucket digging force and 57.2kN arm digging force, enabling efficient material handling across varied applications.
- Maximum digging reach of 7735mm with 5190mm depth capability
- Operating weight: 12,450kg with 41.6kPa ground pressure for stability
- Bucket capacity range: 0.22-0.7m³ (standard 0.55m³)
- 13.06rpm rotation speed for productive cycle times
- 70% grading ability and 425mm ground clearance
- 240L fuel capacity for extended operation periods
Manufactured in China with Sany's proven engineering standards, the SY125C combines robust construction with technical refinement. The 500mm track plates and 2680mm ground contact length ensure traction on challenging terrain, while the compact 2880mm front turning radius maintains maneuverability in confined spaces. Currently located in Hunan
