Product Description
Built for high-output excavation and grading work, this 2021 Sany SY215C delivers 21 tons of operational capability with proven Mitsubishi 4M50 power. Rated at 118 kW and 580 N·m of torque, the water-cooled engine drives consistent performance across demanding jobsites. Bucket digging force reaches 138 kN with a standard 1.1 m³ capacity, handling trenching, loading, and material placement with precision.
- Maximum digging depth: 6,600 mm for deep utility work
- Maximum reach: 10,280 mm covers wide excavation zones
- 390-liter fuel tank supports extended shifts
- 70% gradeability tackles steep terrain
- 11 rpm rotation speed enables efficient load cycles
Currently located in Changzhou, Jiangsu, this machine is inspection-ready and available for immediate deployment. Hydraulic systems, undercarriage, and cab have been maintained to operational standards. Suitable for infrastructure projects, site development, and demolition contracts requiring reliable 21-ton class performance.
