Product Description
Engineered for demanding excavation operations, this 2014 SY215C-9 represents Sany's commitment to hydraulic excellence and robust construction. Powered by a 114kW engine operating at 2050 rpm, this 21-ton excavator delivers exceptional performance through its dual-pump hydraulic system, generating 2×210 l/min flow at 34.3 MPa main circuit pressure. The water-cooled powertrain ensures consistent operation under sustained workloads.
Technical specifications demonstrate superior capability: 138kN bucket digging force and 103kN arm digging force enable efficient material handling across diverse applications. The 0.93m³ bucket capacity (adjustable 0.8-1.2m³) combines with a 9950mm maximum digging radius and 6600mm digging depth to provide extensive working range. Operational versatility is enhanced by 70% gradeability and 5.4 km/h travel speed.
Key performance features include:
- Rated power: 114kW at 2050 rpm with water-cooling system
- Hydraulic flow: Dual 210 l/min pumps for responsive control
- Working weight: 21,800kg with 46.5 kPa ground pressure
- Maximum reach: 9950mm radius, 9570mm digging height
- Transport dimensions: 9680×2980×3440mm
