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 capabilities include:
- Bucket digging force: 138 kN with 0.93 m³ capacity (0.8-1.2 m³ range)
- Maximum digging reach: 9,950 mm with 6,600 mm depth capability
- Operating weight: 21,800 kg with optimized 46.5 kPa ground pressure
- Climbing ability: 70% gradient (35° angle)
- Dual-speed travel: 5.4/3.3 km/h for operational flexibility
Currently located in Jinan, Shandong, this Shanghai-manufactured unit demonstrates the SY215C-9 series' engineering integrity. The precision hydraulic controls, reinforced undercarriage with 3,445 mm track ground contact, and 9,570 mm maximum excavation height make this machine suitable for infrastructure, mining, and heavy construction applications.
