Product Description
Engineered with precision in Shanghai, this 2016 Sany SY215C-9 delivers robust performance through advanced hydraulic architecture and proven mechanical design. Powered by a 114kW engine at 2050 rpm, the machine operates with dual main pumps supplying 2×210 l/min flow capacity, ensuring responsive control across all functions. The hydraulic system maintains optimal pressure distribution: 34.3 MPa for main and travel circuits, 25.5 MPa for rotation, and 3.9 MPa for precision control operations.
Operating at 21 tons with a 21,800 kg working weight, this excavator combines substantial digging force—138 kN bucket force and 103 kN arm force—with a versatile 0.93 m³ bucket capacity (adjustable 0.8-1.2 m³). The water-cooled system ensures thermal stability during extended operations, while the 70% (35°) climbing ability and 46.5 kPa ground pressure provide excellent mobility across varied terrain.
- Maximum digging reach: 9,950 mm with 6,600 mm depth capability
- Compact transport dimensions: 9,680×2,980×3,440 mm
- 11 rpm rotation speed for efficient cycle times
- Currently located in Maoming, Guangdong
