Product Description
Engineered with precision in China's Kunshan manufacturing hub, this 2013 Sany SY215C-8 delivers 21-ton performance through proven Mitsubishi 6D34-TL power. Rated at 114 kW and 2050 rpm, the water-cooled diesel engine drives a dual-pump hydraulic system flowing 420 l/min combined capacity at 34.3 MPa main circuit pressure. Bucket digging force reaches 138 kN with 0.93 m³ capacity, while the 9885 mm maximum reach and 6630 mm digging depth handle demanding excavation profiles. Working weight of 20,900 kg distributes across 600 mm track plates for 45 kPa ground pressure, maintaining 70% gradient capability and 12.5 rpm slew speed.
