2012 Sany SY215C-8

Engineered for demanding excavation work, the Sany SY215C-8 pairs a Mitsubishi 6D34-TL water-cooled diesel engine producing 114 kW at 2,050 RPM with a dual-pump hydraulic system delivering 2 × 210 L/min at a main circuit pressure of 34.3 MPa. This hydraulic architecture gives the 21-ton machine a bucket digging force of 138 kN — numbers that reflect serious engineering discipline rather than marketing claims.
