Built for operators who demand precision and control, the 2021 Sany SY125C 12-ton crawler excavator delivers dependable performance across a wide range of earthmoving applications. Powered by a water-cooled Isuzu 4JJ1 engine producing 73 kW at 2000 rpm and 365 N·m of peak torque, this machine handles demanding dig cycles with consistent hydraulic response. A bucket digging force of 90.6 kN and rod digging force of 57.2 kN give operators confident, responsive bucket control in tough ground conditions.
From the cab, visibility and ergonomics support long working shifts without fatigue. The full cabin height of 2740 mm and generous sightlines contribute to accurate placement across the SY125C's full operating envelope.
