Product Description
Engineered with a robust 118kW power plant delivering peak torque at 2000 rpm, this 2021 Sany SY205C combines hydraulic precision with field-proven durability. Operating at 21,500 kg working weight, the excavator generates 138 kN bucket digging force and 109 kN arm digging force—critical metrics for demanding excavation work across mining, demolition, and infrastructure projects.
Built on Sany's advanced SY-C platform, this 20-ton machine features optimized hydraulic flow management that maximizes productivity while minimizing fuel consumption. The excavator's 0.9-1.1 m³ bucket capacity handles material efficiently, supported by a 10,280 mm maximum digging radius and 6,600 mm depth capability. With 70% grading ability and 440 mm ground clearance, the unit maintains stability on challenging terrain.
