2020 Sany SY485H-S

Built for high-output excavation demands, the Sany SY485H-S stands as one of China's most technically refined large-class excavators. Powered by an Isuzu 6WG1 turbocharged, intercooled diesel engine — displacing 15.681 liters across 6 cylinders — this machine delivers a rated output of 310 kW at 1,800 RPM and a peak torque of 2,050 N·m at 1,300 RPM. Water-cooling ensures sustained thermal stability under continuous heavy-cycle operation.

At 48,500 kg operating weight with a 2.6 m³ backhoe bucket, the SY485H-S generates a bucket digging force of 287 kN and rod digging force of 245 kN — figures that reflect serious structural and hydraulic engineering. Ground pressure is maintained at a controlled 80.42 kPa, protecting site integrity across varied terrain conditions.
