Product Description
Built for large-scale excavation, the 2020 Sany SY485H is a 48-ton hydraulic excavator engineered around the Isuzu 6WG1X 6-cylinder water-cooled engine — 15.681L displacement, 300 kW at 1,800 rpm, and 1,950 N·m of peak torque. That powertrain drives a hydraulic system capable of 287 kN bucket digging force and 245 kN arm digging force, making it a reliable workhorse for mining, infrastructure, and heavy earthmoving operations.
Precision and reach define this machine's field performance. With a maximum digging radius of 11,860 mm, a digging depth of 7,490 mm, and a bucket capacity range of 2.2–3.1 m³, the SY485H handles high-volume material movement without compromise. A 70% grading ability and dual travel speeds of 5.4/3.1 km/h give operators confident mobility across demanding terrain.
