Product Description
Built for operators who demand precision and control, the 2020 Sany SY285C-8 is a 28-ton hydraulic excavator engineered to perform in demanding construction and earthmoving environments. Powered by a 6-cylinder Isuzu water-cooled engine producing 184 kW at 2,100 RPM, this machine delivers consistent force through every cycle — with a bucket digging force of 193 kN and a 1.35 m³ backhoe bucket ready for serious production work.
From the operator's seat, the SY285C-8 offers a commanding field of view supported by a full cab height of 3,096 mm, while the machine's 11.5 RPM rotation speed and 62 kPa ground pressure contribute to stable, confident handling across varied terrain. A climbing ability of 70% (35°) and dual travel speeds of 3.5/5.5 km/h give operators full command on slope and grade.
