Product Description
Engineered for demanding excavation projects, this 2020 Sany SY215C combines robust hydraulics with proven powertrain technology. At its core, a Mitsubishi 4M50 engine delivers 118 kW at 2000 rpm with 580 N·m maximum torque, paired with a water-cooled 4.9L displacement system for sustained performance in extended duty cycles. Hydraulic power translates to 138 kN bucket digging force and 103 kN arm digging force, enabling efficient material handling across varied soil conditions.
This 21-ton excavator features a 1.1 m³ bucket capacity with proven backhoe configuration. Operating specifications include a maximum dig depth of 6600 mm, reach of 10,280 mm, and dump height of 6730 mm. The undercarriage utilizes 600 mm track plates across 3445 mm ground contact length, distributing 21,900 kg operating weight to just 47.4 kPa ground pressure. Dual sprockets and 8-roller configuration per side provide stability on grades up to 70%.
Currently located in Jiangsu, China, this machine represents Sany's mid-class excavator engineering with factory-standard components throughout. Fuel capacity of 390L and 239L hydraulic reservoir support full-shift operation requirements.
