Product Description
Engineered with a Mitsubishi 4M50 four-cylinder engine delivering 118 kW at 2000 rpm and 580 N·m maximum torque, this 2017 Sany SY215C excavator demonstrates reliable power output for demanding excavation tasks. Operating at 21 tons with a working weight of 21,900 kg, this machine combines substantial bucket digging force (138 kN) and rod digging force (103 kN) to handle tough jobsite conditions across various soil types and applications.
Hydraulic performance stands out with a 1.1 m³ bucket capacity (adjustable 0.8–1.2 m³), maximum digging depth of 6,600 mm, and maximum reach extending to 10,280 mm. Water-cooled efficiency and a 390L fuel tank support extended operation cycles. The undercarriage features robust construction with 47 track plates per side, 600 mm track width, and 3,445 mm ground contact length, delivering 47.4 kPa ground pressure for stability on soft terrain.
