Product Description
Built in 2017 at Komatsu's Changzhou facility, this PC210-8M0 hydraulic excavator delivers 103 kW of proven power through its SAA6D107E-1 turbocharged engine. Operating at 20,100–20,550 kg working weight, the machine combines a 5,700 mm boom with a 2,925 mm arm to achieve a maximum digging reach of 9,875 mm and depth of 6,620 mm. Bucket digging force reaches 149 kN, while the 0.94 m³ capacity handles substantial material volumes efficiently.
Operators benefit from enhanced stability during demanding cycles. Ground-specific pressure stays controlled at 35.7–46.5 kPa across 600 mm track plates, while the 2,200 mm track gauge provides a stable footprint on varied terrain. Hydraulic response comes from a variable piston pump delivering 439 L/min maximum flow at 37.3 MPa working pressure. Cabin positioning offers clear sightlines to the front attachment and surrounding work area, supported by a 12.4 rpm rotation speed for smooth positioning. Currently located in Dezhou, Shandong, this joint-venture manufactured unit represents reliable mid-class excavation capability for contractors requiring consistent daily performance.
