Product Description
Engineered for precision and durability, this 2020 Komatsu PC70-8 mini excavator delivers proven hydraulic performance in a compact 6,500 kg working weight package. Powered by the Komatsu SAA4D95LE-5 four-cylinder, water-cooled, turbocharged and post-cooled engine producing 48.5 kW at 1,950 RPM, the PC70-8 maintains consistent output across demanding job site conditions. A variable piston main pump delivers a maximum flow of 172 L/min, with working and traveling hydraulic circuits rated at 24.5 MPa — parameters that translate directly to responsive, controllable digging force.
- Bucket Digging Force: 54.8 kN | Rod Digging Force: 38.2 kN
- Maximum Digging Depth: 4,100 mm | Maximum Digging Radius: 6,360 mm
- Bucket Capacity: 0.32–0.39 m³ with 450 mm track plates for stable ground contact
- Ground Pressure: 30.2 kPa — suitable for soft and semi-confined terrain
- Travel Speed: 4.5 / 2.8 km/h | Maximum Tractive Force: 56.4 kN
- Fuel Tank: 130 L | Hydraulic Tank: 95 L for extended operational cycles
- Location: Hunan, China — available for international export inspection
Built under joint-venture manufacturing standards in Jining, Shandong Province, the PC70-8 series reflects Komatsu's commitment to engineering integrity in the 7-ton class. Compact dimensions — 6,080 mm transport length, 1,750 mm rear swing radius — make this unit well-suited for urban construction, utility work, and confined excavation sites where larger machines cannot operate efficiently.
