Product Description
Built for demanding earthmoving operations, this 2020 Komatsu PC400-6 delivers serious digging performance with a 257 kN bucket digging force and a 1.8 m³ backhoe bucket — purpose-built for operators who need reliable output across large-scale excavation, mining support, and infrastructure projects. Powered by the proven Komatsu SA6D125E-2 engine producing 230 kW, this 40-ton machine maintains consistent hydraulic pressure at 38 MPa through a variable piston pump delivering up to 652 L/min. Available now from Zhejiang, China.
- Operator Comfort & Visibility: Spacious cab design with wide-angle sightlines for precise bucket placement and improved site awareness
- Stability & Footprint: 600 mm track plates and a low ground pressure of 0.79 kPa ensure solid footing on varied terrain
- Reach & Depth: Maximum digging radius of 11,810 mm and digging depth of 7,760 mm for versatile trench and bulk excavation work
- Controlled Travel: Three-speed travel system (5.5 / 4.5 / 3.2 km/h) for precise machine positioning on active job sites
- Transport Ready: Overall dimensions of 11,835 × 3,430 × 3,635 mm with a compact rear swing radius of 3,500 mm
