Product Description
Built for contractors managing multiple job sites, this 2012 Kato HD820V offers proven Japanese engineering backed by Mitsubishi power. Operating at 20 tons with a 112.5 kW engine, this excavator delivers consistent performance whether you're rotating crews or covering equipment downtime. Its 9.91-meter reach and 6.7-meter dig depth handle standard excavation tasks across residential, commercial, and infrastructure projects.
- Dual-Mode Power: 150 kN bucket force in standard mode, 159 kN in extra mode for demanding materials
- Mitsubishi 4M50 Engine: 4.9L displacement with water-cooling for extended operational life
- Versatile Bucket Range: 0.45–1.1 m³ capacity adapts to varied site requirements
- Efficient Hydraulics: Dual 235 L/min pumps with variable axial piston design
- Compact Transport: 9.45m length fits standard lowboy trailers for quick mobilization
Currently located in Jiangxi, this machine integrates seamlessly into existing fleets requiring dependable backup capacity. Dual travel speeds (3.6/5.5 km/h) and 70% climbing ability ensure productivity across challenging terrain.
