Product Description
Built for precision work in confined spaces, this 2011 Hitachi ZX70 mini excavator delivers reliable performance across trenching, foundation prep, and utility installation projects. Operating at 7 tons with a 6,510 kg working weight, this machine combines compact dimensions with serious digging capability—4,170 mm maximum depth and 6,320 mm reach handle demanding site conditions without hesitation.
Power comes from an ISUZU CC-4JG1 water-cooled diesel engine producing 40.5 kW at 2,000 rpm, paired with variable piston hydraulics that generate 55 kN bucket digging force and 38 kN stick force. The 0.3 m³ bucket capacity moves material efficiently while the 450 mm track width and 30 kPa ground pressure protect finished surfaces and navigate soft terrain. Dual-speed travel (3.4/5.0 km/h) and 11.3 rpm swing speed maintain productivity throughout the workday.
Currently located in Jiangsu Province, this Hefei-manufactured excavator arrives ready for immediate deployment:
- 3.72 m boom and 1.62 m reinforced stick configuration
- Compact transport dimensions: 6,080 mm length × 2,260 mm width × 2,600 mm height
- 135 L fuel capacity and 60 L hydraulic tank for extended operation
- 70% gradeabili
