Product Description
Built for precision work in confined spaces, this 2012 Hitachi ZX70 excavator delivers reliable performance across digging, grading, and material handling operations. Operating at 6,510 kg working weight with a 0.3 m³ bucket capacity, this 7-ton machine combines compact dimensions with serious digging power. The ISUZU CC-4JG1 engine generates 40.5 kW at 2000 rpm, providing consistent hydraulic flow through its variable piston pump system for responsive control under load.
Equipped with a 3.72-meter boom and 1.62-meter reinforced rod, this unit reaches a maximum digging depth of 4,170 mm and extends to 6,320 mm digging radius. Bucket digging force measures 55 kN, while rod digging force delivers 38 kN for breaking through compacted material. The machine climbs 70% grades and rotates at 11.3 rpm within a tight 1,750 mm rear turning radius, making it effective for urban construction and utility work.
- Dual-speed travel: 3.4/5.0 km/h for site mobility
- Water-cooled 4-cylinder engine with 3.318L displacement
- 135L fuel capacity for extended operation
- 2,260 mm transport width fits standard trailers
- Currently located in Jiangsu Province
