Product Description
Engineered with precision in Hefei, this 2011 6-ton excavator demonstrates Hitachi's commitment to hydraulic excellence and mechanical reliability. Powered by a robust ISUZU CC-4JG1 water-cooled engine delivering 40.5 kW at 2100 rpm, this compact machine combines a dual variable piston pump system with axial piston rotary motor technology for responsive control and fuel efficiency across demanding jobsites.
Hydraulic performance stands out with a 24.5 Mpa main overflow set pressure, generating exceptional digging forces of 41.4 kN (bucket) and 28.4 kN (rod). The variable swash plate plunger travel motors provide smooth operation with dual-speed capability of 2.5/4.5 km/h, while the 9.3 rpm rotation speed ensures productive cycle times.
Physical capabilities include:
- Maximum digging reach: 6,250 mm with 3,850 mm depth capacity
- 0.22 m³ backhoe bucket with 3.49 m boom and enhanced 1.6 m rod
- Compact transport dimensions: 6,060 × 2,060 × 2,470 mm
- Impressive 70% (35°) grading ability with 33 Kpa ground pressure
- 120L fuel tank and 95L hydraulic reservoir for extended operation
