Product Description
Built for precision earthwork and deep excavation, this 2011 Hitachi ZX210LC-3 delivers 21-ton performance with proven ISUZU AI-4HK1X power. Sourced from Hefei, Anhui Province, this joint-venture machine combines Japanese engineering with field-tested durability across demanding jobsites.
Engineered with a 0.91 m³ backhoe bucket and 9920 mm maximum digging radius, this crawler excavator tackles trenching, foundation work, and mass excavation with 151 kN bucket digging force. The 122 kW turbocharged engine with intercooler maintains consistent hydraulic flow through dual variable piston pumps, while the 5680 mm H-type boom and 2910 mm rod configuration reach 6670 mm digging depth for utility installation and site preparation.
Key specifications include:
- 21,200 kg operating weight with 600 mm track plates for stability on variable terrain
- Dual-speed travel system (3.5/5.5 km/h) for efficient site repositioning
- 70% gradeability and 44 kPa ground pressure minimize site disturbance
- 400 L fuel capacity and 200 L hydraulic reservoir support extended work cycles
- Water-cooled 4-cylinder engine (5.193 L displacement) proven for continuous operation
