Product Description
Built for precision and all-day productivity, this 2020 Hitachi ZX210K-5A delivers 21-ton performance with operator-first engineering. Powered by a 113 kW Isuzu turbocharged engine, it combines 158 kN bucket digging force with refined hydraulic response across dual variable axial piston pumps. Operators benefit from enhanced cabin visibility, reduced vibration levels, and intuitive joystick controls that translate to confident handling on demanding jobsites.
- Operating Weight: 21,000–21,100 kg
- Engine: Isuzu 4HK1, 113 kW @ 2000 rpm, water-cooled, turbocharged
- Digging Reach: 9,920 mm max radius / 6,670 mm depth
- Bucket Capacity: 0.91–1.0 m³
- Stability: 47 kPa ground pressure, 70% gradeability
- Hydraulics: 34.3 MPa system pressure, dual variable pumps
- Fuel Capacity: 400 L
- Location: Hangzhou, Zhejiang
Wide track gauge and low center of gravity ensure stable operation on slopes and uneven terrain, while spacious cabin design minimizes operator fatigue during extended shifts.
