Product Description
Built in 2012 at Hefei's advanced manufacturing facility, this Hitachi ZX450H hydraulic excavator delivers 45-ton performance with proven operator-centric engineering. Powered by an ISUZU AH-6WG1TQA engine producing 235 kW at 1800 rpm, this machine combines robust digging force with refined control systems designed for extended shift work.
Operators benefit from superior visibility across the 12,050 mm maximum digging radius, supported by a spacious cab positioned 3,250 mm above ground. Dual variable swashplate plunger pumps supply 2×288 l/min hydraulic flow, enabling precise movements during demanding excavation tasks. The 1.9 m³ rock bucket configuration generates 269 kN digging force, while H-type boom and reinforced arm geometry maintain stability across uneven terrain.
- Working weight: 44,100 kg with optimized 81 kPa ground pressure
- Travel speeds: 3.4/5.0 km/h with variable axial piston motors
- Maximum digging depth: 7,890 mm for foundation and trenching work
- Hydraulic system: 30.4 MPa working circuit with reliable water-cooled operation
- Current location: Zhejiang Province, ready for inspection
Comprehensive hydraulic capacity includes 650 L fuel and dual 28
