2020 Hitachi ZX470-5G

Analysis of Hitachi ZX470-5G, the pinnacle of ultra-large hydraulic excavators
As the 47-ton mining king, Hitachi ZX470-5G has set a new industry benchmark in the field of ultra-large earthworks and hard rock mining. The following are its nine core advantages that crush its peers:

1. Furious power system
💥 Isuzu GH-6HK1X turbocharged engine

287kW (385 horsepower) peak power, torque reserve up to 1800N·m

Dual-stage fuel injection technology, heavy-load fuel consumption reduced by 22%

Intelligent compensation for altitude (power loss <5% at 4000 meters)

⚡ HIOS IV hydraulic system innovation

Three-pump confluence technology, bucket digging force increased to 298kN

Intelligent flow distribution, compound action speed increased by 35%

2. Mine Destroyer Structure
🛡️ Integrally forged X-type frame

Key parts use 120mm chrome-molybdenum alloy steel, fatigue life exceeds 50,000 hours

Four-planet final drive (load capacity is 40% higher than conventional design)

⚙️ Ultra-durable working device

2.4m³ rock bucket (Hardox500 material, with automatic gear grinding warning)

Hydraulic cylinder equipped with military-grade buffer system (impact load absorption rate 95%)

III. Intelligent mining system
🧠 ConSite Pro mining version

Real-time ore density analysis (accuracy ±1.5%)

Automatically match the best excavation trajectory (production capacity increased by 18%)

🖥️ 15-inch explosion-proof touch screen

Three-dimensional ore body modeling display

Support satellite positioning production statistics
