Frequently Asked Questions
Everything you need to know about the Hitachi ZX350LC-6 Excavator
The Hitachi ZX350LC-6 excavator price in India typically ranges between ₹1.2 – 1.5 crores (ex-showroom). Prices vary by dealer, regional market, optional attachments, and configuration. Contact your local Hitachi dealer for the most current pricing.
The Hitachi ZX350LC-6 has an operating weight of 36,300 kg (80,028 lb) with 800 mm triple grouser shoes. Ground pressure is 51 kPa (7.4 psi). The configuration includes a 1.4 m³ bucket, 7,600 kg counterweight and a 75 kg operator.
The ZX350LC-6 is powered by the Isuzu 6HK1 — a 6-cylinder, 4-cycle, water-cooled, common-rail direct injection engine with Variable Geometry Turbo (VGT) and intercooling. Net power is 271 HP (202 kW) @ 1,900 RPM, with a displacement of 7.79 L and maximum torque of 1,080 N-m @ 1,500 RPM. Emission compliance: EPA Final Tier 4 / EU Stage IV via DOC + SCR aftertreatment.
With the 4,000 mm arm and 6,400 mm boom, the ZX350LC-6 achieves a maximum digging depth of 8,180 mm (26' 10"), maximum ground-level reach of 11,670 mm (38' 3"), and maximum cutting height of 10,750 mm (35' 3").
TRIAS II is Hitachi's three-pump hydraulic architecture that dedicates separate oil circuits to the boom, arm and bucket, ensuring responsive, independent control of each attachment. Three solenoid valves provide fine and sensitive front attachment control. The system also includes an arm recirculation cancel system (for faster arm roll-in), boom recirculating system (to redirect pressurised oil from boom lowering into the arm circuit) and a boost system during arm roll-in and boom raise operations. Working modes — ECO, Power (PWR) and High Power (HP) — optimise fuel consumption or output as needed.
The Hitachi ZX350LC-6 comes with a standard factory warranty of 4 years / 4,000 hours (whichever comes first). The machine also includes Global e-Service remote monitoring and ConSite OIL oil condition sensors as standard, enabling proactive maintenance to maximise uptime over the warranty period and beyond.
