HITACHI ZX490LCH-6 CRAWLER EXCAVATOR

The Hitachi ZX490LCH-6 is a medium-to-large hydraulic excavator engineered for demanding construction and quarry applications. Powered by an Isuzu AQ-6UZ1X engine, this machine delivers 362 horsepower (270 kW) at 2,000 rpm with a maximum torque of 1,435 Nm, providing the operational muscle required for heavy-duty excavation work. Operating at approximately 108,900 pounds, the ZX490LCH-6 features multiple boom and arm configurations offering versatile reach and digging capabilities. The machine accommodates bucket sizes ranging from 1.30 to 2.50 cubic meters, with bucket forces up to 286 kN, enabling efficient material handling across diverse job sites. Ground pressure of 12.2 psi facilitates operation on sensitive terrain, while the swing mechanism operates at 9.5 rpm for smooth rotational performance. The advanced HIOS IIIB hydraulic system represents a cornerstone feature, utilizing dual pumps and precision control valves to optimize fuel efficiency and reduce operating costs. The machine achieves approximately 5% fuel savings in ECO mode and operates with a hydraulic pump flow capacity of 211.4 gallons per minute. Meeting EPA Tier 4 Final and EU Stage IV emissions standards, the ZX490LCH-6 incorporates selective catalytic reduction (SCR) technology and a diesel oxidation catalyst, eliminating the need for diesel particulate filters. The reinforced boom with thicker plates and robust undercarriage components ensure exceptional durability for large-scale projects. With an operating range from 0 to 5.5 km/h maximum travel speed and gradeability to 70%, the machine demonstrates remarkable mobility and climbing capability. The ergonomic operator cabin, compliant with ISO standards and featuring enhanced visibility, ensures operator comfort during extended work periods.
