Hitachi upgrades quarry excavator offering
Hitachi has upgraded its quarry excavator offering
Hitachi is now offering the powerful ZX490LCH-6 excavator for the quarry machine market. This machine replaces the earlier ZX470 and comes with increased power and performance, as well as offering increased durability and reliability over the previous model.
The machine is said to be more rugged with thicker plates in the boom and a more durable undercarriage featuring stronger track links, master pins and upper roller brackets.
Meanwhile the firm’s novel HIOS IIIB technology is said to optimise working efficiency. This uses two pumps and control valves to reduce fuel consumption and cut costs. The ZX490LCH-6 can save up to 5% fuel in ECO mode, with the same productivity as the previous model. This hydraulic technology also has a positive impact on productivity, as it has more efficient swing, boom lowering, arm and bucket roll-out.
