Hitachi has upgraded three models of its utility-class excavator line to meet EPA Final Tier 4 (FT4)/EU Stage IV emission standards. The three excavators – the ZX130-6, ZX160LC-6 and ZX180LC-6 – are equipped with an EPA FT4/EU Stage IV Isuzu engine complete with integrated, effective engine technologies and do not require a diesel particulate filter.  The ZX130-6, ZX160LC-6 and ZX180LC-6 have a HIOS III hydraulic system, which balances engine performance with hydraulic flow. The hydraulic boost system and enhanced boom re-circulation generate aggressive boom and arm speed – returning the arm to dig faster, so operators can move more dirt in a day. High Productivity (H/P) delivers more power and faster hydraulic response. Power (PWR) delivers a balance of power and speed, plus fuel economy for normal operation. Economy (ECO) maximizes fuel efficiency while delivering an enhanced level of productivity. Additionally, auto-idle and auto-shutdown features contribute to fuel efficiency, and an easily accessible battery disconnect switch extends battery life. The Isuzu engines employ cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC) and selective catalytic reduction (SCR). Diesel exhaust fluid (DEF) is injected into the exhaust stream of the engine, runs through a catalyst, and turns the NOx in the exhaust into harmless water vapor and nitrogen gas. The EGR is specifically tuned to further reduce NOx (compared to EPA Interim Tier 4 [IT4]/EU Stage IIIB engines) to meet new emission standards with minimal use of DEF. Additionally, an improved piston design allows particulate matter to be burned in cylinder, so there’s no need for a diesel particulate filter (DPF). All three upgraded excavators feature unobstructed all-around visibility with a new hood design paired with a wide expanse of front, side and overhead glass and mirrors, plus a standard rearview camera. Operators get maximum support from a sculpted mechanical suspension high-back seat. And an automatic, high-velocity bi-level climate-control system with automotive-style adjustable louvers helps keep the glass clear, the cab comfortable and the operator productive. D-channel side frames house and protect the coolers and FT4 engine. Booms, arms and mainframes are warranted for three years or 10,000 hours. The excavators feature grouped service points, at-a-glance gauges and convenient upper-structure handrails that provide easy engine access. Extended service intervals help maximize uptime and scheduled maintenance is easy to track using Hitachi’s ZXLink™ system. ZXLink gives owners access to data to reduce idling time as well as maximize productivity and uptime. They have access to fleet location, functions, hours, fuel consumption, alerts and other essential machine data. You can also view location and alert information in the field from iOS or Android devices. The ZX130-6, ZX160LC-6 and ZX180LC-6 come with an optional auxiliary function lever that provides proportional control for auxiliary hydraulic attachments to help improve productivity on the jobsite. www.HitachiConstruction.com.
