Hitachi ZX300LC-6 excavator features more horsepower, and increased swing torque and lift capacity
Hitachi Construction Machinery– Americas has revealed the newest addition to its construction-class excavator lineup – the ZX300LC-6 with Tier 4 Final, Isuzu engine technology.
“At Hitachi, we don’t get sidetracked building every type of construction equipment. Instead, we leverage our expertise and legacy of meeting demanding mining applications to build excavators that are highly efficient, reliable and durable,” said Mark Wall, product marketing manager at Hitachi Construction Machinery – Americas.
“The new ZX300LC-6 is no exception. The machine combines power and finesse for maximum productivity on any job from site development, road building and more.”
The ZX300LC-6 is part of Hitachi’s new Dash-6 lineup which also includes the ZX250LC-6, ZX350LC-6 and ZX- 380LC-6.
Grouped service points make quick work of the daily routine and operators are able to work more efficiently with 500- and 5,000-hour engine and hydraulic oil service intervals. Easy-tocheck sight gauges and fluid reservoirs, quick-change remote-mounted filters and convenient fluid-sample ports minimize periodic maintenance downtime. Plus, whatever your grade system, Topcon, Trimble or Leica, Hitachi now offers a grade reference ready package that reduces installation time by half.
Hitachi’s field-proven technology for the ZX300LC-6 is simple and efficient, employing 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 vapour and nitrogen gas. The EGR is specifically tuned to further reduce NOx (compared to EPA Tier 4 Interim 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).
D-channel side frames house and protect the highly efficient coolers and FT4 engine. The boom, arm and mainframe are so tough that they’re under warranty for three years or 10,000 hours, whichever comes first. With large idlers, rollers and strutted track links, the sealed and lubricated undercarriage is built for the long haul.
A 7.8-litre Isuzu engine provides a 32 percent increase in engine horsepower (compared to the ZX290LC-5). In addition, the ZX300LC-6’s larger, more durable hydraulic pumps deliver greater lift capacity and increased swing torque to maximize productivity.
The larger pumps, a heavier operating weight of 64,375 pounds, and a redesigned boom and arm allow operators to use a larger bucket. The machine’s hydraulic boost system and enhanced boom recirculation generate aggressive boom and arm speed, returning the arm to dig faster, so you can move more dirt in a day.
Silicone-filled cab mounts isolate the operator from noise and vibration, and a refined LCD monitor makes it simple to tap into a wealth of performance information and functions, including programmable attachment modes.
Operators will also appreciate the wide entryway, fully adjustable high-back sculpted seat, ample storage and generous legroom. In addition, the machine features unobstructed all-around visibility thanks to a new hood design paired with a wide expanse of front, side and overhead glass and mirrors. For even more comfort, an optional air-suspension heated seat is available.
