Hitachi Construction Machinery — Americas has upgraded two models of its utility-class excavator line to meet EPA Final Tier IV (FT4) emission standards. The two excavators — the ZX210-6 and ZX210LC-6 — are equipped with a powerful EPA FT4/EU Stage IV Isuzu engine that provides operators with integrated, effective engine technologies and does not require a diesel particulate filter.
Designed for those working in the underground, road building, energy, commercial building and pipeline industries, the ZX210-6 and ZX210LC-6 deliver higher efficiency, reliability and durability, according to the manufacturer.
“With the upgraded ZX210LC-6 and ZX210-6, operators get the quiet, powerful performance that Hitachi is known for with the added bonus of cleaner operations,” said Mark Wall, excavator product marketing manager of Hitachi Construction Machinery — Americas. “Extremely efficient combustion and an improved piston design allow the Isuzu engine to burn particulate matter in cylinder. This eliminates the need for a diesel particulate filter.”
The ZX210-6 and ZX210LC-6 are part of Hitachi’s new Dash-6 lineup, which include the ZX250LC-6, ZX300LC-6, ZX350LC-6, ZX380LC-6 and ZX470LC-6.
Efficiency
Maintenance on the FT4 excavators is minimized to help increase uptime and reduce operating costs. Upperstructure handrails provide added safety when servicing the engine compartment, and a larger hood offers better engine accessibility. A battery disconnect switch, located in the rear door behind the cab, is easily accessible and extends battery life. In addition, engine oil, fuel and hydraulic pilot oil filters are all located on the same side at ground level for easy servicing.
Reliability
The two upgraded excavators feature a new, fuel-efficient 160 hp, FT4 Isuzu engine that is simple and efficient.
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 IV/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).
Durability
D-channel side frames house and protect the highly efficient coolers and FT4 engine. Booms, arms and mainframes are so tough, they’re warranted 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.
Productivity
With heavier operating weights of 47,245 lbs. (21,430 kg) on the ZX210-6 and 48,238 lbs. (21,880 kg) on the ZX210LC-6, these excavators take productivity to a higher level. The 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. Plus, the pressurized fuel system improves fuel injector operation, and the fuel recirculation system helps prevent fuel gelling in cold climates — so you can maintain maximum productivity.
New Options
The ZX210-6 and ZX210LC-6 are offered with new options that make it even easier for Hitachi customers to get the most out of their machines.
These models can be equipped with a grade reference-ready package that features sensor mounting brackets that are welded to the boom, arm, dogbone, counterweight and main frame of the excavator at the factory.
This reduces system installation time by half by eliminating the need to grind, weld and re-paint a machine. The brackets are compatible with Topcon, Trimble or Leica grade reference systems.
Both excavators also come with an optional auxiliary function lever that provides proportional control for auxiliary hydraulic attachments to help improve productivity on the jobsite.
