Hitachi ZX47LC-6 excavator

The upgraded Hitachi ZX470LC-6 excavator (part of the new Dash-6 lineup) is equipped with an EPA Final Tier 4 (FT4)/EU Stage IV Isuzu engine that does not require a diesel particulate filter (DPF). It employs 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.The piston design allows particulate matter to be burned in cylinder, so there’s no need for a DPF. Grouped service points make quick work of the daily routine, and operators are able to work more efficiently with 500- and 4,000-hour engine and hydraulic oil service intervals. Swing-out coolers are easy to access and clean. Easy-to-check sight gauges and fluid reservoirs, quick-change remote-mounted filters and convenient fluid-sample ports minimize periodic maintenance downtime.D-channel side frames house and protect the coolers and FT4 engine. The boom, arm and mainframe are warranted for three years or 10,000 hours. 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. The pressurized fuel system improves fuel injector operation, and the fuel recirculation system helps prevent fuel gelling in cold climates. www.HitachiConstruction.com.
