August 2015 | EquipmentWorld.com 22 marketplace | continued DPF-FREE MACHINE Hitachi Construction Machinery-Americas has added an upgraded excavator to its Dash-6 line by equipping the ZX470LC-6 with an EPA Tier 4 Final Isuzu engine. The ZX470LC-6 uses cooled exhaust gas recirculation, a diesel oxidation catalyst and selective gas reduction, and diesel exhaust fl uid injected into the exhaust stream converts the NOx into harmless water vapor and nitrogen gas after running through the catalyst. The excavator's improved piston design enables particulate matter to be burned in cylinder, eliminating the need for a DPF. In addition to updating the engine, the company added features including more handrails, redesigned fuel fi lter canisters and an added coolant expansion tank. When redesigning the ZX470LC-6, Hitachi says they put saving custom- ers' time and money at the forefront, so many of the improvements address effi ciency issues. The new handrails offer easy access to the engine and a battery disconnect switch, and grouped service points simplify the daily routine. Engine and hydraulic oil service intervals of 500 and 1,000 hours, easy-to-clean swing-out access coolers, easy-to-check sight gauges and fl uid reservoirs, quick-change remote-mounted fi lters and convenient fl uid sample ports minimize downtime due to maintenance. The ZX470LC-6, at 110,804 pounds, has a heavier operating weight than its predecessor, and enhanced boom recirculation that when combined with the machine's hydrau- lic boost system, generates aggressive boom and arm speed. The pressurized fuel system improves fuel injector operation and the fuel recirculation system reduces fuel gelling in cold climates. Machine durability is addressed through D-channel side frames that house and protect the coolers and engine, in addition to large idlers, rollers and strutted track links on the sealed and lubricated undercarriage. MOBILE APP BOOSTS PRODUCTIVITY John Deere has created a mobile application designed to help 1050K crawler dozer customers enhance productivity and effi ciency. The GoPush app, which is available for both iPhone and Android devices, includes daily service information, recommendations based on extreme site conditions, a maintenance checklist, machine setup and icon glossary, and serves a quick reference guide for operators.
