The ZX345USLC-6 HP is the largest of Hitachi’s reduced-tail-swing excavators. Whether it’s road building or work in congested quarters, the ZX345USLC-6 HP packs all the power you need into its reduced tail-swing design. It features a fuel-efficient EPA Final Tier 4 (FT4)/EU Stage IV Isuzu engine – no diesel particulate filter (DPF) needed. You also get Hitachi’s exclusive TRIAS II three-pump hydraulic technology for the industry’s fastest cycle times. This workhorse is equipped with a comfortable, full-size cab and a hefty undercarriage. A standard factory-installed auxiliary function lever with optional auxiliary hydraulic lines increases versatility and simplified maintenance keeps you running longer.

The ZX345USLC-6 HP comes standard equipped with five years of Hitachi’s Global e-Service, giving you 24/7 online access to machine location, health, utilization, fuel consumption, and other valuable information – so you can better understand costs and job site performance.

Product Highlights

  • Hitachi’s FT4 field-proven technology is simple and efficient, employing cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC) and selective catalytic reduction (SCR). An improved piston design allows particulate matter to be burned in cylinder, so there’s no need for a diesel particulate filter (DPF).
  • Auto-idle, which reduces engine speed when hydraulics aren’t in use, and auto-shutdown contribute to fuel efficiency.
  • 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.
  • Thick-plate single-sheet mainframe, box-section track frames and industry exclusive double-seal swing bearing deliver rock-solid durability.
  • The ZX345USLC-6 HP comes with our TRIAS II three-pump hydraulic system maximizes multifunction operation and delivers the fastest cycle times in the industry.
