ZX345USLC-6
Perfectly packaged production

The ZX345USLC-6 is the largest of Hitachi’s reduced-tail-swing excavators. Whether it's road building or work in congested quarters, the ZX345USLC-6 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 our 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 comes standard equipped with five years of ZXLink™ Ultimate, giving you 24/7 online access to machine location, health, utilization, fuel consumption and other valuable information – so you can better understand costs and jobsite performance.

Features
  • An Isuzu EPA Final Tier 4 (FT4)/EU Stage IV engine delivers fuel-efficient and reliable performance.
  • The FT4 engine solution does not require a diesel particulate filter (DPF), saving service time and lowering operating costs.
  • 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.

  • The hefty undercarriage, designed for a 35-metric-ton machine, provides greater stability, increased lift capacity and a lower center of gravity.
  • With large idlers, rollers and strutted track links, the sealed and lubricated undercarriage is built for the long haul.


  • Reinforced D-channel side frames provide maximum cab and component impact protection.
  • Thick-plate single-sheet mainframe, box-section track frames and industry exclusive double-seal swing bearing deliver rock-solid durability.
  • Tungsten-carbide-coated surfaces protect the critical bucket-to-arm joint.
  • Our 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).

  • The ZX345USLC-6 comes with our TRIAS II three-pump hydraulic system maximizes multifunction operation and delivers the fastest cycle times in the industry.
  • Stay on schedule with generous swing torque, digging force and lift capacity.
  • Muscle through tough digging by pressing the power-boost button.
  • Optional auxiliary hydraulic lines and proportional reliefs allow in-monitor flow and pressure adjustments, and can help improve productivity on the jobsite.

  • Multi-language LCD monitor and rotary dial provide easy access to machine info and functions. Turn and tap to select work modes, monitor maintenance intervals, check diagnostic codes and set cab temperature.
  • Ergonomically correct short-throw pilot levers provide smooth operation, giving you full command from your fingertips. A standard auxiliary function lever with sliding switch on the right hand pilot joystick provides easy and precise control of attachments.
  • Optional cab and right-side boom lights provide extra illumination to extend your production.

  • Get unobstructed all-around visibility thanks to a wide expanse of front, side and overhead glass and mirrors, plus a standard rearview camera.
  • Operators get maximum support from a standard, air-suspension heated seat.
  • Automatic, high-velocity bi-level climate-control system with automotive-style adjustable louvers helps keep the glass clear, the cab comfortable and the operator productive.

  • Easy-to-reach dipstick and see-through coolant reservoir make daily checks and/or additions quick and easy.
  • Easy-to-navigate LCD monitor tracks various fluid levels and issues scheduled maintenance alerts and diagnostic information
  • Engine oil, fuel and hydraulic pilot oil filters are all located on the same side at ground level for easy servicing.
  • Ground-level-accessible coolers with easily removed pre-cleaner screens help prevent trash from plugging up the cores – helping maintain cool-running efficiency.
  • Auto-idle, which reduces engine speed when hydraulics aren’t in use, and auto-shutdown contribute to fuel efficiency.
  • A battery disconnect switch, located in the rear door behind the cab, is easily accessible and extends battery life.

  • The ZX345LC-6 is standard equipped with Hitachi’s ZXLink™ system, giving you the power to optimize your operation and maximize your profits. With the support of your dealer, you can use your data to reduce idling time as well as maximize productivity and uptime. Without ever leaving your seat, you’ll have access to fleet location, functions, hours, fuel consumption, alerts and other essential machine data. You can also view location and alert information in the field from your iOS or Android devices.
