Power through the tough spots

The new ZX135US-5 has the power to boost through the tough spots. It delivers all the power, smoothness, precision and ease of operation you’ve come to expect from our larger Hitachi excavators – in an easy-to-maneuver package. With a tight tail-swing radius, this excavator is perfect for working very close to obstacles. And its optional blade dramatically increases versatility – just one machine can handle your digging, backfilling and leveling needs.

Product highlights

  • Reduced fuel consumption with a cleaner, more powerful, EPA Interim Tier 4/EU Stage IIIB-compliant Isuzu engine.
  • Tight tail-swing-radius results in more productivity around obstacles or in confined spaces.
  • Easy-to-maintain engine requires no special additional fluids − just ultra-low-sulfur diesel fuel and CJ-4 engine oil.
  • Boom, arm and mainframe are so tough, they’re warranted for three years or 10,000 hours, whichever comes first.
  • Options include several arm and shoe sizes, including rubber pads.
Ergonomically Designed Cab

Comfortable cab

Despite its short stature, the ZX135US-5 provides plenty of in-cab amenities. Perched on silicone-filled mounts, the ZX Dash-5 cab isolates noise and vibration. The spacious interior provides plenty of legroom and all-day comfort. Plus, narrow front cab posts, large overhead glass and numerous mirrors − including a couple on the counterweight − provide excellent all-around visibility. A rearview camera is optional.

Fuel-efficient engine

The Isuzu engine employs a cooled exhaust gas-recirculation (EGR) platform paired with a diesel particulate filter (DPF) to meet EPA IT4/EU Stage IIIB emissions regulations. It is easy to maintain and requires no special additional fluids – just ultra-low-sulfur diesel fuel and CJ-4 engine oil.

Ergonomically Designed Cab

Improved hydraulics

When you operate the ZX135US -5, you’ll quickly notice the smooth, responsive way our excavators go about their business. Their advanced hydraulic systems are the brain behind the brawn, perfectly balancing engine performance with hydraulic flow. They combine a hydraulic-boost system with an enhanced boom recirculation function to generate more aggressive boom/arm speed, returning the arm to the dig position faster, so you can move more dirt in a day.

Ergonomically Designed Cab

Three power modes

Three work modes let you choose the digging style that best fits the job. The E (economy) mode is perfect for light-duty work, and also reduces noise levels. The P (standard) mode provides an excellent balance of power and fuel economy for most tasks. And the H/P (high-power) mode increases engine speed to boost horsepower for working through tough spots. And when the digging gets tough, just press the power-boost button on the right-hand control to muscle through.

Ergonomically Designed Cab

More durability

Exclusive boom design features three bulkheads within the boom to resist torsional stress. This results in unsurpassed durability. Booms, arms and mainframes are so tough, they’re warranted for three years or 10,000 hours, whichever comes first.

Ergonomically Designed Cab

Easy maintenance

There’s no reason servicing an excavator should be complicated. From the self-cleaning steps and convenient grab bars that provide easy engine access, to the centralized lube banks and grouped service points – the ZX135US -5 is loaded with time- and-money saving advantages.
