ZX135US-3

Get a load of this

This excavator 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 tight tail-swing radius, it’s perfect for working very close to obstacles.

Product highlights

• Delivers more swing torque and bucket digging force with less emissions and noise. 
• Reduced-tail-swing design allows it to rotate freely within a small radius, so it's more productive around obstacles or in confined spaces. 
• Fuel-efficient Tier-3 emission-certified Isuzu diesel engine delivers power without compromise in all conditions. 
• Tungsten-carbide thermal-coated arm surfaces, oil-impregnated bushings and welded boom bulkheads ensure it delivers unsurpassed durability and uptime. 
• Options include several arm and shoe sizes, including rubber tracks and pads. Backfill blade size varies with shoe width. 
• ZXLink™ wireless communications system.

Better performance

At the heart of the excavator are the turbocharged Isuzu engine and our own patented HIOS III hydraulic system. Gutsy, rugged and remarkably fuel efficient, the Tier-3-certified engine outperforms the competition and work very well at high altitudes without sacrificing performance. These ultrashorts can simultaneously propel, dig and rotate with little operator effort.

Improved hydraulics

When you operate the ZX135US-3, you’ll quickly notice the smooth, responsive way our excavators go about their business. Engine performance and hydraulic flow are perfectly balanced for fast, smooth, and precise operations. The result? An increase in swing torque for faster cycle times. Plus faster arm roll-in and boom-lower/arm movement. This means you get more dirt moved more quickly at every job and more profit added to your bottom line.

Fuel-efficient engine

The Exhaust Gas Recirculation (EGR) system reduces fuel consumption with an isochronous-controlled electronic governor and a common rail-type fuel-injection system. The engine also features good cold weather starting ability and can run at higher altitudes without adjustment.

Monitor system

The intuitive, multi-language LCD monitor will provide you with instant data records such as engine speed, temperature and average fuel consumption. When changing attachments, simply match the hydraulic flow to your attachment by using the monitor – no need to leave your seat. And the operator can now program auxiliary attachment flow through our new LCD monitor in the cab.

Comfortable cab

Roomy and comfortable, your operators will love the cab. A large expanse of glass on the right side, narrow front cab posts, a large overhead window and numerous mirrors provide excellent visibility. And silicone-filled cab mounts effectively isolate operators from noise and vibration.

Three power modes

The E (economy) mode is perfect for light-duty work, reducing fuel consumption from eight to twelve percent by lowering engine speed – without sacrificing productivity. It also reduces noise levels. The P (standard) mode provides an excellent balance of power and fuel economy for most tasks. It controls the engine speed from slow to fast idle in response to the position of the engine speed dial. The H/P (high-power) mode increases engine speed to boost horsepower for working through tough spots. Then, once the resistance is overcome, engine rpm automatically returns to normal.

Simplifying service

There’s no reason servicing an excavator should be complicated. The large, easy-to-open service doors feature ample access to conveniently grouped service points. Extended service intervals and remote mounted fuel filters speed periodic maintenance. And the precision-finished cylinder blocks reduce engine oil consumption by 30 to 50 percent.
