Meet Next Generation Of Hitachi’s Wheeled Excavator Models

The next generation of Hitachi’s wheeled excavator models, the ZX190W-5 and ZX230W-5, are rolling out with a certified EPA Interim Tier 4/EU Stage IIIB Isuzu engine, power mode buttons for three work modes, automatic exhaust filter cleaning, auto shutdown, an enhanced monitor, centralized remote oil/fuel filter location and more.

Mobile and maneuverable, Hitachi’s wheeled excavators sit on a short wheelbase that makes it easy to move in tight spaces.

The ZX190W-5 (43,880 pounds) and ZX230W-5 (51,310 pounds) are powered by a 159-hp, 5.2-liter Isuzu IT4 engine that uses a rudder frame block design with dry cylinder liners. The four-ring design helps reduce oil consumption and blow-by gases into the crankcase while improving lubrication. In addition, the oil-cooled crown efficiently aids with heat dissipation.

Both machines now feature a Power Dig function, which enables the operator to give extra hydraulic pressure for eight seconds at a time. An Auto Power Lift feature engages when only the boom is raised, giving operators extra lift while craning with no need to push the button.

A new Power Mode button allows operators to easily select between three work modes. The high power (HP) mode deploys when extra horsepower is needed for rolling in the arm or booming up during excavation work. Economy mode and Power modes can be used to lower the engine RPM and burn less fuel. hitachiconstruction.com
