Hitachi’s newest wheeled excavator, the ZX190W-6, is rolling out with a certified Final Tier 4 Isuzu engine that does not need a diesel particulate filter (DPF) and includes multiple other upgrades. Mobile and maneuverable, Hitachi’s wheeled excavator weighs in at 45,300 lbs. and sits on a short wheelbase that makes it easy to work in tight spaces.
The Isuzu engine has an improved piston design, allowing particulate matter to burn in cylinder during combustion. This eliminates the need for regenerations or a DPF, saving service time and lowering operating costs. With the improved Final Tier 4 technology, Hitachi was also able to maintain or reduce total fluid consumption compared to Interim Tier 4 models.
The model’s HIOS IV hydraulic system contributes to fuel efficiency by delivering on-demand performance and the right amount of pump flow when metering pilot controls. Additionally, power and performance is balanced with three work modes: economy, power, and high productivity.
The pavement-friendly ZX190W-6 reaches speeds up to 21.7 mph and features a larger hood with springs, providing efficient access to the engine for service.
Maintenance is minimized with the ZX190W-6 — from at-a-glance gauges to grouped service points with easy access to the washer tank, air cleaner, DEF tank, and battery disconnect switch. Convenient upper structure handrails now come standard and provide easy engine access, and extended service intervals help maximize uptime.
