Hitachi Zaxis Dash-5 Excavators Debut

The first fruits of an exciting new crop of Hitachi orange excavators took their inaugural bow at CONEXPO-CON/AGG: the ZX290LC-5 and the ZX870LC-5. These two models represent the first two waves of Dash-5 Excavators to roll out this year. The ZX250LC-5, ZX290LC-5, and ZX350LC-5 will be the first to arrive at dealers.

The ZX470LC-5, ZX670LC-5, and ZX850LC-5 will launch later this summer. Other utility- and construction-sized models, including wheeled and ultrashorts as well as compacts, will roll out at a later date.

The ZX Dash-5 Series incorporate customer-driven features sure to provide superior durability and productivity while keeping operating costs low.

Thanks to optimized hydraulics, the excavators have improved arm digging force, bucket digging force, lift capacity, swing speed, swing torque, hydraulic flow, engine horsepower, and drawbar pull.

The roomier cab offers a better visibility.

The IT4 Isuzu cooled EGR engine platform is less complex to maintain than selective catalytic reduction systems while delivering the productivity, fuel efficiency, and reliability customers have enjoyed with Tier 3 models. A new exhaust filter consists of a diesel oxidation catalyst/diesel particulate filter. It requires no daily attention due to its 5,000 h service life.

Features that have been retained from the Dash-3 Series include the boom, arm, and track options, and the hydraulics and electrical components. The short-throw low-effort pilot controls are still a dream to operate. And operators can be assured of the same smooth operating control and responsive multitasking capabilities.
