Hitachi offers its reduced-tail-swing Zaxis 135US-3 and Zaxis 220W-3 wheeled excavator, equipped with a wrist attachment. The ZX135US-3 replaces the 135US, and incorporates Tier 3 emissions standards, a larger CRES II cab with a wider seatback and more glass on the right hand side for improved visibility. Low-effort, short-throw levers offer ease of use and reduce operator fatigue. The ZX220W-3 also has a Tier 3 engine and comes with wheels instead of tracks. The pavement-friendly excavator has increased travel speed, greater acceleration performance and the oscillation angle of the axles has been widened for a smoother ride.
