Short-tail-swing excavators continue to grow in popularity. They are very productive because they can work in more confined areas such as near buildings and obstructions than conventional excavators. They can even work within a single lane of traffic. Due to their ultra-short counterweight, the units provide less risk of damage to the working environment as well as to the machine itself. This allows the operator to concentrate more fully on his tasks, increasing productivity. And speaking of productivity, their performance is virtually identical to their larger counterparts with the Zaxis 135US-3 comparable to the Zaxis 120-3.

Enhanced Cab
The ZX135US-3 replaces the previous 135US model. Incorporating Tier-3 standards, the new 135 also comes with an enhanced operator environment. Low-effort, short-throw levers are easy to use. This fingertip control also reduces operator fatigue. The multilingual widescreen LCD color monitor provides maintenance, attachment, and operational information. An optional air-suspension heated seat is also available.

The cab is prepped for auxiliary hydraulics. Thanks to regenerative hydraulics, arm roll-in and the boom lower/arm movement are faster. Travel speed has been increased. Multifunction operations are smoother than ever, because of the HIOS III system which further enhances the precise, smooth control for which Hitachi excavators have been known.

Productivity Improvements
The new ZX135US-3 also has greater horsepower and excellent fuel economy. Some of the retained features which help reduce operating costs include WC thermal spraying (tungsten carbide) at the arm-bucket joint for greater wear resistance at its contact surface with the bucket and HN bushings.
