Hyundai Construction Equipment Americas recently began delivering its new 9A series of Tier 4 Final-compliant compact excavators.
The new Hyundai 9A series models R17Z-9A and R25Z-9A are powered by Kubota engines, and the R35Z-9A, R55-9A, R60CR-9A and R80CR-9A are powered by Yanmar engines. Both the Kubota and Yanmar engines provide efficient fuel combustion and reduced noise. The product line gives contractors a choice of models in each of six popular weight classes: 1.7, 2.5, 3.5, 5.5, 6.0 and 8.2 metric tons.
Comfortable, durable operating environment
The spacious, ergonomically designed cabs deliver reduced noise and increased comfort and visibility. A tilting left-side console makes it easier for the operator to enter and exit the cab, and the left and right control levers are located for convenient access. An adjustable suspension seat and plenty of space helps reduce operator stress and fatigue. The cabs on the Hyundai 9A series machines are all TOPS, ROPS and FOPS certified. Other safety features include optional boom and arm cylinder locks, and an optional overload alarm.
An optional lever pattern change valve, positioned for easy access, on the R25Z-9A and R35Z-9A models allows joystick control to be changed from SAE to ISO pattern, depending on operator preference. The advanced LCD cluster on the Hyundai R55-9A, R60CR-9A and R80CR-9A allows the operator to select other machine preferences. The same monitor also displays engine rpm, oil and water temperature and information for all onboard electronic devices. Button selections are provided for auto idle mode, max power mode and travel speed.
To achieve optimum precision on the R55-9A, R60CR-9A and R80CR-9A models, Hyundai redesigned the hydraulic system to provide the operator with super-fine touch and improved controllability. An arm flow summation system provides energy savings, reduced cavitation and increased speed.
The boom swing function on the 9A series compact excavators is designed for efficient work in congested areas. The boom can be offset left or right. Zero-tail swing on the Hyundai R17Z-9A, R25Z-9A and R35Z-9A allows operators to work near buildings, in single lanes on roadways or in other confined settings. The variable undercarriage on the R17Z-9A – which can be adjusted to between 3 ft. 3 in. and 4 ft.3 in. (990 mm and 1,300 mm) wide – allows the most compact machine in the line to work in even the tightest limited-space work environments.
