Hyundai’s 9A series of Tier 4 Final compact excavators range from 1.7 to 8.2 metric tons, and include the mini R17Z-9A, R25Z-9A, R35Z-9A, R55-9A and R60CR-9A models and the midi R80CR-9A model.

“The new Hyundai 9A series compact excavators are all about bringing big power to small spaces. Each model features an environmentally friendly engine that provides impressive performance and reduced fuel consumption,” said Corey Rogers marketing manager, Hyundai Construction Equipment Americas.

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.

The cabs deliver reduced noise and increased comfort and visibility. A tilting left-side console makes entry and exit easier. An adjustable suspension seat and plenty of space helps reduce operator stress and fatigue. The cabs 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 on the R25Z-9A and R35Z-9A models allows joystick control to be changed from SAE to ISO pattern. The LCD cluster on the 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.

Hyundai redesigned the hydraulic system on the R55-9A, R60CR-9A and R80CR-9A 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 is designed for efficiency in congested areas. The boom can be offset left or right. Zero-tail swing on the R17Z-9A, R25Z-9A and R35Z-9A allows operators to work in confined settings. The variable undercarriage on the R17Z-9A can be adjusted to between 3 feet 3 inches and 4 feet 3 inches (990 mm and 1,300 mm) wide.
