Hyundai Tier 4 Final Compact Excavators Now Available
Hyundai's 9A series of Tier 4 Final compact excavators, ranging from 1.7 to 8.2 metric tons, are now available in the U.S. and Canada. The line includes 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 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. There's a model in each of six weight classes: 1.7, 2.5, 3.5, 5.5, 6.0 and 8.2 metric tons.
The excavators feature ergonomically designed cabs that 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. Cabs on the Hyundai 9A series machines are all TOPS, ROPS and FOPS certified.
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 advanced LCD cluster on the Hyundai R55-9A, R60CR-9A and R80CR-9A allows the operator to select other machine preferences. The monitor also displays engine rpm, oil and water temperature and information for all onboard electronic devices.
The R55-9A, R60CR-9A and R80CR-9A models have a redesigned hydraulic system to provide the operator with improved controllability. An arm flow summation system provides energy savings, reduced cavitation and increased speed.
The boom swing function is designed for work in congested areas. The boom can be offset left or right. The R17Z-9A, R25Z-9A and R35Z-9A are zero tail swing models. The variable undercarriage on the R17Z-9A can be adjusted to between 3 ft. 3 in. and 4 ft.3 in. wide to work in limited-space work environments.
Enhanced reliability features include bushings designed for long-life lube intervals, wear-resistant and noise-reducing polymer shims, and integrated preheating systems which extend service intervals and reduce machine downtime. Serviceability enhancements include wide open engine hoods, centralized grease fittings and easy-change plastic air cleaners. The R60CR-9A and R80CR-9A models feature a tilting cabin for convenient maintenance and service.
