Hyundai compact excavators
The 9A Series models appeal to renters with ease of use, standard quick couplers and pattern-change valve.
The quick couplers enable operators to take on a variety of jobs, a key consideration for rental houses and customers who rent machines. The quick-coupler is standard on all 9A series models except the smallest unit, the R17Z-9A. Auxiliary hydraulic piping also is standard, accommodating a variety of attachments.
A standard pattern-change valve, positioned for easy access, changes joystick control from SAE to ISO pattern, depending on operator preference. This is especially useful for rental fleets, where a new operator may be in the cab every day.
Advanced hydraulic technologies
Innovative, precision hydraulic system technologies make Hyundai 9A series excavators fast, smooth and easy to control. Hyundai redesigned the hydraulic system on the three largest 9A series models to provide the operator with super-fine touch and improved controllability, which enhances operating precision. The arm flow summation system combines flow from both pumps, reducing cavitation and increasing arm speed.
The standard boom swing function enables the boom to be offset 75 degrees to the left and 50 degrees to the right for efficient work in congested areas. Other standard features include factory-installed thumb brackets and large dozer blades.
Enhanced reliability features include bushings designed for long-life lube intervals and integrated preheating systems which extend service intervals and reduce machine downtime.
The canopy-style frame ensures operator safety and complies with international standards for TOPS, ROPS and FOPS. The 9A series models feature foldable pedals for added space. The cab includes multiple storage compartments, a feature appreciated by operators.
Control devices are all located for improved operator comfort and productivity. The LCD cluster display in the three larger models monitors seven warning indicators, water temperature gauge, fuel gauge and hour meter for productive, convenient operating. The operator experience is enhanced with a fully adjustable suspension seat, wrist rests, ergonomically designed joysticks and plenty of legroom.
Hyundai’s 9A series includes six compact excavator models, including three zero-tail swing models, two compact-radius models and one model with a standard counterweight configuration.
6-ton model popular in rental market
Among the more popular compact models is the 6-ton (5800 kg) Hyundai R60CR-9A, a compact-radius model powered by a Tier 4 Final-certified Yanmar engine, with net power of 63 hp. Bucket breakout force is 8,220 ft.-lbs. and maximum dig depth is 11 feet 9 inches.
The standard auto-idle function on the R60CR-9A can reduce engine speed automatically when operators are not using the control levers, improving fuel efficiency.
Hyundai excavators are compatible with a full spectrum of third-party attachments, as well as Hyundai brand hydraulic breakers. The R60CR-9A features a tilting cabin for convenient maintenance and service
