Hyundai Construction’s line of compact radius excavators are designed for tight, confined job sites.
For projects requiring small excavators, the R27Z-9 and R35Z-9 zero tail swing models offer a tail-swing radius of 2.7 feet and 2.10 feet, respectively.
The 6,350-lb. R27Z-9 is powered by a 24.7 hp Mitsubishi S3L2 engine. The machine has a dig depth of 6.10 feet and bucket-digging force of 4,520 pound force.
The R35Z-9 zero tail swing weighs 8,050 lbs and is powered by a 27.3 hp Yanmar 3TNV88, water-cooled, four-cycle engine. The R35Z-9 has a dig depth of 7.2 feet and bucket digging force 7,050 pound force.
Rubber or steel tracks can be selected on either the R27Z-9 or R35Z-9.
In the middle of the Hyundai compact radius lineup are the 13,010 lb. R60CR-9 and the 18,410 lb. R80CR-9 compact radius models. The tail swing radius of the R60CR-9 is a tight 3.7 feet, while the R80CR-9 is just 4.2 feet. The large size and nimble maneuverability makes these models ideal for light construction, utility, demolition, landscaping, and other applications where space is limited, but power is needed.
Both models are powered by the Yanmar 4TNV98 diesel engine. This engine gives the R60CR-9 model 57 hp, and 59.6 hp for the R80CR-9. The dig depth for the R60CR-9 reaches 10.5. The R80CR-9 offers a dig depth of 12.5feet, making it perfect for small pipe installation and repair work.
The bucket-digging forces range from 9,190 pound force for the R60CR-9 to the R80CR-9’s 12,570 pound force.
Steel or rubber tracks are options on both models.
On the large end of the spectrum are the R145CR-9 and the R235CR-9 excavators. The 32,190 lb. R145CR-9 is powered by a Mitsubishi D04FD-TAA water-cooled, four-cycle diesel engine rated at 119 hp. It provides a digging force of 21,300 pound force and maximum dig depth of 16.1 feet. The tail swing radius of 4.10 feet makes the R145CR-9 a great fit for light excavating, utility, and roadwork.
The 52,470 lb. R235CR-9 is the largest of the compact radius models. Powered by aCummins QSB6.7 engine, the R235CR-9 boasts 151 hp and a bucket digging force of 3,2710 lbf.
With a maximum dig depth of 19 feet and aminimal tail swing radius of just 5.6 feet, the R235CR-9 provides contractors a solution for excavating or demolition in confirmed areas.
Dozer blades are optional on the R145-9 and R235-9 models.
Both R145CR-9 and R235CR-9 come standard with Hyundai’s 7-inch wide color LCD screen Cluster with toggle switch. The Cluster lets the operator choose their personal machine preferences and work modes, self diagnostics, maintenance checklists, and machine security. Hyundai offers a standard rear-view camera that can be viewed from the Cluster display.
In addition to the Cluster, both models come standard with Hi-mate, Hyundai's proprietary remote management system. This gives both operators and dealers vital information on the machine from any computer with internet access. Users can pinpoint machine locations using digital mapping, and they can set machine work boundaries, reducing the need for multiple service calls. Hi-mate saves time and money for the owner by promoting preventative maintenance and reducing machine downtime.
Hyundai 9-Series excavators offer bushings designed for extended lube intervals of 250 hours – and polymer shims to resist wear and reduce noise. You also get extended-life hydraulic filters (1,000 hours), long-life hydraulic oil (5,000 hours), along with more efficient cooling and pre-heating systems. These help extend service intervals to reduce operating costs and machine downtime.
Hyundai designed all compact-radius excavators with operator comfort and convenience in mind. Features and benefits like fully adjustable seats and armrests, large foot pedals, ergonomic joysticks, large-capacity air conditioners, improved ventilation, MP3 player/AM/FM radio and water- and dust-proofing seals all add to the overall comfort.
