Hyundai introduces short radius excavators
Hyundai Construction is launching a line of compact radius excavators. These advanced machines are perfect for tight and restricted job sites. On the large end of the spectrum are the R27Z-9 and R35Z-9 zero tail swing models which offer a tail-swing radius of 775 mm and 870 mm respectively. The 2,880 Kg R27Z-9 is powered by a 18.4 kW Mitsubishi S3L2 engine. The machine has a dig depth of 2,085 mm and bucket-digging force of 20.1 kN.
The R35Z-9 zero tail swing weighs 3,650 kg and is powered by a 20.4kW Yanmar 3TNV88, water-cooled, four-cycle engine. The R35Z-9 has a dig depth of 2,190 mm and bucket digging force 31.4 kN.
In the middle of the Hyundai compact radius lineup is the 5,900 kg R60CR-9 and the 8,350 kg R80CR-9 compact radius models. The tail swing radius of the R60CR-9 is a tight 1,080 mm, while the R80CR-9 is just 1,280 mm. The large size and nimble manoeuvrability 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 fuel-efficient Yanmar 4TNV98 diesel engine. This engine gives the R60CR-9 model 42.5 kW, and 44.4 kW for the R80CR-9. The dig depth for the R60CR-9 reaches 3,160 mm. The R80CR-9 offers a dig depth of 3,780 mm, making it perfect for small pipe installation and repair work. The bucket-digging forces range from 40.9 kN for the R60CR-9, to the R80CR-9's 55.9 kN. Steel or rubber tracks are an option for both.
