Hyundai has unveiled a new compact but powerful mini-excavator for use in confined spaces. The new R30Z-9AK has a zero tail-swing radius, while the boom can be offset left or right within an operating range, allowing the operator to work close to buildings on roadways and in inner-city urban areas.
Weighing 2,880kg, the vehicle has a large dozer blade to provide extra stability and versatility when in operation. Powered by a new Kubota D1305 engine, maximum power of 18.1kW at 2,350rpm supersedes that of the outgoing R27Z-9. The new power unit is a compact, multi-cylinder, liquid-cooled industrial diesel engine that meets the latest EU emission regulations and requires no additional aftertreatment systems.
The vehicle’s bushings provide lube intervals of 250 hours, while the polymer shims are wear-resistant and reduce noise. Long-life hydraulic filters (1,000 hours) and hydraulic oil (5,000 hours), along with a more efficient cooling system and integrated preheating system, mean operating costs are minimized and service intervals are extended.
In the cabin, operating pedals are positioned to provide additional floor space, while seats and wrist rests can be easily adjusted to meet the preferences of the operator. An additional storage box with key lock built-in, accessible under the seat, has been added for extra security.
A sliding fold-in front window can be opened and stored safely for better visibility and ventilation. Stronger, but slimmer low-stress, high-strength steel tubing for the cabin’s structure has also added to the operator’s enhanced visibility, as well as improving safety. The mini-excavator was unveiled last week at the SaMoTer exhibition in Verona, Italy.
