Hyundai’s new HL975 wheeled loader (pictured) was launched at the recent SaMoTer exhibition in Italy. It has an operating weight of 26.5 tonnes and at its heart is the latest Stage IV Cummins QSG12 engine with a maximum gross power of 250kW at 2,100rpm (net power 247kW).
Higher efficiency air handling and advanced combustion enable the engine to return to the simplicity of a wastegate turbocharger without the need for a cooled exhaust gas recirculation.
Automatic shutdown of engine prevents unnecessary fuel consumption and emissions. All the models in the HL Series can turn off the engine when it enters into an ‘idling’ state; operators can select operating mode and idling time depending on work environments.
With a high-strength structure designed for power, durability of frames and attachments have been enhanced by 1.5 times compared with the previous generation 9-series.
The HL975 has joystick controls for boom, bucket and third hydraulic line as standard, and can also be fitted with joystick steering as an option.
At the same show, the company’s mini excavator, the R30Z-9AK made its debut. The machine’s compact design and zero tail swing radius allows the operator to work in confined areas such as close to buildings on roadways and in inner-city areas. The boom can be offset left or right within an operating range.
The R30Z-9AK is powered by a fuel-efficient, low-noise Kubota D1305 engine which is rated at 18.1kW (24.97hp) at 2,350rpm.
Efficient cooling systems and integrated preheating systems help to extend service intervals, minimise operating costs and reduce machine downtime.
