Liebherr Mining’s latest addition to its excavator portfolio – the R 9300 Generation 8 (G8) – is now available in Canada. The R 9300 is the second G8 excavator in Liebherr’s product range and as such comes with the latest Liebherr Mining technology as standard. This technology provides the machine with improved onsite performance as well as compatibility with Liebherr’s assistance systems and future product enhancements such as automation, zero emission technologies, and digital services.
The first R 9300 to reach Australia is now in service at the Karlawinda gold project. MACA – global contractor that works in the mining, construction, and process engineering sectors – welcomed the machine into its fleet of Liebherr excavators.
The R 9300 was chosen not only for its capacity to assist in meeting the production targets of its client, but also for the excavator’s fuel efficiency, its state-of-the-art technology, and its operational effectiveness.
The design of the R 9300 was validated with a mine contractor beginning in September 2022. The machine averaged 486 operational hours per month and 94% availability. A second validation conducted in March 2023 achieved a 26-second average cycle time. The R 9300 also attained a fuel efficiency ratio of 9.22 bcm per litre of fuel burned. When considered alongside the productivity of the machine, this establishes the next-level efficiency of the R 9300, according to Liebherr.
As a result of Liebherr Mining’s commitment to reducing emissions, the R 9300 has been designed to lower fuel consumption, and therefore decrease the amount of greenhouse gases emitted by the machine. The R 9300’s engine is available in FCO and US EPA Tier 4/EU Stage V compliant versions (with SCR after-treatment technology) to adhere to strict international emissions standards.
An electric-drive version of the R 9300 is currently under development and will be available in the near future.
To increase productivity and efficiency, a range of design improvements have been implemented in the R 9300. It has an updated attachment design that is lighter and stronger than that of the R 9250. The new attachment comes with high-performance components such as a new stick and boom design and aluminum covers all installed as standard. This lean design has enabled an increase in bucket size in both the backhoe and face shovel configurations.
The R 9300 has also been designed for simplified maintenance and a longer service life. The lifespan of the R 9300 has been increased by 33% above the R 9250 to 60,000 hours from 45,000 hours.
Further improvements can be found in the cab design of the R 9300. The new cab includes enhanced cabin ergonomics, larger touch screens, a new control panel design, and optimized visibility to help promote operator wellbeing while increasing safety.
