In June 2023, Liebherr launched its latest mining excavator – the R 9300 Generation 8 – into the global market. Following successful validation at a mine in Indonesia with customer PT Karunia Armada Indonesia (Karunia), the R 9300 has proven its ability to improve both productivity and efficiency on site. Once the machine enters serial production in 2024, it will replace the R 9250 within the 250 t class.

IM had the chance to interview Michel Runser, the Head of Product Management at Liebherr, about the new addition to its range, discussing everything from repair and maintenance improvements versus its predecessors, its productivity upside, the field validation, as well as other aspects including fuel efficiency.

Taking just fuel as an example, 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. Liebherr Power Efficiency (LPE) – a proprietary engine and hydraulics management system that helps to decrease the amount of fuel a machine consumes while maintaining optimal productivity and performance – also comes as standard in the R 9300. An electric-drive version of the R 9300 is currently under development and will be available in the near future.

It is worth remembering that the R 9300 is only the second Generation 8 excavator in Liebherr’s product range following the R 9600 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.
