Liebherr has introduced the R 9300, a cutting-edge 250-tonne mining excavator.
The new generation R 9300 is now available for purchase following its successful validation at a mine in Indonesia, where it proved both its productivity and efficiency. This new machine was first presented to an international audience at the 2022 Bauma exhibition in Munich. It will take over from the R 9250 in the 250-tonne class when it enters serial production in 2024.
Field tested
As part of the validation phase for the R 9300, Liebherr Mining partnered with its customer PT Karunia Armada Indonesia to establish the capabilities of the excavator on site.
Since the trial began, the R 9300 has averaged 486 operational hours per month and 94 per cent availability, surpassing Karunia’s KPIs for the machine. These results highlight the true potential of the excavator for improving onsite productivity.
Efficient
R 9300 has been designed to lower fuel consumption, which decreases greenhouse gas emissions.
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 – comes as standard in the R 9300. With this system, the R 9300 reduces fuel consumption by 15 per cent when compared to its predecessor, the R 9250. Further, this decrease in fuel consumption contributes to a 25 per cent increase of fuel efficiency for the R 9300 compared to Liebherr’s previous 250-tonne excavator.
An electric-drive version of the R 9300 is currently under development and will be available in the near future.
Latest design
The R 9300 has an updated attachment design that is lighter and stronger than the R 9250, enabling 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. This excavator shares parts commonality with Liebherr’s current excavators to help minimise maintenance costs and streamline onsite inventory. The lifespan of the R 9300 has been increased by 33% above the R 9250 from 45,000 to 60,000 hours.
