Liebherr delivers electric excavation power to mines with all-new 250-tonne R 9300 model
Adapt hydraulic power to suit the machine’s load profile with standard Hydraulic Control and reduce overall engine load factor
The R 9300 G8-E is the newest electric excavator in Liebherr's portfolio. It blends Liebherr's electric drivetrain with the 250-tonne platform — the R 9300 G8 — and provides the same level of productivity as its diesel counterpart.
The R 9300 G8-E offers the same hydraulic power and bucket capacity at 1.8 t/m3 as the diesel version. Its 850 kW electric drivetrain is designed to IEC standards and is available in 6 kV and 6.6 kV configurations. After completing validation, the R 9300 G8-E is now commercially available in both backhoe and face shovel configurations.
The benefits of adding an electric excavator to a mining fleet
The R 9300 G8-E's electric drivetrain produces no direct exhaust emissions at the point of use and, depending on the mine's electricity source, can reduce operational greenhouse gas emissions.
With fewer drivetrain components than an internal combustion engine, the electric configuration can also reduce maintenance requirements and associated operating costs in certain applications and site conditions. Compared with its diesel counterpart, the electric drivetrain reduces vibration exposure in the cab, further enhancing operator comfort.
Additional features and capabilities
The R 9300 G8-E comes with Liebherr Power Efficiency - Hydraulic Control as standard, which adapts hydraulic power to suit the machine's load profile, reducing overall engine load factor.
The R 9300 G8-E is compatible with a range of Liebherr's IoMine technology products, including its range of excavator Assistance Systems, the semi-autonomous Bucket Filling Assistant, the Skyview vision system, as well as the data visualization tool, Data View.
Liebherr's autonomous cable reel solution can be added to assist with cable management and support machine mobility on site.
