The R 9300 G8-E, the newest electric excavator in Liebherr’s portfolio, is now available for commercial deployment. It blends Liebherr’s decades of experience with electric excavators with the proven 250-metric ton (mt) platform, the R 9300 G8. The R 9300 G8-E has an 850 kW electric drivetrain that is available in 6 KV and 6.6 kV configurations.
Liebherr said the shovel offers the same level of productivity as its diesel counterpart. It has the same hydraulic power and bucket capacity at 1.8 mt/m3 as the diesel version. The R 9300 G8-E is available in both backhoe and face shovel configuration.
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.
The shovel comes equipped with Liebherr Power Efficiency – Hydraulic Control as standard, which adapts hydraulic power to suit the machine’s load profile, reducing overall load factor on the power system. Thanks to its Generation 8 electronic architecture, 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. Customers also have the option of installing Liebherr’s autonomous cable reel solution onto the excavator to assist with cable management and support machine mobility on site.
