Liebherr has expanded its electric excavator range with the new R 9300 G8-E, a 250-t class platform that is now available for commercial deployment.
The R 9300 G8-E is based on the proven R 9300 G8, and, as such, is designed to provide the same level of productivity as its diesel counterpart.
Drawing on Liebherr’s extensive experience with electric excavators, the R 9300 G8-E offers the same hydraulic power and bucket capacity at 1.8 t/cu.m as the diesel version. It is powered by an 850 kW electric drivetrain that has been designed to IEC standards and is available in 6 kV and 6.6 kV configurations.
After successfully completing validation, the R 9300 G8-E is now commercially 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, Liebherr says. 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 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. 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 visualisation 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.
