The machine matches the hydraulic performance and bucket payload rating of 1.8 t/m3 provided by its diesel counterpart.
Electric Powertrain Specifications
The R 9300 G8-E is built on Liebherr's R 9300 G8 platform and relies on an 850 kW electric drivetrain engineered in accordance with IEC standards liebherr.com

Because the machine operates without an internal combustion engine, it produces zero direct exhaust emissions at the operational site and reduces vibrations transmitted to the operator cab.
Fewer mechanical components in the electric drivetrain lower routine maintenance demands and reduce site operating expenses under specific working conditions. Depending on the electrical generation source supplying the mine, the unit allows operators to lower greenhouse gas output across extraction cycles.
Hydraulic Management and Control
The excavator comes equipped with the Liebherr Power Efficiency – Hydraulic Control architecture as a standard feature, which adjusts hydraulic power delivery based on real-time load profiles to minimize drivetrain load factors liebherr.com

Integration with Liebherr’s Generation 8 electronics enables support for the company's IoMine suite. The platform interfaces with specialized excavator Assistance Systems, the Skyview vision system, the semi-autonomous Bucket Filling Assistant, and the Data View telemetry visualization tool.
