Summary
- Komatsu has developed an electric version of the PC8000-11 surface mining excavator, reducing emissions by 95% compared to the diesel model
- The adoption of electric vehicles in mining has been ongoing for decades due to the availability of on-site power plants in coal mines
- The biggest electric excavator in the world is the Bagger 293, weighing 14,200 tonnes and used for strip-mining operations in Germany
- Outside of mining, electric heavy goods vehicles, such as Volvo’s FH Electric truck, are becoming common on the roads, with improved battery technology enabling longer distances to be traveled
- Electric vehicles are becoming more attractive in heavy industry due to lower operating costs, reduced emissions, and simplified maintenance compared to fossil-fuel-powered alternatives

The article discusses the trend of electrification in heavy industries such as mining, transportation, and shipping. One prominent example highlighted is Komatsu’s PC8000-11 surface mining excavator, which is one of the largest mining excavators in the world. The electric version of this excavator, powered by a chunky power cable instead of diesel fuel, has been shown to significantly reduce emissions. Other massive electric vehicles, such as the Bagger 293 bucket-wheel excavator and Volvo’s FH Electric truck, further demonstrate the potential for electrification in heavy industries.
Despite the limitations of current battery technology that prevent extremely large vehicles like the PC8000-11 from running on batteries alone, there have been significant advancements in battery energy density. The Volvo FH Electric truck, for example, has seen improvements in battery power and energy density over a short period of time. The ability to add modular batteries to increase power output and the flexibility in designing electric drivetrains are some of the advantages of electric vehicles in heavy industries.
The application of electric vehicles in mining, shipping, and transportation industries offers significant environmental benefits, such as reducing carbon emissions and noise pollution. The transition to electrification in these sectors has been driven by the desire to mitigate the environmental impact of operations and reduce reliance on fossil fuels. However, challenges remain, including concerns about the safety and reliability of giant batteries in heavy-duty electric vehicles.
The article also highlights some of the largest electric vehicles currently in operation, including the Incat Hull 096 ferry in Australia and the Shen24 electric train in China. These examples demonstrate the potential for electrification in various modes of transport, with the aim of reducing environmental damage from extractive industries and transporting heavy loads more sustainably. The shift towards electric vehicles in heavy industries is seen as a positive step towards reducing carbon emissions and promoting the use of renewable energy sources.
The electrification of heavy-duty vehicles is a growing trend in industries such as mining, transportation, and shipping. Companies are increasingly exploring the use of electric vehicles to reduce emissions, improve efficiency, and lower operating costs. Despite challenges related to battery technology and safety concerns, the adoption of electric vehicles in heavy industries is seen as a necessary step towards achieving sustainable and environmentally-friendly operations. As technology continues to advance and battery energy density improves, the potential for electrification in heavy industries is expected to expand further in the coming years.
