Going forward, there are many synergies with using trolley lines, which offer huge benefits in terms of CO2 reduction.By going electric, the vehicles, when on-trolley, only use around 30-50 litres an hour, which equates to a reduction in diesel consumption of as much as 350 litres an hour, making operations much more CO2 efficient.
In addition, the speed of the trucks will increase resulting in a higher throughput. Operators can also start to think about parking some of their fleet, which will bring additional indirect value to overall operational improvements through better maintenance planning to improve fleet availability and fleet longevity.
ABB in partnership with a leading mining company has implemented the trolley assist systems in an open-pit copper mine. The aim is to reduce annual diesel usage by 800,000 liters and carrying 70 Mt of ore every year at the mine without using fossil fuel for four haulage trucks on a 700 meter trolley line.
The biggest challenge lies in redesigning existing diesel-powered mines to integrate new electrification systems. Asset lifecycle strategies, ownership models and duty cycles are all subject to change. A very clear technology roadmap is essential to make the transition. Read more.
