Boliden, Epiroc and ABB deploy first battery-electric truck trolley system for underground mining

Swedish metals maker Boliden, technology company ABB and original-equipment manufacturer Epiroc have successfully deployed the first fully battery-electric truck trolley system on an 800-m-long underground mine test track in Sweden, with a 13% incline.    ABB says the achievement of the collaboration in Boliden’s Kristineberg mine, in northern Sweden, marks a critical moment for the mining industry as it continues to face rising pressures to balance increased outputs of critical minerals and metals with lower carbon emissions and energy use.
