Boliden, Epiroc and ABB Achieve Milestone

Boliden, Epiroc and ABB announced they have passed a new technology milestone by successfully deploying the first fully battery-electric trolley truck system on an 800 meter long underground mine test track in Sweden, with a 13% incline.

Each partner has provided their expertise to this development process. Epiroc has added dynamic charging to its proven battery-electric Minetruck MT42 SG and battery system, and the trolley system is equipped with ABB’s DC converter, HES880 inverter and AMXE motors to enhance the power. The mine truck features a trolley pantograph connected to an overhead catenary line, a concept which is highly suitable for long haul ramps.

“Together, in close partnerships we can accelerate the transformation and reach a steep curve in mining technology innovation like we have done in Kristineberg. In a short space of time, we have implemented and delivered technology to not only reduce CO2 emissions, but substantially extend travel distance for battery-electric driven vehicles on heavy ramp haulage, reduce operating costs, and improve the health and safety of mining environments.” said Wayne Symes, President Epiroc Underground division.
