A new era of underground mining is underway. BEV (battery electric vehicle) propulsion on mobile fleets means less energy required for ventilation and less additional heat generated as mines go deeper. It means a working environment free from diesel fine particulate matter. And it means reduced planned maintenance requirements and total cost of ownership for high-tramming utility vehicles like the MacLean EV Series BT3 Boom Truck. MacLean connected the battery cycle to the mining cycle by engineering the integration of best-in-class electric drive components from around the world to deliver a BEV solution that is safe, proven and data-rich. Battery electric power, built for life underground.
