A new era of underground mining is underway. Battery electric 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, long lasting and data rich. Battery electric power, built for life underground.
