Proterra and Komatsu have announced a new collaboration to electrify next generation underground mining machines using Proterra’s battery technology.
Proterra will supply its H Series battery system technology to Komatsu for the development of battery-electric LHDs, drills and bolters for underground hard rock mining. Komatsu will develop prototype machines this year before the expected start of commercial production in 2022.
The collaboration represents Proterra’s entry into the underground mining equipment market.
