Komatsu mining truck operates autonomously while using trolley assist
The seamless transfer of power between the electric-drive autonomous truck and the trolley system is an industry-first achievement
Building on its history of advancements in autonomous mining, Komatsu has completed a new milestone of autonomously operating a power-agnostic electric drive truck while connected to a dynamic trolley line.
Features on Komatsu's trolley assist system
Komatsu's trolley assist system is a solution designed to help operations reduce carbon emissions, extend engine life, and support the journey toward a zero-emissions future. By connecting haul trucks to an overhead power line during uphill travel, the system delivers electric power where it's needed most, improving energy efficiency and enabling trucks to travel on grade faster when compared to standard diesel models. Integrating this with Komatsu's FrontRunner Autonomous Haulage System introduces new capabilities in mining automation, enabling further fuel savings and productivity gains.
This achievement marks the first time that Komatsu has transferred power to a moving, autonomously operated haul truck via a trolley system. The accomplishment represents a critical step in Komatsu's commitment to helping mining operations reduce emissions and enhance productivity through advanced electrification and autonomous solutions.
"This milestone demonstrates the strength of our commitment to improving our integrated technology strategy, combining autonomous haulage with dynamic energy transfer and trolley capabilities," said Martin Cavassa, director, global business development autonomous systems, Komatsu. "The ability to seamlessly transfer power to a moving truck operating without a driver is a pivotal achievement in our roadmap toward decarbonizing mining operations and provides the pathway for managing battery-operated trucks autonomously."
