Komatsu–ABB dynamic energy transfer: haul road and power design notes for engineers
Reviewed by Tom Sullivan
First reported on International Mining – News
30 Second Briefing
Komatsu and ABB are expanding their dynamic energy transfer concept beyond conventional trolley-assist haul trucks, with a new “side arm” current collection system in development for demonstration at Komatsu’s Arizona Proving Grounds in the US. Announced by Lucas van Latum and Nic Beutler at The Electric Mine 2026 in Lisbon, the side arm aims to maintain high-power DC transfer to mobile equipment without requiring trucks to remain strictly under overhead catenary. The work signals a push towards more flexible on-route charging layouts, with implications for haul road geometry, overhead line placement and mine power distribution design.
Technical Brief
- Dynamic energy transfer work builds on ABB’s existing trolley and e-drive power electronics architecture for mining.
- For other mines, outcomes will inform design envelopes for future on-route charging and overhead line standards.
Our Take
Komatsu features repeatedly in our recent mining coverage, from Mine 4D deployment at Boliden’s Kevitsa to autonomous truck retrofits at Norton Gold Fields, suggesting this dynamic energy transfer work with ABB is another strand in a broader push to integrate digital, autonomy and power systems across its fleet.
Locating part of the joint Komatsu–ABB work at the Arizona Proving Grounds in the United States gives them a controlled, grid-connected test bed in a major mining market, which can shorten the path from prototype energy-transfer concepts to commercial offerings for North American operators.
