    Komatsu–ABB dynamic energy transfer: haul road and power design notes for engineers

    Komatsu–ABB dynamic energy transfer: haul road and power design notes for engineers

    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.

    Sandvik underground fleet at Kamoa-Kakula: haulage and maintenance lens for engineers

    Sandvik has secured an order from Kamoa Copper SA for 19 Toro® underground trucks and loaders for the Kamoa-Kakula Copper Complex in the Democratic Republic of the Congo, taking the site’s Sandvik underground fleet to more than 100 units. The equipment will support one of the world’s largest underground Sandvik fleets at a single mine, operated by the Ivanhoe Mines–Zijin Mining joint venture. For engineers, the scale signals sustained high-volume, trackless underground haulage and significant long-term demand for OEM parts, maintenance capacity, and fleet management systems.

    Metso Durarok™ primary sizer at Yenipazar mine: design and throughput notes for engineers

    Metso has secured a €25 million order from Aldridge Mineral Madencilik A.Ş., part of CVK Mining, to supply key minerals processing equipment for the Yenipazar polymetallic mine in Türkiye, including one of its first Durarok™ primary sizers. The package, booked in Metso’s Minerals segment for 2026, will support primary crushing and downstream processing for a deposit containing multiple base and precious metals. For engineers, early adoption of the Durarok™ sizer at Yenipazar will be a reference case for hard-rock primary sizing performance in Turkish conditions.

    Volvo Autona / earth autonomous haulage: key takeaways for mine planners

    Volvo Autonomous Solutions has launched Autona / earth, a commercial autonomous haulage system for mines and quarries built around an autonomous Volvo FH truck and an in-house developed virtual driver. The package is delivered as Transport-as-a-Service, with Volvo providing the vehicle automation stack, site infrastructure, operational support and maintenance rather than selling trucks outright. The system is designed to plug into existing mine haulage operations, signalling a shift towards OEM-managed autonomous fleets where OEMs assume more responsibility for uptime and performance.
