Bis Industries says it has reached the next stage in the commissioning process of its innovative HUGO underground mining truck – Proof of Concept testing. Last week HUGO was loaded up with payloads of 80 t, testing the diesel electric hybrid power train in a range of situations to mimic underground hard rock mining haulage. HUGO stands for Hybrid Underground Operations.

The company outlined key reasons why HUGO is disruptive in this market – first off of course it brings a 40% increase in productivity compared to today’s largest available 60-65 t trucks. It also meets the current need for lower emission solutions, while providing a platform for decarbonisation and development in using alternative energy sources.

In operation it says it delivers a 50% increase in speed-on-grade capability. A 25% increase in payload results in 25% fewer truck movements and interactions; plus it has to potential to bring approximately 15-25% less overall haulage costs. Bis added: “We’re looking forward to seeing this low-cost-per-tonne hybrid haulage solution take charge underground.:

The truck had already been put through its paces at a quarry during including extensive durability testing to test the robustness of its electrical system. It has also undergone shake/vibration testing on rough rutted surfaces (mirroring conditions underground) together with running continuous laps to verify its hydraulic system performance.

HUGO’s engine, supplied by Volvo Penta, can use HVO fuels derived from waste materials like residue oils and fats, reducing HUGO’s carbon footprint even further and broadening its range of application. The design also means users don’t have to change the way they mine, as rather than being all battery powered, it is equipped with an advanced hybrid electric powertrain technology supplied by Danfoss Editron.
