    Zoomlion’s wide-body battery trolley trucks: design notes for mine planners

    Zoomlion’s wide-body battery trolley trucks: design notes for mine planners

    First reported on International Mining – News

    30 Second Briefing

    Zoomlion is developing a wide-body battery trolley haul truck option that builds on the recent resurgence of trolley-assist systems at large open pits such as Collahuasi and Los Pelambres, which currently rely on diesel-electric trucks. The concept targets battery-electric trucks drawing power from overhead catenary on uphill hauls, using on-board batteries for off-trolley sections to cut diesel use and ramp emissions. For mine planners, this points to future pit designs and ramp geometries explicitly optimised for mixed catenary–battery operation rather than pure diesel haulage.

    Technical Brief

    • Design is intended to be compatible with current diesel trolley infrastructure while enabling later transition to full battery operation.

    Our Take

    Zoomlion already features in our coverage for deploying 40 ZT160HEV hybrid autonomous haul trucks at a coal mine in Xinjiang, so a battery trolley option signals the company is building a full spectrum of low‑emission haul solutions rather than a single flagship product.

    Collahuasi and Los Pelambres are among the Chilean copper operations highlighted in our database for major 2026‑targeted expansion and life‑extension work, so introducing trolley‑battery haulage there would likely be evaluated not just for carbon reduction but for how it supports higher throughput on constrained pit ramps.

    With Collahuasi’s recent performance issues noted in our coverage and copper prices elevated, any adoption of Zoomlion’s wide‑body battery trolley trucks at that mine would be as much about stabilising unit costs and productivity as it is about meeting sustainability targets.

    JOEST Australia’s Pilgangoora expansion order: design and wear notes for mine engineers

    JOEST Australia has secured the largest order in its history from Pilgangoora Operations Pty Ltd for the PLS P2000 Expansion Project at the Pilgangoora hard rock lithium mine in Western Australia. The contract covers multiple vibrating screens, feeders and a primary grizzly, building on JOEST’s previous scope at the site. With the P1000 Expansion Project due to complete in 2025, the new package signals further scaling of front-end crushing and screening capacity, with implications for equipment sizing, wear-liner selection and maintenance planning in high-throughput lithium circuits.

    BHP’s first Olympic Dam block cave resource: design and cave stability notes for engineers

    BHP has declared a first underground block cave resource at Olympic Dam in South Australia, reporting 10,730 Mt at 0.59% Cu, 0.19 kg/t U3O8, 0.21 g/t Au and 1 g/t Ag in its operational review to 30 September 2026. The scale and grade support long-life mass mining beyond the existing sublevel open stoping, with block caving likely to demand extensive footprint development, cave propagation monitoring and high-capacity materials handling. Geotechnical teams will be focused on managing cave stability in the complex copper-uranium breccia-hosted system and controlling subsidence above critical surface infrastructure.

    FLANDERS hybrid cabinet on Komatsu 930E at Belle Ayr: lifecycle gains for mine fleets

    FLANDERS has completed a claimed world-first installation of its hybrid-electric control cabinet on a diesel-electric Komatsu 930E haul truck operated by Eagle Summit Resources at the Belle Ayr coal mine in Wyoming. The retrofit cabinet replaces legacy electric-drive controls to address haul truck obsolescence while retaining the existing diesel-electric drivetrain. For mine operators, the approach signals a pathway to extend 930E fleet life and prepare for future higher-level electrification without full truck replacement.
