    McLanahan feeder breaker maintenance: reliability and wear insights for mine engineers

    McLanahan feeder breaker maintenance: reliability and wear insights for mine engineers

    First reported on Australian Mining

    30 Second Briefing

    McLanahan is promoting structured maintenance strategies for its feeder breakers, which combine controlled chain-feeding with primary size reduction for underground and surface coal operations. The company stresses regular inspection of pick segments, conveyor chains and flight bars, plus correct torqueing of gearbox and drive couplings, to prevent unplanned downtime on high-impact duty cycles. Guidance focuses on planning component change-out intervals around known wear patterns and ensuring OEM-spec parts and clearances are maintained to protect motors, gearboxes and crusher rolls in abrasive, high-throughput environments.

    Technical Brief

    • McLanahan designs housings and frames for repeated impact loading from oversize and tramp material.
    • Shear-resistant chain and flight assemblies are specified to cope with abrasive coal and stone contamination.
    • Drive trains are arranged for low-speed, high-torque transmission to minimise stall events under surge loading.
    • Segmented pick drums allow localised replacement of worn sections rather than full-drum change-out.
    • Guarding and access platforms are integrated to permit inspection without exposing personnel to rotating components.
    • Structured maintenance regimes on these breakers are presented as a template for other high-duty coal-handling assets.

    Our Take

    McLanahan’s repeated appearance in our Australia-focused safety and product coverage suggests it is positioning itself as a lifecycle solutions vendor, with feeder breaker maintenance content complementing its earlier push on filter presses and QUICKCHANGE cloth systems for brownfield plants.

    For Australian operators, combining disciplined feeder breaker maintenance with the kind of dewatering and tailings upgrades highlighted in the December 2025 McLanahan piece can materially cut unplanned downtime at both the face and the plant, which is where most productivity losses show up in our mining case studies.

    Within the 698 tag-matched safety/product items in our database, relatively few focus on OEM-led maintenance practices rather than new hardware; this gives McLanahan an opening to influence site standards and lock in long-term service relationships across Australian mines.

    Boliden Somincor–EDP–Greenvolt solar UPAC: integration notes for Neves‑Corvo mine engineers

    Boliden Somincor has partnered with EDP and Greenvolt to build Portugal’s largest self‑consumption solar generation unit (UPAC) near the Neves‑Corvo zinc mine at Castro Verde, supplying power directly to mine operations. The distributed solar plant will sit adjacent to one of Europe’s largest zinc orebodies, reducing grid dependence for high‑load processes such as hoisting, ventilation and paste backfill plants. For mine planners and electrical engineers, the project signals growing integration of large‑scale on‑site renewables into base‑metal underground operations in southern Europe.

    Aramine AutoNav Tele loader at Reward Gold mine: design and safety notes for planners

    RCT – Powered by Epiroc’s AutoNav Tele automation has been fitted to an Aramine L350D loader to support narrow vein stoping at Vertex Minerals’ Reward Gold mine at Hill End, after the unit was commissioned through Epiroc’s Orange Service Centre in New South Wales. The compact L350D, designed for ultra-narrow headings, is now operated via tele-remote AutoNav control rather than line-of-sight, allowing tramming and loading in constrained drives. For geotechnical and mine planners, this enables extraction in thinner ore lenses while keeping operators out of unsupported ground.

    Bosch Rexroth–MEDATech off‑highway electrification: integration notes for mine engineers

    Bosch Rexroth is partnering with MEDATech Engineering to deliver end‑to‑end electrification packages for off‑highway and mining mobile equipment, combining Rexroth’s mobile hydraulics, inverters and controls with MEDATech’s EV drivetrain integration capability. The collaboration targets full systems from componentry and software through to application‑specific design and build, aimed at OEMs and retrofit projects for haul trucks, loaders and other heavy units. For mine operators, this points to more standardised electric powertrain architectures and a clearer route to integrating high‑voltage drivetrains with existing hydraulic and control systems.
