McLanahan feeder breaker maintenance: reliability and wear insights for mine engineers
Reviewed by Tom Sullivan

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.
