    Bradken Liebherr R996B undercarriage at Queensland coal mine: cost and wear insights for engineers

    November 4, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    Bradken’s excavator undercarriage solution for the 672‑t Liebherr R996B is being benchmarked against a low‑cost competitor on two separately owned units at a Queensland coal mine, with Bradken reporting a significant performance gap in its favour. The trial compares full undercarriage assemblies under similar coal overburden conditions, focusing on track shoe and component wear life, maintenance intervals and downtime. Results point to longer service life and reduced change‑out frequency for the Bradken system, with implications for total cost per operating hour on large mining shovels.

    Technical Brief

    • The two machines are operated under different ownership, with one undercarriage using Bradken’s undercarriage solution, chosen based on Bradken’s reputation for performance rather than lowest upfront cost.
    • The competing system is described as a “low‑cost competitor”, framing evaluation around lifecycle value, not purchase price.

    Our Take

    Bradken’s focus on undercarriage performance at a Queensland coal mine lines up with its SmartRoller™ temperature-monitoring work, signalling a push towards condition-based maintenance on large excavators rather than periodic visual checks.

    In our database, Bradken’s recent investments in Western Australian refurbishment capacity and the Chilca (Peru) wear-parts foundry suggest it is positioning as a full-lifecycle support partner for heavy equipment fleets, which would make Liebherr R996B undercarriage solutions part of a broader service offering rather than a stand-alone product.

    Coal is only one of several commodities touched by Bradken’s recent projects, but using a high-duty Queensland coal operation as a reference site gives the undercarriage solution credibility in some of the harshest load and abrasion conditions in the Mining corpus.

    2027 PDAC Awards: key project and sustainability lessons for mining teams

    PDAC has named six recipients of the 2027 PDAC Awards, recognising achievements spanning early-stage discovery, major mine development and sustainability in Canadian and international projects. The awards cover categories such as mineral exploration, mine builders, sustainability and indigenous engagement, with winners typically selected for discoveries that add multi-million-ounce gold or multi-million-tonne base metal resources and for projects that reach commercial production on time and budget. For engineers and geoscientists, the list signals which exploration models, development strategies and community partnership approaches are currently being held up as best practice.

    Putzmeister Underground–Cannon Mining Mexico deal: fleet support gains for mine engineers

    Putzmeister Underground Division has appointed Cannon Mining Latin America as its exclusive distributor for Mexico, covering shotcrete equipment, concrete transporters and other specialist underground mining solutions. The deal aims to expand parts and service coverage across key mining regions such as Sonora and Zacatecas through Cannon’s local workshops and field service teams. For mine operators, the partnership should shorten lead times for fleet support and commissioning of new underground concrete placement systems, reducing reliance on imports and remote technical support.

    Epiroc Autonomous SmartROC D65 MKII drills: deployment lessons for mine engineers

    Epiroc’s fleet of Autonomous SmartROC D65 MKII blasthole drills is expanding across mining and quarrying, with units now running at Fortescue’s Solomon and Eliwana iron ore operations in Australia and at Luck Stone’s Rockville quarry in the United States. The rigs automate drilling cycles for production blastholes, delivering repeatable hole depth and spacing and reducing operator exposure at the bench. For engineers, the deployment signals growing acceptance of OEM autonomy for large-scale production drilling rather than limited trial use.
