With Cat equipment built to perform over multiple lifetimes, the Cat Certified Rebuild was an efficient way to help get an economic value out of the original asset investment.Ī Cat Certified Rebuild (CCR) is a full machine rebuild that provides a like-new machine, inclusive of all Cat updates to help achieve a full machine life supported by the Caterpillar warranty. They’re also quieter, making them a little more comfortable for the operator.” “Our like for like material movements are now done with significantly less fuel which is a great environmental outcome. “This in turn allowed us to remove Dozer 79 out of production, and into the workshop to complete a Cat Certified Rebuild.”Īlongside the increase in machine availability, this project presented a budgeted fuel burn reduction of up to 25%. “Recent success with repowering our D11 fleet with C32 engines, has helped our mining operations move more bauxite due to increased power in the machine.” This incorporated replacing the 3508 engines that the machines originally came out with, with the newer C32 engines. In early 2020, the Hastings Deering team worked with Rio Tinto on an innovative alternative solution for engine replacement in their D11R fleet that reduced costs, fuel use and emissions while extending lifespans.

One of the key projects that helped to allow for the 9-week Cat Certified Rebuild was the D11R repower project. “By planning large maintenance projects in advance, at Rio Tinto, we’ve been able to compensate for machinery downtime and achieve some great energy efficiencies.” “With a 24/7 operation, we need to plan and strategically think about our assets, their maintenance and lifecycle.” Rio Tinto knew that it wanted to undergo a Cat Certified Rebuild for its dozer but had to come up with an innovate way to do this while minimizing equipment down time.īrendan Coleing, Superintendent, Mining Maintenance said that the Gove Operation has focused heavily on building safe and reliable machinery to meet the targeted life of their assets and maintenance schedules.

When that asset is a Cat D11T dozer, strategic forward planning is critically important. In any operation, the need to remove a key asset for 9 weeks makes a significant impact on delivering on production targets.
