One of the key projects that helped to allow for the nine-week Cat Certified Rebuild (CCR) 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,” he said. Rio Tinto knew it wanted to undergo a Cat Certified Rebuild for its dozer but had to come up with an innovate way to do this while minimising equipment down time, Hastings Deering said.īrendan Coleing, Superintendent, Mining Maintenance, said the Gove operation has focused heavily on building safe and reliable machinery to meet the targeted life of its assets and maintenance schedules.
For Rio Tinto, Dozer 79, had built up over 37,000 hours ripping and pushing bauxite at its open-pit operation. The Cat D11T dozer is purpose built to move more material and ensure maximum availability through its planned life cycle, the Caterpillar dealer says. Hastings Deering has been sustain output at Rio Tinto’s Gove bauxite open-pit operation in the Northern Territory of Australia by boosting engine power during the rebuild of dozers. National Group secured the first of these dozers earlier from Cat dealer Hastings Deering as part of an order that would see six of these machines hauled by its National Heavy Haulage subsidiary. The first new generation D11 dozer in the world started work at BHP Mitsubishi Alliance’s (BMA) Blackwater coal mine in Queensland, in 2019. The unit comes with new load-sensing hydraulics, high-horsepower reverse and the latest technology to provide higher material movement at a lower cost per tonne.
Time-saving service updates reduce daily maintenance and boost machine uptime. The mine, owned by Stanwell, has a 7 Mt/y thermal coal capability and is in Queensland’s South Burnett Region.Įngineered to be rebuilt multiple times, the new D11 has a redesigned main frame delivering lower total cost of ownership over the life of the machine, Cat says.

Stanwell’s Meandu coal mine in Queensland, Australia, has taken delivery of a new Cat D11 dozer from local distributor Hastings Deering.Įnsuring safe and efficient operation, the dozer provides operators with full command, as well as delivering higher productivity at lower cost, Stanwell said.
