The trays are tailored to Bravus' fleet of CAT796AC haul trucks and to help maximise production and improve operational efficiency.
Bravus CEO David Boshoff said the company was keen to capitalise on SMW Group's 20 years of experience servicing central Queensland's coal fields.
"There's an extensive mining services knowledge base in our region, and it has always been our intention to use this and work with businesses based in central Queensland wherever possible," he said.
"The Ultrahaul tray is a class-leading product for mine haul trucks that SMW Group has developed specifically for the central Queensland coal industry.
"We have been impressed by SMW Group's willingness to work with us to get the product right for our operations and look forward to seeing the results of this relationship over time."
SMW Group chief operating officer Frank Humphreys said the contract was a great result for the company and Central Queensland manufacturing.
"Securing a contract to supply Ultrahaul trays to the Carmichael project is a great outcome for SMW Group and is a vote of confidence for central Queensland's mining services industry," he said.
"We are excited to be involved with a high-profile operation like the Carmichael project."
Boshoff said the contract would have direct benefits for Mackay and Rockhampton, bolstering the local economies against the impacts of COVID-19 restrictions.
"Having this level of manufacturing capacity in our region is a huge boost, because we can continue to grow our fleet and ramp up operations with minimal impact from COVID-induced restrictions and border closures," he said.
"We are proud to have made good on our promises to Queensland, and especially regional Queensland. We have created more than 2600 jobs and signed more than $2.2 billion in contracts.
"More than 88% of our contracts are being delivered in Queensland.
"We are ramping up our mining fleet and construction on the coal handling and processing plant is well underway. We are excited to be so close to delivering on our promise to ship first coal this year."
