Standardization Keeps Mine Trucks Moving - BHP

The haul trucks at the BHP Mitsubishi Alliance Daunia metallurgical coal mine in Queensland Australia shift around 226 tonnes of coal or overburden every load. The fleet of 16 trucks run 24 hours a day and each truck needs to be serviced every 250 hours, or about every two weeks. The time it takes our maintenance team to service trucks is critical to our mine efficiency and productivity because it directly impacts how long they are out of action. And it is vital they are serviced safely, effectively and consistently.

That’s why we are excited about some recent improvements in the service time for the truck fleet. We reduced the average truck downtime for a regular truck service from two hours to just 40 minutes. That’s a saving of one hour and 20 minutes for each truck a fortnight, or a potential 10 hours of extra work each week for the fleet. We did three things to transform our work: introduced a dedicated service bay; allowed maintainers time to set up tooling and service kits before the truck enters the workshop; and introduced technology to design, monitor and improve the way we work.

The results have exceeded our team’s expectations. We reduced the average truck downtime for a regular truck service from two hours to just 40 minutes. That’s a saving of one hour and 20 minutes for each truck a fortnight, or a potential 10 hours of extra work each week for the fleet.
