We are very pleased with the productivity improvements we are getting. We are getting around 20% over and above what we would get from a regular fleet of trucks of the same type.” The fleet now consists of 47 Caterpillar Command for Hauling 793F CMD autonomous trucks, supplied through Cat dealer WesTrac. “These trucks don’t need to stop to change drivers, clean windscreens and do those sorts of things,” Power said. “The big gain in them is that they can drive at higher speeds in all conditions and that they only need to be stopped when they are being maintained or refuelled. We can do more work with fewer trucks so there is a saving in terms of capital. A key part of this has been developing that relationship with Caterpillar and WesTrac because it does take a lot of work from the vendor and the dealer to do this.” Caterpillar’s Global Head of Mining Denise Johnson was also quoted, saying the Caterpillar 793 had proved to be very productive for remote operations. “We started with that model because we felt it was the sweet spot but we do have intentions of expanding that size truck,” she said. “It’s not the largest but it is one that is very heavily used and is in many remote fleets. The trend is fewer people, less interactions between people and machines, but there are certain elements of site management where human intervention won’t go away completely.” The other Cat autonomous truck customer, BHP Billiton, has been trialling 12 Command for Hauling 793F CMD driverless haul trucks at its Jimblebar iron ore mine. WA Iron Ore Asset President Edgar Basto Basto said in The West Australian that the truck program was making good progress but that the project would be assessed by the end of the year. However, BHP Billiton is moving ahead rapidly with its blasthole drill automation program. Atlas Copco recently won an order from BHPB for autonomous drill rig upgrades to be used at iron ore mines in Western Australia. The order, which follows a two-year trial, is for upgrade packages to 18 drill rigs. It also includes two machines already operating autonomously. The 20 Pit Viper 271 autonomous
