Komatsu, Cummins reach milestone with 100th engine delivery to Rio Tinto

Rio Tinto has received delivery of the 100th repower engine component for its Komatsu 830E and 930E haul trucks from the original equipment manufacturer (OEM) and Cummins.

The Cummins QSK60 modular common-rail system (MCRS) advantage plus engines are capable of generating higher horsepower with fewer turbochargers and can also be used for Komatsu autonomous trucks.

Service life between repowers is predicted to be 36,000–40,000 hours, up from 28,000–36,000 hours, delivering lower lifecycle costs.

The 100th handover was celebrated at Komatsu’s Welshpool facility in Perth, where its mining equipment is prepared before transport to customers.

“Apart from being the 100th MCRS module delivered, the date of the installation – May 27 – is exactly 560 days since we delivered the first MCRS module in November 2017,” Komatsu project support manager for Rio Tinto’s engine module program Andrew Hardy said.

“And from the installation of the first MCRS engine module, Rio Tinto’s dump trucks have been in service with this new engine configuration for more than 26,500 days cumulatively across the fleet, with the first truck being in service for 555 days as of May 27, 2019 – the day this 100th module is installed in the truck.”

This year is also Cummins’ 100th anniversary, and to mark that significant milestone this latest engine has serial number 9800100.

Rio Tinto, Cummins and Komatsu have been working together since mid-2017 to see the Komatsu haul trucks operating in the Pilbara region of north Western Australia upgraded with the latest technology.

“Working together, the three partner companies in this project are facilitating additional resource requirements for the economy of WA, which in turn is helping generate additional jobs, along with enhanced job security for those already involved with the engine rebuild and install project,” Komatsu general manager western region Glenn Swift said.

Rio Tinto, Komatsu and Cummins also celebrated the arrival of the engine to site by raising $19,400 for the mental health support service, Beyond Blue.
