U&M will use the new MTU 12V 4000 C03 engines to repower a fleet of mining trucks and excavators, and to improve the performance, profitability and sustainability of the machinery. The 30 engines are to be delivered in 2020 and are in addition to 20 of the same engines ordered by U&M in 2019.

Carlos Levy, Rolls-Royce's managing director for MTU solutions in Brazil, said: "We are proud to have once again convinced U&M of our MTU solutions for the mining sector. They are operating in one of the most remote regions of Brazil under very challenging conditions, making their choice a special accolade for our engines and services."

Mauricio Casara, commercial director for U&M, said: "Already having MTU engines perform reliably in part of our fleet played an important part in our decision to repower additional machinery with MTU engines. Also, we prefer to have the same engine type powering both our load and hauling machines."

U&M will be using the MTU engines in both Komatsu 930 mining trucks and Hitachi EX5500-6 mining shovels. It is the first time these excavators are being repowered with MTU Series 4000 engines. The company expects that the move will improve the performance, reliability and cost-effectiveness of the excavators and reduce the logistical effort needed to support the machinery.

Brazil is a growing market for MTU mining engines. Soon, more than 100 MTU engines will be running in mining applications all over the country, supported by local service partners.

Rolls-Royce plans to present its MTU drive and power solutions for the mining sector at MINExpo International in Las Vegas, US from September 28-30.
