U&M Mineração e Construção S/A, an earthworks contractor in Brazil, ordered 30 Rolls-Royce MTU Series 4000 engines to repower its existing fleet of mining trucks and excavators. The engines are expected to improve the performance, profitability and sustainability of the machinery, Rolls-Royce reported.

U&M will be using the MTU engines in both Komatsu 930 mining trucks and Hitachi EX5500-6 mining shovels.

U&M said repowering the excavators with MTU Series 4000 engines has never been done before. “The move improves the performance, reliability and cost-effectiveness of the machinery and reduces the logistical effort needed to support the machinery,” Maricio Casara, commercial director, U&M, said.

The order follows one placed by U&M in 2019 for 20 engines.

“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,” Casara said. “Also, we prefer to have the same engine type powering both our load and haul machines.”

Rolls-Royce said the order speaks to the company’s ability to support remote sites. “They are operating in one of the remotest regions of Brazil under very challenging conditions, making their choice a special accolade for our engines and services,” Carlos Levy, managing director, MTU engines, Brazil, Rolls-Royce, said.

The 30 engines will be delivered in 2020.
