At MINExpo 2012, Caterpillar will have the largest single exhibit in the history of the show at its booth, which also happens to be the first heavy-haul locomotive to be displayed at MINExpo. The 4,831 m2 Caterpillar exhibit features 18 complete mining and support machines and myriad components, models and technology displays “representing the broadest mining product line available and the most extensive customer support system in the world” according to the company. Unique among all machines within the Caterpillar exhibit and throughout the hundreds of MINExpo displays, the Electro-Motive Diesel (EMD) SD70ACe locomotive-decked out in Caterpillar yellow-will give the mining world an opportunity to explore “the railroad technology that transports minerals to market.”
At 190,000 kg, the massive locomotive sits alongside some of the largest mobile equipment in the world. EMD introduced the 3,243 kW diesel-electric SD70ACe model in 2005 for heavy-haul freight applications worldwide. The locomotive integrates EMD’s 16-cylinder 710 engine, EM2000 microprocessor control system and AC traction. Safety features include the crashworthy designed QuietCab, compatible with all cab signalling and safety systems. The SD70ACe also offers simplified maintenance and a longer maintenance interval. It also provides advanced diagnostics and remote monitoring capabilities. In fuel-efficiency it provides more than 230 tonne-kilometres per litre. The EMD locomotives themselves are durable, lasting 40 years or more, and can be rebuilt reusing 80% of the core components to extend the locomotive life. Caterpillar states that SD70ACe locomotives operate in mining operations across the globe, including the US, Canada, South America, the Middle East, Africa and Australia. Users include BHP Billiton Iron Ore and Fortescue Metals Group in Western Australia, and Quebec North Shore and Labrador Railway, owned Rio Tinto iron ore operation Iron Ore Company of Canada (IOC).
