Welcome to our September 2012 BMT WBM Machinery Magazine. The release of this
edition coincides with this year’s MINExpo International in Las Vegas. Preparing our
involvement at MINExpo brought us to reflect on the wide range of services and products BMT WBM provides to the mining industry. Many of these services already have a long heritage, but continue to be developed through innovation and the application of leading edge technology. It seemed high time to revisit some of these services in this forum. Articles from pages 4 through 7 follow a theme of diagnostic testing and analysis of draglines, including roller load tests, spall tests, machine house ventilation assessment, and suspended load measurement.
