Following a bearing defect from stage 1 to stage 3 on a mine-hoist gearbox.  The presentation will cover the basic concept of HD Technology and how the HD technology can extend the pre-warning time dramatically. A mine hoist is a mission critical application in underground mining and the challenge to measure bearing condition is the low RPM (52 RPM) and the limited measuring time window (120 seconds). An innovative tool to show information from several thousand spectrums in one picture will be demonstrated among other advanced tools.
