I'm trying to find an article with the exact story, but during the building of some of the early large satellites (something like the MilStar satellites [0][1]) they realized it would be really handy to be to rotate the satellite to work on it from different angles. So the satellite manufacturers repurposed rotary train car dumpers [2] in order to rotate the giant satellites.
