We had one drive some piles for a bridge we were building, one of the most amazing systems I have seen. They started it by hoisting the ram up to the top and tripping a release, the "piston" fell and bounced on compression to start. I think you could count the revolutions with a sundial, maybe 10 or so a minute.
