    The machine that shows up about 3 seconds in looks to me like a manual piledriver, uses pulleys and cranks yo pull the weight up, then just gravity to drop it down the track.

      Kinda does, yeah, but it’s only put into place after all the piles are in! Maybe they have one of those anchored on a boat or something?
