I was thinking the yoke thing with the chain on it looked more like a small crane for putting the wheels in position to be bored. Or are we looking at a different part of the machine?

Potentially and logically a crane yes. It's perspective is misleading, examination says it could be long enough to reach centerline, making aforementioned fixturing all the more effective, not tying up overhead crane, forklift etc. Hanging ~900 pounds from center isn't such a small crane for manual handling; there is a spool of chain at the end.
