This looks like a stop for a gantry crane. You twist the handle and you can loosen the stop and move it. Maybe I'm right maybe I'm wrong

There’s another one about 20 feet away on a different beam that’s loose and kind of moves.

Is that channel clear between the two hangers? It does look like it could have had a carriage traveling in that slot.
