Very nice and simple. I like the tag line set up. On some of the early 1900's machines I've been around: I saw a weight that runs up and down a track on the boom this was on a Erie steam crane. My buddy has a Insley half swing machine he's starting restoration on and it has a pipe with a pully on top where a weight just slides up and down inside the pipe,but that was probably for the trip rope when it has a shovel front mounted.
