Ah the Johnson bar. Brings me back to the days of my time at the University machine shops I worked at in college. With a bunch of big, strong, not overly bright 20 somethings and some Johnson bars you could move absolutely anything. I was once moving a piece of machinery with someone else with each of us having a Johnson bar, I think it was huge pump of some sort, and his bar slipped, putting the whole weight on my bar. I ended up doing a Benny Hill and was flipped up a few feet in the air, somehow landing on my feet. I was rather proud of that at the time. Thanks for bringing back the memory
When I need to move a heavy machine I use my 17, 20, and 26 year olds. Big, strong, and still at the age when they try to out-do each other. I used to be like that. Actually, I probably am still like that more than I would admit.
The pry bar you first describe almost sounds like a huge tire mounting bar for breaking and setting the beads on a tire machine.
