I will note, that I had a potentially life threatening occasion, using four of these to move a mill across a floor that was NOT nearly as level as it felt when walking over it.
Nothing to get yer heart going, like seeing one of the skates decide to outrun the milling machine it was supposed to have perched upon it. It came to nought but very accelerated heart rates, but I figure its worth passing the experience on. I figure wiring the skates in place, or simply arranging a couple layers of foam rubber between the skate and the machine tool, would have saved us a LOT of existential Angst that day!
We were moving slowly enough that we were able to stop it in place as soon as the skate, well, skated out, but we all saw the possibilities!
Think the move through, plan around what escape route you might need in a 'falling machine' situation. Dead is a long time, so is Crippled! Stay safe
Took me a couple afternoons to level when I first got it.
