LOL, as usual you're going macro (larger wheels)when I'm thinking micro (smaller wheels)Frank. Although for working outside the shop on dirt you've got a point. Would be really interesting to see how "tippy" this is. I was thinking how easy it would be to convert my HFT engine hoist to this but would need one of the air powered Rams like has been mentioned. In a lot of ways it might be easier to maneuver than an engine hoist. But it looks like the tilt head on the boom is crucial to balance. I would have been very interested to see the setting down of the fridge on the platform as it got chopped off the vid. While it's easy to grasp the concept I'll bet the devil is in the details.
