Not to take anything away from that idea but it looks cumbersome and seems like it would be difficult to maneuver around under a lift because the footprint is so large and how the weighted boom extends so far out. .
This thing works extremely well and it's bulk is not a real problem. I'm not that spry, anymore at 71 I have arthritic like issues. You also have to consider the cost. I had the hoist, and it is made of scrap. Biggest issue for me is that I don't have a shop so I must use the tracks to allow it to roll. I also have a HF hydraulic trans jack, but cannot use it on the dirt. I do use it for other things, like putting pressure under an A-arm when doing front end work, etc.
