News to me. Possible I'm sure but at what trouble and expense?
Just dragged home a 10 yr old 9K pd Bendpack 4 post. Been studying it a bit as I try and figure out how to get it off my car trailer. (seller was able to load it fully assembled onto the trailer for me, but was setup with some pretty heavy equipment)
Much of the lift mechanism is under (and attached to) the right side ramp. Even redesigning and relocating all that the ramps themselves are long and heavy!
As I stand there and look the mechanism over I'm reminded of force vectors from college. Someone had a good time figuring that all out for one of these.
Converting to an arm style lift would significantly change much of that.
When my wife and I recently moved to a new house I found myself in a pickle with how to move my new 4 post lift.
If you already have it on a trailer, the way we got ours down was with a cherry picker, one end at a time. The trick is to keep it balanced and make small adjustments as necessary. It was just the two of us and it went smooth as silk.
