I'd like to watch while you bend those I-Beam hoops
Sounds interesting though. Chainfall on a trolley, with some sort of
stop at the back?

Saw a somewhat similar setup once. About an 18' flatbed type trailer
that had several framed "hoops" (not bent, just welded square)
supporting an I beam down the middle and out the back a few feet. Small
chain hoist on a trolley. The rest of the trailer was outfitted with
storage for several large coils of AL stock and a forming rig for
seamless gutters.
