I wonder what my 15 year old 57' x 45' shop would cost today??
All "I" beam construction,,,,,,
The roll-up door is 18' wide. for scale
I have a couple beam clamps, but, have not used them much, because of the loader,,,
I used the beam clamps when I built the building to move the beams.
I got a trolley too, but, again, I have found zero need for it,,,,,,

in 15 years.
An engine hoist might be a better, safer and more convenient option??
That "beam" is hard to move!!
