The ladder idea is interesting, but remember almost everything we hang is dry except for the fringe that is just damp. The wet rugs are in our 2nd story dry room on the automated hoist.
The heaviest rugs we hang on our tallest rack are 9 X 12, which when dry range from 50-120 lbs and we always use 2 people for large ones. the vast majority are 5 X 7 amd smaller so no problem for 1. Tthe pole is hung forist in front, filled up with rugs then shifted to the rear.
Because they are dry they do not get humps in them.
