I have an opportunity to bid on a bridge crane, already on the
ground.

I'm happy for you, really I am.

The specs a 20 ton main lifter, 2 ton auxiliary, 77 feet span.
Made by Cleveland Tramrail.

I am trying to figure out how many tons it may be. I am coming up with
50 tons as my best conservative guess.

Do your own homework.
