Hey Tom, You're gonna need a heck'uva beam to carry a ton over a 40' span... I wanted build a similar hoist for my shop (but with only a 24' span), but couldn't justify the cost... so I'm going to build the A frame contraption. My A frame will be 13' to the top of the beam and 12' wide... wanted to be able to support about 2500#. Just so happens I work with an engineer who did the calculations for me. For that configuration, I need an "S" beam (standard), 8" x 19 lbs/ft. This set-up will allow about 500# for trolley, chain hoist & rigging, and allow me to safely lift a ton... this system provides a safety factor of 3. As others have stated, probably best to consult an engineer. regards, DL
