garage hoist i-beam size requirement
(OP)
I want to install a hoist in my garage that is rated for 800 lbs maximum load. The span across the garage is 13 feet. What size I-beam should I be using?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: garage hoist i-beam size requirement
I have assumed you are using mild steel for constructing the hoist. After calculating the bending stress, and finding the section modulus, the I-beam should have the following dimensions.
TOP & BOTTOM FLANGE = 175MM
TOP & BOTTOM FLANGE THICKNESS = 10MM
MIDDLE WEB = 12MM
TOTAL DEPTH OF I-BEAM = 300MM

Also, don't forget to size the support columns at each end of the hoist beam.
RE: garage hoist i-beam size requirement
I would start with S6X TBD; assuming it is simply supported at the ends only and factoring lateral load due to impact (biaxial bending must be considered. I really do not think it is a good idea to post final sizes due to many unknowns. Hoist suppliers do recommend beam sizes to their clients (or at least the bottom flange dimensions that would work with their trolley wheels).
I would consult a local engineer to verify the results and also you need to ensure that the supports (masonry walls, columns etc. are adequate).
Good luck

I = x in^4
Conservative simply supported
Deflection = (PL^3)/(48EI)
or
Fixed ends
Def = (PL^3)/(192EI)
where L is you span
Wouldn't go over .125 max deflection
