I wanted to reach out and tell you how much i love this lift. What we dont use as part of the structure we do not use the plywood as a t beam to increase the capacity of the joists instead the plywood is the diaphragm.

Sorry if this is not in the correct place.
Engineered floor joist vs 2×12. 4 2x12s can span 9 1 in a 36 foot wide building and 10 2 in a 28 foot building so to interpolate split the difference 4 2x12s should be able to span 9 7 according to code. If the span was say 4 or 5 feet max before being supported by a girder then yeah a 2×4 should be okay. Already done two projects on my late model corvair that would have been a real pain with floor jack and stands.
Since i want to clear span the whole floor no poles i know im looking at needing a beefy ridge but i dont know. 2×4 are fine if span was like under 5 ft. Title pretty much says it all.
For various reasons i want to use a ridge beam and rafters vs trusses. Im building a 24 x 24 garage.
