I am very much not an expert.
You can, assuming you can get the manufacturer of the lift, probably get
their floor specs off their website or call them to get them.
IIRC, most of the ones I've seen for a 2 post lift are 6" concrete, with
some psi rating (not sure if that rating is higher than a "normal" garage
floor).
That doesn't mean you can't do it... You just might need to have a section
of the floor cut out and repoured. This isn't all that huge a deal.
Also, I think the requirements for any two post lift will be similar... I
don't think a commercial 2 post will be any different than a lighter duty
2 post, given the same weight on the lift itself (i.e. the 10k lb rating
may dictate a better floor, but unless you have 10k on it, the floor
rating for the 7k light duty version will work).
Again, not an expert. And if it was me, I'd also be pretty concerned
about a 4" floor with a 2 post lift.
