I am half way through installing a Derek Weaver Pro10 certified lift. This lift is pretty impressive so far.
Consider: just because your lift can support 10k doesn't mean your concrete can

This. If your concrete isn't thick enough, you're going to have a bad day.
With that said, I don't own a lift, but I have used the Atlas lifts numerous times without issue. They are nice lifts for the money. However, after using a lift with the posts rotated about 45* rearward, the extra door clearance is super nice.

Unless you have pretty old concrete, you likely won't have an issue with the PSI rating. Anything that is in good condition should be fine; I've never read anyone saying their concrete failed if it was thick enough. And I don't even know how one would "measure" the PSI of their concrete, unless you actually stressed it to failure. I think that's more a rating the manufacturer gives to cover their own butt.
As for the concrete thickness, you can drill a pilot hole where you're going to mount it to get an idea of what you have. Most garages in my area have at least 4" (which is usually minimum for most lifts, but obviously check for the one you're getting), but the thickness can vary in some areas and go down to 3"-ish. However I doubt you could "accidentally" mount it on concrete that's too thin - from what I've read the thickness requirement is so the anchors have enough to bite into, and those that have tried to mount them in shallower concrete couldn't get torque on the anchors.
In the case where you don't have enough, I have seen people on GJ forum that cut out an area to poor thicker pads where the lift is being mounted, and just tie those pads back into the main slab with rebar. It's a bit more of a hassle, but it is do-able.

Getting ready to improve things in the garage.
The main component that the garage will be rearranged around is a car lift.
I definitely need a 2-post post lift.
This thread is very helpful for me. Thank you very much for your reply.

I got to do a walkthrough yesterday to the new house I'm having built. I noticed that the 3 car garage has 12-14 foot ceilings and a 4" thick foundation.
I'll be shopping for a lift soon as well.
