That would depend on what a lot is. If they are long cracks that don't intersect it may not be an issue. If they are short and intersect it may be a problem. The amount of steel doesn't do any good if the mix was wrong. The floor should have been sawn to releave stresses and head off cracks.
You may have to re-pour the section where you want the lift. Get a Structural engineer to guide you on the concrete cracks.
I have seen the results of a poorly installed lift and it wasn't pretty. It snapped off the floor and a man lost his foot because of it. He was pinned and there wasn't anything we could do for him until heavy rescue got there.
