How much cement support does a two post need as far as extra thickness or grade beam?
When I get my new shop built, I would like one of each (4 post and 2 post). It's not like I will be using it in a production shop and I like the idea of the 4 post being able to roll to a different location without being bolted to the floor. I think the 2 post would be a little more handy for working on vehicles, but I think I will get a 4 post lift first so I can move it around.
