Hoping to install a two post hoist in the new year. It will be installed on a slab that I have no idea about. Has anyone else done this and if so, how can I be sure the concrete is up to the task. I have considered cutting through the slab for the two bases and digging for some decent footings, tie in to existing slab and maybe even inset a bolt plate before pouring the boxes. Might sound like overkill but there must be a fair load at the base of the posts when lifting cars.

Thoughts?
