anybody know about 2-post hoists?

Oh I installed mine using a engine lift and some help from my son in law. Your going to have to check how thick the concrete is where you want to mount it. I poured a slab 20' x 60' and where I put the lift I went over board and pour it at that point 12" thick 4'x 20'. Make sure you get the risers for the pads for use on a truck.
