The two post lift is compelling as I can move it around. My thoughts are to have multiple bolt location in the garage.
My only concern is making sure I don't drill through the rebar. With all of the pictures I took of the place being built... this was not one of them 
For those in town that had them installed... are they bolted down and how did they know where the rebar is? I know there is atleast one architect on this thread  Once I am convinced I can solve the rebar problem I can then decide on a lift 
That or I need to start looking for land, near the DFW airport in a good school district to build a nice garage with a house attached. |
Chris,
When I built my house 5 years ago, for the garage floor, my contractor used the rebar sheet mesh. I was thinner than the rebar that he used in the main house foundation. That mesh is used all the time for garage floors. When I drilled the 5 holes for the Maxjax and then I drilled 3 more holes so all I had to do slide one column back 5" to accommodate a larger vehicle for second set up. In one of my 8 holes I actually hit the rebar mesh and it was no big deal for the drill bit to go right through it. You have to go down at least 3.75" for the drop in bolts to be below the concrete, that is what holds the columns in place, the bolts grabbing below the concrete. When you have brittle concrete, the drop in bolts can't bite and hold. Some people used concrete epoxy for added strength, I decided not to because all my bolts grabbed and easy torqued to 100 + LBS. Remember you are using a high impact concrete drill with a concrete bit, going through rebar is pretty easy.
