Hey Erick, is this what you used to install your lift?

i think that's his nickname at the gym!!

 

I really have no idea since I paid a professional to install my lift. Looks like those would work well though. Each of the nuts holding my lift down is torqued to 150 lb/ft so you'd need at least a 3/4" anchor to accomplish that. I just checked and the studs holding my lift down are pretty close to 3/4" diameter, so he probably used a bigger anchor. Also, the video there reccomends drilling to a specific depth before installing the anchor. My guy said it's a better idea to drill right through the concrete till you hit gravel. That way if you remove the lift or move, you can just hammer the studs into the ground and call it a day. Made sense to me... so I had him do it that way.

 

That is exactly what you use

Do you know how deep the cement is in your garage ? You might want someone to take a look before you purchase the lift

 

Why Scott? How thick does it have to be to make sure the anchors will hold?

 

It's not that the anchors won't hold, it's a question of whether the slab will support the weight of the lifted car. There's specs regarding the thickness and quality (psi) of the concrete.

If your slab isn't up to spec, you can probably cut out squares, dig down to the prescribed depth, and pour footers for the lift. Kind of like the footers under the posts in your basement. Those posts don't rest on the 4" slab, but rather on piers of concrete several feet down.

Since a failure of the lift while you're under it would be unpleasant, I would pay attention to the manufacturers recommendations.

 

Thanks for that info. I know the concrete is very thick in some areas, but I'm not sure how thick it is in the bay where I would put the lift.

 

The guy I had install my lift said it had to be at least 4 inches thick and xxxxxx psi cement (I can't remember the exact spec). The former owner of my house was a mechanic and built the garage with a lift in mind so I had less to worry about that way.
