I had a lift installed a few weeks ago and I think it needs bolted down due to the slope of my garage. Does anyone know a good lift installer that I could contact to do the job. I want it done professionally. Thanks!

What kind of lift?

I did my own installation, it's really just drill holes (SDS drill), clean them out thoroughly, hammer in the anchors, and torque them down to spec. Nothing too challenging.

And if you screw up, make sure you drill through the slab when you're first drilling so you can hammer down the old anchors and put in epoxy ones instead.

It’s an Atlas. My floor slopes 3.5 inches front to back and one rear column is .75 inches lower than the other. So, it needs some serious shimming.

As long as the ladder locks are level why does it matter? The ladders are adjustable are they not?

Onami

Look at how close the column is to the drywall at the bottom vs the top. It’s very unnerving to see the lift slanted to one side.

Yes, 2 inches of adjustment. I have 3.5 inches of slope. I’m more concerned with the side to side slope.

Greg981

Oh, you're saying one post is 3/4" out of level? Yea you need to shim that. They each should be plumb.

Onami

Yes, that is correct.

My posts all have shims under. My floor slopes a lot as well. Took some time to get them all right.

I’m having some full size 1/4 inch plates laser cut next week for the low side rear post. That should at least get the two rear posts on the same plane and then they can be shimmed plum.

I had to shim my garage floor as well when i installed my two post lift , the issue i had was one of the legs for the lift was now higher than the other
and my race car is very low so it is always a struggle to slide one of the legs under the car.

If i remember , the instructions allow for a .250 inch difference in side to side measurements.

Thanks Phil.

I had my guys at work make up some full size steel plates for me to play with this weekend. I had a drawing made up of the base plate and a DXF file created to send to the laser cutter to make some 1/4 and 1/8 shim plates.

Nice solve. On my lift, I had a similar issue but I used an old nylon cutting board since my low spot often has water in the area and I did not want the footing of the lift to rust. 7 years later the cutting board is doing fine, LOL.

Onami

I read about a couple of guys using nylon cutting boards and they worked well. The plates are $11.50 each for 1/4 inch thick plate. I’ll hit them with lots of Black Tremclad before installing. Found a company to do the bolt down in early October. It will be interesting to see what they say about the initial installation given the slope.

Spay them with a lite coat of Krown rustproofing after you paint, you can get aerosol cans at any Krown dealer. Or even some anti-seize compound.

Have a look at my installation ... my garage is 24 x 32 and i had a slope as well where i chose to install my two post lift.Anyhow , i had to cut out two 5x5 slabs in the cement which allowed
me to make both sides fairly even as i used a laser level when i installed the new rebar and high density concrete , but i still had to shim one of the posts as you can see.
I used a 5/16 metal plate and the hard plastic "U" shaped shims that came with my lift to make everything level side to side and fore - aft .

Been six years already and everything is still level !
