4 post lift with warped feet

[70-K5]

Brought home a brand new Atlas Pro-9,000 lift. As expected and reported by others, the instructions stink.

The reason I went with a 4 post is I wanted the rock solid stability and assurance of a 4 post. I did go for a rolling jack so it will be a useful tool.

My concrete is about 3 years old and pretty flat. After completing the installation it said to shim the columns do account for uneven concrete. Well, turns out the feet are warped, guessing from the welding process. Perfect...

I do not want to bolt it down and I've heard they can walk a little if not bolted, so if I shim today it might not be right tomorrow as the legs shift on the shims.

My neighbor suggested a high strength non shrinking grout, but that doesn't help when I want to move it to the next bay.

I've thought about adding new plates to the bottom that are flat. Then welding nuts into the holes in the plates then using screws to level the columns on the plates. I don't know if anybody has any other creative solutions.

So far manufacturer has not been help, I'm guessing il get the, shim and bolt it down answer...

Our rack installers bolt (really stud/nut)everything, shims are required. Normally they just stack a bunch of 2" diameter washers.


Want to move it? Unbolt, drop the verticals onto a batch of tires. Grind the studs remaining off with an angle grinder.
