i bought these used and when I first tore them down I dropped a valve on the floor.
The head broke off and I had a mini fireworks display.
I have to assume the previous had installed them.

I will have to check the level when I start on it. I had it installed so don't know if shims were used or not. I all so have a sloped floor for drainage.
I have used pole stands for years even when I worked in dealerships and for independent shops. Everyone used to make fun of me for using them but when you get 4000 pounds bouncing on the lift then it makes you think.
If I add an upper bar i will loose about a foot of height I can lift my vehicles so I really don't want to do that but I might have to.

I have 8 anchors, 4 on each post.
The lift is an 9000 lb lift asymmetrical lift. Champion brand.
I had it installed by the company I bought it from as I was working at the time and They were suppose to be there by 1 pm but didn't show up until 4 pm. I got home while they were finishing up.
They left me no instructions.
They did hammer in the anchors real good and I had no cause for alarm. I have checked them every 3 to four months and have had to tighten one or two every time.
The anchors they used looked like the standard 3/4 inch ones you would by at Lowe's etc.
So far I have been well satisfied with the lift as it allowed me to continue to work on my junk after my body said hold on.

i was on the web this afternoon and found some epoxy cement made for that problem, if that is my problem.
I don't have any tippy situations yet but won't rule it out in the future. I made sure the concrete was 3 feet thick where the post are mounted and they gradually thin out to 6 inches at the outer edge of the floor.
I will know more in the morning when I can lower the lift and see what is going on.

I am leaning to the idea that the anchor's are pulling out right now.
I will go out in the morning and tighten up the nut while marking the anchor and if the anchor is loose I will have to find a way to stabilize it or replace it.
It would be both the anchors on that side.
The concrete is not cracked and I can find no damage to it.
I did have some fluid that was leaking and it could have went between the concrete and anchor but I have never heard of that being a problem before.
I live in Oklahoma and we do have freeze conditions every winter.
That is why I pored a 3x3x3 foot area under the posts.
I don't think installing new anchors would be that easy and am just not sure how to fix the problem.
I am limited on where I can move the lift and unless I raise the roof in another part of the shop 10 feet I still would have to jackhammer out the floor and pore another base for the post's.

Charles machine in Arlington is an FE expert. He did my 428 and a bunch of others. Expert work and can do anything but it takes a while as he is a one man shop. would be about a 9 hour drive from you are but worth it.
He only takes cash or check, no cards so be warned

I guess i didn't have enough coffee when I posted an answer to you question but it is Autocrafters that have the headers for sale if you are still looking.
Greg
