lift concrete specs?

[volaredon]

I have a 6 year old garage (30X36) that I planned on eventually putting a 2 post above ground into since I was in the planning/permit stage.
I have between 5 and 6" of concrete throughout with extensive rebar throughout and an 18X24 footer all the way around.
I finally got my lift last week and am anxious to pt it up. Will this concrete base be sufficient? the lift capacity is 9K though I don't see lifting much of anything that weighs half that.
also is that 9K just the max weight of the lifted vehicle, or is that inclusive of the weight of the lift itself? (the columns are like 900 lbs each maybe a bit more)

The lift manufacturer should have minimum concrete specs as well as lift specs. I would go with that.

Your concrete should be fine. 9000 lb is the max vehicle weight you should lift.

Concrete is fine IF the PSI is min of 3000 else the wedge anchors may pull. Most all concrete is a min of 3000. The lift will lift 9000 pounds not counting the weight of the lift.

Jump over to the flooring threads and you will find a lot of people who can give you some solid information

I have a 9000# 2-post lift and the manufacturer required at least 4 inches of 3500# reinforced concrete. I have 5 inches of 4000#, so it was good to go.
The instructions said to install the anchors, torque them to 100 lb. ft. If any anchor had an inch or more of threads showing, it was not sufficient. Then put a car on the lift, raise and lower it a few times, and torque the bolts again. If more than an inch of threads showed, again, it meant an anchor was putting through.

I put in a 9000lb lift but my floor varied between 3 & 5 in. To make it safe I cut out 4ft squares where the legs bolted down, dug them out and poured 12" thick pads. When I'm working under a car I don't want to worry about anchor bolts!

TO OP, I believe you have gotten some very solid information here from some of us who actually know what we are talking about since we are lift installers for 30 years.

ok I ain't disputing any of it at all that's why I am asking now before I put the lift up.... I wanna make sure that what I have is sufficient
