I posted this on the Tool forum too.

I just (finally) got concrete poured in my shop. Now I am wanting a car lift to put in it.
I am looking at the two post lifts. Does anyone have one of these? If you do I have a few questions before i go out and buy one.

Any input on these would be appreciated!!

Just a question....How thick is the concrete where you are going to put the lift?

If it is only say 4-6" thick, I don't think I would get a two post unless I cut out and repoured a thicker area where the post will mount.

I like the thoughts of a 4 post in the stability of it on 'thin' concrete.

Just my thoughts and not the opinion of others.

Yes, It is 4-6" thick. The only problem I have with the four post is you can't get the wheels off of the car like you can with the two post unit.

the 2 post my buddy has in his shop already has about a 2ft x 2ft maybe 3/8 thick foot on the bottom of the posts(came like that from the factory) he also has 2 4 posts in his shop. both have there ups and downs, the biggest down on the 2 post is the legs you swing under the car to lift it sometimes get in your way on undercar work.
we mainly use the 2 post for brake and suspension work.

I have a two post lift in my shop and I love it. My pad is thicker, but 4-6 inches of fiber reinforced concrete is all you need. 3000psi is a lot of load capacity multiplied 4 times or more. I have a friend with one as well and his pad is about 5 inches thick. Most two post lifts have a mount pad of 2 feet or better span. Spreading the load is not a problem. The four post takes up alot of valuable room in the shop. There may be a few minor areas you can't get to depending on were the jacking arms are on the car, but the whole underside other than that is WIDE-OPEN! Great for exhaust work, transmission work, suspension work, rear end,...I just have had no troubles. I have also had a 7500 pound work truck on it with nor problems.

Thanks Mike. Who did you buy your lift from?

Thanks for the input on the lifts.

I am going with the two post lift.

I have two cars that are 4 linked. I am tired of the jacking tricks to get the tires out from under the car. The two post lift makes more sense to me and the things I work on the most.

There's a hydraulic jack that can go between the ramps of the 4 post unit to lift just the wheels if thats what you need. You just use that, don't need any jacking tricks and in my experience everything is much more accessible with the 4 post unit.

Wouldn't this extra jack be just like jacking the wheels on the ground? If so, what good does the lift do you?

I may be a little late on this, but my uncles two post lift just ripped out of his 5 inch thick concrete slab at his shop. Ripped out I say, took the whole damn floor with it, and the vehicle.

Ouff dah.

BTW I found out that they recommend something like 12 inches of concrete for the lift

I just looked on Rotary Lift's website, and they recommend between 4.25 and 5" thickness depending on model, but it looks like all models meant for light duty (normal cars and light trucks) would only need a 4.25" thick slab with 3.25" of anchor engagement.

With thinner pads, make sure the car's center of gravity is right between the posts. Don't put the car on too far forward.

Good Luck!

Have a four post lift and will never go any other way. Dont have to worry about balance, centered alignment, nothing. You will never have more access to the underside of your car than with a four post. If you plan on doing adjustments to your rear suspension etc., dont even think about a two post. BTW, for removing tires, changing brakes etc., I have two tall tripod stands that I use to install under the frame rails and then let the lift down as far as needed. For me it's a perfect setup. Good luck

I have two backhalfed cars. the four post lift will never be able to lift the car high enough to remove the rear end. I have decided to go with the two post lift. finally. I tested both and the Two post makes more sense to me and how I would use it in the long run.
