I just have seen a picture yesterday, at a high end car dealership where a I think it was a BMW fell off a two post and fell on another car.

You just have to make sure the car is on it right, can't be in a hurry.

There is not a thing wrong with two post lifts, except they stay where you put them. If you get it wrong they stay there or you jack hammer them up.

With the four poster you can move it around, out of the way.

I have seen one car fall off a two post lift, and I have seen many pictures of cars that have fallen off lifts, all two posters. Just make sure you are putting it in the right place, and that the car is on it right.

My 9,000 lb. Metro 2 post is bolted to my 4" slab. Minimum requirement from the manufacturer. This was put in as an after-thought but I have had no issues with it and all of the bolts are tight with no floor cracks after 5 years of use. An Astro van body has been sitting on the hoist since last November with no issues.
IF I was doing this from scratch with a new pour I would dig out two 18 x 18 x 6" deep pads and call it good.

post support.

A two post with a substantial top connecting structure will not put much stress to tip the posts over. before I lift my dually F 350 dump again I will build a heavy inverted U bracing and bolt it to the top of the posts. My two post has the connecating cables and hoses recessed in the floor witn a metal cover.

Open top on my Metro. Cables run in a tray across the floor. Like I said, no issues with no special prep to install the lift.
Now, lifting a big rig like your F350, I would probably not do without some re-work of the pad area's. Lifting less then 4000#'s doesn't seem to be a problem with a plain slab. It just depends on what you plan to do with it.

The cars that I have seen fall from a two post was not the fault of the lift it was the guy who put them on the lift. He didn't get it right, or they didn't as like I said I saw one in person and several in pictures, one not too long ago where I think it was a Audi that fell on a BMW, I would bet that guy got promoted right out of the shop.

I like the two post as you don't have as much in your way when working, but I like just driving on an hit the up lever. I also can lift one and park another under it.
