Four Post Auto Lift

[767Jockey]

I was thinking about a one post lift. With a four post, while stable and cheaper, even when the cars are out of the garage you have this big thing taking up half your garage. With a one post, you install it so the post is against an outside wall, and with no cars on the lift and the lift in the full up or full down position, your garage is essentially empty as normal, enabling you to work on a car in the middle of the garage if you wish with plenty of room all around. It also seems like it would be much easier to get in and out of the car parked below with a one post lift, and much easier to park under it as well, as you don't have to thread the bottom car through two posts. With a one post lift, you just park underneath with no real tight quarters laterally to have to navigate.

Have any of you guys used one of these one post lifts yet? They look pretty stable with the heavy duty splayed arms and all. Any experiences you've had with a one post lift, certain brands, where to buy and costs, etc would be appreciated. Thanks.

No experience but I'd imagine you'd really have to beef up the slab for this. All the weight of your car in a couple of square feet. A typical contractor grade won't do as even the double post needs 4+ inch slab. The 4 posts aren't an issue as I though they might be but I'm not working on a car underneath the lift but rather on the lift. If you're looking at single post with the large base then the base would be MUCH more of a nuisance than the the addition 3 posts. They look like twice the price.

The punch through on the concrete would not concern me. It's the bending moment load that is trying to pull the anchor bolts out of the floor that I would worry about.

If I was going with this type of lift, I would also anchor it to the wall or ceiling just to be safe.

The other negative of this design is that the cross bar blocks off some of the access to the underside of the car.
