That is why I upgraded the hoses and fittings to quality Parker USA rated at 5000 psi min, about double the Max Jax system pressure.
In speaking with their engineering department I found that there is a 5:1 safety margin for the anchors. I ordered an extra set so that I can have two mounting locations for larger and smaller cars. I have 5 cars that I do all the repairs and maintenance on so it gets used frequently.
I measured the deflection at the top of the columns and found only 1/8" per side with my 4500 pound Buick on it.

Sorry to have caused such a stir with my first post here but I was really looking for safe lift points (from the vehicle's perspective) for my Model A.

Thanks for your input as an engineer ! Data is important in making decisions and that's what you've contributed as to this lift/jack. Now we who are contemplating making a costly equipment purchase have some things to compare with diff equipment :) !

Re: MaxJax 2 post car lift

I think we can all agree that nothing is 100% safe as all equipment is built by humans and we are far from perfect. If my garage would have had a tall enough ceiling and more floor space I would have likely went with a 4 post lift or a commercial 2 post.

I lost a high school buddy over 20 years ago who was working under a car supported with cement blocks. It is not something I take lightly.

Here's my Wildcat on the Max Jax with the bridges I designed and built to reach the narrow X-frame. I am sure the makers of Max Jax would not condone this. The car was supported like this for ~4 months.
I do have several tall support stands for safety purposes so the real danger is during the raise and lower cycles.

Re: MaxJax 2 post car lift

From what I'm seeing here,,,, looks like the MaxJack is good for raising the wheels up off the floor to remove tires, do brake work etc. Use jack stands for extra safety.

But not safe to actually get under the car. When I get to the point where I can get a lift, it will be a four post drive-on for me no question about it......

Re: MaxJax 2 post car lift

Looks like Max Jax will fit the identified height limitation.

As every one said, including original the poster, block it. I had a friend damage half his face for life over not blocking. Something I am familiar for a lifted toy is a wing jack for a high wing airplane. Simple and you can make it yourself. I just sold a set.

With more height I would opt for the 4 point lift and you have cake and eat it too. I see one in my future as I am getting older. :-)
