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
