Garage lift recommendations

[Bayern///M3]

Built a new house and shop in 2022/23 and installed a Atlas FM9SL https://www.atlasautoequipment.com/p...tionary/fm-9sl

Absolutely love it!

Reviving an old thread:

Has anyone used a quickjack (or another brand of this type) on a driveway with a slight incline? Quickjack says 2° max, I calculated mine at 2.45.

I know it's less than ideal, but unfortunately it's the only place where I can leave it sitting for a night or two...

Quickjack's US website says 3 degrees (see question #8)

My driveway is just under 2 degrees. The Quickjack is very stable. I'll probably never use regular jackstands again.

How are you calculating the grade? I don't think 2.5 should be an issue but you want to be confident in your measurement.

I would orient it so the hydraulic lines are pointed toward the downhill. So the QJ would be lifting against the grade and you won't experience a shift in CG toward the decline.

I was about to add that you do want to orient the QJ so that it arcs "uphill" so, as you said, the hoses point downhill.

I used an 8 foot level, and measured how much I lifted the lower end off the ground to get it level. With that measurement, I used arctan to calculate the degrees. So in my case, it was roughly 3 inches over 96 inches.

8 ft is a decent span which should cover most wheelbases.

If you wanted to double check you could either use a laser level and yardstick and measure the height delta at various points or get some clear tubing and a friend to done quick water level.

I've made mistakes before where small mistakes at small spans propagate at large mistakes at longer spans.

I know the length of the driveway and I know how much higher it is in the back. From there it's simple trigonometry, arctangent in a calculator and go.

I will probably add rubber mats underneath the qj, the driveway is kinda rough...

The rubber mats underneath the QJ is going to make adjustment position extremely difficult. You're better off just letting the bottom of the QJ get scratched up and touching it up with some spray paint once in a while to avoid rust.

When lowering the car on the QJ on the decline I would highly recommend getting into the habit of setting heavy tire chalks. One of my friends had a car roll down his driveway even with the e-brake set when taking it off jack stands. He ended up cutting a concrete square and setting a steel D-ring in the pavement then using chains with the tow eye as extra precaution.
