So I have a 4-post "long & tall" lift that's served me well. Goes high enough to park a big SUV underneath.
I'd like to get a stablemate for it. As much as a want the utility of a 2-post, I'm thinking that another 4-post, with rolling jacks, can do most of the same things, and still be used primarily for storage. Lifts would be side-by-side in a garage with an 18-ft door.
Going this route would keep from having the "inner" post on a 2-post from being next to the adjacent car-door area, plus save me the hassle of tearing up 4-5"-thick concrete to set adequate footers for a 2-post.
Thoughts on rolling bridge jacks?

 

Before you rule out a two post my 9000 lb Rotary SP0A9 requires a minimum of 4-1/4” floor thickness and an optimum floor thickness of 5-1/2” to 6”. Minimum concrete strength is 3000 psi which most mixes make.

 

I got a 4 post Direct Lift installed in my home garage last year. I tried to use just the rolling tray with bottle jacks, doesn't cut it. I purchased a rolled bridge jack this year. My lift is mostly for parking and light maintenance, but even so the bridge jack is still money well spent.

 

Thanks guys. Mr. Nick, did you do the 3500-lb bridge jack?

Wow that's the best price I have seen on the roller jack. I purchased the 4 post 9000 lb. Directlift last month and it's one of the best investments I ever made. I'm very pleased with the quality. The Roller Jack is on my radar to purchase next!

 

Yes that is the bridge jack I purchased, same price too from a semi-local vendor. He even delivered it to my home on his way to another job.
