I bought a Atlas 8000 for nine foot ceilings this summer. I have 10' 4" ceiling.
I had it delivered to my brother's shop and used their forklift. Then we set it into my truck and I used my engine hoist to unload at my shop. It was easy to pick up the post with the engine lift and set them in place. I did the unloading and install by myself.
One thing I learned, a 5 1/2" wedge bolt with not work if the expanding ring is below the 4" slab. Messed up four and bought all new wedge bolts only to find out that I was installing them to deep for the expanding ring to work. I've installed thousands (I mean thousands) of anchor bolt in my career. Learn something new all the time.
I epoxy the four in with all thread rod.
Works great with a Cobra.
I should have bought a two post lift ten years ago!
I'm going to tray my ceiling this winter so I can lift truck the max lifting height.
Coach bought an Atlas 12' model in 2010 and it works great.
Jack just bought 12' unit and tray'ed his shop ceiling with no trouble.
Erik bought a 9' Atlas for the garage last spring. He is always building something. Right now it's a GTM
If you are going to change
oil or work on your car at home you need a lift. I think we all paid less the $2000 for our lifts.
