I just bought a used Asymmetric Rotary brand model SPOA88 7000 lb. lift and i am going to try to install it myself it will go in the corner of my 40'x60' metal bldg. i know this is not a ideal place to put it.So i am going to have to drive in the front 16' wide door and try to square the vehicle before it goes on the lift so i probally need to put it as far back in the corner as i can.How close to the back wall of my shop does the lift need to be located so i will have enough room to work on the front of the vehicle when need be?

I'd allow at least 10 feet and then you should have enough room to put a bench along the wall in front of it.
but that will depend on the layout of your shop and what you normally work on in there.
I'd also leave it out about 3' from the side wall to allow you to walk around it easily.
nothing worse then being crowded when you try to work on something.
hope this helps

That's a nice heavy duty lift...be careful of installing those verticals by yourself or without the right equipment.
The verticals on my previous 7,000# FORWARD commercial two post asymetrical lift each weighed 1,000# and were 12 ft tall. I chose the cowardly way and had a professional install it...best $300 (for 4 hours) I ever spent.
Give yourself as much room as you can spare so you can make full use of that asymetrical lift feature. If it were me, I'd center it in the shop rather than trying to put it off to one side.
I used mine for a variety of vehicles once my friends found out I had a lift. I finally told them that my insurance wouldn't allow others use it just so I could use it myself.

I agree with hotwheels55 about having a pro install the hoist.
you dont want it to fail while you or your buddys are under it.
Also of inportance is the grade and quality of the concrete floor that is holding this thing up.An asymetrical hoist puts a lot more strain on the floor than a symetrical design does because the weight of the vehicle isn't centered over the posts,but biased to the side with the longer support arms.the concrete should be a high psi strength rating and at least 6" thick to support the load.
