What Is This Lift Called?

Mine only cost me $450 back when I got it.
I was afraid of losing out in the time I hung up the phone and got there with the cash....
I had to take it down where I bought it and re put it up here.
In between buying it and putting it back up my son was working at a place that did powder coating and sandblasted and powder coated the entire thing. 318 blue columns and foot pads, hemi orange arms. That wasn't free but much reduced since he worked there and actually did the job. He did the powder coating as (I forgot which) Christmas present or for my birthday present or father's day that year.... So that part didn't cost "me" anything...
