yeah, i would trust a lift supported by just a couple lag bolts. NOT! better pray it doesnt pull those anchors. you would never know if they are inching there way out, Pulling bolts out and putting them back in all the time would probably take a toll sooner or later
I have a super low ceiling (at the moment) which is maybe 7-8' with a big carrying beam across the middle!:bash: Anyway, I found a deal on a nearly new drive on, 4 post lift from a guy that was relocating across the country, and didn't want to ship it. I rented a big trailer, and drove about 3 hours to pick it up, but it was one of the best things I have ever bought. Right now, I can only get the car up with maybe 3-4' of clearance, but it still makes doing any type of undercarriage work, so much easier! I have started re-trussing the roof so that I can raise the ceiling this winter. Since I have a decent sized ATTIC ABOVE THE GARAGE, I will end up with around a 14' ceiling above the bay where the lift is, then leave the other half attic for storage. What I like about a 4 post, is that you don't need to lag it down to the floor at all, because it is self-supporting on it's own plate feet. My lift also came with some really cool dollies, so it can raise itself up, and easily roll out of the bay, or wherever I want it.
If you don't have the ability to raise the ceiling then the one in this thread might be a great option for you.:beer:
