anchoring 2 post lift, How did you do it? Options

[Calwaterbear]

Ok time to set-up my new/used 2 post lift. I poured a 14'X 25' pad, let it cure for 3 weeks.

So I will drill into the concrete and use 3/4 X 10'' wedge anchors. they will be 8" deep.

obviously the holes need to be drilled in exactly the right places, not only for each post, but also, the 2 posts have to be set at the exact width (dictated by the bar across the top, between the 2 posts).

so do i set up the posts, bolt on the top, then drill down through the feet?

Or use a template, put in the anchors, then drop the posts onto the anchors?

Bit of an issue is i am working alone, and even with a bobcat 763, i have not figured out a way to get the posts vertical yet, i plan on calling in my propane guy, who has a real live Ferrari crane on his service truck to lift em upright and position them.

Tech guys at Greg Smith say to drill the holes a couple of inched deeper than you will be anchoring at - so if you screw up, instead of having to cut off the anchor - you just drive it down in the slab. That seems like a good idea, but what if, while lowering the post, you miss and hit the top of the anchors, that would probably drive them down into the slab - No?

I'm probably overthinking this, but I'm hoping to draw from the experience of others who have gone before me on this venture!

I put it in place and got it squared away, rented a Hilti from Home Debit, drilled it in place, put the washer and nut on the redheads (anchor bolt) hammered them in and then torqued them down.

Hardest part was standing the posts up, I have an overhead crane. Once standing I walked them over to the spot. The posts on my lift were actually very stable even unbolted.
If your pad isn't perfectly level take a large diameter washers cut one side out so you can slide it under the base at the bolts where needed, that's how the pros do it.
Electrics I hooked up temporary with BX same day, later I did it proper with conduit, Kellems grip, etc.
It was an easy job and I installed my Aamco 7K lift all by myself in a day.

It's been several years, I can't remember if I walked the post over a bit to clean it out or not. I don't think I did. Likely I just popped it up a bit and blew it out with air.
Once you drive the bolts in there's absolutely no way to move the post without some kind of lift. Frankly I wouldn't even try, too dangerous.

Thanks Mark - Thats what you do! I know the standing up is the big issue, but now i know to do that first, then drill and pound in the anchors. I already have a milwalkee hammer drill - my whole house is iCF - so I drilled a whole bunch of concrete during the construction. i'm thinking after drilling the concrete I can clean out the holes using a combination of compressed air and the shop vac working together.
The using cut washers as shims - absolutely brilliant, i will have a supply on hand to make the posts perfectly vertical!

I am trenching the route for the power. I will pull both 230 and 110 to the lift, so i can power the lift, plus plug in any lights, tools etc to work on the car I need. My lift is outdoors - because where I live 330 days of sun a year, and temps rarely ever drop below about 50 degrees.
