I've installed a four post lift recently. It also came with a set of casters so I can move it around. However, in my single car garage, I don't anticipate moving it. So I'm ready to anchor it in place.

The base plate is 1/4" steel with four 1" holes.

I can't find Red Head anchors that are 1". They seem to max out at 3/4", so I found this set that I think it more than adequate for the 4000# car I have on the lift (it's rated at 7000#, hobby-level quality).

This should do the trick, right?

Home Depot Red Head

1" anchors are readily available. It wouldn't panic me to use 3/4" but why if you are not in an emergency.https://www.mcmaster.com/concrete-anchors/steel-stud-anchors-for-concrete/diameter~1inches/

Try a fastener shop for larger fasteners. How thick is the slab? If the hole is one once I’d put as much fastener as I could in it.

If your lift is on casters, then it would seem fastening it to the garage floor isn't a structural requirement. I would think four 3/4 Red Heads on each corner would be fine. I'd look at the lift manufacturer's instructions or give them a call just to be sure though.

Tension strength of one 3/4" Red Head, 3 1/4" depth in 4,000psi concrete is over 10,000 pounds.

Yeah, better Google skills found 7/8" and 1".

I've found a solid set of 7/8" x 6" Simpson Strong ties.

The concrete slab is 6".

Yeah, it's not a requirement. Perhaps I've still got to do some tweaking of the post and cables. When I have the 59 Chevy at the top, I get a little shifting of the post to where the base plate picks up just a bit (1/8" to 1/4") off the ground.

Before drilling and bolting down, I'm gonna review the installation manual to double check my alignment etc.

Those 3/4” anchors are fine for that application.

I installed my Rotary 10k with these. It’s what the seller highly recommended.

I don't know if there's a reason to use an expansion anchor as opposed to a drive in anchor for a lift application, but I rarely use expansion anchors in my line of work.

Even the 1/2" anchors I have on the truck are rated at 7,500 pounds of pull, and 11,000 pounds of sheer. Drill a hole, drive them in. Done. And if you move the lift in the future the entire anchor unscrews and simply leaves holes in your floor.

These are what we used for our 12K Rotary lift. We also use them for Jib crane installations.

If you’re putting 4 anchors on each corner, 1/2” would still probably be way overkill, but set the anchors as deep as you can. Residential concrete quality can vary. You don’t want the anchor to flake off the concrete when you tighten the bolts.

I would also recommend grout under the plates after leveling.

As a Millwright at GM auto plants I installed thousands of concrete
anchors over the years, I would recommend these:

The ones marked average would be more then enough for you. Easy to install.

TIP: Drill all the way through the concrete to install. Makes it easy get rid of to when you want to.

Why not just contact the company that manufactures the lift and ask them for direction?

I bought a used unit and the manufacturer isn't around anymore. My unit appears to be identical to several mid-grade units available today. I've looked into them as well.

It comes with 1" holes so I'm guessing I ought to go for something as close to 1" as possible.

Probably best advice.

They definitely make that size in the Trubolt. I suspect a local bolt shop/distributor will carry these and if not, just order some from someone.

For something that important and non-urgent, I'd take the time to use whatever the max holding option would be. Also the washer they supply will fit better on the 1" hole. Using a smaller one could make that the weak link more than the bolt. And for sure don't substitute a lesser grade washer in there.

BTW - I've used their products on a couple applications and they rock. Well, not really, they're super stable.....

I have owned and used my 4 post hydraulic lift for many, many years. It is set up where one can use casters on the four posts to move the lift about, but I have no need to do that.The base plates have holes for anchors, IF, one chooses to do that. I have never seen the need, and just have the posts sit flat on the concrete floor. Mine has never moved, once it was leveled and the cables were adjusted correctly. Just a thought!

I'd bet if you called BendPac's customer service they'd be able to provide you with some worth while feedback.

I've used those to anchor high voltage circuit breakers to the slab . They work great .

That would be my plan as well. I gave you a link above to 1" ones. And I would expect a tiny amount of effort will find a number of sources. So I'm confused on why that isn't what you would do?
