6x6 as anchor post?

[USAFpj]

Our shop slab is going to be poured this Wednesday, and short of the wife able to find a local place that sells anchor pots, I'm unsure of what I may use as a 'bombproof' anchor.

This anchor will occasionally (twice per year) be used for pulling rolling dead vehicles, up onto the 4 post lift. The poles are 6x6's, but I'm not sure if I want to laterally stress a structural beam made for vertical stress.

Anchor pots are the answer, but I'm just not in the area to provide them with one when they pour the slab. I would think a 10K lb rated anchor strap placed about 6in above the slab would do the trick?

Make one out of angle iron and bolt it to the floor. A simple A-Frame type structure, built from 3 x 3 x 1/4 wall angle, will be strong enough for a 3 or 4k dead pull.

2" receiver tube (part of Class 3 drawbar hitch), canted slightly backwards, I'd go with 1/2" to 3/4" top to bottom to resist pullout of the strap. I would fill the end with Styrofoam that you can chip or pullout later, to avoid it being filled with concrete, as it inevitably will.

The other possibility is to source a heavy piece of rebar, say 3/4" minimum, and find your local fab shop, have them heat part of it red hot and bend to a sort of an "omega" shape with longer tails. Consider than heavy concrete culverts, etc, have a piece of exposed rebar used as a "crane hook". The disadvantage is it will always be sticking up.

If you're not home, order one and have it shipped to the house. Have the concrete guy place it when they do the floor or this one can be put in after the concrete is poured.

No windows? I've run a strap out a window and looped around a tree behind the garage to pull cars before.

You don't need a special pull-pot to pull from. You could stick a big eye-bolt, or even a bent loop of rebar in the concrete before the pour. Just do it against the wall so you don't trip over it.

For pulling onto my 4-post lift I just wrap a strap around the lift crossbar and pull from that.

A simple solution is to sink a vertical pipe of suitable diameter flush with the floor when pouring the slab. I suggest this pipe to be 3" in dia. x 24" deep. Once installed, you simply drop in another heavy walled pipe to use as an anchor for you come-along when dragging in dead vehicles. When not in use you may cap the hole to keep out dirt and small items from falling into the opening, and no worry about tripping over anything more permanent. I'd use a heavy tube or pipe with an eye screwed in place, stored where it can be found when needed again.

The poles are 6x6's, but I'm not sure if I want to laterally stress a structural beam made for vertical stress.

If you consider the wind load that hits the walls of the building you may see that the 6x is also good for shear loads. If you wrap a strap around the 6x low to the floor you will have no problems. I've done it many times.

no neat sig line

Why not just put your straps on the front two posts of the four post lift? Spreading the load across the two will put a smaller load through all those anchor bolts going in to the floor, which should be no problem. (Unless you aren't planning on bolting your lift.)

If all else fails - just have the wife come out and push! (Mine complains when I ask her to do these things, but usually complies when I explain the alternative is to buy more tools...)

I used a short piece of I beam embedded in the concrete so that one flat surface is level with the top of the concrete. I haven't had to use it yet, but when I do I will just weld a loop of chain to the top and attach a come a long. In the mean time, it is completely unobtrusive and does not fill with debris.

When my brother moved close to town and built his garage. He had a junky 1/2" chain with a good size hook on it. He slurried that chain into the concrete and left only the eye of the hook showing. He used to chain/padlock his motorcycle to the hook.
Along the same lines a similar chain/hook slurried in to the concrete with a anchor pot(?) around it would be then flush with the floor, yet available if ever needed.
(I didn't GOOGLE anchor pot so I maybe wrong?)

I saw one that was in at least weekly use in a commercial garage.
It was in a pole barn with the post spaced 8 feet.
Cabinets on the inside wall facing the door.
In the toe kick of the cabinets was a heavy3 foot chain with a slip hook.
It went under the cabinets, through the wall and outside, then through a 4x6 that bridged two posts.
A heavy bolt through the last link.
They just used a "come-a long" to pull whatever in.
I watch them pull in a loaded 1 ton flat bed truck with no problems.
