Was the floor reinforced in any way to support a hoist even if it is portable?
My 2 cent thought.
I don't know if I made a mistake with mine or not but I built my work bay that was to have the hoist with no extra reinforcing.
My thinking went this way-
If I had a Duramax 3/4 ton diesel, I'd park it in that bay. The footprint of the front tire on that truck is likely about 100 square inches per tire. It likely weighs maybe 5500 pounds (from what I could find), so 2750 on each 100 square inch print.
My hoist weighs 1700 pounds. Each of the 4 post pads is 144 square inches. Let's say the heavier end of the hoist weighs 1000 pounds, so 500 pounds per post. Say I park my big block Pontiac on the heavy end of the hoist. The front axle on it likely weighs 3000 lbs at the absolute worst, so 1500 pounds on each front tire. Add the weight of the hoist post (500 pounds) and I have 2000 pounds on 144 square inches with my Pontiac on the hoist post vs 2750 pounds if I park my Duramax on the concrete floor.
I don't really put anything heavier than a Pontiac on the hoist and even if I did I still have 750 pounds per tire to spare before I'm up to the weight of a Duramax.
And maybe I'm all wet behind the ears but that is how I rationalized it when planning.

Re a floor coating, my buddy built a beautiful shop about 15 years ago, and paid to have an epoxy coating with the speckles in it on the floor. It is EXCELLENT. Very durable, not slippery.
The only problem is if he drops a screw it's very hard to find, so he uses a magnet to locate it.
Kim, are you planning to put in air lines along the walls? I wish I had. Now with cordless tools I don't use the air hoses near as much but still there I times I do and those hoses all over the floor are annoying.

My concrete guy applied a hardener to both my attached garage and shop floors. It has to be applied within two days of pouring the floor as it cures. It results in a more robust surface with less dust. Ive never had an issue with the floors being slippery. Hardener is reasonably priced and easily applied with a sprayer. A sealer can be applied after 4 weeks but I didnt seal mine.
I have a four post hoist due to the flexibility and ease of moving it around and not having to anchor it to the floor. That thing is hands down the best tool I have ever bought. My shop floor is structural, 6 inches thick with a widened edge so I am confident that the hoist can be located anywhere in there without concern. I moved it a couple of times until it now sits in a more or less permanent spot. It looks as though your building is on a grade beam and footing so your floor will be a floating pad. I am not an engineer but a 4 inch thick pad with a higher than normal mpa concrete and adequate steel re-enforcement should handle a four poster. If you decide on a two post hoist it has to be fastened to the floor and in that case I would thicken the floor at the posts. The rub with that is either you thicken the floor in a number of locations to facilitate moving it around or think it through and choose one location where it will stay put.

Thanks Mike. The price of delivered cement was such a stupid price in 2023, plus having it poured and finished was crazy expensive. I never had the comfort of stopping to think of a stronger pour. I actually have a rough idea of where I want the lift to sit, so could be forced to make a final call. Sounds like 4-post is the answer though
