WOW thats fantastic! Great Idea......Let me know when your selling your house ;) I'll just bring my 2 post hoist with me and be set! Best of both worlds......
My shop is 2 stories !! If I had the head room, I wouldn't have built this hoist.
There's no drain, those are paint drips from another project. It wasn't designed to lift heavy vehicles, and I have the pressure relief set so that it can't lift anything more than 5000 lbs. Tripping into the pit wouldn't be anymore hazardous than tripping on the same hoist if it was just sitting on the ground. Besides, the plate is always on unless I'm lifting my car.
If I need to replace a transmission or do exhaust work, I made 4 stands that the vehicle's wheels can sit on. I then lower the hoist and replace the steel plate by sliding it over and into it's groove . All this was thought of in advance!!
Here's some old pictures I found when building my car. The first picture shows the stands, but the metal plate has not been replaced yet. The plastic bucket hanging from the ceiling is where the 1/2 ton hoist is to lift the steel plate.It rides on a rail with about 5 feet of travel. The bucket keeps the chain from hanging down and knocking the beer out of your hand.

There's a few discussions here on different types of car hoists, and this may be the answer for some of you. I had a few people ask me about it, so I figured I would post some pics.
This hoist IMHO, is the only way to go !! The only draw back is that you can't walk under the car.
When it's down, you're no tripping on it. With the plate left on, it's the best welding table because you can raise or lower your work to a comfortable height. It's also perfect for working on lawn tractors, snowmobiles etc.. Another bonus is taking heavy stuff out of the back of a truck. Just slide the load right onto the table and lower it to the floor
With the plate off, the outrigger arms come out to lift cars. It takes less than 30 seconds to remove the plate, and a 5 year old could do it.
I built the hoist a few years ago when these were selling for over 3 grand. Today I would just buy one.
My total cost including the concrete for the hole is about $1500.

This is a brilliant way to have a disappearing welding or workbench or small equipment hoist (sled, garden tractor or motorcycle). As a vehicle hoist, I suppose it has some merits for stuff like brakes & tires. Though it appears well built like everything else you have done, I feel its a little light for anything heavier than a small car. (I've seen numerous dump trailers with a similar ram set up fail under load). It's also not usable for dropping transmissions and stuff like doing exhausts due to the obstructing scissor assembly. Tripping through the pit would be another downfall....bad pun.
I don't mean to be negative as it is an awesome work table...just not sold on it as a car hoist is all....
How did you get away with having a floor drain? That's against code here

As I mentioned in another post (believe it was the one regarding your blast furnace/kiln/melting pot), I think it is fan friggin tastic.
I love it, great idea and execution. Also love the stands that allow retraction of the hoist/table to allow full access to the underside. This has to be the PERFECT hoist for virtually any large or small garage as it is completely out of the way when not in use.

Hemi, Thats why they invented Chainsaws......to cut hole into the second story!
I'm sure with your fab skills it would be a walk in the park to add a post hoist....
I rent my shop.....or i'd be doing what you did with the scissor lift

If I had to it all again, I wouldn't build a 2 floor shop !! Having said that, living where I do I had no choice. It was the only way to get the square footage of shop space and still keep the township happy. I have a full woodworking shop upstairs, so not being able to walk under my car is a small price I have to pay. I really wanted a 10 foot ceiling on the first floor, but the height of the building would have been legally too high. Thanks for the comments !!

Ok, now that changes everything!!
I didnt know you had the stands and could replace the plate so you could work under the car - hope you didn't
find my comment too negative...it is quite the piece of eqipment...wish I had one myself

My store bought unit is similar to Hemi43's. It is factory rated for 6000lbs. I have had a GMC 4dr 2500 Sierra 4x4 on it.
Which looks identical to Hemi43's.
Does anyone know what the factor of saftey is for car hoists? FOS for overhead lifting is supposed to be 5:1. There's no way these scissor tables will carry 30,000lbs, so the FOS must be closer to 1.5
I recently bought a large high lift table for a customer to get garbage bins up to a second level. I'll have to look up the capacity on it...it was built much heavier than your standard elevated work platform

What they will hold, and what they will lift is two totally different things !! I tried to lift my truck which weighs about 5600, and I was just able to get the tires off of the ground about 2 inches. Mind you, I have the pressure dialed down to prevent lifting something too heavy. The weak link is the pivot pin, and its made from annealed 4140 steel which has a shear strength of around 70000 PSI. That means that it takes about 50000 lbs to shear that pin. The hoist has a mechanical advantage of about 2:1 on the pin, which means a 25000 lb load will shear the pin. There are 2 pivot pins, so that brings us back to 50000 lbs !! Do you see where I'm going with this ??

We used 2 in our tire shop in Exeter Ont. (16 years) we used the hoist to lift the front up and a floor jack to lift rear off ground (trucks only)
Just buy a standard scissor lift ( They retail for around $2000) and modify your floor. There's really nothing special and quite easy to do. The reason I built my own hoist, about 8 years ago, is because at the time these things were selling for over 3K. Today I would just buy one. If you do all the work yourself the floor modification shouldn't cost anymore than $400 and a weekend of work.

That hoist wont work. It's only rated for 36". You need one rated for 52" or 60". Right off the bat you will lose 8" of lifting height because of the hoist is recessed into the floor.
Very true there! Even if it was not installed into a hole in the floor, 36" would still mean bending over to do any brake work or what not. Have been looking at some of them online. Almost half the price in the states.
