Installing a 2 Post 10,000lb Vehicle Lift! - Check concrete FIRST!!

[@deanandrejevic1946]

I used to install Bendpak lifts in the UK and seeing lifts falling over because concrete isn't deep enough is scary as hell. We used to fail the floor on anything less than 6". Glad you went with the deeper concrete. I don't know if you'll see this but make sure you check the torque on the bolts again every few days for the first few weeks, the bolts will stretch as they settle.

[@elrobo3568]

As a first responder I had two fatal accidents where the person installed a two post lift in old concrete that was not thick enough. when I had my pad done I had the concrete contractor do the pad 8 inches thick with the 24 inches where the lift was going to be 12 inches. I had 7500 psi concrete used. There was also a lot of rebar put in with boxes around the post attach points. It cost me an additional $300, I love overkill as opposed to getting killed. It was worth the extra money for my peace of mind. My lift is a 10,000 lb. lift.

[@finkyfamboni4333]

an extra 300? ONLY 300? WHY WOULD SOMEONE NOT DO THAT? THE WHOLE INSTALLATION HAS TO BE OVER 10K AN EXTRA 300 TO ENSURE YOU DONT FUCKING DIE IS NOTHING? HOW DO PEOPLE CHEAP OUT ON THE CHEAPEST AND MOST IMPORTANT THINGS???????

[@WilC379]

@@finkyfamboni4333 It's a lot cheaper when you're first building your house/shop to make these changes. After the house/shop is built it would probably cost around $2500 to have the pad tore out and the new pad poured. Still, $2500 is cheaper than losing a limb, becoming paralyzed, or losing your life.

[@modquad18]

I don’t understand why the column bases have such a small footprint. I would never get under one of those things regardless of concrete thickness. You’re relying on those anchors which could pull through or fail regardless. They should use 4 posts or have a large enough base under the 2 posts so that the thing could stand on its own with a vehicle on board.

[@RavingDavith]

Civil Eng. here, I about had a heart attack when you said it was ok for 4inch thick concrete, glad you didnt go with that. also you might want to give the concrete coating of Epoxy, PU or MMA flooring to stop oil, degreasers and other toxic crap from corroding your concrete, I have actually seen that stuff get under the lifts, break down the concrete and cause the lifts to destabilise , also might be worth putting some Silicon around the lifts base.

Here in Europe the requirement for these types of installations is typically 20cm (just under 8 inches) of concrete so it's really good that you got a thicker slab. Safety is important, so sometimes you've just have to bite the bullet and get it done properly.

[@doug900S]

A lot depends on what the PSI of the concrete is. My floor was poured 4" but extra heavy concrete (higher PSI). My contractor knew I would istall a lift someday so he made sure it was poured correctly. Also has double rebar and steel screen. Now, if the lift will finally get here...

[@dennyoconnor8680]

Being a lazy critter with experience setting bottom bolts on towers up to 200' tall, the one thing I would have done differently is to make a one piece plywood template of the footprint of the two (pillars perfectly spaced and aligned of course) and used that as a jig to suspend J-bolts in the wet concrete - voila, done. Not criticizing - just suggesting for anyone watching the video and thinking of a new floor under their new lift.. Also, an existing floor can have openings cut where the pillars will stand, excavate and pour new footings for the pillars - with the J-bolts jigged into position - for less money than a complete new floor. After seeing the bend of the lift arms under your lightweight pickup I will be ordering a 4 post with track jacks for lifting my one-ton diesel pickups.. Half a lifetime as an engineer in heavy industrial manufacturing plants has taught me the hard way that, if something mighta possibly, sorta, coulda happened (no matter how unlikely) it will. It's only a question of when.

[@vandalsgarage]

A 4 post lift is great for vehicle storage, but not for vehicle maintenance. For every job, there's a correct tool. A lightweight 2 post lift isn't the best choice for heavy diesel pickups, but the answer isn't to go to a 4 post, the answer is to upsize the list to a 12k or just buy a better lift. I use a Mohawk 10k 2post lift for my 8000 pound Ram pickup, and its rock steady

[@roberts5118]

Absolutely DO NOT cut openings in the floor and pour new footings where the lift pillars will stand. Your J-bolt idea isn't bad if you can lift the pillars into the air and drop them over the bolts sticking out if the concrete, but to tell someone that has too thin if a concrete pad to simply cut openings where the lift pillars will stand and excavate and pour new thicker footings only under the pillars is completely unsafe and ridiculous to save money. I don't know where you got your engineering degree but I sure as hell wouldn't be working under THAT lift! You need a complete new floor there's no way around it. The entire floor slab is where you get the strength. Simply cutting holes in thin concrete and putting the lift posts on thick stilts is the stupidest and most ridiculous advice I've ever heard. It will undoubtedly topple over. I have NO degree in engineering and that's my advice.

[@michaelforansich8090]

Nice, very nice! I would add that for anyone, if you are replacing your concrete slab, to lay a 600mm x 300mm x 10mm thick MS steel plate under the location of the columns, embed in and flush with the concrete (made it dead level - very easy to do as can be tapped mm here or there). That totally destresses the area (UDL vs point load) under column, and will be full contact with column baseplate, so virtually every failure mechanism will be avoided. Also do that if you have minimum concrete thickness, just grind down 10mm and epoxy under the plate to fill low points. It's all about maximising surface contact to spread the load. AND it's way better than shimming - a practice that leads to more cracking failures from my experience. If you can not put a steel plate down, and your column base plate (or the slab) is warped then grinding out a little concrete is still preferred, use the wet paint method to tell the high spots. Note drilling holes through the 10mm steel plate - either making them align with concrete holes after is ok, but easier to put holes big enough for anchors to be drilled in concrete through the plate.

[@richardsperry3310]

I did the exact same thing in my garage when we moved to this house in 2008. Excavate, rebar, 4000psi concrete, wait 6 weeks… best upgrade in a garage I’ve ever done.

When you installed the shims, the overall force, and hence the pressure will be on the area below the shims, not the whole lift pad, so the PSI value should be taken for area of the shim, not the pad..

The marketing department rounded this down to 4 inches of course and boom, sales are through the roof.

[@vanlifebiker]

FYI torque specs come with anchor kits. If the anchors came with the lift I'd just look up specs for same diameter anchor with reputable company like Hilti for example. Personally I would have poured 2 footings where the columns bolted down instead of redoing entire slab. Would have been cheaper & stronger IMHO. Been in contruction for 30+ years. Glad you mentioned you did allow concrete time to cure. 😎👍

[@xenonram]

It wouldn't have been much cheaper. Maybe $50 less concrete and a $100 less labor. And it most definitely wouldn't have been stronger. It doesn't take much more for the contractor to do one larger pad. Maybe 20 min more on the machine, and less small cuts of rebar. The holes for the rebar pins you would save in the middle of the big pad will be eaten up by the inside sides of the two small pads. It's minuscule.

[@g-riffin]

Brian: “good job making that decision” Zach casually says, “ staying alive is important”

[@briangc1972]

The website specifies minimum 4" of 3000 psi concrete. The psi rating and amount of rebar make a huge difference as far as how thick it needs to be. Many garage slabs are made with 2000 psi concrete and no real substrate. That would explain the 7" spec you mentioned. A cheaper solution to questionable concrete strength is to weld a 30" long by 14" wide 1/2" steel plate under the posts. That will spread the load and stresses out farther. Install the factory anchors as in the plan and add 8 more anchors in the new plate (4 on each side). If you tear up and pour a new concrete floor, you have to wait 28 days for the concrete to cure before drilling any holes in it.

[@skliros9235]

Most residential garage floors will be poured 4", so plan on redoing the concrete if you are putting a 2 post lift.

After working in several rehabbed shop buildings and seeing many floors crack because of thin floors I've always told people when in doubt install a 4 poster, it doesn't require a thicker floor because it sits on 4 points and not dependent on a 2ft pattern of bolts to hold the weight. Especially if the car start rocking. As far as the low ceiling, I've worked from computer chairs and used ratchet straps to lower transmissions & differentials from under low cars.

[@hritishhemraz8924]

[@scottpecora371]

Regarding the concrete thickness: Another option may be to obtain a 1" thick plate of steel to dimensions that would double the square inches of the footing so your anchored to twice ot more of the floor and it distributes the load over twice or more of the foot: so the uplifting force on the bolts are spread or a much larger footing

[@markanthony3275]

Exactly. When I buy the hoist I'm looking at , I want them to lengthen the footing of the towers by 100%...and if they won't, then I will have the footings made up out of plate and attach them to the concrete, and then weld or bolt the towers to the plates.

[@JMNTN]

i always find these 2 post lifts without a top piece sketchy. They probably won't fail but if the tops are connected it adds so much strength

[@jbdragon3295]

I used these type of lifts for years here in CA without issue. Having some heavy-duty bar going across to add strength would really limit what you could do with a car. Normally the car or truck can be above those posts. If there is any type of bar going across, that is your height limit now no matter what. Really wouldn't do all that much anyway. These type of lifts are quite safe so long as you mount a car/truck on them correctly and is in 100% working order so it doesn't fall off the lift. Even then the lift is not going anywhere, just the vehicle. These days I no longer work on cars. I work at a Food Factory and have installed a number of Industrial machines and used quite a few of these anchors. The important part of these lifts is the thickness of the cement. I remember at work when we were getting a new 2-post lift they also cut out and pored a much thicker pad for it. It's still there and been in use for around 20 years. A bar on top wouldn't do anything to stop a tower from falling over because of too thin of cement, or anchor failure. I haven't seen any anchors fail before. I'm using Stainless ones normally. They are also going through tile before going into the cement. It's a washdown environment and lots of chemicals used and RUST is something to avoid. I also use some type of silicon in the hole and around the anchor to help keep the water out.

WOW! seriously what a great how to on the actual lift i was interested in purchasing. as a side note those toggle or red head style bolts have a tensile strength of at least 180ksi unless you could get them into bending which you can't with those base plates you could never fail those bolts doing their jobs, the concrete would way before fail and break up. then re-doing the floor on your build as all have said "4" is at best sketchy" then finding how thin your slab was was a no go, also most garage slabs are not properly rebared to be strong enough to begin with thicker or not. the overhead trussed lifts makes a big difference on how those uprights load, and bow in even when you center the CG over the uprights. you see the flex of the uprights allot more without that overhead style cross member lifts but those you cant use in low ceiling heights period. i really appreciate the no hype no attitude you and your friends bring watching you guys work and do the job along with the explanations of what is going on. most others hype and carry on until i have to stop watching them or suffer though hoping they will actually tell you something other than allot of mis or no information just look at me, am i cool or what? again big thanks really appreciate you and what you presented here.

That’s not how wedge anchors are intended to be used. Additionally, it would be very difficult to get them set in the proper position AND set the lift post on top. These posts are massively heavy.

[@Aragorn450]

@@coreyscarrepairs Forget my last comment, my brain is foggy... So, putting them in wet concrete would necessitate different types of anchors. You're right, you can't use wedge anchors in wet concrete and I wasn't suggesting that. But there's anchors that are meant for wet concrete that would easily be used instead. As for alignment. This is something that's done all the time. The easiest would be to use a steel base plate that gets embedded into the concrete too that has the anchors going through it. Lastly, these are meant to roll into place, and there's play in the anchor holes, so you'd just roll it into place and then angle it vertical with the anchors going into the holes as it gets lifted vertical.

[@donaldholzschuh6728]

I ran into a similar problem for one of the 2 posts for the Max-Jax lift I bought. I had a good 4" plus for 1 post, but the slab was about 3" for the other post and the shields would not grab. My solution was to cut out a 1' x 1' square of the existing slab, and dig down 1' to make a foundation to support that one post. I added a tic-tac-toe pattern of scrap re-bar pieces I got from a local job site. I was able to work the re-bar under the surrounding slab. A couple bags of Sakrete high strength 5000 Plus concrete mix and the problem was solved, albeit a bit overkill. Keep in mind that most garage slabs are poured using a frame made of 1" x 4" - which is actually 3/4" x 3-1/2", so the slab is likely to be closer to 3-1/2" thick. By the way, I have a 10' ceiling in my shop, and the Max-Jax is perfect for that application. I have lifted from a BMW Z3 to a Dodge Ram 1500, and much in between. A low ceiling means you can't stand under a vehicle. My lift came with a rolling seat that lets me scoot around under a vehicle with just enough head clearance. I've serviced a transmission, rebuilt a couple of front ends, several brake jobs, axles, etc. I would have avoided doing many of those t asks without a lift!

[@jcapita156]

I would recommend taking those concrete anchors for the columns up to 150ft pds as my dad is a certified lift installer and he always puts them at 150ft pds no matter the make of the lift. Again just a recommendation but overall a very nice install. Also they make an over head cut off kit to keep you from going too high when lifting a larger vehicle with low ceilings.

[@OU81TWO]

The torque requirement for anchors is specified by the manufacturer based on the anchor material and pullout resistance of the concrete. It has nothing to do with the lift itself. A 3/4" wedge anchor in 4000psi concrete will pull out at about 12000 Lbs of tension. The weak part is the concrete and not the anchor. Torquing up to 150 ft lb will exceed that max pullout capacity of the concrete. You don't typically torque wedge anchors the same as you would a bolt or nut. Those 3/4 anchors are typically torque to about 110 ft lb. If your dad is going to 150 ft lb with 3/4" wedge or chemical anchors then he's doing it wrong.

So many people skip the step of tying back into the existing slab with rebar, and one side would settle causing the lift to twist if its an overhead. This one being a baseplate isn't free from those issues just because it isn't connected at the top of the posts. If you have a settling issue after a solid slab pour, you can simply disassemble the lift and fix the pad, the lift won't be damaged. If you do two pier's, you only have a small gap between of existing concrete. Might as well clear that out, it's not much more money and your already going through all the work.

[@blueskytoday2230]

Came here looking for this. Why in the world would you not install footers tied into the slab and studs for the lifts? Wedge bolts for a lift? Yeah, that's 'standard' and the web is full of examples of how these things pull out over time. Hell, I'd connect the footers with a beam just to be sure. The additional cost in nothing relative to your life

18:30 Jerry says it has taken them 2 days to complete it.. But the whole process was more than 2 months...Lol, 😆😆😆

[@traildogadventuresoffroad1245]

Just did a pour for our shop build, we did 2 4 x4 x 14 inch deep footers for the lift ( a 10 k 2 post , Rotary brand) the rest of the slab is 5 inches, a little overkill is never a bad thing when installing a lift.

yup check the torque on the bolts every year as well. I know its been a few months since install but in commercial projects, yearly special inspection should be done by the owner on anchors. With wedge anchors, these are 3/4 Diameter, probably some Chinese BS non the less, should be torqued down to 110lbs per sf. If unsure, check the ESR document for that particular anchor. Also with wedge anchors there is specific spacing between the c/c of each anchor as well as edge distance. If you were using a Powers SD1 anchor, I wouldn't used a wedge anchor if you were withing 16" of an expansion joint, which maybe you are not. You could go down to 11" at a minimum though but its your choice. If it was me, I would use b7 rod and a adhesive anchor either Hilti say "hit200 or powers ac200. You would also want to have the anchors spaced a minimum of 6" apart from each other. Just becuase you have 8 holes in the base plate does not mean you have to use them all, normally you would want to use the extremities and if you were trying to hit that minimum edge distance you could go in a hole. More anchors does not mean more holding power, it could in fact reduce the effectiveness of the anchor.

I installed my Atlas lift back in March and I love it. I’m in a wheelchair and I love doing all the maintenance work on both my car and my wife’s car. But I went with a four post lift because quite frankly two post lifts scare the hell out of me. I feel much safer being under my four post lift over a two post lift. My garage ceiling is only nine feet tall but that’s not a problem with me. I don’t need the lift to raise my vehicles very high because I’m in a wheelchair. This means I can easily roll around underneath my vehicles and do what I need to do without any height issues. I posted a short video of my lift if anyone is interested in seeing it. kzbin.info/www/bejne/rHKtlnenf7Zqa5o

"better safe than dead". Lol Too bad they didn't compact the soil first. A lot of contractors are lazy when building houses and throw concrete over with out compacting, and that's where you see over time the drive way settle. But the garage hopefully was poured as part of foundation and they usually compact for that.

[@Jerry-ko9pi]

That was a error since 4 & 7 atre close to each other.I have been thinking about installing a lift myself, but my garage floor is sloped, so I would have to wait till we move and build a garage. Then I would make my floors thick enough in 1 bay to support a lift.

[@macbookpro57]

My dream is to have a lift one day. The height of that garage is pretty short to take advantage of a lift though it’d say

[@rosewd2]

Thats good, i like how you drilled the rebar into the existing slab. I like the drive on 4 posts lifts better, with the rolling jack to take the wheels off.

"We are converting from metric to imperial." .... WHY? You love doing fractions?

[@MattyH73]

Cos they are Americans

[@fakename287]

Metric tape measures aren't as readily available as imperial ones in the states, it sounds like the instructions were metric so instead of going out and shopping for a metric tape measure they just converted to imperial and used what they had

[@TranceEmotion]

@@fakename287 I work in the Oil Industry here in Canada and i still remember the first time as a first year Apprentice that my journeyman gave me a measurement in Imperial and i went whaaaa? (Since we only learn Metric in school now) Luckily we all carry dual measurement tapes since we deal with both Imperial/Metric stuff on a day to day basis.

[@dennyoconnor8680]

Because we are capable of doing fractions (do them every day) . For real fun naval architect plans are in 1/8" dimensions. AN bolts in aircraft have their own rules. I also can get by in drams, gills, pints, gallons, hogsheads, bushels and barrels for volume - as well as ten yard loads of gravel. And grains, ounces, pounds, tons (long and short) as well as kilograms. Also unbothered when faced with watts, joules, kPa, Nm, inch pounds, foot pounds, and on and on. Conversions are a way of life if you are doing anything in the science or engineering fields. Now being flexible I would have simply used a couple of metric rulers (already have them) as you are suggesting. All the home improvement stores, hardware stores, auto parts stores in the US sell metric rulers these days.

[@thewholls7176]

This is why I bought a scissor lift because the footprint is okay on thin concrete but some two post choice these days come with a thin concrete kit as an extra and I’m guessing it’s just a square section of checker plate to spread the load

Good DIY video. I've been researching lifts a lot. Yes the 10k lifts that I read about do require more than 4" of 3000psi concrete. I'm looking at 9k lifts and they call for 4" 3000 psi concrete. I called my concrete guy and he said my floor is 4" thick and 3500psi concrete with rebar reinforcement. Hope i don't drill into the rebar 👀

Interesting video. I'm hoping to install one of these in my new place not long after I get settled in. I'm not an installer, nor do I claim ANY sort of expertise or even any experience with installing these lifts, but I one thought about your installation... In the interest of economy, but still being safe, I wondered why you tore out and replaced the entire section of floor instead of just a strip of the floor, or even just a couple squares where the uprights go...

[@audtinbeckwith7005]

For rebar to add exstra strength one square can seddle to easily u see how they put rebar in the sides of the slab that was still there it’s to add more integrity

[@chrissayers7076]

Great video, I think I would install a device that senses when the vehicle gets close to the ceiling, I would use bumper reverse sensors mounted to the ceiling.

[@goalie2998]

It would be an easy modification to add a limit switch that stops cars from going too high. A simple way which wouldnt involve breaking the internal circuitry would be a limit switch wired to a 2 pole rib relay which kills power to the lift. If that limit is hit manually lower the lift then power is back on.

[@danishafnan7623]

Could you have poured footings instead of the entire pad? I would have gone with footings similar to the columns with enough footprint. Thanks.

[@peanutbutterisfu]

I’m not a pro but I’ve installed a bunch of lifts they usually come with anchor bolts about 5in long which are probably fine but I always get longer 7in anchor bolts. When I pound the anchor bolts in I put the nut on the bolt flush then when it’s all the way down I back the nut off about half way and pound it in more so when I torque the nut down the bolt usually is only sticking out a little bit past the nut so the anchor bolt is as deep in the concrete as possible.

[@PencilGlue]

Well the thing that bugging me that how will you hide all those gadgets from your kids when you have them.?

[@mjktrash]

While I don't believe you have an issue with the hardware of your lift, I don't exactly agree with your interpretation of the PSI rating of the concrete. Concrete does not have the same PSI rating in compression as it does in tension. In fact it is radically different. You can compress the hell out of concrete, but you can't pull on concrete with nearly the same force. So while the expanders at the bottom of the concrete anchors have several aspects to them, as they expand outward (compression - good), the force pulling "up" on the concrete is partially in tension (bad). This is one of the factors in why there is a minimum thickness requirement for these kinds of lifts. Excellent choice in replacing the slab. ;)

[@tokuzumi1]

I'm not sure why you couldn't have just make two small footer pads for where the posts would attach. Cut 8" around the footprint of the lift stands, and pour a deep slab only on those two spots. Seems like a 15x12 slab was a little overkill.

[@fakename287]

@Mario plus the fact that if it's just two small slabs taking on all that weight instead of one whole unit you run the risk of the tiny slabs shifting

[@MOAB-UT]

4k lbs. is the "compression" tolerance. The bolts are also designed to secure the "tension" load (pulling/twisting) up and out. Concrete is very strong with compression but quite weak with resisting tension. It was a good call installing the new concrete. Too bad the bolts weren't a little longer to take more advantage of the full depth of the concrete. I would have made the new pad larger (wider and longer.) I don't really like the edge (weak point) being so close to the lift. OEM calls for a full slab- not a repaired slab. I agree though, what you did is likely much stronger than using the original slab which was only 2" in some spots.

[@spencerrr9878]

[@DH-ik1vf]

Good judgement on the slab upgrade. Could have placed thickened slab at the post locations and set j-bolts in place during the pour.
