Safety has nothing to do with lifting a vehicle backwards or not on a asymetric lift. The center of gravity is the only important thing to respect,and it must be at the same distance between the short and long arms,so offset relative to the columns towards the longest arms The center of gravity is different on front wheel drive,rear wheel drive,or even loaded or not vehicles,so "backwards" has no sense in itself.
In the UK we use these either way all the time Chris, obviously common sense and a 'rock of reassurance' play a big part, been in the game 30+ years now and never had one fall off.
Perhaps but you’re causing excessive wear to the rear arms and carriage slide blocks. If you want to back into a A symmetrical hoist you need to switch the arms.
Asymmetrical is for ease of entry/exit into the vehicle. Look at your google snap shot. It allows the posts to be further forward in relationship to the doors, letting the doors open much more freely. Typically the front of vehicles is heavier (front is closer to the posts), and the rear which has the arms extended more has less weight. Definitely makes sense to load them forward only. However, being that your total load is well under the capacity of the lift the now rear weight bias is still at an overall acceptable level. And 4 points is 4 points, rear facing doesn't make the car less stable that's not the issue really, its the heavier end being further from the posts then when forward facing.
I work in a funky small shop. The owner installed 2 asymmetrical lifts in a way that we almost have to use them backwards. Honestly, i want to hate on it but it works perfectly fine. Some cases better. I dont know, dont do it, but if you have to, do it. It's been over a year since they were installed, thousands of cars up and down, no issues so far.
Congratulations for hitting 500k subscribers Chris well deserved,thanks for sharing your awesome videos,I never really watched W.D after he destroyed that classic Dodge Charger made me sick to my stomach.
Thanks man! And thanks so much for tuning in. I actually don't watch his videos either. But they do pop up and sometimes I'll skip through to see the carnage.

Exactly how I feel. However I have seen quite a few comments from people saying it shouldn't be done. I'm curious to hear if anybody has additional information that maybe I'm missing.
The lift has no idea which way around the vehicle is, all it knows is that there is an imposed load and it has to lift it, so long as the mounts are positioned to allow for equal weight distribution then the lift is an inanimate object - unless it had some sort of load calibrator - then a load is a load and doing what you do to test is sensible and the provision of additional supports when really wanting to heave on the vehicle would make sense when working directly underneath.
@@nnkhmiscthe A symmetrical hoist is designed with the majority of the weight to be forward if the columns to give the tech maximum space in front of the vehicle for his tools and work space. The way he has his tundra loaded the rear arms could fail, or anchors and concrete could fail. He would need to swap the arms and move back more.
Hey! Hello Chris and Jen! I used to put vehicles on backwards on occasion. As you said , use your noodle when you do so and make sure that the front of the vehicle is back far enough and think about the weight distribution. And remember that it is always better to error on the side of caution!
I have never even used a lift but my common sense is saying that you want the vehicles center of gravity as close to the posts as possible. This causes the smallest amount of stress on the posts and floor bolts.
I use to undercoat vehicles at a local South Jersey dealership back in the 80's/90's. Lifting old school suburbans, conversion vans, and old Cadillac's was always sketchy.
20 plus years ive never had a lift awear of the direction of the vehicle properly balanced is properly balanced and rotary lift have always served me well
Come on Chris... you are killing me, man! Please make a longer video because we all enjoy your content. It is like a fat man sitting in a candy store and can't indulge on the goodies.
I always enjoy your videos Chris, keep them coming. I’ve used Rotary for years, nearly bulletproof. It’s not the lift arms or hydraulics that would concern me, it’s the attachment to the floor. If the center of gravity is too far out of the design window the chance that a weak anchor or crack in the concrete can cause a cascade failure increase well beyond my comfort zone.
I have been installing rotary hoists for 5 yrs. You have to switch the front arms with the rear arms. Because your overloading the rear arm and moving the center of gravity you could damage the rear arms, but unfortunately you don’t have enough space in front of the hoist to fit your truck that way. The lift capacity is regulated by a pressure valve in the pump. When rotory has there hoists certified by ALI it has to pass a structural test of 1.5 times its lifting capacity to be certified. There is a way to convert your A symmetrical hoist to symmetrical or standard setup. You need to use spacers (black pipe) for your cables, the overhead needs to be lengthened, buy new front arms because short ones won’t work.
Seems like that google post is confusing LENGTH with WEIGHT. The WEIGHT needs to be on the SHORT arms of the lift so most weight will be closest to the posts. The danger is that the post anchors can fail and let the whole shebang tip over- and that anchor failure will NOT show any symptoms until it lets go completely! The arms are not your weak link, it's the anchors. The sway you see at the top of the columns is a sign of the stress on the anchors....That said, the engineered safety factor is probably well past the load you have given the lift- company lawyers are allergic to lawsuits! Bottom line: you probably are not exceeding safe limits, but it's definitely something to be verrrry careful about...
I have two Bend Pacs in my shop. I have tied them to the building on the tops of the lifts. Think how much leverage there is on those anchors when your rockin that vehicle. Capturing them at the top limits greatly how much they want to pull on the anchors. I recently moved one of the racks and this time I used Hilti epoxy instead of anchors. Technician Red has a great vid about epoxy anchors. Mine r both asymmetrical. I often put small cars on backwards. Never big stuff!!!!
Reminds me of a joke I saw posted on a bulletin board when I was in the Navy. It was a 747 landed on an aircraft carrier. In the cartoon picture, one of the wings had knocked off the bridge mast of the ship, the front of the ship was sunk down to the water line barely afloat. And the caption read, from the pilot. " I told you I could do it". The moral is. Just because you can, doesn't mean you should. 😎
The answer is that it depends. If your asymmetrical lift has a tilting carriage, then putting a vehicle on backwards carries a risk of it sliding off. Your lift appears not to tilt, so as long as the weight distribution is good, you should be fine.
Guys in the shop where I work use those screw jacks under 3/4 & 1 ton flat bed farm trucks all the time. We also have the heavier duty tripod jacks for the bigger stuff
My thoughts are that the lift does not know which direction you put the vehicle on. If the weight is distributed evenly as common sense requires, doesn't matter which way the vehicle is facing.
I know first hand that a lift will raise up way more than it’s supposed to and the anchor’s pulled out of the concrete and dumped the truck but didn’t hurt the lift.
i put a 2tonn electric car backwards onto a shitty stertil koni lift once the lift was chain driven so only one side had actual hidraulics ended up snapping the welded bracket that the chain threaded into it made one hell of a noise 🤣 those koni lifts where rated for 3tonns and are now out of production, they also had alot of problems with the auto locks not wanting to disengade summorise: dont do it with heavy cars on shitty lifts :)
Are the actual lift arms different lengths? If they are then that would be a factor, otherwise you are right about just working the center of gravity. And btw- some brewing company in Ohio is making a PB Blaster Beer and It looks exactly like the spray. You of all people need to get a six pack of that! It would look like you are such believer that you drink the dang stuff!...
News to me lmao. I've lifted many vehicles backwards for different reasons such as rear diff rebuilds being closer to my box or no starts that had to be pushed in where turning it around is just a giant pain in the ass.
As someone who has absolutely no experience with lifts my expert opinion is ... I have no idea! Love your videos tho Chris and I wish you and Jennifer the greatest success!!
It the leang th of the lift arms is where u cant lifta car backwards, that thing is only bolted, it will pull up out of the concrete, too much rockin will pull them out, and down it comes, been cranking wtench along time, and ive seen them fall, useing them right,
My thoughts are with an asymmetrical lift with the long arms in the back, and the heaviest portion of the vehicle farthest away from the mounting points of the lift to the concrete. Is it a worry that with the vehicle, all the way up in the air angle of force would it try to pull the lift out of the cement with hthe majority of the weight being farthest away from the centerline a lift. Regardless of center of gravity . Center of gravity on that truck is behind where it is on the lift. We use both types at work . I regularly use a 12k and 18k symmetrical working on superdutys and vans . Only use asymmetric for lighter weight vehicles .I wouldn’t be worried about the lift as much as i would be about pulling the lift out of the concrete with that much weight past the center of gravity. I feel like there is a reason they dont make large weight rating lifts in an asymmetric design regardless of how you position the vehicle on the hoist. Really it should come down to center of gravity line. If you put it on backwards make sure its center of gravity is where your lifts is weather its 6” or 18” behind lift posts. Not easy to do when front arms are short trying to reach a frame or leaf spring on a truck 🤷🏼♂️
I'd been looking into putting in a lift and frankly, all of the hassle has led me to seriously look at using a pit instead. Good excuse to put in a nice looking shop floor at the same time too.
everything is always under rated. working loads are always lower to fail loads not even close example say a 3/8 ropes working load is 350 pounds of weight. the breaking rope would be over a 1,000 lbs or better. or a bumper hitch. say it says 2,500 pounds i dont know how many times i had triple the load on that bumper when pulling a trailer. i didnt make it a habbit but there where times i thought i had no choice when doing a job. but later went to a frame hitch once realizing that would be the trucks new working load
I remember way back when watching a safety video that showed you could safely lift a 10klbs van but then put a 8klbs Cadillac convertable on the same lift and have a failure , simply because of the extra height clearance and rigidity difference of the vehicles … leverage and applied physics plus engineered margins of safety make it more about service life and less about the idiot in charge these days😊
Technically you can take those lift arms and put the long ones on the other end left on right right on left and it becomes the right way if anybody wants to complain I've done a tuna shop but you could take those pins out and move those legs the other way is if the lady you were driving in the correct way instead of facing the wall and it will work
The Rotary SPOA9 and SPOA10 are great lifts. I have one of each in my shop. I’d actually like to get rid of one of my above ground lifts and replace it with an inground lift
Thank you. Of course you can lift a car or truck ,backwards. The reason they are lifted not backwards, is because of the relation of where the tool boxes and other items in the garage are located. Jack stands are always a safety precaution. Keep on making great entertainment and video's
I have loaded multiple vehicles backwards on my asymmetrical lift...manly when I do motor swaps..toyota pickup jeep cherokee and comanche....it works 😊I purchased lift jack stands from horror freight....
i have the same problem and ive been putting the cars on backwards for my whole life i just switched the arms put the long ones to the front of the lift and the short to the back and should work no problem
I think you should consider the price of stands, what you could sell the lift for, and if finances allow buy the 4 post lift that Vicegrip garage uses. It would probably worth it in the long run. Way safer, moveable to new shop when tome comes, moveable in and out of shop. Could use in driveway for power washing under carriages, and it would come in handy for boats and bikes.
It's completely fine the way you are doing it. Especially if you stabilize it while at working height. Unless the concrete fails it should always be safe. You will likely see some added wear in the upper carage area. Possibly premature roller failure. Just check on it every so often. I always like doing a clean up, grease and over look once a year .
this isn't hard to understand. Each lift arm is capable of 2500lbs on a 10k hoist. That is what is considered safe working conditions. The total doesnt matter if you exceed the individual lift arm weight capacity.
I would say it has more to do with the anchor to the floor than the arms of the lift. Ideally, you want the center of gravity as close to the posts as possible, and mounting a vehicle backwards will position the COG further away than what is ideal.
Does the manual say not to put Porsche, Ferrari, or other rear engine cars on it? Your methodology seems solid. However, looking at the post locations at the control joint and watching you shake it I’m thinking it would have been good to have a little footing (thickened slab) under the posts and some rebar in the slab under them to pick up those loads.
The asymmetrical is for door entry. Doesn't matter about the position of the vehicle. And all these hydraulic lifts have a safety valve inside. It won't lift it.
It will be fine as long as balanced. I had installed a hoist that could be installed asymmetrical or not. I installed it normal but still have shorter front arms than rear and lift everything without any problems.
I realize your in a compact environment but the Wildfire (4) post lifts can roll out of the way if you need more open space, they also have a separate rolling jack lift device that can point lift anywhere along the length of it along with a handy built in rolling tool tray. Lastly you can (confidently) park another vehicle underneath this brand of lift. You should check em out heck they may even sponsor your channel, they’ve done so for other YT channels.
@@delgrangos1859 Not all together true. Most are not designed to be mobile. The Wildfire happens to be mobile, but even they will tell you that you should move them as little as possible. The drawback to the wildfire is that there are reinforcement straps across the floor, which are constantly tripped on and collect filth and small parts. Proper 4 post lifts are point mounted for an open, trip hazard free work area beneath, as well as higher capacities for larger vehicles. The wildfire lifts are considered by most to be a light duty hybrid lift for the guy who wants to work on his car in the air, and also needs to stack cars for storage. This is from the salesman I spoke to about additional lifts in our shop, and he happily (because he had integrity) talked me out of them. Good company for sure, wrong application for commercial use.
Does look like you need to retighten the base. I got a Danmar 10k symmetrical and I don't think my beams rock back and forth that much with my 2500 Silverado on it.
26 years as a technician and it totally depends on the car and if it's heavier on one end or the other. If you shake it and it doesn't fall your good 👌
Why do they design these 70-30? The balance line for weight distribution can be found for most cars. Make the lift 50-50 and set the cars balance line between the posts.
glad to see you have a fire extinguisher handy. never can have enough of those. but i use that type as a last resort. always keep a water hose handy when ever doing hot work. its an unlimited supply. the powder is a major pain in the ass. you never get it all out or off of what you spray it on. just sharing my experience on putting out fires in automotive and industrial settings. like for example a steel mill ISG Conshohocken mittal steel now. they used extinguishers as a last resort. but we also used water. even those there was greases and oil every where. the extinguishers will put the flames out. but it wont put out whats smoldering. and it will smoke and relight again and again. even as a fire watch i noticed working at many sites. DuPont's as another chambers works. we would demo steel structures systems. and always hosing anything that was cherry and smoldering. and using extinguishers ... well you'd be better off pissing on it. it will reignite if you dont use water. just a little useless info. but wanted to share......AS FAR AS THE LIFT. IT DOESNT MATTER WTF PEOPLE OR MANUFACTIRER SAY. common sense put it on the lift and do the shake test every time. never had a car fall off ever. but i always did the shake test.
I do it at shop if a car comes in on the hook that don't run I just have it dropped on the bay. Some are backwards but my bendpak 10k lifts almost anything and my atlas well that's another story
I think if one could somehow accurately determine the centre of gravity and using that information to determine where to position the lift arms, it should be safe. 👍
Backwards puts the weight further from the posts which puts more strain on the anchors imo... my brain would make me turn the whple thing around and reanchor it if I wanted to back vehicles in...
@@nnkhmisc yes... when I said weight I meant the heavy end... the engine weight should be close to the posts not hanging out away from them putting more strain on the floor anchors
At 6000lbs that has to be lightest Submarine on the planet. 💯💪

Sounds like a test for Project Farm. He would be my pick to torture test some lifts

i have the same problem and ive been putting the cars on backwards for my whole life i just switched the arms put the long ones to the front of the lift and the short to the back and should work no problem
I think you should consider the price of stands, what you could sell the lift for, and if finances allow buy the 4 post lift that Vicegrip garage uses.
It would probably worth it in the long run. Way safer, moveable to new shop when tome comes, moveable in and out of shop. Could use in driveway for power washing under carriages, and it would come in handy for boats and bikes.
we use to do it backward every week at VW dealer for multiple job. nothing bad never happened but like always you need to be careful
It's completely fine the way you are doing it. Especially if you stabilize it while at working height. Unless the concrete fails it should always be safe. You will likely see some added wear in the upper carage area. Possibly premature roller failure. Just check on it every so often. I always like doing a clean up, grease and over look once a year .
The Intronetz said I couldn't run 32ACP in my 327 Federal Magnum revolver and yet it works fine for me. We learn at our own risk.
this isn't hard to understand. Each lift arm is capable of 2500lbs on a 10k hoist. That is what is considered safe working conditions. The total doesnt matter if you exceed the individual lift arm weight capacity.
I would say it has more to do with the anchor to the floor than the arms of the lift.
Ideally, you want the center of gravity as close to the posts as possible, and mounting a vehicle backwards will position the COG further away than what is ideal.
Asymmetrical lifts are designed to have the center of gravity behind the posts
Does the manual say not to put Porsche, Ferrari, or other rear engine cars on it? Your methodology seems solid. However, looking at the post locations at the control joint and watching you shake it I’m thinking it would have been good to have a little footing (thickened slab) under the posts and some rebar in the slab under them to pick up those loads.
The asymmetrical is for door entry. Doesn't matter about the position of the vehicle. And all these hydraulic lifts have a safety valve inside. It won't lift it.
It will be fine as long as balanced. I had installed a hoist that could be installed asymmetrical or not. I installed it normal but still have shorter front arms than rear and lift everything without any problems.
3am?? Chris goto bed!!!
Get some sleep 😴🥱
I realize your in a compact environment but the Wildfire (4) post lifts can roll out of the way if you need more open space, they also have a separate rolling jack lift device that can point lift anywhere along the length of it along with a handy built in rolling tool tray. Lastly you can (confidently) park another vehicle underneath this brand of lift. You should check em out heck they may even sponsor your channel, they’ve done so for other YT channels.
You just described nearly all 4 post lifts.
@@delgrangos1859 Not all together true. Most are not designed to be mobile. The Wildfire happens to be mobile, but even they will tell you that you should move them as little as possible. The drawback to the wildfire is that there are reinforcement straps across the floor, which are constantly tripped on and collect filth and small parts. Proper 4 post lifts are point mounted for an open, trip hazard free work area beneath, as well as higher capacities for larger vehicles. The wildfire lifts are considered by most to be a light duty hybrid lift for the guy who wants to work on his car in the air, and also needs to stack cars for storage. This is from the salesman I spoke to about additional lifts in our shop, and he happily (because he had integrity) talked me out of them. Good company for sure, wrong application for commercial use.
I’m just an idiot carpenter, but I’ve had my Ram on backwards before with no problem🤷♂️
Does look like you need to retighten the base. I got a Danmar 10k symmetrical and I don't think my beams rock back and forth that much with my 2500 Silverado on it.
I do it all the time
Can you just get that lift turned around to put it in the correct orientation? Would it be worth while if you could?
If there is a front/back, then can't you just unbolt it from the footing and rotate one side to the other then bolt it back down?
Looked good to me, I would work under it.
Mid-ship Corvettes - NO!
Check with Gus.
The front asymmetrical arms are not made to hold the weight. Many cases where they bend or break.
They are shorter and the exact same construction as the rear arms. Which means they can take more weight before they bend or break.
26 years as a technician and it totally depends on the car and if it's heavier on one end or the other. If you shake it and it doesn't fall your good 👌
Figured I'd load it backwards, shake test it, if it doesn't fall off run it. I'm at work tho, so I'll let ya know if I get fired or not lol
Is there a reason you can’t turn the lift around so that it’s facing the way you’re going to use it?
I can barely get my car on jack stands
I’ve done it many times with smaller vehicles, never done it with trucks though.
Why do they design these 70-30? The balance line for weight distribution can be found for most cars. Make the lift 50-50 and set the cars balance line between the posts.
For ease of getting in and out of the car without the door hitting the lift post
Btw. can't you just rotate it? I mean the whole lift. Anchor points should be around the same place I guess.
@@nnkhmisc DOH!
A lift in the garage is undoubtedly very good! But it's always better to be safe than sorry. I'll take note of this 🙂
glad to see you have a fire extinguisher handy. never can have enough of those. but i use that type as a last resort. always keep a water hose handy when ever doing hot work. its an unlimited supply. the powder is a major pain in the ass. you never get it all out or off of what you spray it on. just sharing my experience on putting out fires in automotive and industrial settings. like for example a steel mill ISG Conshohocken mittal steel now. they used extinguishers as a last resort. but we also used water. even those there was greases and oil every where. the extinguishers will put the flames out. but it wont put out whats smoldering. and it will smoke and relight again and again. even as a fire watch i noticed working at many sites. DuPont's as another chambers works. we would demo steel structures systems. and always hosing anything that was cherry and smoldering. and using extinguishers ... well you'd be better off pissing on it. it will reignite if you dont use water. just a little useless info. but wanted to share......AS FAR AS THE LIFT. IT DOESNT MATTER WTF PEOPLE OR MANUFACTIRER SAY. common sense put it on the lift and do the shake test every time. never had a car fall off ever. but i always did the shake test.
Can we all agree, having a lift is so convenient?
I do it at shop if a car comes in on the hook that don't run I just have it dropped on the bay. Some are backwards but my bendpak 10k lifts almost anything and my atlas well that's another story
Two things, 1 You were spot on about Whistlin diesel. 2 How deep is your concrete that the lift is lagged into?
It's 6 in thick 5,000 psi concrete with number 4 rebar
I have one and base the decision on the weight of the car. If it's a 3 ton lift then no way would I lift 3 ton vehicle the wrong way around.
Well you put that to rest!!! Next!!!
Chris you have be around lift for long time if you feel safe that is what meters.
I think if one could somehow accurately determine the centre of gravity and using that information to determine where to position the lift arms, it should be safe. 👍
if it fits it ships........
Backwards puts the weight further from the posts which puts more strain on the anchors imo... my brain would make me turn the whple thing around and reanchor it if I wanted to back vehicles in...
An asymmetric lift is designed to have the rear load further away from the posts
@@nnkhmisc yes... when I said weight I meant the heavy end... the engine weight should be close to the posts not hanging out away from them putting more strain on the floor anchors
