No… That is a Jack, NOT a support! Use it to change a tire if it’s your only option. Always put some blocks of wood or even the wheels from the car, stacked two high, preferably. Placed right, those things can save your LIFE!

If you are using a scissor jack to do a risky brake job, at least slide the tire under the frame to keep the car from crushing you if it slips!
The yellow jack stand failed by tearing, assisted by the wedging effect of the rack and cam lock. Whereas the black jack stand failed by tearing by direct force only, so that explains why it was stronger.
Interesting! Surprised the little cheapie did better. I always use stands with higher than necessary ratings. My concerns are side forces and uneven surfaces.

Gl stay safe.
It looks like the rachet one fails catastrophically. after peak load, the pawl can't reach the teeth and there's no resistance. At the end, the telescoping part just drops to the min height
Fazit: Beide entsprechen ihren Spezifikationen, beide haben grosszügige Reserven Conclusion: Both meet their specifications, both have generous reserves
looks to me on the yellow set that the tiny roll pin on the toggle part is the weak point. The cast part was really tough. I was surprised how well the black one did. Cool vid.
The geometry of the yellow one is such that the axis of little roll pin is normal to the thrust on the pawl. The pawl, therefore, transfers the load directly into the pivot pin and through the pin to the vertical tube. The little roll pin is there only to pass the rotary motion of the pivot to the pawl so that the jack can be adjusted by rotating the handle.
@@usernamedaniedmrg The biggest failure of a jack stand is when you do not use them! For them to fail, you have to crush the jack at the same time. My entire car could not crush one of these stands, and I use two, if I am going under the car.
And most importantly - neither failed anywhere near the specified load, they both have a very safe margin. Well, the black one had one design weakness at the top - clearly it can't be used to support even 1T if it's not the right shape, so it's basically single use - but it makes up for it with higher load and better failure mode.
Nice to see this test....and amazing how strong the black one appears to be. I have a pair of stands similar to the yellow ones but only use them if necessary (usually due to limited space)...... I have a large collection of wooden blocks......iron to iron is very slippery!....wood gets dented where pressure is applied;no such risk.... When I jack up a car for a quick job I usually put the wheel I just removed flat on the ground under the subframe or sill,with a wooden block on top it takes more place but is much safer!!
I also use wooden blocks for safety, I learned this from working on the railroad where we used wooden blocks to make sure a 100 ton locomotive didn't fall when we changed out traction motors...
The folding stand is a pretty good design with the center tube going down to the ground. The cheapies they used to sell in the US were open at the bottom. Basically the tube was split to create the legs with a flimsy brace between the legs and the adjustable part in the center. You could actually see it give when being used at the proper weight.
Yep. Generally things are engineered with a safety factor of at least 2x unless it flies. Jack stands get misused alot. Ideally you set them up so they are touching the vehicle or have some vehicle weight on them. If there is too much of a gap between the vehicle and the jack stand the impulse loadings can still exceed the capacity.
Oh it's well beyond 4k pounds. First one did 4200kg. Second one did 7900kg. Times those numbers by 2.2 and that's how many pounds it breaks at. One US ton is 900kg while one metric ton is 1000kg
@@astro.5oh incorrect. The scales were in kg, captioned as such, and relatively close to their 2 ton (2000kg) rating (as labeled on the box and stand) before deformation. Deformation isn't failure and the rating is for maximum weight with no deformation. In this video, it's being tested for max weight before total failure which was 4200kg (4.2 metric tons) and 7900kg (7.9 metric tons). in the second part, it was a test to see how much it'd take to completely destroy a stand which is easier to label in tons as 1 metric ton is equal to 1000kg, but the scale was still in kg. The first one we see captioned in tons was the black stand which reached 14500kg (14.5 metric tons) and 30000kg (30 metric tons)
Thanks for the demo. Everytime a stand has failed for me it was due to sideways/angled pressure not straight down. Usually the stands will twist if they fail.
It also takes up less space in your car's trunk (boot) or tool stand since it folds.... I was very impressed in how much stronger the cheaper stand was!!!
@@johannesthe5th154 I think you shouldn't use a comma for "4.218 ton". But yes, 4,218 kg = 9,299 lb = 4.218 ton (May be he forgot what metric system is? ) Edit: welp, seem like i miss alot of thing.
Wow....I have both styles. I have switched to the yellow one over the last 25, for the 4 legs over three and the top and bottom contact points don't roll over. Plus the more height adjustment spots. The folding black 3 leg was impressive, it has flat base on the bottom, and the folding legs would make it great to leave in the car. I found that on some of my older 4 legs, the box around the wedge finger, on top, had weak welds,and the box popped out. Which happens to be exactly opposite to where the lever pin passes thru the frame, and the hole elongated. I'll be reinforcing that point ASAP. Glad I watched this, on a whim!
Both are up to the job of holding what they say they will but I'd rather have the yellow in the garage with its 4 legs which gives more stability. The folding one would be great to have in your trunk if something happens on/ off road.
I am surprised that the yellow one does not have a pin option as well for extra safety. It would sure make me feel safer since the latching mechanism is somewhat out of view.
I think this isn't necessary, if the jack is under load, the full weight lasts on the latch, so you have to lift the whole weight a centimeter with this small lever, wich definately would require some pretty superhuman strength.
I have a pair of the ones like the yellow one. Mine have a solid steel pin that slides in to aid the ratchet mechanism. They cost like $60 for the pair.
Both stands exhibit small, correctable flaws. The yellow stand has an obvious weakness where the pin passes through the frame. Could easily be improved by reinforcing the holes. The black stand looks really good, however the wings fold early. In a few, very specific, cases this might allow the load to slide off the stand before breaking weight is achieved. Again, could easily be improved. Overall, though, both are excellent performers. I'm not overly fond of the ratchet design but the base is a more substantial four leg configuration (against the three of the black stand). For stability reasons I would probably choose the yellow stand.
@@Garethprice1979 In terms of wobble, yes. However, for legs which are the same distance from the (vertical) center line (at the base), a 4 leg design is inherently more stable in terms of tipping. That's why I used the term 'stability' rather than 'wobble'. I didn't elaborate because I thought it was obvious enough.
The titanic could have easily been improved by reinforcing the holes too. Ha. That old iron got as brittle as an egg shell when cold. I have the ratchet stands. Good to see they over exceeded there specs too
@@Garethprice1979 True, but if it's tilted one leg could see a much higher loading than the others. With the welded 'skirt' of the yellow stand, such an imbalance is partially distributed throughout all legs.
The companies that make these likely create a weak point so that if it fails, it fails predictably and safely under the tolerances they design it for. I’m not an engineer, but it makes sense to me.
Both jack stands supported more than their weight specifications on the press....both have two tons metric = 4,400 pounds load limits. Yellow one held 4.2 metric tons = 9,260 pounds. Difference in price is difference in stability and ease of use. Personal preference...no winner.
I have four of the ratchet axle stands excellent and stable . no worries when working with them supporting my Citroen C5 saloon car . I continue to leave my 3 ton trolley jack in place just for peace of mind .
I had to share this on Facebook, and in that statement I made on Facebook I said I'm looking to buy four of these $15 versions, as I am absolutely stunned and amazed beyond words how strong they are. This is one of the most fascinating and shocking in a wonderful way videos I've ever seen. I also figured out how to do a design improvement on the jackstand that was telescoping? The yellow one? By welding a ring support around that hole where the adjustment pin goes into I bet would double the strength of that whole jackstand. Would love to see someone who knows how to weld do that and then test it to see how much it would take. I'm thinking it would be at least as much as the black folding jack stand, if not a lot more.
I trust my life to the yellow type of jack. I only lift 1/2 of a 3000 pound vehicle. So only 750 pounds on each jack. Thank you for easing my mind about their safety
It would have been more informative to take them to max rated load and see if any deformation occurred. Then, increase loads by 500 lbs until the jack started to fail.
Then, show where and how each could be reinforced to withstand greater loads. Yellow set would benefit from reinforcing the split pin with a solid pin, and added frame washers at the hole for the height adjuster.
I'd be interest to see how these compare with a Weber / AC Hydraulic axle stand with a locking screw thread. This type of axle stand are much safer and allow you set each stand at an exact height - to the millimetre if required.
I would take those jacks back to the store, "I don't know what happened, I left my truck up on the jacks overnight and when I came out in the morning there they were!"
Never cheap out on Jack stands. Had a friend who was almost crushed to death under his truck in high-school because a jack got kicked out and the teeth on his cheap jack stand sheered right off. Lucky his dad was there to get it off of him. Using jack stands properly is important too. They are made to support the static vehicle weight. Impulse loadings from a falling vehicle are exponentially higher.
There is another model which combines those two designs. Yellow one with a pin. I bet it would perform as well as the other one. Also, you guys need to provide a summary of the forces each was able to take at the end of the video.
Yeah that part messed me up quite a bit. Pretty sure that's expected too so arguably choosing to not include that information does not inspire confidence
I do the same. Place the jack stands, load them, then leave the hydraulic floor jack in position as a back up and place timber blocks as well. If I'm raising the front of the vehicle, the rear wheels are chocked and the e-brake is set. The rear of the vehicle, front wheels are chocked. I never use the ratchet type of jack stands, only the fixed design.
@@TheBuccy i do the same! i will put car up on jack stands, have the jack raised the frame height with just a tiny tiny amount pressing the frame just to keep it in place and then ill put one or both wheels under where the frame would land on them if everything were to fail or an earthquake or something
I used to have a pair exactly like the black ones and never trusted them, so i bought a pair exactly like the yellow ones. Same weight and same allen screw set up for the lock, thinking they were stronger. Both were pretty impressive for the price, but wow was I wrong about the black ones.
It would all depend on the brand and the thickness/reinforcing of the metal where the load is applied. Tube around the pin holes for the black one, hole around the pivot for the yellow one.
Considering that a full size pickup has a curb weight of about 5,600 lbs and a full size car weighs in at under 4,000 lbs, either jack is easily capable of supporting the weight of the vehicle. Especially considering it would be distributed between 4 jack stands.
I have similar black ones (red base with black post) but outer post only goes down halfway, and legs are joined at ground level with welded on flat bar, and i also have similar to yellow ones (mine are blue with black post). The black 3 leg type are fine a lot of the time, but as others mention, especially if vehicle up on 2 or 4 of them, are not very stable, compared to using the yellow 4 leg type.(and feel sure my ones would give in much sooner on your press, (also like yours, the tops flattened really easily when first heavy loaded) As both exceed load ratings, i prefer the more stable type, used up to sensible loads, and so recently got a pair of the 10 ton ones as well (blue base yellow post), but may add some reinforcing to the smaller set, now i have seen what gives way first. Good video. Would be interesting to see how some heavier rated ones preform as well.
I'm from Australia so I just wish I could buy any jack stand for $15-25. The yellow one would cost me just under $100 here and would require me to earn over $200 before taxes simply to buy one.
It's interesting to see the ratchet type fail that way. I have a set of 3 ton ratchet ones I use at least weekly. I usually back them up with the twist head style ones as well. I think this video shows you where the failure point will likely be. I'm going to start inspecting the holes the pin goes through for signs of expansion whenever I use them. One thing I want to point out though. In these tests, the load is suspended from above. It presses, but does not sit on the stand. If your car breaks one of these stands, it won't be the same. As soon as a part fails and gives way on the press, the pressure releases until the press can move down to where the stand is now, and the rate of failure is slow. Not so with a car. Gravity will make the result very different.
? this video is scary. they failed insanely low. jack stands are for safety and safety devices should have a factor of 3 to 5. IE 2 ton stand should fail at 6-10 tons. not 2.1 tons.
@@slappomatthew please read my other reply and you'll see that it is indeed failing at much higher than 2 tons. 4.2 and 7.9 metric tons, or 4.7 and 8.8 US tons respectively.
@@slappomatthew dude, who's lifting that much weight with these things? Anyone who's truck is that heavy isn't using jack stands. These jack stands are literally only lifting the front or back half of the vehicle they're under, and for that purpose they're pretty perfect.
The VERY BEST way to support a vehicle in my opinion is to use logs. I used logs that were of varying heights, 12 to 15 inches, they were of a diameter of the same. They were NOT old decaying logs either. My neighbor always had fresh cut logs he would eventually cut up and burn. I would borrow some until I found some that I kept from a tree that had been cut down locally. The price was GREAT, free, and they're better than any jack stands. IF, you buy a set, get some for a truck to use on your car, OR, the most heavy duty you can find if using on a truck. The money spent is worth the life you save.
Looks like either will do a good job of keeping you from dying by being crushed by the car you're working on. I like those folding ones - space saving.
A LOT of car jackstands and floor jacks sold at retail are all manufactured by a handful of factories in China. They are then painted according to the customer. So the only difference between dozens of different brands is the color, stickers, and warranty. What happened with the 3-ton and six ton stands was that the manufacturing production equipment was worn out and some stands failed the load test. Harbor freight recalled them a while back. Now, AutoZone and Walmart are issuing a safety recall on the much more widespread 2-ton stands that are used by most car DIYers.
I really hope you took them back to the store with the original packaging, ask politely if they are supposed to do this after holding up my Honda Jazz?
Nicely shown… I don’t know why I would subject a ten thousand plus load to a single unit , but that most likely his would most likely be shared between two stands and therefore hold up to the average working mans project. Again thanks for the Enlightenment. Awesome on this math!
Imagine taking it back and saying the wife sat on it.Seriously though I think both held up really well considering what they cost and what they're designed to do.
I quit using Jack Stands years ago, not for their capacity but they're small footprint. They are easily unsettled, I found that out after I went to the ER when a 1963 Corvette I was working on fell on me! I have not used one since!
I realized I was unconsciously gritting my teeth and leaning away watching this because I was expecting it to bust 🤣🤣🤣🤣🤣 Y'all watch yourself my jaw hurts now 🤣🤣🤣🤣
this is just about every boy's fantasy. get a machine to crush stuff just to see how much they can take.

And here I thought the cheaper one was bad
I'm no business major, but I think that this might constitute improper use and void the warranty. MAYBE
This is a great demonstration but I feel like people should be more worried about its resistance to weight shifting then it's actual weight capacity.

It's reassuring that both stands failed gradually and gracefully - the last thing you want is something that suddenly goes *BANG* and drops the load.
It looks like the rachet one fails catastrophically. after peak load, the pawl can't reach the teeth and there's no resistance. At the end, the telescoping part just drops to the min height
Not surprised roll pin broke first. It wasn't that long ago those stands were recalled due to roll pins failing here in NZ
The load is not on the roll pin it is only to manoeuvre the chock.
Interestingly, it wasn't the roll pin that failed. It was the sheet metal that held the lever arm.
**Do not repeat this at home**
As if we have a hydraulic press at home 😂
🤣😂🤣😂 I have an hydraulic press at home, is just 10 tons, and I use for my job not for destroy everything 😂🤣😂🤣
it is very easy to make small 16t hydraulic press with hydraulic car jack it is very useful tool
Put a nice cushion on them and let the mother in law check them out
don't try this at home could also mean, in the real world: don't place load greater than rated capacity.
So from what ive seen so far, a 1968 army helmet is better for holding my car up than a jack stand. gotcha....thanks for the videos
"Do not repeat at home"
Oh, okay. This fancy $250,000 commercial-grade hydraulic press that I bought for the house will have go to waste I guess.
Man you overpaid, harbor freight had these fancy commercial presses on sale this week for $279. Rofl

"May I help you?"
"Yes, I'd like to return these."
This is a good lesson in engineering. Just because its more complex doesn’t mean its better.
Wow ... that was a good video. The stands worked better than I expected.
looks to me on the yellow set that the tiny roll pin on the toggle part is the weak point. The cast part was really tough. I was surprised how well the black one did. Cool vid.
Yeah needs thicker steel
The geometry of the yellow one is such that the axis of little roll pin is normal to the thrust on the pawl. The pawl, therefore, transfers the load directly into the pivot pin and through the pin to the vertical tube. The little roll pin is there only to pass the rotary motion of the pivot to the pawl so that the jack can be adjusted by rotating the handle.

Having both types of stand's in my home shop, I'm confident in they're ability to keep me safe on anything I may want to hold up on them.
Famous last words....
They do still fail
Always stick a few cinder blocks under there to be safe
I'd rather screw the car up than lose a limb
@@usernamedaniedmrg The biggest failure of a jack stand is when you do not use them! For them to fail, you have to crush the jack at the same time. My entire car could not crush one of these stands, and I use two, if I am going under the car.
I'd say these stands were designed very well, in that the failure was consistent and non-dramatic.
And most importantly - neither failed anywhere near the specified load, they both have a very safe margin. Well, the black one had one design weakness at the top - clearly it can't be used to support even 1T if it's not the right shape, so it's basically single use - but it makes up for it with higher load and better failure mode.
@@adamkozakiewicz6766 Where these jack stands become particularly dangerous is a shifting-load scenaro, where it puts a lot of weight off center.
That was tons of success on the pin... tons of failure on teeth...

@@darkideas2088 yep!
Nice to see this test....and amazing how strong the black one appears to be.
I have a pair of stands similar to the yellow ones but only use them if necessary (usually due to limited space)...... I have a large collection of wooden blocks......iron to iron is very slippery!....wood gets dented where pressure is applied;no such risk....
When I jack up a car for a quick job I usually put the wheel I just removed flat on the ground under the subframe or sill,with a wooden block on top it takes more place but is much safer!!
I also use wooden blocks for safety, I learned this from working on the railroad where we used wooden blocks to make sure a 100 ton locomotive didn't fall when we changed out traction motors...

The folding stand is a pretty good design with the center tube going down to the ground. The cheapies they used to sell in the US were open at the bottom. Basically the tube was split to create the legs with a flimsy brace between the legs and the adjustable part in the center. You could actually see it give when being used at the proper weight.
Considering that these things only have to take 4,000 pounds, they both seem to be able to do that well!
Yep. Generally things are engineered with a safety factor of at least 2x unless it flies.
Jack stands get misused alot. Ideally you set them up so they are touching the vehicle or have some vehicle weight on them.
If there is too much of a gap between the vehicle and the jack stand the impulse loadings can still exceed the capacity.
Oh it's well beyond 4k pounds. First one did 4200kg. Second one did 7900kg. Times those numbers by 2.2 and that's how many pounds it breaks at. One US ton is 900kg while one metric ton is 1000kg
This time last year iirc they recalled a bunch of HF Jack stands for having prone to failure welds...
@@aninnymoose720 That and the teeth on them were not fully machined and were not locking.
@@astro.5oh incorrect. The scales were in kg, captioned as such, and relatively close to their 2 ton (2000kg) rating (as labeled on the box and stand) before deformation. Deformation isn't failure and the rating is for maximum weight with no deformation. In this video, it's being tested for max weight before total failure which was 4200kg (4.2 metric tons) and 7900kg (7.9 metric tons). in the second part, it was a test to see how much it'd take to completely destroy a stand which is easier to label in tons as 1 metric ton is equal to 1000kg, but the scale was still in kg. The first one we see captioned in tons was the black stand which reached 14500kg (14.5 metric tons) and 30000kg (30 metric tons)
Thanks for the demo. Everytime a stand has failed for me it was due to sideways/angled pressure not straight down. Usually the stands will twist if they fail.
In all fairness, the yellow one held up to more than twice it's rated capacity. (4218kg = 4.6 Tons)
Also surprises the collapsible one held up better.
It also takes up less space in your car's trunk (boot) or tool stand since it folds.... I was very impressed in how much stronger the cheaper stand was!!!

Edit: welp, seem like i miss alot of thing.
Wow....I have both styles. I have switched to the yellow one over the last 25, for the 4 legs over three and the top and bottom contact points don't roll over. Plus the more height adjustment spots. The folding black 3 leg was impressive, it has flat base on the bottom, and the folding legs would make it great to leave in the car. I found that on some of my older 4 legs, the box around the wedge finger, on top, had weak welds,and the box popped out. Which happens to be exactly opposite to where the lever pin passes thru the frame, and the hole elongated. I'll be reinforcing that point ASAP. Glad I watched this, on a whim!
Both are up to the job of holding what they say they will but I'd rather have the yellow in the garage with its 4 legs which gives more stability. The folding one would be great to have in your trunk if something happens on/ off road.
I've done lots of work with the folding ones and no issues
It's very stable
I am surprised that the yellow one does not have a pin option as well for extra safety.
It would sure make me feel safer since the latching mechanism is somewhat out of view.
I think this isn't necessary, if the jack is under load, the full weight lasts on the latch, so you have to lift the whole weight a centimeter with this small lever, wich definately would require some pretty superhuman strength.
@@elrondmcbong467 I have used the yellow version many times, and many times simply knowing did not make me feel safe.
mine has
Many of better ones have pin option.
I have a pair of the ones like the yellow one. Mine have a solid steel pin that slides in to aid the ratchet mechanism. They cost like $60 for the pair.
I want the guy with the RESTORATION UA-cam channel to fix the car jack back to pristine perfection... now that would be a challenge
I didn't see a jack, only jack stands.
Both stands exhibit small, correctable flaws. The yellow stand has an obvious weakness where the pin passes through the frame. Could easily be improved by reinforcing the holes. The black stand looks really good, however the wings fold early. In a few, very specific, cases this might allow the load to slide off the stand before breaking weight is achieved. Again, could easily be improved. Overall, though, both are excellent performers. I'm not overly fond of the ratchet design but the base is a more substantial four leg configuration (against the three of the black stand). For stability reasons I would probably choose the yellow stand.
Three legs are not as 'unstable' as four. A three legged table never wobbles.
@@Garethprice1979 In terms of wobble, yes. However, for legs which are the same distance from the (vertical) center line (at the base), a 4 leg design is inherently more stable in terms of tipping. That's why I used the term 'stability' rather than 'wobble'. I didn't elaborate because I thought it was obvious enough.
The titanic could have easily been improved by reinforcing the holes too. Ha. That old iron got as brittle as an egg shell when cold. I have the ratchet stands. Good to see they over exceeded there specs too
@@Garethprice1979 True, but if it's tilted one leg could see a much higher loading than the others. With the welded 'skirt' of the yellow stand, such an imbalance is partially distributed throughout all legs.
The companies that make these likely create a weak point so that if it fails, it fails predictably and safely under the tolerances they design it for. I’m not an engineer, but it makes sense to me.
Both jack stands supported more than their weight specifications on the press....both have two tons metric = 4,400 pounds load limits. Yellow one held 4.2 metric tons = 9,260 pounds. Difference in price is difference in stability and ease of use. Personal preference...no winner.
I guess it is measuring in kg, and being in america, I had to use google to convert it for me 9000kg=9.9us ton.
Finally a hydraulic press video worth watching! Thanks
that rickety looking black one was surprisingly strong
This was best case scenario for it, perfect vertical loading.
I have four of the ratchet axle stands excellent and stable . no worries when working with them supporting my Citroen C5 saloon car . I continue to leave my 3 ton trolley jack in place just for peace of mind .
I had to share this on Facebook, and in that statement I made on Facebook I said I'm looking to buy four of these $15 versions, as I am absolutely stunned and amazed beyond words how strong they are. This is one of the most fascinating and shocking in a wonderful way videos I've ever seen. I also figured out how to do a design improvement on the jackstand that was telescoping? The yellow one? By welding a ring support around that hole where the adjustment pin goes into I bet would double the strength of that whole jackstand. Would love to see someone who knows how to weld do that and then test it to see how much it would take. I'm thinking it would be at least as much as the black folding jack stand, if not a lot more.
The cheap CHINA METAL would fold up ,
With the ring in place anyway!
BUT IT WOULD
BE STRONGER!
I trust my life to the yellow type of jack.
I only lift 1/2 of a 3000 pound vehicle.
So only 750 pounds on each jack.
Thank you for easing my mind about their safety
It would be nice to have a summary at the end showing each product tested and its load before failure.
Did you watch the video? It clearly showed for each one the weight it failed at…write it down!
@@bigtuna9529 Good channels provide a summary table. Watch the Farm Project to see how it is done right.
Cool video - The less expensive pin style proved to be much stronger. I'll keep that in mind when I am shopping for new jack stands.
Both did better than I’d think!!
Nice to see! I have the collapsible type rated at the same 2 ton per stand.
It must be fun to have a press like that to do fun things with, such as this!
It would have been more informative to take them to max rated load and see if any deformation occurred. Then, increase loads by 500 lbs until the jack started to fail.
This.
Then, show where and how each could be reinforced to withstand greater loads. Yellow set would benefit from reinforcing the split pin with a solid pin, and added frame washers at the hole for the height adjuster.
Sounds like a video idea for "project farm"
That guy does some of the most thought out test on utube
I'd be interest to see how these compare with a Weber / AC Hydraulic axle stand with a locking screw thread. This type of axle stand are much safer and allow you set each stand at an exact height - to the millimetre if required.
Glad to know these will work just fine, so long as I don't try to put a train on them. Haha.
I would take those jacks back to the store, "I don't know what happened, I left my truck up on the jacks overnight and when I came out in the morning there they were!"
It would be interesting to compare the results with double-locking jack stands.
I've had the cheap ones for over 20 years and they're still good
Never cheap out on Jack stands. Had a friend who was almost crushed to death under his truck in high-school because a jack got kicked out and the teeth on his cheap jack stand sheered right off.
Lucky his dad was there to get it off of him.
Using jack stands properly is important too.
They are made to support the static vehicle weight. Impulse loadings from a falling vehicle are exponentially higher.
You must be lying because these $15 Jack stands out did the $25 ones 😂
@@NoizyBearBearOfficial you ever see those recalled harbor freight Jack stands?
Always use two stands and leave jack in place as well and block off back or front tires
There is another model which combines those two designs. Yellow one with a pin. I bet it would perform as well as the other one. Also, you guys need to provide a summary of the forces each was able to take at the end of the video.
Yeah that part messed me up quite a bit. Pretty sure that's expected too so arguably choosing to not include that information does not inspire confidence
Dude, that locking pin on the black stand was not giving up 🤣
I load the stands but always leave the jack somewhere out of the way as a backup. Still, I was surprised at the outcome.
I do the same. Place the jack stands, load them, then leave the hydraulic floor jack in position as a back up and place timber blocks as well. If I'm raising the front of the vehicle, the rear wheels are chocked and the e-brake is set. The rear of the vehicle, front wheels are chocked. I never use the ratchet type of jack stands, only the fixed design.
Always put the wheel under the car as a second line of defence .
Never rely on the jacking device.
@@TheBuccy i do the same! i will put car up on jack stands, have the jack raised the frame height with just a tiny tiny amount pressing the frame just to keep it in place and then ill put one or both wheels under where the frame would land on them if everything were to fail or an earthquake or something
Zajebisty test więcej takich 👍
Made in Poland 😊that is why so good quality
I used to have a pair exactly like the black ones and never trusted them, so i bought a pair exactly like the yellow ones. Same weight and same allen screw set up for the lock, thinking they were stronger. Both were pretty impressive for the price, but wow was I wrong about the black ones.
It would all depend on the brand and the thickness/reinforcing of the metal where the load is applied.
Tube around the pin holes for the black one, hole around the pivot for the yellow one.
I have a pair of non-folding jack stands for almost 40 years. USA made. It is even more tougher than the folding black ones shown on the video
Considering that a full size pickup has a curb weight of about 5,600 lbs and a full size car weighs in at under 4,000 lbs, either jack is easily capable of supporting the weight of the vehicle. Especially considering it would be distributed between 4 jack stands.
I have similar black ones (red base with black post) but outer post only goes down halfway, and legs are joined at ground level with welded on flat bar, and i also have similar to yellow ones (mine are blue with black post).
The black 3 leg type are fine a lot of the time, but as others mention, especially if vehicle up on 2 or 4 of them, are not very stable, compared to using the yellow 4 leg type.(and feel sure my ones would give in much sooner on your press, (also like yours, the tops flattened really easily when first heavy loaded)
As both exceed load ratings, i prefer the more stable type, used up to sensible loads, and so recently got a pair of the 10 ton ones as well (blue base yellow post), but may add some reinforcing to the smaller set, now i have seen what gives way first. Good video. Would be interesting to see how some heavier rated ones preform as well.

I'm from Australia so I just wish I could buy any jack stand for $15-25. The yellow one would cost me just under $100 here and would require me to earn over $200 before taxes simply to buy one.
Surprised those sloppy rivets held up on the second jack.
If only news was this real of data. Thank you!
They both took it like a champ!👍
That second Jack was far better than i expected
‘What happened to your legs LT Dan?’
‘I used Harbor Freight jack stands.’
It's interesting to see the ratchet type fail that way. I have a set of 3 ton ratchet ones I use at least weekly. I usually back them up with the twist head style ones as well. I think this video shows you where the failure point will likely be. I'm going to start inspecting the holes the pin goes through for signs of expansion whenever I use them.
One thing I want to point out though. In these tests, the load is suspended from above. It presses, but does not sit on the stand. If your car breaks one of these stands, it won't be the same. As soon as a part fails and gives way on the press, the pressure releases until the press can move down to where the stand is now, and the rate of failure is slow. Not so with a car. Gravity will make the result very different.

@@slappomatthew dude, who's lifting that much weight with these things? Anyone who's truck is that heavy isn't using jack stands. These jack stands are literally only lifting the front or back half of the vehicle they're under, and for that purpose they're pretty perfect.
Bello vedere che lo stelo cede prima ma la struttura resiste il triplo😍👏🏻👏🏻
The VERY BEST way to support a vehicle in my opinion is to use logs. I used logs that were of varying heights, 12 to 15 inches, they were of a diameter of the same. They were NOT old decaying logs either. My neighbor always had fresh cut logs he would eventually cut up and burn. I would borrow some until I found some that I kept from a tree that had been cut down locally. The price was GREAT, free, and they're better than any jack stands. IF, you buy a set, get some for a truck to use on your car, OR, the most heavy duty you can find if using on a truck. The money spent is worth the life you save.
Looks like either will do a good job of keeping you from dying by being crushed by the car you're working on. I like those folding ones - space saving.
I thought it would be the other way around. nice to know thanks great video 👍
Well little all mighty took that bigger yellow one right to school. Thank you sir for this. Well noted !!
A LOT of car jackstands and floor jacks sold at retail are all manufactured by a handful of factories in China. They are then painted according to the customer. So the only difference between dozens of different brands is the color, stickers, and warranty.
What happened with the 3-ton and six ton stands was that the manufacturing production equipment was worn out and some stands failed the load test. Harbor freight recalled them a while back. Now, AutoZone and Walmart are issuing a safety recall on the much more widespread 2-ton stands that are used by most car DIYers.

"My wife sat down in the car while I was changing the oil."
That was so beautiful in a demented sort of way.

I really hope you took them back to the store with the original packaging, ask politely if they are supposed to do this after holding up my Honda Jazz?
Nicely shown… I don’t know why I would subject a ten thousand plus load to a single unit , but that most likely his would most likely be shared between two stands and therefore hold up to the average working mans project. Again thanks for the Enlightenment. Awesome on this math!
