What most people call plastic is really complicated compared to metals. It's a lot of variation in polymers structure. The wires made of these polymers can easily be orders of magnitude stronger then metals by weight and couple of times stronger by volume. The difficulty is to arrange the polymers to match the load when you have complex shapes.

I have a 2 ton hydraulic jack on wheels like that orange one that I bought at autozone for $20 20 years ago when I was 18 years old. I used it for every oil change and brake job I did on my car and some of my friend's cars up until about 3 years ago when I replaced it. it still works and I keep it around as a backup in case it's needed. I also used that thing up on blocks to lift the front end of a ford F-250 once to get it up on stands. No doubt it would have done better than the one in this video. But the one in this video reminds me of the one I originally bought trying to replace my old jack about 10 years ago. That one had the hydraulics fail on it the 3rd time I used it trying to lift up my honda I had at the time and the store wouldn't take it back.

It would have been even less in its lowest configuration due to the geometry of the arms. Impressed with the plastic jack.

@daveyjones I fully agree with you. It's all about mechanical advantage. Obviously a mechanical screw jack potentially will produce the highest load. When he tested the green rhombic jack he stopped halfway through the test then gave up easily. It would have produced more load with more effort. Plus it will produce greater load, the higher it's extended ! The law of the lever. Bear in mind almost every car has this type supplied for flat tyre replacement and only needs to provide about a quarter of the vehicle load- perfectly capable for any vehicle they're designed for.

The only issue here with the testing is the thrombic ha k and trolley jack were tested at their weakest lifted height. Both jack gain exponentially higher resistance the higher the jack is lifted. Personally i prefer lift with a trolley high enough to pop it on an axle stand then switch to a bottle jack.

@@cloric1 Complete rubbish. It's nothing to do with "spread of weight", whatever you mean by that. Neither jack was able to support two a two ton load. All the others did it with a very considerable safety margin. It's entirely irrelevant whether they were tested at their weakest configuration or not. If they are rated to support two tons, without qualification, then they must do so, with a safety margin, in all stages of lift. If what you mean is that you can use one of those jacks to life the corner of a two ton vehicle to change a wheel then, maybe. But that's not what a load rating means. Perhaps you ought to ask yourself, if all the other jacks managed to support a two ton load with ease, then they are clearly a lot stronger and a lot safer. This is pathetic. If they cannot support 2 tons through their entire range, then they should be rated at what they can support, which on this evidence is less than 1 ton with virtually no safety margin.

Make sure you use jack stands under anything you plan on climbing under. And never use cement blocks, if anything use blocks of wood like 4x4’s or 6x6’s.
Or at the very least, make a block sit with the holes vertical! That's two sides and three webs holding the weight up, but only the three webs like on it's side. I just cringe when I see them sideways like that!!! There's more than one reason they sit in a foundation the way they are built. Plus making sure there aren't any stress points on concrete helps a lot, like a wood block under and above it. But yeah, still a very bad idea.
Squished like a BUG
@rukamukus . . . it's good that you pointed out about not using cement blocks. While the blocks can be heavy, dropping them from a height of a meter or so onto pavement can result with them to fracture. Yet, YT has videos where people try to impress viewers on the power of a firearm with a bullet breaking a cement block apart; as the same can be done with a carpenter's hammer.

Given that the cheapest jack that was made out of plastic preformed that well was impressive. I'd probably go with the 60$ mechanical jack. Really tough.
What most people call plastic is really complicated compared to metals. It's a lot of variation in polymers structure. The wires made of these polymers can easily be orders of magnitude stronger then metals by weight and couple of times stronger by volume. The difficulty is to arrange the polymers to match the load when you have complex shapes.
This a copy from the old toyota jacks.

The rhombic jack might bear more weight if it's extended more; the leverage might be shifted to different stress points.
If you'd used these much before you would know that there is no 2ton rated scissor jack, those things are good for lifting up an axle on a passenger car and nothing more.
Yes but in the actual cases where it is used, its extended even less

I have a 2 ton hydraulic jack on wheels like that orange one that I bought at autozone for $20 20 years ago when I was 18 years old. I used it for every oil change and brake job I did on my car and some of my friend's cars up until about 3 years ago when I replaced it. it still works and I keep it around as a backup in case it's needed. I also used that thing up on blocks to lift the front end of a ford F-250 once to get it up on stands. No doubt it would have done better than the one in this video. But the one in this video reminds me of the one I originally bought trying to replace my old jack about 10 years ago. That one had the hydraulics fail on it the 3rd time I used it trying to lift up my honda I had at the time and the store wouldn't take it back.
every single minute worth to watch! Thank you very much for this informative video!
Yes, not designed to support the load on the ears of the head. As soon as one ear failed, the pressure was skewed out of alignment causing the main shaft to bend. Still not bad for a 50 year old jack.

Thank-you Sir, good stuff. An overall tabulation of the results would have been appreciated.
In defense of the old jack, the wings were not ever intended to bear the weight. When they broke, the stress was no longer vertical and the jack failed quickly. Had the press been directed on the center of the jack, that thing would have probably have out lasted the press itself.
Very interesting. Knew a scissor jack wouldn't be very strong, but looks like they're almost a waste of money. Same with the plastic one. Thanks for the video.
I think a bit of grease on the threads of the green scissor jack would have helped. The threads seemed dry.
I actually felt sorry for the old jack. At least it made a cool exit. Those things are hard to find, cause nobody wants to get rid of them. Some of those manufacturers should get sued. The ultimate breaking capacity should have a safety factor of at least 2.5 to 3.0 of its rated value. The scissor jack didn't even have half of its rated capacity. It would have been even less in its lowest configuration due to the geometry of the arms. Impressed with the plastic jack.
When I realized the old jack was going to be destroyed I whimpered a bit.
Yea. E to
Nice! You actually tested these fairly accurately by using the jack first then stressing them from there.
Fantastic and useful test! Well, I guess (rather surprisingly to me) hydraulic and mechanical jacks turned out to be overall the best ones (though they all have applications and deisng purposes).
This is an awesome test. I have each of these styles of jacks. Not only seeing when they fail but how they fail will have me remembering bout this test when I reach for a jack… good stuff.
Basically, don't trust any jack made from pressed steel... it was also a little unfair on that cast iron jack in that it's designed to support an axle or a chassis rail, and not have the force transmitted onto the tops of that cradle casting. Once those broke off, it performed admirably.
I gotta find one of those mechanical jacks. Looks like a good one to carry in the car. Far better than the rombic junk.
These Ys are for preventing the screw jack from snapping not for a load! Put any material strong enough to fill the gap then tighten it hard! And the scissors jack try with the hook past the ring so the bar is one half in your both hands, then apply more force. If the bar bends put something stronger in same manner! 800 is enough for most cars tyre job!
The old 1970 jack is now considered a rare piece of art after this debacle.

I had my money on the old ratchet jack with the bottle jack in second. The one weak spot on the old jack is the cast iron “wings”. I was surprised that the floor jack couldn’t even make it’s stated lift weight let alone take 4 tons, which is the minimum safety margin for a lifting machine.
@daveyjones I fully agree with you. It's all about mechanical advantage. Obviously a mechanical screw jack potentially will produce the highest load. When he tested the green rhombic jack he stopped halfway through the test then gave up easily. It would have produced more load with more effort. Plus it will produce greater load, the higher it's extended ! The law of the lever. Bear in mind almost every car has this type supplied for flat tyre replacement and only needs to provide about a quarter of the vehicle load- perfectly capable for any vehicle they're designed for.
The 1970s jack I think would have went further before breaking only because the press couldn’t press directly down in the center like the frame if a car would and instead broke the ears off it.
that fat red one is a wormgear jack. i have two different ones and they never stop amazing me how much they really can take. basically as long as you manage to turn the drive shaft it will manage to lift

True enough but only under ideal conditions, table is flat and level, press comes down slowly and straight. Can't say I'd wanna do a road side tire change though, every car going by shakes yours and the jack gets side pressure, uneven ground.

Anybody who has changed a tire roadside knows that when another car passes by you the vehicle shakes, now compound that with an uneven ground and even a Miata could conceivably be heavy enough to cause jack failure. Similar to a crane or forklift with a load being lifted straight up they can do a bunch of weight measured in tons but put a little side strain and they collapse under pressures measured in thousands.

The only issue here with the testing is the thrombic ha k and trolley jack were tested at their weakest lifted height. Both jack gain exponentially higher resistance the higher the jack is lifted. Personally i prefer lift with a trolley high enough to pop it on an axle stand then switch to a bottle jack.
Doesn't matter though. If they are rated for 2 tons then they should be able to lift 2 tons through their entire range of motion.
That's exactly where they should be tested. Safety matters.
@@TheEulerID spread of weight means neither jack face that weight at that height if used correct.
@@Tymopta thats not how their works though, The weight is multiplied by height and the strength is increased by the angle created by that height. You’re not lifting 2t when jacking a car up on one side, weight is transferred.
@@cloric1 Complete rubbish. It's nothing to do with "spread of weight", whatever you mean by that. Neither jack was able to support two a two ton load. All the others did it with a very considerable safety margin. It's entirely irrelevant whether they were tested at their weakest configuration or not. If they are rated to support two tons, without qualification, then they must do so, with a safety margin, in all stages of lift. If what you mean is that you can use one of those jacks to life the corner of a two ton vehicle to change a wheel then, maybe. But that's not what a load rating means. Perhaps you ought to ask yourself, if all the other jacks managed to support a two ton load with ease, then they are clearly a lot stronger and a lot safer. This is pathetic. If they cannot support 2 tons through their entire range, then they should be rated at what they can support, which on this evidence is less than 1 ton with virtually no safety margin.
scissor jacks was/are underrated. 20v impact and proper socket head/weld-adapt will lift a car or truck easily, and quicker than the rest, with less sweat, on a sweaty day. Throw away the death wand shepherds hook, and weld a bolt head on the end.
How has nobody noticed that a single ton is 2,000 pounds. So a 2 ton rating would be 4,000 pounds.
It's pressing in kilograms fool.
An Imperial Ton is 2240 lbs
This video doesn't mention pounds, why did you?
It was a bit misleading . 1000 kg is one metric ton.
In metric measurement the 'ton' is spelt 'tonne'; 1000kg. When will America catch up with the civilised world..?
Ох ля, вот просто сижу и с большим интересом смотрю, да какой же нагрузки ты ромбическую механику на винте выкрутишь))) Под конец прям больно, но почти тонна, красава)
Было смешно.
My grandfather had three or four of those old screw house, jacks… When he used to work at the Roundhouse at the railroad station, he got them from work …,
Cast iron is brittle, so it's not surprising that the forks broke. Or that the end failure happened like it did. The impressive part of all of this is all of the failure types and places. This was neat!
My first thought was that the forks were never meant to do the lifting and they should have put in a block so the load ran down the centre as intended.
RUSSIAN!
Your videos are pretty cool whats the max pressure or force of your press?
Nice to know you are taking pictures and waiting for them to develop......
4:30 Man, I was waiting for that thing to let go and see some bloody knuckles. Had my safety goggles on and backed away from the screen.
I noticed one major flaw in your tests. 1 ton is 2, 204 pounds. Each jack should have been rated to approximately 4,400 pounds. Some of those barely handled a half ton! Would love to have seen the initial tests go up to 2 tons before the stress test.
He's in kg on the scale not lbs. He was hitting 2 tons
I still have the old jack, a little rusty on the outside but it still works. My grandfather was a war veteran, maybe he used to be a combat vehicle mechanic or something, or he maybe stole from the battalion garage. Idk 😆
5:34. I use a long thick flathead screwdriver with those when I can. Makes short work when short on time. 😉
Why the hell do we like to watch this type of video so much???
"Plastic Jack" Great name for a 21st Century Pirate
Putting the strain on the two fork tips of the Plastic- and Old Jack is unfair. These forks are there to prevent slipping off the load and not to pick up the load. It would have been correct to put a suitable round or square bar in the fork and put the load on the bar.
Country of manufacture would have been interesting. Both for strength and standards perspective. Also, loading some of the jacks on points of contact clearly not meant to be the primary load bearing surface was sketchy. As bad as the Rhombic jack seemed, at least it refused to lift more than it could handle.
I preferred the Old Jack . Rare,exotic and durable.
No man has the right to be an amateur in the matter of physical training. It is a shame for a man to grow old without seeing the beauty and strength of which his body is capable. That was said more than 2000 years ago and that old jack left earth very happy...
This is what happens when a bunch of car jacks bully a hydraulic jack.
Fyi, a socket and impact gun with the green jack makes for effortless up and down. Screw the metal handles. I use this jack all the time on the cars I work on in my driveway.
Need to try that scissor jack all the way up the cheap green one
That 70’s jack held up well!
The old jack even after CHP is interesting piece of art.
Would you had thermal imaging of your 'tests' ??
Wow the green one seems absolutely impractical. What is it used for?
Super test. Thank you
gotta put a big old texas speed LS in it with 2 turbos clean her up keep the patina and go nice modern LS. My dad has had his 1972 ford gran torino since it was a few years old. He held on to it til this day. ut in 2007 he found out he caught a lung Disease from the chemicals his factory had him using. He took the lawsuit money and build Project Breathless Gran torino. Frame off resto mod with a modern new at the time supercharged 5.4L Gt500 crate engine amd a modern t i6x automatic trans and everything from interior to mosher rearend is all brand new. its like having the car i grew up in but new. any issues you pull into a ford dealership.
