That old jack...it could have been passed down through generation after generation, it was on its journey to fulfill its destiny when fate brought it to CHP and that, as the records show, was the end of the line. Life cut short for our entertainment. I am not sure how I feel about that.
By far my favorite test! This is an actual usable test for the safety of others. Thank you so much! (From a guy that has been under a lot of vehicles with many different types of jacks.)
No surprise at all that the old one did way better than any of the others, but if they had the contact surface loaded as it was designed, it would have held on way longer than it did.

I had a mechanical jack for years from on old Datsun. I used that for years. I didn't realize how it worked until you broke it and it looks like a differential inside with a ring and pinion gear set. Thanks for educating me.
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.
Excellent testing , the old stuff is definitely amazing I’m shocked at how good the threads on the plastic one were , if the body was thicker it would probably have done better
I feel like the old one would have done better if they'd shaved the top flat so that the pressure would have stayed even from the start. Having one side break off introduced some shear that caused early failure IMO, and yeah. the plastic one surprised me. I figured it'd be right down there with the scissor jack.
@@hdj81Vlimited Any idea what the model number is? I'd guess it was glass reinforced nylon - same stuff power tool makers use. Has similar strength to cast aluminum.
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.
@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.

In an actual overload situation that plastic jack is by far the most dangerous since the housing is the first part to fail allowing the load to suddenly fall - That would kill.
@@Senkino5o I don't know. Those rhomboid ones are horrible and pathetic.. In a real situation definitely dangerous. Too close to failing under the weight of a normal car.
@@Lucien86 Those rhombic jacks are also depressingly common. There's also another screw type jack that comes with some cars. It has a vertical screw a bit like a budget version of the mechanical jack. As simple as it is it's still better than the rhombic ones.

I have a 2 ton hydraulic jack on wheels like that orange one that I bought at autozone for $20 20 years ago when I was 18 years old. I used it for every oil change and brake job I did on my car and some of my friend's cars up until about 3 years ago when I replaced it. it still works and I keep it around as a backup in case it's needed. I also used that thing up on blocks to lift the front end of a ford F-250 once to get it up on stands. No doubt it would have done better than the one in this video. But the one in this video reminds me of the one I originally bought trying to replace my old jack about 10 years ago. That one had the hydraulics fail on it the 3rd time I used it trying to lift up my honda I had at the time and the store wouldn't take it back.
Very interesting. Knew a scissor jack wouldn't be very strong, but looks like they're almost a waste of money. Same with the plastic one. Thanks for the video.
If you'd used these much before you would know that there is no 2ton rated scissor jack, those things are good for lifting up an axle on a passenger car and nothing more.
@@prakhargahlot9373 you must not be lifting very high then, cause the point where it was in the video is how far it would be extended before it even makes contact on a lot of vehicles 🤦♂️
Of course that's going to make a difference turns out if you asked for a little physics you will find using a length of something as a support prop will support a much higher weight as opposed to using it as a lever support
Given that the cheapest jack that was made out of plastic preformed that well was impressive. I'd probably go with the 60$ 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.

I am honestly surprised at the performance of the roller jack. I thought it would be for sure the best one. Well, I guess it's time to go out and buy one of those little mechanical jacks. That did surprisingly well, just shy of 14 times the maximum rated load.
That roll jack was a very sorry excuse for a roll jack if you ask me, it honestly behaves like it was made in china. My $20 American made roll jack has served me well for years now.
Seriously impressed by that red mechanical jack holding up to 7 times the rated value. The scissor jack and trolley should be investigated for not meeting the rated value, they were terrible.
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.
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).
Now wait a minute, the old Jack looks older than me, and I was born in 1959. Of course, it was also in better shape than I am too. lol. It did amazing. The mechanical jack also did better than I would have guessed that it would. Great test.
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!
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
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.
the best part about the bottle jacks is even if they fail they still give you that little bit of room, which doesn't matter much if you have tires but can still help, especially without tires on. Might save your life.
When changing tyres/working with the wheel off slide the wheel under the body of the car near where your working, if everything fails the car will sit on it and give you some clearance to get out/breath.
@@paidwitness797 Ye I am aware of that. I was just thinking about if for some reason you had a wheel off and didn't have a wheel and was under the car. it would be an odd situation to get into but I have seen it lol
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.
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.
Well if you need to do that, side of road, make sure you don't put any of your body extremities under the vehicle. Also watch out for those mirrors, if vehicle drops the wing mirror can hit you in the head!
I don’t think the green jack was properly cranked. You won’t get the proper leverage with the crossbar extension. You had to feed the curved bar into the loop further and crank it directly almost like a crowbar.
Taka propozycja: Może zmienić tło, na przykład z czystego białego na białe w jakieś paski. Fajnie byłoby widać jak dana rzecz się wygina. Ewentualnie z miarką 😊
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.
Ну вообще то это должно быть подсудным делом, если написано 2т а домкрат ломается на 1600. И сажать производителей надо раньше, чем кого то раздавит машиной которую им поднимут.
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. Lotta possible dangers in real world applications, but yes it was still impressive for a lab rat test.
@@Cheepchipsable Well maybe you would, have at it. My comment didn't have anything to do with vehicle size, I was referring to imperfections in ground and environment. 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. You go on with it, I'll stick to something a little more durable.
I'll take the plastic one over the last one any day. I was thinking that garage jack would be the winner ( the one most of us are guilty of using with no jack stand) but it was the worst one!
@@donsmith9478 yes, but they're poorly designed for it even then. A stiff wind can shift the vehicle enough to make it tip/collapse. I had it happen with a scissor jack when I changed a tire on the side of a road. I carry a floor jack now because of that.
It's frightening to see how little that trolley jack took for it to fail, I've been using them for years...😮 I think I'll invest in a decent hydraulic bottle jack from now on.
to be fair its rated for 2 tons (2000lbs or 907kg) ... he stressed it and logged it failing at 1709kg or 3767 lbs, realistically it was moving and bending before that but it handled more than 3 tons for a 2 ton jack. as long as you aren't dropping another car on the car you already have lifted you should be fine.
@@Crazy49er 2 tons is actually 2 metric tonnes or 4000kg or 8818lbs. He logged its fail at 1709kg or only 43% of its nominal capacity. Disgraceful. I have one of those cheap trolley jacks but it only ever use it to jack up a motorcyle while I get some blocks under it. I'd never use it on a car.
@@MrPoopnoddy OMG how are Americans failing this ship called conversion without a dingy to float on. 2 metric tons is just 2000kg. Metric just stands for the scale so that you do not confuse it with imperial ton which is about 2030kg or US ton. Thus 2 Metric tons is 2000kg and not the 4000kg you typed.
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.
@@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.
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 …,
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)
@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.
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.
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 😆

I am honestly surprised at the performance of the roller jack. I thought it would be for sure the best one. Well, I guess it's time to go out and buy one of those little mechanical jacks. That did surprisingly well, just shy of 14 times the maximum rated load.
That roll jack was a very sorry excuse for a roll jack if you ask me, it honestly behaves like it was made in china. My $20 American made roll jack has served me well for years now.
just buy an actually decent rolling jack that thing was a piece of sh*t
All of these were Russian pieces of sh*t
He's right it is a piece of shit mine broke second time using it pissed me off tire was flat and I was tryna get to work
Made out of bud light cans
Nice! You actually tested these fairly accurately by using the jack first then stressing them from there.
Seriously impressed by that red mechanical jack holding up to 7 times the rated value.
The scissor jack and trolley should be investigated for not meeting the rated value, they were terrible.
Thank-you Sir, good stuff.
An overall tabulation of the results would have been appreciated.
I want 4 of those 1970 jacks lol
Verry good guys we watch your channel a lot well when we are not build something or blowing it up thanks 👍🏼
Love this videos! 💚
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.
Shocking about the plastic jack! And praying for the cool old jack. 🙏
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).
Now wait a minute, the old Jack looks older than me, and I was born in 1959. Of course, it was also in better shape than I am too. lol. It did amazing. The mechanical jack also did better than I would have guessed that it would. Great test.
очень полезное видео я рад что оно мне попалось наглядное пособие молодец
I think a bit of grease on the threads of the green scissor jack would have helped. The threads seemed dry.
When I was scrolling I though the thumbnail was of bongs being crushed
That 70’s jack held up well!
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!
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
Excellent Job!
Nice to know you are taking pictures and waiting for them to develop......
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.
the best part about the bottle jacks is even if they fail they still give you that little bit of room, which doesn't matter much if you have tires but can still help, especially without tires on. Might save your life.
When changing tyres/working with the wheel off slide the wheel under the body of the car near where your working, if everything fails the car will sit on it and give you some clearance to get out/breath.
@@paidwitness797 Ye I am aware of that. I was just thinking about if for some reason you had a wheel off and didn't have a wheel and was under the car. it would be an odd situation to get into but I have seen it lol
@@paidwitness797 Comments like this save lives, hell when I was told this it saved mine less than a year later.
@@lokian1174 It was what i was thinking when i typed it, if it gets just 1 person out of trouble it was a worthy post!
Impressive how strong the hydraulic jack (bottle), the old 70's iron jack and especially the mechanic jack that suports more than 16 tons...
The video was king.😊
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.
The old 1970 jack is now considered a rare piece of art after this debacle.
Домкрат СССР
my dad sells antiques and i can assure u there are plenty left
Thank you Crazy Hydraulic Press for effectively testing vehicles jacks that many of us home mechanics foolishly use trusting on the label.
I miss the original jack, which is given to the car.... Great results, Thanks. I mostly use the jack on wheel.... :-)
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.
Pretty sure this guy has never changed a flat tire before
Well if you need to do that, side of road, make sure you don't put any of your body extremities under the vehicle. Also watch out for those mirrors, if vehicle drops the wing mirror can hit you in the head!
He certainly didn't know how to crank on a scissor jack or the others with a loop hole in the raise and lower arm~!!
I gotta find one of those mechanical jacks. Looks like a good one to carry in the car. Far better than the rombic junk.
Excellent consumer advice - ditching the scissor jack immediately.
I don’t think the green jack was properly cranked. You won’t get the proper leverage with the crossbar extension. You had to feed the curved bar into the loop further and crank it directly almost like a crowbar.
Sounded like it needed to be lubed, too.
it hurts to see you destroyed the vintage jack😢
Fantastic test, well done
Taka propozycja:
Może zmienić tło, na przykład z czystego białego na białe w jakieś paski.
Fajnie byłoby widać jak dana rzecz się wygina.
Ewentualnie z miarką 😊
"do not try it at home" everyone has a 150 ton hydraulic press on their kitchen counter...
This guy is not afraid to push that hydraulic press to the point of making it pretty dangerous. Not like other press channels
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.
Super interesting thank you 😊
Ну вообще то это должно быть подсудным делом, если написано 2т а домкрат ломается на 1600.
И сажать производителей надо раньше, чем кого то раздавит машиной которую им поднимут.
The jack is meant to jack something up not hold it that's why you use metal Holders witch some in my shop can hold 25 tons
A couple of real shockers for me. Turns out, a plastic jack rated for two tons is not as crazy as it sounds!
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. Lotta possible dangers in real world applications, but yes it was still impressive for a lab rat test.
@@acesup5845 Obviously it depends on the vehicle you are lifting. You wouldn't use it on an F150 but would on a Miata
@@Cheepchipsable Well maybe you would, have at it. My comment didn't have anything to do with vehicle size, I was referring to imperfections in ground and environment. 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. You go on with it, I'll stick to something a little more durable.
@@Cheepchipsable but it wouldn't even fit under a miata.
@@Cheepchipsablehopefully you wouldn't OWN an F150
Need to try that scissor jack all the way up the cheap green one
That mechanical jack was impressive!
Pretty impressed with the plastic jack. I would not trust it unless it was brand new tho
I'll take the plastic one over the last one any day. I was thinking that garage jack would be the winner ( the one most of us are guilty of using with no jack stand) but it was the worst one!
NEVER use a cheap floor jack. They'll get you killed. And always use jack stands regardless of the jack you use.
The small floor jack is intended to be used in the same manner as the rhombic - lifting one corner at a time only.
@@donsmith9478 yes, but they're poorly designed for it even then. A stiff wind can shift the vehicle enough to make it tip/collapse. I had it happen with a scissor jack when I changed a tire on the side of a road. I carry a floor jack now because of that.
Verry interesting. I love the idea to stress-test old vs new stuff.
I think old stuff has higher quality then new. .. Like humans ;)
Good one~!!!
I'm going to be scouting out old farmers sheds for an old 1970s jack now!
It's frightening to see how little that trolley jack took for it to fail, I've been using them for years...😮
I think I'll invest in a decent hydraulic bottle jack from now on.
to be fair its rated for 2 tons (2000lbs or 907kg) ... he stressed it and logged it failing at 1709kg or 3767 lbs, realistically it was moving and bending before that but it handled more than 3 tons for a 2 ton jack. as long as you aren't dropping another car on the car you already have lifted you should be fine.
@@Crazy49er 2 metric tons are 2000 kg, or 4409,25 lbs if you prefer retarded units 😬
@@Crazy49er 2 tons is actually 2 metric tonnes or 4000kg or 8818lbs. He logged its fail at 1709kg or only 43% of its nominal capacity. Disgraceful. I have one of those cheap trolley jacks but it only ever use it to jack up a motorcyle while I get some blocks under it. I'd never use it on a car.
The problem with a bottle jack is that they don't work on any car. Only suvs and trucks
@@MrPoopnoddy OMG how are Americans failing this ship called conversion without a dingy to float on. 2 metric tons is just 2000kg. Metric just stands for the scale so that you do not confuse it with imperial ton which is about 2030kg or US ton. Thus 2 Metric tons is 2000kg and not the 4000kg you typed.
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.
This channel is great.
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 …,
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.
Interesting Video - to See the physics and Limits...
Super test. Thank you
RUSSIAN!

That Jack looks fermiliar 🔥😅
The old jack even after CHP is interesting piece of art.
@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.
Yes I agree with you on the rhombic jack~~I have two of them in my shop and use them for everything as the can start out very low.
My hand started getting a cramp watching you operate all those jacks...😅
I was not expecting the plastic one to last that long at all
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.
Why the hell do we like to watch this type of video so much???
12:47 I did not expect that deformation of the threads, wow, mushed!
epic backflip of the old jack hahaha
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 😆
