This is why you do not sell your valuable jack on market place. Some will make a video of it :D

Its ultimate performance has been recorded and will live on forever. Its purpose has been fulfilled in spades. That'll do pig.

Those old jacks raised the city of Chicago 🫡

Its been training it's whole life for this moment.

Interesting though, that it would still hold it up to 15 tonne, much better than the modern jacks, why is every thing made these days worse?

😂😂😂

🤣

Randy should have let the old one live it's a destroying it

1970 isn’t “old” damnit. 😂

😅

I loved it! Not just entertainment, but enlightenment.

why care and save it when you got money to go buy 100 more with your spare pocket change

I think its sacrifice can prove to future generations that the previous things are not as bad as the public thinks, so it is valuable

bro got me tearing up

I have an old jack like that. From around the early 1920's. Was moving a guys furniture and he didn't want it.

That’s what I was thinking. It really wasn’t an accurate test, but at the same time sad to see the old jack get destroyed.

Si

Well the old one was super heavy and not 15$

After those pesky ears snapped off , she took it like a man.

you need to do the MATH 2.2 KG to 1 Pound. 2000 Pounds to 1 ton. I'm thinking this math was off on the ratings. so his 2000 KG was close but not spot on it's 2000 KG is about 2.2 tons.

Schools I went to 2000 lbs was a ton not 1000

@@chuckholmes2075 the video says it's 16630 kg. Why did you need to convert it to pounds? I said the old jack is able to hold more than 10 tons and 16 tons is more than 10 tons. I didn't understand your point of wanting to correct me

@@marcgovenor8136 and all the measurements here are KG

Thanks, probably one of the more boring videos submitted with regards to hydraulic presses.

Yeah and a lawsuit waiting to happen you can't advertise a jack that lifts 2 tons and have it fail at 1.5 tons

@@garystump5680 those harbor freight jack stands tho

That is the perfect way to put it my fellow car guy!!

Shouldn't you always put a jack stand under the vehicle before getting under it. Why would you risk it on just a jack??

No doubt. I just chunked my floor jack in the dumpster!

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.

@@Canthus13 completely agree

@@Canthus13 its not plastic, its HDPE

@@hdj81Vlimited High Density Poly Ethylene is a plastic... arguing semantics makes you look like a child.

@@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.

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.

If you're in the middle of nowhere, use your spare tire (which you should always have). Lay it under the car where you will be working. :)

the scissor was used in a dangerous way

I was screaming at the screen when he was doing this!

Well he also tried lifting it higher than it can go?

@antanastonka4164 No, it could still have went much higher. I've used those type of Jack's many times and they go higher and are easy to use.

I was cringing.

Problem is, 20 years from now, the plastic jack will crumble when you go to pick it up.

@@rmr5740 Well, I wouldn't trust taking off a tire using a plastic jack. Lol. There is something to be said about steel. That said, I was simply impressed by it, still would never use it personally or buy it.

Is that like the 'old jack 70s' in the video, cos I have no idea how that worked?.

Most would be required to have a safety margin. That 2T should be "safe", not at the edge of failure.

which one?

@@regularmdfacka2118 The wheel jack. It claimed to support 2 tons and failed at .8 tons.

@@AnotherVexium Its roughly the same size as most 1350kg trolley jacks you can buy at most tool stores, just really cheaply constructed. I knew it wasn't a 2t jack its nowhere near big enough.

Yeah really it looks like a kids Tonka toy jack 🤣🤣. It's looks fake and only held half a ton that's pathetic

@@toolmanslaton4975 and what Toyota used if you know that huge car company my dad was a trainer or mechanic or some thing and they use that kind of pump jack I mean they use the huge hydraulic things to lift the entire car where you can walk under it but yeah they can hold up a big car like an SUV if used properly when I suspect is this guy didn’t use it properly instead of raising it slightly he left it all the way down much force into a port that’s not supposed to have that much force on it instead of going down through the joint where it has thicker metal and is designed to handle it

Yeah I must say he should have skipped that one.

And then some.

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.

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

@@prakhargahlot9373 So dig a hole to put it in... Same as you do for a ladder that's too long.

@@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

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.

@@georgeyoutube7580I think new jacks are all made in China and the manufactures are squeezed on cost. The plastics used here are not the carbon fibre in a Ferrari driver tub.

Thanks for that!

Mechanical jack 9Tone ( ukposts.info/have/v-deo/ipmjnWqtj6mAwIk.html ) ~9/10T steel meelting.

😢

Just to be clear, they load measurements are in kilograms, not pounds. Correct? 1 kg = 2.2 lbs.

una lástima que haya destrozado el viejo gato no merecía ese final debio ser Restaurado a su gloria original y continuar sirviendo otros 500 años mas fue triste ver como lo destruiste..!!

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

Lol

🤣🤣

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.

Sounded like it needed to be lubed, too.

Домкрат СССР

my dad sells antiques and i can assure u there are plenty left

Yea. E to

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!

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

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.

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

Good one~!!!

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~!!

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 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.

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!

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.

Было смешно.

2 tons/tonnes = 2000 kg (exactly)

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..?

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 haven't seen one like that in the U.S. either.
