500 TON HYDRAULIC PRESS VS JACKS

please do not try this at home today we will test the strength of truck Jacks all of them will have a lifting capacity of 5 tons one of the cheapest Chinese jacks with the cool name this is Sparta its cost is $25 [Music] included with it is such a folding power lever this lever looks a little flimsy idle not underload this Jack works [Music] fine to adjust the height of the pickup there's even such an unscrewing threaded part [Music] the second test subject similar in design and principle of operation is a Soviet made hydraulic [Music] jack I bought it at a flea market for less than $13 yes $13 it is half the price of the Chinese it comes complete with such an impressive power lever by the way one swing the Jack Rod is pushed to lower height compared to the Chinese one so it will be easier to lift this Jack considering that this Jack is already several decades old it is also known in what condition it is but it seems like a working one although this visually there is a lot of noticeable damage on it even on the responsible stem [Music] part and also I managed to find such a 5ton mechanical Soviet dinosaur at a flea market of course in its design and principle of operation it is radically different from the first two but nevertheless its load capacity is similar I managed to buy this jacket for $25 at the cost of a new Chinese one unfortunately I couldn't find such a Jack in my city so I had to buy it online at a flea market and I was slightly deceived unfortunately this upper screw is screwed into the middle part only by half since it has a slight Bend I try to label it a little with the help of a press but unfortunately it didn't work out for me and there's a slight thread damage on the middle threaded part but I'm sure that the damage will not affect the strength of the Jack therefore the upper threaded part of the bend together I just saw it in half since this Jack is quite High it would not fit under hydraulic press [Music] for clarity let's compare all these three jacks by the way the Chinese Jack unlike the Soviet hydraulic one has a trapeo shaped thread just like the Soviet mechanical [Music] Jack the diameter of the threaded part is almost 20 [Music] mm on the Soviet hydraulic almost 4 mm more and on the so mechanical 15 mm more I think this mechanical Jack will have a huge margin of safety let's see how different the weight of these Jacks is before the test the Chinese will weigh 3 [Music] kg the Soviet hydraulic is twice as [Music] big and the Sol mechanical Jack weighs 13 kg four times more than the Chinese today we will not simply stupidly destroy the Jacks with the hydraulic press but we would try to accurately determine their maximum load capacity and then of course everything as you like we will destroy them so the first in line is a Chinese the essence of our test is that we will not press the Jack as usual but we will press the jack on the press a very accurate strange gouge for 20 tons is installed on the press and now we will see how far these Jacks will be able to develop their nominal force of 5 tons I have installed the press in such a position that the Jacks rods are half extended the Chinese barely managed to gain an effort of 2 tons the reason is the very short lever that was included it is extremely inconvenient for this swing therefore we will have to borrow the lever from the Soviet one it's more interesting to work with this lever [Music] the effort of five tons on the Chinese was a bit difficult to develop in principle it keeps a state loaded so now it's the turn of the Soviet hydraulic [Music] jack on the Soviet Jack it was absolutely no problem to develop its nominal effort but then I noticed it does not hold its rated load but the reason it turned out to be the banel was that the bypass valve was not Twisted to the end as soon as I twisted it I made sure that the Jack perfectly hold its rated load [Music] now it's the turn of the Soviet mechanical monster [Music] well I can say that it is extremely inconvenient for them to work the fact is that here I work in a limited space on one hand I have a camera and on the other lighting and it is extremely inconvenient for me to make such wi swings [Music] and also I see that there's a little scooted and trying to jump out of form under the Press but here the reason is that there is a little crooked as I said earlier now let's move on to the next test with the help of a press through a load cell we press on the jack and see what load it will give up [Music] [Music] the chines Jack gave up underload a little more than 13 tons in principle this is a very good result it has withstood a load exceeding its normal load capacity by more than two times and apparently it died now it does not develop its efforts what kind of load will the Soviet hydraulic jack withand [Music] the Soviet Jack is guaranteed a withstand of load of 20 tons most likely it would also withstand a much larger load but unfortunately our strain gouge is designed for only 20 tons if we develop our efforts further we will simply break the strain gouge after exposure to a 20ton load the Jack is in working [Music] condition will a 20ton screw Jack withstand 20 tons withstood but with the load of just over 21 tons something specifically clicked in it and now as I promised with the help of 500 ton hydraulic press we will simply destroy all these [Music] Jacks and at the same time we would check the maximum load to their holes can withstand and what will be the nature of the destruction of the jack [Music] l [Music] [Music] the maximum load with the destruction of the body of the Chinese Jack was 110 tons [Music] yes probably under warranty it would not be accepted the Jag by the way warmed up decently during deformation and its temperature is more than 30° although the room temperature is less than [Music] 14 well now it's the turn of the Soviet hydraulic jack [Music] the Soviet Jack lost his work capacity with the load of 30 [Music] tons unfortunately he started popping out from under the Press now we would corrected and continue the experiment [Music] [Music] [Music] [Music] [Music] [Music] the maximum load at which the body of the Soviet Jack render was 170 tons [Music] and from this angle you can clearly see how the Jack housing exploded [Music] [Music] in this iron porridge you can see the thickness of the wall of the power cylinder of the [Music] Jack and this is the unscrew screw part [Music] now we will try to consider in more detail the parts of the power cylinder of the [Music] Jack this protruding piece is a fragment from the [Music] cylinder and it has a very impressive thickness compared to the thickness of the cylinders in the Chinese Jack [Music] I wonder what result the Soviet mechanical screw will show us [Music] the maximum load was 80 [Music] tons is it a lot or a little but considering that this's nominal value is 5 tons then 80 tons I think is a lot it was this one the middle threaded part that gave up she turned out to be the weakest link of this Jack in fact it is a pipe the outside and inside which is threaded and the thickness of the walls of this pipe is not so impressive it is comparable to the thickness of a coil the upper threaded part was also slightly deformed from the bottom it looks like we have a massive cast iron bed left alive but by the way you can still see that the nut is cracked in several places let's see what kind of load this massive frame reassembly the Bell will withstand [Music] [Music] the Bell collapsed at a load of 210 tons [Music] write in the comments which jack in your opinion won the test which Jack would you choose from these three personally I like the Soviet hydraulic jack the most
