That jack has a safety overpressure relief device calibrated to release and maintain pressure at about 380 tons. The 500 tons was the cylinder bottoming out. Most decent jacks of 25 tons or better have a similar safety device. Took it like a champ.
@@jeepsblackpowderandlights4305 actually 50k tons would be enough to put you into Superdreadnaught range, and only two ships have been in that weight class ever since WW2 ended in 1945.
I don’t know what’s more impressive. Spending thousands$ on that bottle jack for testing, or how easily he managed to lift that roughly 100kg/220lbs out of the box.
These type bottle-jacks are extremely reliable, and by the very nature of their construction, they tend to be at least 3 times stronger than design specs indicate, but as they are cheap to manufacture, so they can play with the actual jack sizes and labels, for marketing strategy, product diversity and manipulation of prices, and the added bonus is, whatever the rating, it comes with tons and tons of safety margins built in already. Nice product, almost no after-sales problems.
The pressure is getting to the jacks Too much pressure jack? No pressure jack Increase the pressure Pressure them to pay up Exert pressure Too many people putting others under pressure Can you handle the pressure? No pressure Increase the pressure on the killer Hahaha........😓😞😣😱😤😮💨🤐 Dangit this is gonna make me look like an idiot We gonna edit all of this out
😅Totally Blown away by this experiment, as i've used mechanical Jack's that are rated @ 250/350 & 500 tons pulling & pushing individual units that were 75% completed units that are being stacked/Fit onto a Navy Battleship in Pascagoula, Mississippi & to see a Hydraulic jack rated for 100 tons survive a Destructive Test after basically withstanding 400 times more pressure than it's rating & still operational afterwards !! Just WOW is all I can say !! I personally have seen a 250 Ton mechanical jack Explode/Shatter into thousands of pieces while pulling Four 3" thick lugs/Plate Dawgs that were joined with "Sub Arc" 100% welds & we were all VERY Blessed by GOD above because we all were atleast 200 yards away returning from our first break !!! It sounded & looked like a Bomb had gone off !!!
I wonder if the valve in the 2 ton orange jack is the same as in the 100 ton orange jack? I would like to see the 100 ton valve "after" autopsy. Any real damage or just the safety letting go and resetting? I have a pair of 30ton jacks and those are about all I can lift and carry. Was that 66 kilos marked on the 100 ton shipping crate? Now, who has a need for a 100 ton jack? Thats about 50 cars.
