How a hydraulic jack works

A hydraulic jack (also called a bottle jack) is a mechanical tool that uses hydraulic fluid pressure to lift heavy objects. They are commonly used for lifting vehicles and machinery.

In this 3D animation video, we will be looking at the key internal and external components of a hydraulic jack. Understand the 2 working principles of a hydraulic jack, the law of the lever, and Pascal’s law. Finally, we will see how the mechanism inside a hydraulic jack works during operation.

Best video I've ever seen to explain the principles of Pascal, hydraulic & leverage. Bravo!

[EweKnowWho]

I can’t imagine how you could make these scripts and 3D animations any better than you have. What a great resource for learning about the workings of machines. I will definitely be watching for more of your excellent videos! 👏

Concise but detailed, illustrative, well narrated, thoroughly explained and gorgeously animated.

Top tier quality content

This video just reminds me of the importance of jack stands. Watching this video made me think back to all the times my life was in the hands of a small steel ball and how seriously the people in the quality control department take their job.... Jack stands folks, jack stands....Excellent video by the way.

Such a simple machine. I’ve always wondered about the internals. Thanks.

I just got a bottle jack for the first time, and watching this video was paramount to understand the functionality and safe operation of the bottle jack. Job well done!

I still can't imagine how you came up with this act, seriously this is the best video I have seen explaining Pascal's principle with respect to Hydraulic Jacks.

A very educational video which I think should be used in schools to teach mechanical principles. I had watched it with a friend who answered the last of my lingering questions about a topic I had never thought about beforehand.
Please make more of these meticulously crafted animations with explanations!

This is an awesome explanation for how hydraulic jacks work!

something that I'd like to add though is that at 5:22 the bigger piston of the jack doesn't just move a third of the distance of the smaller piston because it needs to conserve energy, it moves a third of the distance because physically more fluid is required to fill up the larger cross section. The law of conservation of energy is always a consequence, never a cause for something!

Wow, what a great video and explanation of how a bottle jack works. I have to repair a bottle jack on my J & S jack (company now out of business). The hint was to reverse the pressure relief valve gasket. From this video I learned the inner workings of the jack and can see how to reverse the gasket. Thanks so much.

You are an excellent educator. The tempo of your explanation, the order in which information was shared, and your choice of words made this very easy to understand.

This video is absolutely spectacular, thank you for that, I suspect it will help me in my repair of a pallet jack. I have one criticism to make. The type of screw adjust saddle on this particular build is used to extend the jack beyond the typical hydraulic limits, rather than to fine tune the height. There are some made to fine tune, but they typically have another rotator on the top to allow it to be raised while already under load, a near impossibility with this model. If nothing else, the screw top goes that little way toward making sure someone is not using blocks on the top to get a bit more height in an unsafe manner.

This is the best explanation I have seen on this topic.

I just bought a motorcycle lift with a hydraulic ram that had a small fluid leak. This video took all of the guessing out of its workings and repair. Well done and thank you very much.

[edwardsimmons]

I really enjoyed this explanation. The details are spot on and explain how fluid pressure multiplication is achieved.

[andrewlim]

Very clear and explains everything I need to know. Looking forward to more videos from Deconstructed. Kudos.

Thanks for this flawless showcase, so simply built yet so effective

[palco]

Most of us have a good idea of how the bottle jack works (... as does the floor jack) but these videos shows the details and that's always interesting.

[rachidlamzougui]

This a great explanation of the workings of the hydraulic bottle jack. I sea perfectly the inside components and workings of this tool. Thank you very much

[masflow]

This video has made me subscribe to your channel. Not only did you explain how it works but also described the different principles behind it. Awesome!
