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.

Fun fact o have a bottle jack in my spine but bone growth is what makes the jack rise up

[@FIRE_STORMFOX-3692]

Why is it 3 times the force over a larger area?

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

[@Five-O_Reviews]

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.

[@ChaosNe0]

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!

[@masflow7]

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!

[@Se7nDust]

I tried using a bottle jack horizontally recently, and was shocked when it didn't work...i guess my check valve is gravity seated 🤦‍♂️

[@jerrybeckner5954]

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!

[@divy1211]

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!

[@nilutpalchangmai5088]

Excellent explanation and very well articulated !👍

[@slymike21]

That was amazingly described and presented. Thank you!!

[@leopard6554]

I worked years with jacks but never knew how they worked 😕 😪 Thank you 😊

[@palco22]

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.

[@travishall67]

[@jvshore7528]

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.

Very excited to see your next video. The first two are so well explained and animated and paced.

[@kgt9535]

Very, very good depiction of the said subject, bro. I'll never look at hydraulic jacks the same again. I see them now in cross section form thanks to this animation 👍

[@DavidM2002]

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.

[@mckinleygarcia9828]

Amazing video, I appreciate you. Please keep at it, your good graphics and simple yet through explanations are perfect

[@selfmade128]

Very well illustrated & explained!

[@_BAD_MERC_]

I took all four wheels off my car in April and noticed the jack ran out of ooomph before reaching the top. No problem - added some jack specific oil and it never worked again. I still haven't spent appreciable time trying to see why - but I should. GREAT video!!!!

[@xnavyro]

Great job, always understood the principle buy not the mechanics. Excellent graphics, really helped me to understand, Thank You!

[@hallidaygift9550]

Waooooooooow, 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.

[@HypherNet]

Great work and congrats on the new channel (and a new sub!) I love this sort of explanation, and I've always wanted to see a good diagram of how this works. My only critique would be in explaining how pascals law works to increase force from the handle piston to the load piston. I think it would be clearer to just explain what's going on in simple terms and then talk about pascals law, I found it hard to follow. From my point of view: since the load piston is larger than the pump piston, pumping 1 unit of fluid from pump to load will raise it up less far, by the ratio of the surface areas. But because it's going less far, it must have greater force. Since the cross section area is proportional to the square of the radius, you get quite a bit of mechanical advantage for a small increase in radius. Some example of common numbers of force multiplication would have been cool to see, too: "In a typical jack, the handle ratio is about 10 to one, and the area 20 to one, so a 200x increase in force" or whatever. In any case, I look forward to your next video, if you choose to make more!

So cool its all so simple now, especially the part where cylinder diameter difference makes pressure work in our favor.

[@rugbyguy1rugby407]

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

[@1stprinceoflite]

I remember my dad's bottle jack from decades ago. I'm glad they now pump up a lot faster.

Although I know I exactly how a battle Jack works, its the best explained video I have ever seen

[@leovalenzuela8368]

Perfectly explained

[@danielthechskid]

My bottle jack also has a small bleed orifice hole in the side of the main cylinder just below the mechanical top end stop so that if you raise it all the way up the oil just sprays back into the reservoir preventing you from jacking against the end stop itself. The piston/ram stops lifting a few mm below the stop instead. I call it the lift limiter.

[@pedroasandoval2579]

idk if its been implemented yet but you could make some money of this idea

[@danielthechskid]

@@pedroasandoval2579 ? I didn't add this hole it came stock, it's a 2 ton rated jack that I bought years ago at an Aldi Foods store, IE the US branch of Aldi Süd.

[@soaringvulture]

@@danielthechskid A food store sells jacks? Seems strange.

[@danielthechskid]

@soaringvulture Yes, Aldi is strange like that. They'll have a different batch of random non-food items each week that when gone you never see again. They even used to occasionally sell computers that were Medion branded.

[@lololol533]

Very informative and very interesting. Thanks!

[@vman2kay]

This explains why you need to have the release valve stem loosened before you uses it (at least in my manual), because if you don't then the oil can't bypass the safety spring if the load is too much and can explode. Nice video!

Hydraulic jacks are just another form of lever. And like ALL levers, they "work" by trading force for distance. Operating the jack lever converts a small force over a moderate distance (pump piston) to a large force over a short distance (main ram).

[@carlosg1165]

Great description in how it works 👍👍👍👍👍👍👍👍👍👍👍👍👍

[@IlicSorrentino]

Perfection.

[@notmenotme614]

0:43 The saddle can be threaded so that you can easily place the bottle jack underneath what you want to lift, then screw the saddle upwards so that it engages with a jacking point or mounting bracket. I’ve seen some saddles have a concave cup shape thats screws up onto a ball shaped mounting bracket.

[@44punisherable]

This is why I always use a three point safety system when I'm underneath a vehicle. Wooden blocks, jack stands with the tab punched in and wheel chocks. Never rely on bottle jacks, just be very careful if you have to. Find a good rock or something
