Hydraulic pressure is pretty crazy, power densities can get insane.

I mean, a human being can lift a car with very little effort.

It's also why most earth moving equipment is hydraulic.

The only really limiting factor is the pressure holding ability of your cylinder wall and the sealing surfaces.

Hey you wanna lift 6000T, hydraulics will do it!

It doesn’t take less effort, it is just stretched out over an amount of time necessary for your body to keep up. And yes I know I sound like an pedantic jerk, but I work on hydraulic systems every day and know how they work 😅
