Illustration of Pascal's principle at work in a hydraulic press. According to Pascal's principle, the original pressure (P 1) exerted on the small piston (A 1) will produce an equal pressure (P 2) on the large piston (A 2).However, because A 2 has 10 times the area of A 1, it will produce a force (F 2) that is 10 times greater than the original force (F 1).

Given the high pressure ratings of most hydraulic pistons, it is possible to generate tremendous actuating forces with a hydraulic actuator, even if the piston area is modest. For example, an hydraulic pressure of 2000 PSI applied to one side of a 3 inch diameter piston will generate a linear thrust exceeding 14000 pounds (7 tons)!

When a piston applies force in one direction (down), it pushes the oil against another piston, driving it up with all of the original force. A pump creates the necessary pressure. Most hydraulic cranes have a two-gear pump that pressurizes the oil. Of course, there are other simple components that make a hydraulic crane functional.
