The Science Behind Hydraulic Lift Tables

Hydraulic lifts are able to move so much weight because of the science behind hydraulic systems. Let’s take a closer look at the science, and how Lange-Lift tables are able to lift heavy loads so easily.


A hydraulic system is a type of technology used to move or lift things by applying pressure on a liquid inside a piston. But what does that look like? Well, here’s a video from our YouTube channel showing one of our tables in action.


Basically, these tables are able to move so much weight because liquids are incompressible. This means no matter how much force you apply on a liquid, you cannot reduce its volume. Think of a balloon. You can squeeze it and squash it, the liquid will move around inside the balloon and change the shape, but the volume remains the same.

If you put liquid into a pipe and apply force down on one end, then there is pressure building up.  The built-up pressure means the water has nowhere to go but out the other end. This is the driving force behind hydraulic lifts. The size of the pipes, how much downward force you apply, and the surface area of the pistons all determine how much pressure you need to apply to the liquid inside the piston to create enough force to lift up something really heavy.

Types and Uses

Hydraulic system technology is used in all kinds of things, from construction equipment to the brakes in your car. This technology is a critical part of engineering. Without it, many of the buildings, roads, and infrastructure in the world would not look the same. Moving heavy objects requires serious work, and hydraulic lifts are one really awesome hack to do it with ease.

Now, this was a very basic explanation of the science and physics behind hydraulic lifts. Here’s a video explaining the equations of force, pressure, area and more. There are specific measurements and calculations that need to be done to really make it all happen. Luckily, we’ve done the math already and built the lift system for you. Got a specific job? Don’t worry! We build custom lifts tables too, and you can always contact us with any questions.
