How Hydraulic Jacks Work

Working on a project car? A hydraulic jack can lift it off the ground by applying only minimal force. This portable, handy piece of equipment has a wide range of applications, from earthmoving and material handling to mining and more.

If you’re asking yourself, “What is a hydraulic jack, and how does it work?” or “How can a hydraulic jack be used for my project?” read on to discover the basics you need to know.

What is a hydraulic jack?

Jacks, in general, are commonly used to lift heavy objects, especially vehicles. Need to change a tire or inspect the undercarriage of your vehicle? You’ll need a jack to do it. Hydraulic jacks are available in a range of sizes and lift weight according to their size, and they can be categorized by the type of force they use—either hydraulic or mechanical. Hydraulic jacks use hydraulic cylinders to do the heavy lifting, and they’re more powerful than their mechanical counterparts.

Hydraulic jacks work on the Pascal principle. They create pressure by using hydraulic fluid, typically oil, to move through the pump chamber and build up pressure in the jack, providing the lifting force necessary to raise heavy objects. In simplest terms, hydraulic jacks apply a small force in a concentrated area. The pressure is then applied to a wider area to provide adequate force to lift the load.

Why do we need hydraulic jacks?

Hydraulic jacks are useful and convenient, particularly if you’re working on projects that require heavy lifting. In some cases, multiple hydraulic jacks are necessary to boost their functionality. Luckily, they are easy to use and lightweight. If you’re working on a project car, for example, you can use a hydraulic jack instead of heavy-duty, expensive equipment to lift the object. They’re also very safe, and anyone can use them by taking a careful approach.

How can a hydraulic jack be used for my project?

There are many projects and applications that are more convenient with the help of a hydraulic jack. Some of the most common applications include:

  • Lifting heavy loads in industrial settings
  • Material handling
  • Earthmoving
  • Lifting cars or other vehicles to change tires

Advantages of hydraulic jacks

If you need to lift a heavy load, a hydraulic jack is a useful tool to keep handy. Some of the advantages of hydraulic jacks include:

  • Space-saving: Hydraulic jacks occupy much less space compared to other lifting mechanisms and tools.
  • Heavy lifting: Hydraulic jacks are highly effective at lifting heavy loads, safely and with a minimum amount of effort.
  • Lightweight: Hydraulic jacks are typically lighter than screw jacks, making them easier to maneuver.
  • Easy-to-use: Hydraulic jacks are easier to use than screw jacks and are less likely to jam from rust in the screw thread.

Now that you understand what a hydraulic jack is and how it works, you can make an informed decision on whether to use it for your next project. Contact Zo-Air Co Inc. to learn more about the types of hydraulic jacks and their applications.
