Let’s start with the basics. An automobile jack is a lifting tool used to lift a car off the ground. It can be either hydraulic or mechanical. Hydraulic jacks utilize hydraulic power to lift heavy loads or apply great forces.

A hydraulic cylinder filled with pressure creates the forces needed to lift heavy loads. Conversely, a mechanic jack utilizes a screw thread to lift a car entirely or partially off the ground.

A car jack is also known as a floor jack or garage jack. However, it allows someone to lift vehicles to perform maintenance. A hand jack for a car can lift around 1.5 tons to 3 tons. Industrial jacks can lift many tons of load.

What is a Jack Used for?

Car Lifting Jack Types and Their Mechanism

There are two basic types of car jacks, depending on their mechanism.

  1. Mechanical jack
  2. Hydraulic Jacks

Mechanical Types of Jacks for Lifting

A mechanical car jack uses a simple mechanical method to lift a vehicle. These car jacks utilize a screw to raise and lower a hinged mechanism slowly. Or they gradually use a ratcheting system to lift the vehicle at a time.

How Do They work?

While a screw jack unit operates, the rotation of the worm shaft forces the worm gear to rotate. The worm gear is attached to the lead screw, and it helps rotate the screw jack.

So, both rotate at the same speed. When the warm gear rotates, the frictional force of the screw thread also rotates the nut. These categories of car jacks include a scissor jack and high lift jack – savior of an off-roader.

Hydraulic Types of Jacks for Lifting

Hydraulic jacks utilize a vertically or horizontally placed hydraulic cylinder to lift heavy loads. These jacks use the fact that the liquid is not easily compressed. Floor jacks and bottle jacks are some of the types of hydraulic jacks.

How Do They Work?

Hydraulic jacks are made of a reservoir full of oil. Some of that oil is drawn from the reservoir on the handle’s surface. At the bottom, that part of the oil is forced into the central cylinder and under a piston.

As the amount of fluid under the piston increases, the pressure pushes the cylinder upwards. It will remain up there until the oil comes out and flows into the reservoir.

Different Kinds of Car Jacks

Now you have been familiar with the two basic systems used by the car jack. Many types of car jacks use these two basic systems. Let’s get familiar with them.

However, bottle jacks are pretty compact, making them suitable for garage storage.

Hydraulic bottle jacks come in a range of lifting capacities.

The average size of a bottle jack can lift at least 2 to 12 tons. They can also lift jumbo sizes ranging from 20+ tons to 100 tons. Above all, it’s very easy to use, even for new car owners.

Besides, it takes no time to install it in position. The hydraulic pressure allows raising and lowering a heavy vehicle using the long handle. The low-profile design makes it an ideal option to work under the car.

Also, it makes an ideal choice for some light construction projects. However, picking the right size is mandatory. They are small enough to fit among the littlest riders out there. Floor jacks require little to no experience to use.

In addition, they are compact and lighter. You can fold them between uses. Scissor jacks are really very easy to use. Like other jacks, it requires no maintenance except for keeping it clean.

4. Trolley Jack

The trolley jack can roll in dirt and stones. Besides, it has a braking mechanism. It makes the jack one of the safest jacks for a range of applications. Trolley jacks can lift up to 4 tons and are generally used for automotive repairs.

It pumps the cylinder oil by lifting the jack handle. As soon as you lower the jack handle, it pushes the pressurized oil towards the main cylinder. It helps the main piston to lift.

5. High Lift Jack


The high lift jack is mainly designed for off-roading. This non-hydraulic car jack is not what you may find in every garage. It comes in handy when lifting a heavy trailer out of the mud.
