A jack is a device that no driver can do without when repairing their car. It is needed to lift loads to a small height. It should be stored in the trunk of a car or in a garage. When purchasing such a device, you need to pay attention to the load capacity, which should be as high as possible, as well as the universal functionality. Many car enthusiasts prefer a hydraulic jack, which you can build with your own hands. But before that, you need to study information on how to make a homemade car jack with your own hands at home.
Types of jacks
There are three main types.
Mechanical jack. The car is lifted by pressing the handle. They are used quite rarely because they require some physical effort. The advantage is that they take up little space;
Hydraulic jack. Similar to the first option, but here you need to apply less physical force. All processes for lifting a car are carried out using liquids;Pneumatic jack. Lifting is carried out thanks to compressed gas. Does not require any physical effort.

Working principle of pneumatic lift
A pneumatic jack works using the properties of compressed air. In the sealed chamber, into which the air pumped by the compressor enters, high pressure is gradually created.
Rubber cushions that expand under the action of compressed air rest against the load and gradually raise it to a predetermined height. At the end of the work, the air is released, the pressure inside the cushions decreases and the load is smoothly lowered.
In the process of repairing a car, service station specialists and car enthusiasts use a variety of options for pneumatic lifts - from rolling pneumatic jacks to polymer inflatable cushions and home-made structures.
Rack jack
The stability of this type of jack is determined by the strength of the fixation and the supporting platform.
To make it, take 2 pipes and welding. The finished product should resemble a stripped-down pyramid. After this, take a steel sheet, half a centimeter thick. Cut out 2 jack bases.
Drill a hole at the top and weld a nut there. You also need to drill a hole at the bottom. After this, insert a spiral there for rotation.
You can make small repairs and upgrades to this jack yourself. Install the cable, and it will serve as a winch if necessary.
These options are the simplest when making jacks with your own hands. Let's hope they will help you solve your pressing problems. No nail, no rod for you.
Manual lift for lifting a car
This device is not a jack in the truest sense of the word. However, this is one of the types of mechanical lift.
The idea of making this device belongs to the author of the YouTube channel “BOBKA TV”.
First of all, we prepare the necessary parts. To do this, we use the following materials: profile pipes, strips of metal and a piece of round pipe (we cut the round pipe blank lengthwise and use one of the resulting halves).
Next, we proceed to the manufacture of a homemade device. We weld a piece of round pipe to a section of professional pipe, as shown in the photo below.
We weld another piece of corrugated pipe to the opposite end of the profile. We weld a stand from a long section of profile pipe to it - it will act as a lever. A handle must be welded to the top of the rack.
Next, install the wheel axle from a threaded rod and weld it. We weld a piece of profile with furniture wheels to the stand.
We clean the welds and start painting. After this we install the support wheels.
The principle of operation of a homemade device is very simple. We rest the trolley against the bottom of the car. Then we press on the lever with our own weight and lift the car. In this case, you no longer need to press the lever.
The step-by-step process of making a homemade rolling jack is shown in the author's video.

Classification of pneumatic jacks
Pneumatic lifts that are used in the repair of various vehicles can be divided into four types:
- portable;
- rolling;
- ditch;
- platforms.
Portable type jacks
Portable pneumatic jacks are a rubber or polymer cylinder with strong elastic walls. To lift the vehicle, this cylinder is filled with air, which is pumped by a compressor, or exhaust gas from the vehicle's exhaust pipe.
Despite the fact that this design looks quite flimsy, it is able to provide a lifting force of about 3...4 tons. At the same time, the time it takes to lift the car does not exceed 2...3 minutes.
In addition, portable pneumatic jacks:
- do not require maintenance, since they have no wearing parts;
- can be used even in cases where there is no flat hard surface under the car.
Rolling tackles
A rolling-type pneumatic jack is a trolley on wheels equipped with an elastic air cushion and locking elements that ensure the immobility of the structure after installing it under the car.
Air spring jacks provide lifting of the car to a height of up to 50 cm.
To hang a vehicle, a rolling jack is installed under its bottom, after which it is connected to a high-pressure compressor. Using a compressor that forces air into the air spring allows the jack to raise the car to the required height in a few seconds.
Ditch
A ditch pneumatic lift (crossbeam) is necessary in cases where it is necessary to adjust the wheel alignment angles or perform other types of repair work for which one of the vehicle axles needs to be suspended.
Its use allows you to create additional space in the repair area, which makes the repair more comfortable. In addition, the traverse can move along the axis of the inspection hole, so it can be placed in any place convenient for the car mechanic. Mount the traverse on an inspection hole or post lift. On the market you can find models with a lifting force exceeding 4 tons.
Structurally, the ditch lift is a frame with a lifting beam and a powerful air spring. At the same time, the locking mechanism makes it easy to fix the lifting beam at the required height.
For frame cars, the design provides quick-release extensions with replaceable rubberized heels. When lifting the car, the entire load is transferred to the frame. This jack is equipped with a reinforced three-section air spring with special reinforcing belts in rubber casting.
Pneumatic platforms
The pneumatic platform is designed to quickly lift a wheeled vehicle to a height convenient for high-quality tire mounting.
Using such a platform, you can hang the entire chassis of the car and service all 4 wheels at the same time.
At the same time, in addition to tire fitting work, other types of minor repairs can be carried out, such as, for example, replacement:
- ball joints;
- steering tips;
- brake pads, etc.
Using a pneumatic platform, you can lift the car to a height of about 400...500 mm. In this case, the device is equipped with a special safety stopper, the lever of which must be set to the load securing position upon completion of lifting.
Selection criteria when purchasing
The domestic market of equipment and accessories for car repairs offers a large number of different lifting mechanisms, among which pneumatic jacks occupy a relatively small niche.
Experts advise car enthusiasts when choosing a pneumatic jack to pay special attention to:
- the amount of carrying capacity, which must be at least 200...300 kg greater than the weight of the vehicle being lifted;
- lifting height;
- pick-up height, which should not be greater than the vehicle’s ground clearance;
- the maximum permissible pressure in air bags, based on the fact that low-pressure bags are only suitable for lifting passenger cars.
In addition, when choosing a pneumatic jack, you need to clearly understand what it is needed for. For example, if you have to take it with you on a trip, then it should be light, mobile and compact, but when using a pneumatic jack in the garage, you can purchase a more bulky, but multifunctional unit.
When choosing a pneumatic jack for your car, pay attention to the manufacturers of this type of equipment. Keep in mind that only high-quality equipment makes it possible to repair a car quickly and comfortably. After all, if the materials from which the pneumatic chambers and hoses are made are not afraid of punctures and cuts, then the pneumatic jack will serve you for a long time.
