The most necessary things that every motorist should have are a jack, a cable and a balloon. Fortunately, now all this can be bought at any auto shop. We are not looking for simple ways and will talk about how to make homemade jack for auto.
and their features
First of all, I would like to draw your attention to the fact that there are several actual designs of jacks. The most popular are hydraulic, rolling and mechanical. Each type has its own advantages and disadvantages.
Mechanical jacks are very reliable, but most models are not designed for heavy loads. Hydraulics lift large masses, but very often oil leaks from under the gaskets at the seals. As for pneumatic, this is one of the most best options. Making a homemade car jack is not so difficult, let's see how exactly. Let's start with the simplest.
Do-it-yourself rolling jack
One of the most popular types lifting devices car - rolling. It is called so not because it can be transported on wheels from one corner of the garage to another. The principle of operation is that while lifting the car, the jack moves under the car. This happens due to the displacement of the lever in relation to the fulcrum.
As a basis for the upper and lower arms, a channel can be taken, as well as a pair of corners. It is worth paying attention to the fact that the jack itself can be hydraulic or pneumatic. The first option is more lifting, the second is less problematic in terms of maintenance. The displacement of the rolling jack is possible if there are two pairs of wheels, and this is the main condition.
On the advantages and disadvantages of the design
This drawing of a homemade rolling jack shows that in terms of necessary tool and material construction is quite expensive. Unless, of course, you have half the material in the garage that is there as junk.
From the material you will need a channel with 4.5 mm walls and 7.5 mm thick shelves. Also needed welding machine and the old bottle hydraulic or conventional Do not make the levers too long, 400-500 mm each. But if it was done that way, you should think about making an additional emphasis. The advantage of such a jack is that it is convenient to use. But at the same time, carrying it with you in the trunk is not the best thing. The best decision. Best used as a stationary "garage" tool.
Hydraulic homemade jack
This is one of the simplest, but at the same time effective designs. For manufacturing, you will need a support platform. Its strength and rigidity should be as high as possible. This can be achieved with the help of additional stiffeners.
An important step is supporting structure, which is made of a profiled square tube. It is desirable that its thickness be at least 10 mm. We use the old hydraulic type as a basis. It is worth noting that even in this case it will take quite a lot metal profile, welding, and effort.
With a responsible approach to work, you will receive a high-quality and reliable design. Nevertheless, it is worth calculating the costs in advance. If the amount is more than 2,000 rubles, then it hardly makes sense to bother with this matter.
Buy or do?
Of course, you can make a homemade car jack. But this is worth doing if this procedure is appropriate. Now there is a huge selection of jacks in stores at an affordable cost. For example, for 1,500 rubles you can get a solid diamond jack. It is reliable, stable and does not take up much space, which makes it easy to transport.
For 2,500-3,000 rubles, good quality rolling jacks are sold. They have good carrying capacity and are reliable, although they are extremely bulky and heavy. Rolling can be made. But this will require a lot of tools and material, which will ultimately result in serious costs.
A homemade car jack made by you personally will also have its advantages. If you approach the matter correctly, then the output will turn out robust design, the resource of which will be clearly higher than the purchased device. But it's easy to make a mistake here. For example, some welds, especially on the bend of the lever, can burst, and this, in turn, will lead to sad consequences. In any case, it's up to you. The drawings presented in this article will help you in making a jack on your own. But it can take a whole day off and a lot of nerves and materials. But if there is a tool, and there is a lot of metal in the garage, then it is definitely worth a try. Especially since you know how to make a jack with your own hands.
» From the presented material, you will learn how to make a garage rolling jack for lifting a car with your own hands, as well as consider drawings, photos and videos of the design. Motorists are well aware that when operating a car, it is often necessary to jack it up to change tires from summer to winter and vice versa, as well as camera punctures and for its repair it is necessary to remove and disassemble the wheel. With tubeless tires, too, “curiosities” happen. It’s not always convenient to mess with a standard car jack, as they say, “bent in three deaths))” For this reason, a rolling jack was invented, it is very easy to operate and maintain.
The design includes a hydraulic jack 2 t "bottle" base and a lifting arm with a rubber gasket "cushion" For the convenience of moving the jack, support bearings are installed Attention! the wheels are installed in such a way that they touch the floor surface only in an inclined position, and in the working position they are raised - this is done so that there is no slipping during the lifting of the car.
Lever arm has a peculiar shape, all dimensions and angles are given in the drawings. The lift is carried out by 50 cm from the floor level, which allows you to replace both wheels of the car without reloading the jack. At the end of the lever is a rubber gasket "pillow"
The lifting height of the lever is 50 cm.
General view of the structure.
The jack is placed on a movable platform.
Almost everyone has a car now. For some, it acts as a source of income - these are taxis, buses, cargo transportation, etc. Some people need it just to get around. But for true motorists, the car is the closest friend who helps out in difficult times and never fails. They take care of it, take care of it, repair it on time. Often such people in life are friends with technology and love the instrument. They like to do things with my own hands because it brings great pleasure. Often you get some useful and interesting gizmos for the car.
For example, it would be a good idea to make a jack. Indeed, not a single motorist can do without this device. Many, of course, will now say that it is easier to go and buy it in a store. But for a true mechanic to build such a thing, especially for his car, it will not be difficult. It is only important to know how to make a jack, and what it will consist of.
Before you start making a jack for a car with your own hands, you need to decide what design it will be. To do this, you need to know the main varieties of these devices that can be found in stores:
- Rack. This type has been used for a very long time. It is based on a long metal rail with holes, a lever and a ratchet with a perpendicular end. Pulling the lever down, the ratchet lifts the weight along with it. Pulling up - it works, locking itself into one of the holes closest to the rail along with the load. Then the cycle repeats again;
rack jack
- Screw. The most common jack among domestic motorists. It can be presented in different ways, but the principle of operation is the same - rotating, the screw raises or lowers the dynamic part. It is often made in the form of a strong lever attached to a movable mechanism, which in turn walks along brackets in the case. There is also a rhombic jack. It is much more practical and is a diamond-shaped body, which is made of four moving parts. A stand is attached at the bottom, and a lifting platform is attached at the top. A long screw passes through the side mounts. If you twist it, the figure will either fold or stretch upward, lifting the load;
screw jack
- Hydraulic. Most often, such devices can be found in truckers who lift heavy truck axles when changing wheels. They can be presented in different ways and have different principle work, but the meaning is the same for everyone - there is hand pump which creates oil pressure in the master cylinder. Under its action, a platform with weight begins to climb out. These jacks are characterized by high load capacity, as well as large weight and height;
Hydraulic jack
- Pneumatic. It is somewhat reminiscent of an air balloon, which are installed on the air suspension of a car. Simply put, this is a small platform on wheels (maybe without them), on which a hollow, thick-walled rubber cushion is attached. Air is supplied through the fitting from a compressor or cylinder. Pressure builds up and the pillow begins to rise.
pneumatic jack
These are the main types of jacks that are used most often. They are classified precisely according to the type of force used (mechanical, hydraulic, etc.), but there are many varieties of them. For example, hydraulic devices are haulage, cylindrical, trailer, two-level. That is, there is one type of jack, and there are several types of it. Therefore, there is a great choice in order to independently make your own model using a prototype.
Skills required in the manufacture of a jack
It should be said right away that needlework is not an easy task and requires certain skills. In our case, these are almost all the abilities that a novice mechanic should have:
- welding- the most basic thing that is required when working with metal. Since the structure will be assembled from scratch, it will only need to be welded. Moreover, this must be done with high quality, so that in the end a durable product is obtained;
- cutting- it is enough to be able to cut iron with a grinder. Well, if you have the skill of cutting with an oxygen torch;
- treatment- no skill in using a file or grinder it'll be hard;
- turning case- in principle, you can do without it, but if you are fond of it, it will be much easier in the manufacture and processing of some parts;
- painting- a hand-made thing must be painted.
If you have the above skills, then in the process of making a jack, no problems should arise. The higher the skill level of the tool, the better the product will turn out.
In order to make a jack, there must be suitable tool. The first step is welding, since it will be assembled with its help. It is desirable that this be semi-automatic apparatus with carbon dioxide. Then the seams will be much smoother and there will be no excess slag. Second, and no less important, is Bulgarian. Well, if the assortment has both small and large. With their help, you will cut blanks from steel. You will also need drill, because you have to make more than one hole. In order to easily process iron parts, it is necessary electric sharpener. It is key in the fitting process. In addition, it is desirable to have hand tools : files, needle files, bars, hammers, screwdrivers, rasps, lehrs with a set of taps, sledgehammers, vise, etc. The more tools at hand, the easier the manufacturing process will seem.
The more tools available, the easier and better the jack will turn out.
Lathe in any business is an excellent assistant, but not everyone has it. In principle, you can cope without it, but if you have such a unit in your garage or workshop, it will turn out much faster. After all, with the help milling machine easy to carve or process any detail. For example, a bolt or a rod. In general, your machine will be very handy.
It is also worth talking about the material. It can be bought at the market or at the scrap metal collection point. The second option is much cheaper, since all the metal is rusty and battered at scrap receptions. It is not suitable for operation, but as a donor, that's it. It is desirable, of course, to buy more of everything. Indeed, depending on what kind of jack you want, you may need additional mechanisms or fasteners that you cannot make yourself. Therefore, be prepared to purchase some components on the market.
The base (both the lifting arm and the lifting platform) of the hydraulic jack can be made from a channel. For lifting force, a conventional hydraulic bottle jack is used. To move the jack, you can attach wheels (can be replaced with bearings, rollers or something similar).
The device of a homemade hydraulic rolling jack
It is recommended to install a bottle jack on a movable “swing” platform, since during operation the jack slightly changes its angle, and some movement compensation is required. The platform should sway slightly from side to side. You can make it from the same channel by drilling through hole in the lifting base and putting the "swing" on the bolt so that there is a small gap of 0.5-1 cm between the base and the platform.
Movable platform for bottle jack
To increase the strength of the structure, it is desirable to make braces of rods on both sides of the base. The thicker the rods, the better. They are welded to the base.
The device is powered by a bottle jack. When it is set in motion with a special rod handle, it rises, which moves the lifting lever up.
The process of operation of a homemade hydraulic rolling jack
A drawing of such a hydraulic jack for making it yourself is shown in the image below:

As an example, consider also a pneumatic device that easiest to do. So, you will need:
Basically, such homemade device you can easily lift any a car. It is enough to substitute the pneumatic cylinder under the platform on the bottom and connect the hose high pressure to the fitting. By supplying compressed air, the pillow will begin to rise with the machine.
The principle of operation of a homemade pneumatic jack
For convenience, such a jack can be completed by inventing a reliable platform with wheels for it. Thus, if the cylinder is taken for disassembly, then the device own production goes for almost a penny.

The most important question remains. Is it worth it to make a jack yourself? The answers to it may be different, however, after weighing all the nuances, you can come to the final conclusion. To begin with, it is worth understanding the cost. It is clear that no one will buy a tool for manufacturing, however, you will need material and some parts that you still have to purchase. It is quite possible to buy a new factory jack for 5,000 rubles. Waste on homemade will depend on what kind and type it is. So, making a hydraulic one will be the most expensive, but the pneumatic one discussed above is the cheapest.
In general, the cost of a jack is not so big to rack your brains and make it yourself. If you don't care, then it's better not to take it on and buy a new one in the store. But, if the process itself is interesting, and you want to make something, then this great idea test your skills. You may even be able to save 1-2 thousand rubles. That is, when there is a desire to do - try, be wiser and achieve results. But if the process of making a jack is not interesting to you, then it is better to postpone this matter.
The main thing to remember is safety measures. Any tool in inexperienced hands can cause serious injury. Remember to also wear protective goggles when working with metal and when welding to protect your eyes.
How to make a jack with your own hands: instructions with photos and videos
5 (100%) 5 votedA jack is a device that should be located both in the trunk of a car and in the garage of a car enthusiast. At the same time, it is better to choose the second option more massive with universal functionality and a high load capacity. These characteristics are 100% do-it-yourself, which will not be difficult to do.
Characteristics of the pneumatic device
There are three main criteria by which a homemade inflatable jack is evaluated:
- load indicator. To ensure safe operation, this value must exceed the weight vehicle. For a passenger car, a characteristic of about two tons will be enough; maintenance of heavier vehicles requires a carrying capacity of at least 2.5 tons.
- Pickup height. This aspect plays important role if the vehicle has low ground clearance. The optimal indicator is a value of at least 100 mm.
- Lift level. Homemade pneumatic type jack has a height of not more than 500 mm. This reserve is quite enough for changing wheels and some other work, the rigging unit with connection to the compressor allows you to raise the car up to 70-80 cm.
Definitely, when choosing a jack and its manufacture, first of all, you need to focus on your car, the conditions for its operation and storage.
How to make a jack yourself?
To build a jack with your own hands, you will not need much material and effort. You need to select the following items:
- a used pillow from a truck;
- suitable bolt;
- ball element;
- wheel VAZ lock;
- union;
- drill as the main tool.
The structure is assembled from the presented elements. A bolt is screwed into the hole in the pillow. First you need to make a socket for the fitting from the camera.
A wheel bolt from a VAZ is used as a valve, in which a hole is drilled. At the next stage, the existing elements are connected after a ball is installed in the hole, which will serve as an air intake.
Peculiarities
For practical implementation This device requires a special pump. The inflatable jack is installed under the bottom of the vehicle. For insurance, it is advisable to use wooden stand, which will interact directly with the machine.
This mechanism has one significant drawback. Since the cargo cushion has a decent size, a low-slung car will have to be raised beforehand to install the device in question. If you attach a cart with wheels to the bottom of such units, you will get home-made ones for cars.
Comparative characteristics
The pneumatic version lifts the load due to the compression force of the air mass. Such modifications work from connection to additional equipment or from the exhaust of the machine. The air mass enters the chamber. Due to compression and increase in volume, the car rises. The advantage of the models is that you do not need to make special efforts, and in the presence of a compressor unit, the process takes a matter of seconds.
A mechanical jack for a car involves bringing it into operation by rotating or twisting a special handle. Such modifications have a low price and compact size.
The principle of hydraulics is similar to the mechanical version. The difference lies in facilitating the process of pumping out the working part of the jack, due to the presence of liquid in the working system. Such modifications are long term services.
A mechanical jack with an electric drive is powered by mains power, all the main work of the device is performed by electricity. The advantages of the device are undeniable, but you need to connect it to the outlet.
Security measures
Despite the fact that the inflatable jack is one of the most elementary in terms of operation, its use requires certain precautions.
To prevent the unit from flying out from under the car, it must be installed correctly. Before installing a new pneumatic device, it is advisable to deflate it once without load, after which it descends and fits itself accordingly. To protect the jack from damage, it is better to lay a rug on the floor.
For the manufacture of the working chamber of the device, materials based on PVC are suitable. At sub-zero temperature such a design hardens and becomes rough. According to experts, the best temperature regime operation is an indicator of up to -10 degrees.
Hydraulic lifting device
It is quite possible to make a hydraulic jack with your own hands. It is based on a body, the main bearing function is performed by a retractable piston and a working fluid (oil). Variations of the fixture can be made with a shortened or elongated steel frame. The housing is a reservoir for oil and a guide cylinder for the piston.
A special adjusting screw with a lifting heel is screwed into the plunger, if necessary, you can increase the maximum lifting height. Such a device is equipped with a manual, foot or air type drive.
The working mechanism and the retractable cylinder are located in the holes of the frame. The unit is lowered by turning the T-handle. Some devices are equipped with polyamide wheels that provide maneuverability. Operational safety is ensured by safety valves.
Positive and negative sides of the hydraulic device
Before you make a jack with your own hands, you should consider all its pros and cons. The advantages of a hydraulic device include the following indicators:
- the device is unpretentious in maintenance and operation at a fairly high power rate;
- smooth running of the working rod, reliable fixation of the load at the desired height, braking accuracy;
- high efficiency (up to 80%) and load capacity (over 150 tons).
The disadvantages of using the hydraulic model include a high initial lifting height, the problem of the accuracy of lowering position control, a decent price and a rather large weight. Store and transport the device only vertically, otherwise the working fluid may leak out.
Conclusion
Making a jack with your own hands will not be a particular problem. Depending on the possibilities, the scope of use and other objective circumstances, you should choose the right model for the type of work. For use on the road, a compact device of a mechanical or hydraulic type is suitable, and in the garage an inexpensive and practical pneumatic device will work perfectly.
