Motorists, and especially those who like to spend a couple of free hours in the garage, are people who have genetic level a talent is developed to obtain practical benefits from available things. They don’t have to be persuaded to try new experiments or try out a new way to fix, assemble, or remove something without owning a specialized tool.

Why invent something new when in three or four hours and practically for free you can assemble a jack with your own hands– useful, practical and indispensable tool for every car owner.

The photo shows types of jacks and methods of their use

Car jack - universal device, capable of supporting structures weighing up to two tons, and sometimes more, for days. It's like a third hand for a car mechanic: super strong, durable and one hundred percent effective.

Simplicity of design and abundance of varieties functional tool allows you to make an exact analogy of any branded jack with your own hands.

How to make a screw jack

The classic and most common diamond-shaped jack is the screw jack. Make one like this DIY jack- a matter of two hours, especially if you have one and a half to two meters of channel and a basic set of fasteners. The compact tool will easily fit in the trunk, and in any emergency and unforeseen situation you will praise yourself for your foresight and intelligence.

Many people know how to assemble a jack from a channel, but have never tried it. There are only five elements, and the tool is already 90% ready:

Levers made of bent steel channel with equal flange sides - 4 pcs;
Channel fragments for the lower and upper arms (the lower arm can be replaced with a wider and more stable base);
Rubber gasket (on the upper shoulder, for the jack);
Axles holding the upper and lower arms (pins with heads on the axle, secured with cotter pins);
A threaded screw secured to the shaft on one side.

On preparatory stage Drill holes at the joints of the elements, and then begin assembly. Connect the shoulders, secure them together and on the bases. Insert a threaded screw into the shaft and check homemade jack on lifting force.

The photo shows a diagram of the screw jack assembly

As you can see, a simple method that does not require welding and professional equipment (except for an electric drill), takes only an hour or two of time, and does not damage the budget.

How to make a jack from an air spring

It’s a completely different matter when a jack is needed for more serious work than, for example, changing a wheel on the road:

Lifting vehicles weighing more than 2 tons;
Work in the inspection pit;
Professional activity in car service;
Lifting a car in hard-to-reach places.

In cases where classic screw models cannot cope, homemade hydraulic jacks made from air springs come to the rescue: they are relevant not only for cars, but also for other heavy-lifting loads - safes, workbenches, large-sized furniture.

To build a homemade air jack, you will need a minimum of materials:

Air spring from a bus or truck;
Air hose + supply and bleed system;
Cushion stand + car lining;
Compressor (which, by the way, can also be made with your own hands).

Details about how to make a jack with your own hands from an air spring, watch the video https://www.youtube.com/watch?v=vg8z68ObTEA.

In the same way, you can make a pit “lift” (for an inspection ditch), or rolling jack: The type of air bag does not matter.

How to make a rack and pinion jack

He always comes to the rescue when other models are powerless, and human imagination and physical capabilities are exhausted. A rack and pinion jack will help if you need:

Raise the motorcycle to a height;
Lift a truck, bus, train or truck body;
Pull the car out of off-road conditions (mud, sand, swamp, stones);
Raise the car by the tow bar.

There are no secrets in how to make a rack model; it only takes three steps and about an hour of time:

From the existing slats, weld one, elongated (1.5 - 2 meters, depending on needs);
Weld a stable base to them;
Put on top a jacking mechanism with a heel, found in the bins of the garage (or purchased by agreement with a neighbor).

If desired, it is possible to additionally make fasteners for such a device, allowing you to lift the car by the wheel rims.

Simple manipulations and a little spatial imagination will allow you to save money and assemble the device with your own hands, without which not a single replacement of wheels or other parts of the suspension is complete. And when the right approach and proper use of resources, a homemade jack will help you out in many situational troubles.

The most necessary things that every motorist should have are a jack, cigarette lighter wires, a cable and a cylinder. Fortunately, now all this can be bought at any auto store. We are not looking for simple ways and will talk about how to make a homemade jack for a car.

Types of jacks and their features

First of all, I would like to draw your attention to the fact that there are several current 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. Hydraulic ones lift large masses, but very often oil leaks from under the gaskets at the seals. As for pneumatic ones, this is one of the most optimal options. Making a homemade car jack is not that difficult, let’s see exactly how. Let's start with the simplest.

One of the most popular types lifting devices car - rolling. It is called that 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 relative to the fulcrum.

A channel, as well as a pair of corners, can be taken as the basis for the upper and lower arms. It is worth paying attention to the fact that the jack itself can be hydraulic or pneumatic. The first option is more load-bearing, the second is less problematic in terms of maintenance. Displacement of the rolling jack is possible if there are two pairs of wheels, and this is the main condition.

About the advantages and disadvantages of the design

This drawing of a homemade rolling jack shows that in terms of the necessary tool and the material design is quite expensive. Unless, of course, you have half the material sitting in your garage as unwanted junk.

The material you will need is a channel with walls 4.5 mm and shelves 7.5 mm thick. Also required welding machine and an old bottle hydraulic or regular pneumatic jack. You should not make the levers too long, 400-500 mm each. But if this is how it was done, it’s worth thinking about making an additional support. 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 The best decision. Ideal for use 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 great as possible. This can be achieved using additional stiffeners.

An important step is supporting structure, which is made from profiled pipe square section. It is desirable that its thickness be at least 10 mm. We use the old one as a base. hydraulic jack bottle type. It is worth noting that even in in this case you'll need quite a lot metal profile, welding, and effort.

With a responsible approach to work, you will receive a high-quality and reliable design. However, it is worth calculating the costs in advance. If the amount turns out to be more than 2,000 rubles, then it hardly makes sense to bother with this matter.

Buy or make?

Of course, you can make a homemade jack for a car. But it is worth doing this if this procedure is advisable. Now there is huge selection jacks in stores at an affordable price. For example, for 1,500 rubles you can get a good-quality diamond-shaped jack. It is reliable, stable and does not take up much space, making it easy to transport.

Good quality rolling jacks are sold for 2,500-3,000 rubles. They have good load capacity and are reliable, although they are extremely bulky and heavy. You can make a rolling jack with your own hands. 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, the result will be reliable design, the resource of which will clearly be 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, may burst, and this, in turn, will lead to dire consequences. In any case, it's up to you. The drawings presented in this article will help you make your own jack. But this can take a whole day off and a lot of nerves and materials. But if you have a tool, and there’s a lot of metal in the garage, then it’s definitely worth a try. Moreover, you know how to make a jack with your own hands.

Summarizing

The problem of lifting large loads has been facing humanity for quite some time. IN last years To solve this problem, jacks are increasingly being used. The hydraulic jack stands apart in this series. He is capable of lifting really heavy loads with a minimum of effort. Hydraulics, since the advent of science, has come to the aid of man. There are situations when a lift of this kind is simply necessary, but there is no way to purchase it. How to make a homemade jack?

Scheme of a rolling hydraulic jack.

Design and its features

Of course, before you start working, you definitely need to learn more about the design of a hydraulic jack. In fact, it is not as complicated as it might seem at first glance. The main elements are a housing, a pump, a plunger, and a screw with a lifting heel. A hydraulic jack is most often made of hardened steel. At the same time, as working fluid is a special oil with high viscosity. Regular motor oil will not work in this situation.

Hydraulic jack device.

It is worth taking this into account when developing the device. Typically, the body is the main part of a hydraulic jack. It serves not only as a reservoir for the working fluid, but also as a real cylinder for the piston. The device of this design implies the presence of safety valves that provide uninterrupted operation. It is equipped with a hand or foot pump.

The oil is drained using a special handle, which is part of the mechanism. The lifting mechanism and a special retractable hydraulic cylinder are capable of raising the working platform. Enough is being created high pressure, which allows you to lift loads of various masses. The body of such a device can be either short or elongated. The second option is most often used when carrying out repair work heavy equipment. For example, it could be a bus or a heavy vehicle.

Main characteristics

Screw jack device.

There are many options that allow you to use hydraulic jacks everywhere. They are unpretentious in terms of carrying capacity. An important point is the presence of practically incompressible working material. We are talking specifically about hydraulic oil. From this we can draw conclusions that it is impossible to avoid smooth operation, that is, raising and lowering. In this case, the load can be secured at almost any height. It is worth noting that such devices have a fairly high efficiency, which is 80%. At the same time, the lifting capacity of the mechanism can reach 200 tons. Of course, such powerful units will not be considered in this work, but the reader should know that they exist.

It is necessary to note the initial height of the rise. This indicator is better than that of ordinary mechanical models. Loads can be lifted from almost zero height. This is very convenient, especially when we're talking about on carrying out repair work on low-slung vehicles.

The device of the simplest homemade jack.

There are, of course, disadvantages to hydraulic jacks. The main thing is that it is very difficult to regulate the lowering height in such mechanisms. To ensure that the device is always in working order, it must be checked. Here you need to monitor the oil level, the condition of the valves, gaskets and seals. If necessary, these elements must be replaced. Sometimes difficulties may arise with transporting jacks. They must be stored and transported only in an upright position.

Otherwise, there is a high probability that all the liquid from the reservoir will simply leak out. Another disadvantage is the relatively large mass of the device. It is not always easy to transport it from place to place. The cost also makes many people think about alternative solutions Problems. Some people buy mechanical jacks because they are several times cheaper, while others make their own hydraulic jacks.

Manufacturing of hydraulic press

Hydraulic press device.

The hydraulic jack itself is not that interesting, since it is quite simple, but the press can be useful to every person who loves cars. It will serve as a real garage assistant. With its help you can press bushings, punch holes in various metal blanks. A hydraulic jack will be used to create pressure in the structure. For work you will need Sander, a welding machine with a certain number of electrodes and an angle grinder.

The first component in this design will be the support platform for the jack. Since you will have to work with quite impressive weights, it is necessary to make the platform as reliable and powerful as possible. Don't forget about this nuance. Achieving the required result is quite difficult. To do this, you will need to apply several stiffeners at once. This is the only way the design will truly be of the highest quality and reliability.

For work, you can use both square and rectangular profiles.

Drawing of a pneumohydraulic rolling jack.

Here the choice depends directly on the person’s capabilities and what he has at hand. Next, these parts of the structure are laid with the base facing each other. In this case, it is worth making as many welding seams as possible. This will achieve the required rigidity. The elements must be welded to each other both from below and from above. In order for the structure to be stable, it is necessary to additionally use a metal plate for the stand, the thickness of which will be at least 10 mm.

Next you need to make the emphasis and racks. To do this, you must first prepare a profiled pipe, the cross-section of which will be square or round. To calculate the height, you will have to add several values together. It is necessary to add to the height of the jack the value of the working stroke of the rod, as well as the height of the platform. The resulting number will become the result.

The stop must be made of the same metal from which the stands are made. Next, all the elements are connected to each other. The result is a U-shaped structure. In order to ensure the perpendicularity of all structural elements, you need to make a very simple device. On a steel plate, the thickness of which will be at least 10 mm, it is worth laying two corners at an angle of 90°. Next, all these elements are welded together. Everything is quite simple, but the design is truly as reliable as possible.

The lifting capacity of a screw jack is calculated using the formula.

In order to make it more convenient to work in the future, this device should be equipped with special clamping mechanisms. This will allow you to fix the resulting triangle and avoid its further displacement along the axes.

The next stage of work is the creation of a special stop that will move along the guides, transferring pressure from the hydraulic jack directly to the workpiece. To work, you will need to use a special metal piece. Its thickness should not be less than 1 cm. The length of this part should be slightly less than the distance between the posts.

It is worth noting that the components of the stop are connected to each other by welding. At the same time, you should not skimp on electrodes. Only good connection of all design elements will allow you to really make the most high-quality construction. Now you can proceed to the installation of the hydraulic jack itself. It is secured with two bolts of equal length.

It is worth making it as strong and rigid as possible. If you need to reduce the working stroke of the hydraulic jack rod during work, you will have to reduce the distance between the stop and the steel part of the structure, that is, its beam. For this, additional metal plate the corresponding profile.

In order to make this distance less impressive, you can use additional removable inserts. They should be additionally marked in order to ensure that tools can be changed as quickly as possible during the work process.

Summarizing

So, the above has revealed the advantages of hydraulic jacks. As is clear, this device can be used not only for its intended purpose. For the press garage type it is quite appropriate. In this case, the hydraulic jack becomes one of the best options to create such a press. Of course, this is not the only such case of non-standard use of a hydraulic jack in practice. The hydraulic jack itself is extremely simple to make.

Knowing the design of this device, you can experiment with its designs. This is a great solution for every car enthusiast. The hydraulic housing is made of hardened steel. Don't forget about quality materials for the piston itself. He will have to transfer the maximum load. Only hydraulic oil should be used as the working fluid. It has high viscosity.

Only such oil is capable of creating high pressure in the working mechanism. Knowledge will allow everyone to make a hydraulic jack and press with their own hands.

It’s very easy to make a homemade, convenient car jack from scrap materials! In the video there is a short overview, if you are interested in anything about this invention, ask questions. and suggestions!

The main function of a jack is to lift a car wheel in order to replace it or a tire. The jack is used for self-replacement car wheels in the absence of repair services. Also, sometimes you have to crawl under the bottom of the car in order to carry out repair work. The jack will come in handy in this case too.

Outside of the automotive field, jacks are often used to install structures at the required level during construction and repair work, when lifting loads in warehouses and spare parts in workshops.

You can read about how the crosspiece is replaced in detailed material our author.

You may also be interested in information on how to choose and securely fasten with your own hands.

The important characteristics of the jack are listed below.

Load capacity. Each of the jacks has limitations on this parameter. When manufacturing the device, it is necessary to take into account the weight of the vehicle. It is also necessary to take into account the weight of the cargo in the luggage compartment.
Lifting height. This parameter is especially important for cars with low bottoms. In this case, the lifting height must be acceptable to allow one to climb under the car and carry out repair work.
Pickup height. This is the height of the instrument. This parameter must be compatible with the vehicle's ground clearance (distance from the surface to the lowest point). This setting is different for each separate model. It is necessary to select the pick-up height so that it is comfortable to work.

There are jacks various types by drive type.

Mechanical type, in which lifting occurs by pressing the handle. These jacks are intended for infrequent use. Such devices are compact, but require physical effort.
Hydraulic type. Similar to the previous one, but requires less effort. The wheel rises due to the pressure created by the working fluid. Great for frequent use.
Pneumatic type. The device operates using compressed gases. Gas cylinders are required for use. The gas creates pressure, the chamber increases in size, and the car begins to rise. No physical effort is required.

You will find detailed information on how to make it yourself in the material from our specialist.

Our expert will tell you in detail how to make a working one with your own hands step by step.

You can read information about making it yourself in the article by our specialist.

According to the operating principle, jacks are divided into screw, rack and pinion, pneumatic and hydraulic. Jacks can be stationary, mobile or portable. Homemade devices Most often they are portable, as they are small in size. Stationary jacks are intended for large loads and are rarely of interest to car owners.

How to make a car jack with your own hands?

DIY hydraulic jack

Hydraulic jacks should be given Special attention, since they have the highest load capacity, which is important when working with trucks or SUVs. It is possible to manufacture hydraulic jacks with different sizes and characteristics. Modern mechanisms They are used not only in service stations and auto repair shops, but even in the oil refining industry. The device can operate in both horizontal and vertical planes.

The main load-bearing elements of the device: a housing, a working fluid (most often it is oil) and a retractable piston. The body can be short or elongated. At the same time, it is made of hardened steel so that the structure can withstand the required level of loads. The housing serves as a guide cylinder for the piston and a reservoir for the working fluid.

The lifting device and the retractable cylinder are located in the housing openings. The descent is carried out by turning the T-shaped handle. The equipment is equipped with polyamide wheels, ensuring maneuverability. The extended body is designed for heavy-duty vehicles.

Hydraulic lifting mechanisms are the most common and convenient, so let's start with them. The manufacture of a hydraulic jack is as follows. You will need a welding machine, a hacksaw, an angle saw Grinder with metal disc, steel profile for construction.

Hydraulic jacks come in standard, trolley, bottle, hybrid, toe and diamond jacks. The manufacturing process of a conventional hydraulic jack is described in detail below. There are many drawings on the Internet from which these mechanisms are assembled.

First, a support platform for the mechanism is created. A steel rectangular profile measuring 50 by 50 millimeters is suitable. It is necessary to cut 4 parts 300 millimeters long from the profile. Lay these parts with the side walls facing each other and weld the joining seams from the bottom and top.
Make stands and stops. Saw off 2 parts from the profiled pipe. The length of the parts is calculated relative to the maximum stroke of the rod, then the height of the jack and the support platform is added to this. The stop is made of the same material. Its length is equal to the width of the support platform. The stop and the posts are connected by a weld, and a U-shaped structure is welded to the base.
Manufacturing a removable stop that can move along guides and apply pressure to the workpiece. It is made from several pieces of steel strip one centimeter thick. The length of the parts should be less than the distance formed between the posts. The resulting parts are connected in several places by welding. When installing the block on the press frame from a hydraulic jack, it is necessary to select 2 bolts with washers and nuts and connect the resulting plates to the block so that they are located on both sides of the racks. If necessary, you can reduce the distance between the moving stop and the upper beam of the structure when installing an intermediate square profile.

When manufacturing a rack jack, it is important to take into account that the stability of this structure is affected by the strength of fixation and the quality of the supporting platform. It is important to assemble the mechanism in such a way that the product does not move out during operation. The force applied when lifting loads depends on the maximum possible mass.

The process of making a rack jack is quite simple. You need to take 2 rack pipes and a welding machine. The pipes must be welded in such a way that they resemble a truncated pyramid. Next is taken steel sheet 5 mm thick. The upper and lower bases of the mechanism are made. A hole is made in the upper part, into which a nut must subsequently be welded. A hole is also made in the lower base. Next, a mechanical rod is inserted there for rotation.

To make the mechanism, it is better to use parts made of hardened steel. If you additionally attach a metal cable, the rack and pinion jack can, if necessary, replace the winch. The average carrying capacity of such a product will be from 5 to 20 tons.

DIY rolling jack

A rolling jack is easy to make, using as a basis a bottle unit with a pick-up height of about 23 centimeters and a channel of 10 and 12 millimeters. The bottle jack is the simplest mechanism of this kind. Despite this, it is used for repairing freight vehicles. The operating principle of the jack is based on the use of several working rods. The mechanism is based on a piston.

Lifting occurs using a lever, which is driven by a hydraulic cylinder. A rack is created from a 12-millimeter channel, and a lifting lever and base are made from a ten-millimeter channel. Rollers from a conventional washing machine are installed at the front. The cup is taken from a car bumper, and the braces are created from a 20 mm bar.

As a result, the operating principle of a rolling jack is similar to a bottle jack, but the axis of the working cylinder in this mechanism is located in the horizontal axis. The piston is not directly combined with the pickup. This mechanism received the name “rolling” due to the fact that in appearance it resembles a cart on wheels rolling on a flat surface.

When the lever is raised, the jack moves under the load (car). The mechanism is driven by touching the lever and lowered by turning the valve screw. If the car needs to be lowered, the tubular handle is mounted on the valve screw. The partition then fits into its groove. The screw rotates with the handle, relieving pressure in the working cylinder.

A screw jack consists of: a base, a lower and an upper arm, a stop and a screw mechanism. A metal base (assortment) is taken, having a cross-sectional area of 2.63 cm square. 4 through holes are drilled, with a diameter similar to the diameter of the pin. It is advisable to attach the base to a wider removable platform. Next, the upper and lower arms are made from a metal base.

The shaft is made of metal rod. The diameter of the rod is 12 millimeters. There should be a thread at one end, and a retainer at the other, attached to the shaft with a pin through through hole. An axis is made around which the shoulders rotate. The axles on both sides are pins with flat cylindrical heads, secured with cotter pins. A through hole with a diameter of 10 millimeters is drilled in one of the stops, and in the second internal thread. The clamp acts as a fastening of the shaft on the rotation side and transmits torque to the shaft.

The screw jack can be manufactured in three different variations: with trapezoidal thread, diamond-shaped, lever-screw.

More detailed information about positive and negative aspects you can read in the article by our author.

It is relatively easy to make a jack from an air spring with your own hands, given that this type of unit is a very interesting device. Pneumatic jacks are indispensable when it comes to precise installation. When working on uneven or loose surfaces such lifting mechanism irreplaceable. A rubber-cord flat shell made of reinforced fabric is the basis of the device. The shell expands when compressed air is supplied. The device is also quite complex in terms of design.

So, to make the mechanism you will need following materials: an old cushion from a truck, a bolt, a ball that can act as a bearing, a wheel bolt from a VAZ, a chamber fitting and a drill.

You need to screw a bolt into the hole of the pillow. Before this, you need to drill a hole in the bolt that will be occupied by the fitting. It is also necessary to make a hole in the VAZ wheel bolt. It will act as a valve. The elements are connected. A ball is placed in the existing outlet, blocking the passage of air during operation. A pump is required to use the device. The jack will be located under the bottom of the car. You will also need wooden block, resting against the car.

DIY electric jack

It is not difficult to make a homemade jack for a car with your own hands, if we are talking about mechanical devices, working on the physical efforts of users, compressed air and working fluid. It is somewhat more difficult to make an electric jack with your own hands.

Electric lifting mechanisms are the result of the synthesis of mechanical moving components and an electric drive. Such a jack can be powered from the vehicle's electrical network. You can connect the device via the cigarette lighter.

The starting materials for manufacturing may be different. Motors for window lifters are suitable (as an example, you can take a motor from the “ten”). The drive and cables must be removed, leaving only the motor and gearbox. You will need a head whose tetrahedral side is equipped with edges of 7 millimeters. The base can be a regular screw diamond jack.

Our task is to create an electric drive so that there is no effort when using it. The fastenings are made of steel strips. The fasteners must be trimmed and given the desired configuration, and then attached to the gearbox. The mount and the head on the gearbox are welded to the device. The device can be controlled using a button from the window lifter mechanism.

Device comparison

Screw jacks with trapezoidal threads maintain a simple design, low weight and ease of operation with a high load capacity. The rhombic design of such mechanisms is distinguished by the presence of a long drive handle, which reduces the required effort to lift the load. The design is also lightweight and has good stability.

Lever-screw lifting mechanisms are distinguished by their large lifting heights and small dimensions.
Post-screw jacks have high stability and rigidity.
Rack-type structures are distinguished by their ability to be used in different directions and ease of operation, as well as a high lifting force.
Bottle hydraulic jacks have the most simple design and high rigidity of the connection during operation. The effort required for lifting is minimal.
Rolling jacks are stable, have a small initial installation height and considerable rigidity during operation.
Electric jacks perform best in extreme conditions, do not require physical effort and have high accuracy and sustainability.
Pneumatic lifting mechanisms provide convenient and reliable use due to their large bearing surfaces. They are also distinguished by their quietness and good operating speed, high efficiency and unpretentiousness.

“From the presented material you will learn how to make a garage rolling jack for lifting a car with your own hands, and we will also look at drawings, photos and videos of the design. Car enthusiasts know very well that when operating a car, they often have to jack it up to change tires from summer to winter and vice versa, and there are also punctures in the inner tube and to repair it it is necessary to remove and disassemble the wheel. “Curious things” also happen with tubeless tires. Fiddling with a standard car jack is not always convenient, as they say, “bent to death))” For this reason, a rolling jack was invented, which is very easy to operate and maintain.

The design includes a hydraulic jack 2 t “bottle” base and a lifting lever with a rubber gasket “cushion”. For ease 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 to prevent slipping while jacking up the car.

Lever arm has a unique shape, all dimensions and angles are given in the drawings. The lift is carried out 50 cm from the floor level, which allows you to replace both wheels of the car without reloading the jack. There is a rubber cushion at the end of the lever

The lifting height of the lever is 50 cm.

The jack is placed on a movable platform.
