A jack is used to lift the car for repair or wheel replacement. They are different designs... The most common are mechanical and hydraulic. In this article, we will consider in detail the principle of operation and the device of a hydraulic jack, as well as various options constructions.

Working principle of a hydraulic jack

This device is simple and reliable.

If you follow the storage and operating conditions, then it will serve you for a very long time.

A jack is used to raise the car

The hydraulic jack works according to the following principle, which allows lifting a car weighing several tons, and sometimes several tens of tons.

The device is not complicated - these are two communicating vessels of different diameters filled with liquid and several valves. As you can see, everything is quite simple, and if all the parts are made with high quality from durable materials, then there is nothing to break.

Only rubber piston seals and cylinder seals are subject to wear.

The working cylinder, the rod of which raises the car, is of large diameter, but the main cylinder has a diameter several times smaller.

This is the principle of operation of the entire device. The master cylinder is actuated by a lever, oil enters the slave cylinder through the check valve and lifts it. Reinforcement is created due to the difference in the cross-sectional areas of the cylinders.

Full stroke of the main, provides a slight movement of the second. The difference in stroke between the two cylinders is proportional to the difference in their diameters. Thanks to this, a person, without making serious efforts, can lift five, ten, and several tens of tons.

To prevent oil from flowing back into the reservoir, a check valve is used. Liquid can only flow through this valve in one direction.

There is another valve that opens manually, it is necessary in order to bypass the fluid back and lower the raised car to its original state.

The principle of operation and its structure are shown in the diagram.

Hydraulic jack design

There are two types of vehicles used for lifting: bottle and rolling.

Bottle type hydraulic jack

So, a bottle type hydraulic jack.

It consists of a vertical body with a large diameter and a small cylinder adjoining it, to the stem of which a removable lever fits. The body is mounted on a support platform, it often has a screw extension in the stem, which is necessary in order to increase the lift height. The two cylinders are interconnected through a check valve.

The body has a reservoir to store the stock oil and a bypass valve to lower the stem of the bottle hydraulic jack.

All parts must be made of durable alloys, so they experience significant stress and are protected from corrosion.

The design of another type - a sliding hydraulic jack, differs only in the arrangement of the cylinders and the presence of a large platform on the rollers.

The lifting of the car with the help of a hydraulic rolling device is carried out not by the rod itself, but by the lever connected to it. A metal penny is installed on this lever.

The rolling structure is more stable than the bottle structure and the likelihood that the raised vehicle will move and fall off the support is much less.

Despite this, safety measures during work must always be followed. It is imperative to secure the car with the parking brake, the transmission gear engaged and wheel chocks.

Always install a safety stand when working under a raised vehicle. These measures will help to protect the working person. You can see the detailed design in the drawing.

Maintenance and repair of the jack

The most common failure is fluid leakage through seals and seals.

It is necessary to accurately locate the leak and repair it. Only special oil-resistant oil seals and gaskets should be used. Valve failure can be associated with clogged or broken springs.

It is necessary to disassemble, clean and replace defective parts.

But they need to be stored only in their original state, so that the stem is completely hidden in the body, this will save it from corrosion. In addition, the bottle type must be stored vertically so that the working fluid does not leak out. Once every few years, it is necessary to replace the working fluid. This is a simple procedure. The body has a filler hole closed with a screw plug.

This hole is used to drain and fill with new oil. After that, it is necessary, without load, to completely raise and lower the stem several times. This will release air that may have entered the system.

it reliable device, allowing to lift a load of several tens of tons.

It is not difficult to arrange. In terms of lifting capacity, hydraulics are significantly ahead of other types of structures. Unfortunately, there are also disadvantages:

• Great weight, really heavy, several times heavier than mechanical competitors.
• Special storage conditions for the safety of the working fluid and the risk of corrosion of working elements. This is especially true of the bottle jack.
• inability to use at low temperatures.

  The hydraulic fluid thickens at temperatures below -25 degrees, the elasticity of the seals is lost, and the risk of failure increases.

After analyzing the advantages and disadvantages of various designs, you can come to the following conclusion.

For use with by car, weighing up to two tons for the necessary road repairs (wheel replacement), a compact mechanical jack is sufficient. However, for lifting a large and heavy machine, it is better to consider using hydraulics.

Technique: Quilling 1.

If you want a beautiful and "real" flower, you need to make the same flowers.

Of course, it's best to use a ruler with circles. If you additionally make decorative braiding, it must be wiped off until every rib.

Take a tape of paper, a ruler, and a rolling and rolling roll tool.

Rollins get the shape of a flower petal.

fourth

If you need decorative embroidery.

Among the flowers.

Collect the flower. In beautiful flowers, all flower petals are the same. I am using this template to edit the flower petals correctly.

Of course, there are special rulers that sell in the store and are certainly very convenient, etc.

But the frog strangled me and I wanted to keep the flower together. So I drew the diagram myself. But flowers come with different flower petals, and then they come to me too lazy, but not to paint the same for all options by hand.

So I made suggestions on my computer.

I work with these schemes and secrets.

The numbers indicate the number of petals in the flower. It should be noted that pattern 12 is very useful as it contains a pattern for flowers 3, 4, 6 and 12 roosters !!!

So print the template and take the flower on the template.
If the core is above the petals, then we only lean on the flower petals. Stretch the glue only at the ends of the petals, and it is advisable to leave the flower on the template until the glue is completely dry!

For a voluminous flower, you also need to make a sepal.

twenty third

And then attach it to the stem (I do this with glue).

twenty-fourth

And insert the flower.

twenty fifth

If the kernel is at the level of the petals, place it in the middle and then crush the flowers. And if the flower petals don't stick to each other, they lift the glue flower on each leaf to the center.

twenty sixth

It turned out to be a rather durable flower and can be used for both volumetric and chests.

twenty seventh

Also with the help of a template it is suitable for blooming flowers with several levels:
Fill 6 petals with a core, make two empty ropes and connect them to each other using the 12 petal templates and you can also place flowers from a needle.

twenty-eighth

twenty ninth

I put the foam under the template.

thirties

thirty first

In a handmade vase of flowers (http://stranamasterov.ru/node/18967) I made all the flowers using the 10 and 6 petal pattern:

thirty second

If the flower is well attached to the paper, then the template should be placed under the sheet and illuminated by a lamp under these sheets. You can also use glass and window (damage should only be vertical).

You can use these patterns not only for making flowers, but also for tying mandalas, wreaths, snowflakes, etc.

Hope this is all helpful! If anyone needs templates written with a higher resolution, write to me and send them with pleasure (the quality of the proposals was reduced according to the rules of the site).

I want all creative successes !!!

A hydraulic jack is a stationary, portable, mobile mechanical device for lifting an object, located under it, which makes it possible to do without auxiliary structures, hoists. The mechanism runs on mineral oil, which, by moving the differential piston of the pump, lifts the load. Is a means of mechanizing work in various industries National economy.

The hydraulic jack is distinguished by the ability to lift a large mass of cargo (from two to two hundred tons), a small effort working with it, a high efficiency, smooth lifting, and structural strength.

The disadvantage of powerful mechanisms is a large mass, the initial distance from the parking level of the lifted load, slow single movement of the piston, high cost.

Types of jacks

They are produced in various modifications: bottle, rolling, rhombus, two-level, low-grab hook. They differ in design, in the type of drive.

The bottle jack is used in various areas of the economy, it is distinguished by its simplicity of the device, convenient operation. It is used for lifting and lowering special equipment, cars, trucks. During construction, it is possible with its help to raise the building. The main condition is that the weight of the load being lifted must correspond to the lifting capacity of the mechanism specified in the instructions.

The rolling jack works on the principle of a bottle jack.

The support area is located on a lever that is lifted by a working piston. The pickup height allows you to lift any brand of vehicle weighing up to three tons.

Has varieties: scissor, with a two-piston displacer of cylindrical shape, elongated.

Jack device

The main parts of a mechanism capable of raising and lowering a load are: a lever - a crossbar rotating around an axis, a plunger - a hollow cylindrical rod.

Valves - shut-off and control valves for passing, shutting off, regulating the flow of hydraulic oil.

Oil storage, reciprocating movement mechanism inside the cylinder.

When the pump is running, hydraulic fluid fills the base of the cylinder, raises the cylindrical part up. As a result, the load rises. The device designed to maintain the pressure at the required level consists of a suction and discharge valves.

The suction does not allow the oil to return from the cylinder to the reservoir, while the pressure oil does not leave it. By unscrewing the screw, the pressure decreases, the load rises to the specified place.

Hydraulic oil has the property of non-compression, which affects the uniformity of raising, lowering, fixing the object at the desired height.

At the same time, lifting mechanisms have a low operating speed, difficulties in storage, movement.

Vertical, to prevent oil leakage, transported standing. They require regular monitoring of the oil level, the condition of the oil seals, valves (no hydraulic oil leakage).

A hydraulic jack is used in everyday life for all kinds of work, when it is necessary to lift a load.

The most frequent use in the prevention, repair of automotive equipment.

Items maintenance in most cases they are equipped with rolling jacks. Often used in construction and installation work, laying gas, oil pipelines, an irreplaceable assistant in rescue operations. A universal mechanism that can be used in any life situations when it is necessary to lift a load.

Mankind has faced the problem of lifting large loads for a long time. IN last years jacks are increasingly being used to solve it. The hydraulic jack stands alone in this row. It is capable of lifting really heavy loads with a minimum of effort. Hydraulics, since the emergence 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?

Design and its features

Of course, before starting work directly, it is imperative to learn more about the design of the hydraulic jack. In fact, it is not as difficult as it might seem at first glance. The main elements are the body, pump, plunger, screw with a lifting heel. The hydraulic jack is most often made of hardened steel. In this case, a special oil with high viscosity values \u200b\u200bacts as a working fluid. Regular engine oil will not work in this situation.

This should be taken into account when developing a device. Usually, the body is the main part of the 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 ensure 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. Lifting mechanism a special retractable hydraulic cylinder is also capable of raising the platform. Enough 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 conducting renovation works heavy equipment. For example, it can be a bus or a heavy vehicle.

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 car shop. We are not looking for simple ways and we will talk about how to make a homemade jack for a car.

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, sliding 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, this is one of the most optimal options... It is not so difficult to make a homemade jack for a car, let's see how. Let's start with the simplest.

Do-it-yourself rolling jack

One of the most popular types lifting devices car - rolling. It's not called that because it can be transported on wheels from one corner of the garage to another. The principle of operation is that when the vehicle is raised, the jack moves under the vehicle. 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 carrying capacity, the second is less problematic in terms of maintenance. The displacement of the rolling jack is possible in the presence of 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 construction material is quite costly. Unless, of course, you have half of the stuff in the garage that is there as junk.

Of the material, you need a channel with 4.5 mm walls and 7.5 mm thick shelves. Also needed welding machine and old bottle hydraulic or conventional Do not make the levers too long, 400-500 mm. But if it was done that way, you should think about making an additional stop. The advantage of this jack is that it is convenient to use. But at the same time, carrying it with you in the trunk is not the best solution. Ideally 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 large as possible. This can be achieved with additional stiffeners.

An important stage is the support structure, which is made of a profiled pipe. square section... It is desirable that its thickness is at least 10 mm. We use the old hydraulic type as a basis. It is worth noting that even in this case, you will need a lot metal profile, welding, and effort.

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

Buy or do?

Of course, you can make a homemade jack for a car. But it is worth doing this 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, rolling jacks of good quality are sold. They have good lifting capacity and are reliable, although they are extremely bulky and heavy. You can make a rolling stock. 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 here it is not difficult to make a mistake. For example, some welds, especially where the arm is bent, may burst, which in turn can cause 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 weekend and a lot of nerves and materials. But if you have a tool, and there is 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.

Good afternoon everyone. I have a diamond jack, I lost the handle from it, it was made in the form of a hook. It is not very convenient to lift the car with such a jack without a handle. In two or three shops I asked about a pen, they didn't have one, it was decided to come up with something else. Therefore, it was decided to upgrade this jack so to speak. Moreover, the summer tires have to be put on, the winter has passed.

So, we take the grinder and carefully saw off this eyelet, where it was necessary to put the hook-handle in order for the jack to spin.

So I sawed off the ear.

Now we need to find, or rather pick up the head that we will weld in place of our ear. So I picked up such a head at my place, you don't need to do anything with it, you just need to weld it well.

Now we take the welding machine and weld on the head.

It turns out like this.

After welding, I sharpened this place a little, did not grind too much, so that there was some iron left for hardness.

With such a head, it is easy to turn the jack and raise the car, it is especially convenient to turn it with a ratchet.

Yesterday I tried the jack in action, changed all four wheels, put on summer tires, it became just convenient and easy to work with the jack.

Well, that seems to be all, if this article helps anyone, I will be very happy. The idea was spied on by Alexey from Tambov.

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

Main characteristics

Screw jack device.

There are tons of options that allow hydraulic jacks to be used anywhere. They are unpretentious in terms of carrying capacity. An important point is the presence of a practically incompressible working material. We are talking about hydraulic oil. From this, we can conclude that it is impossible to avoid smooth running, that is, raising and lowering. Moreover, 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, in this work, such powerful units will not be considered, but the reader should know that they exist.

The initial lifting height should also be noted. This figure is better than that of conventional mechanical models. Loads can be lifted from virtually zero height. This is very convenient, especially when it comes to carrying out repair work with low-rise vehicles.

The device is the simplest homemade jack.

There are, of course, drawbacks to hydraulic jacks. The main thing is that it is very difficult to adjust the lowering height in such mechanisms. In order for the device to be constantly in working order, it must be checked. Here you need to monitor the oil level, the condition of the valves, gaskets and oil seals. These elements must be replaced if necessary. Sometimes it can be difficult to transport 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 flow 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 to the problem. Some people buy mechanical jacks as they cost several times cheaper, while others make their own hydraulic jacks.

Hydraulic press manufacturing

Hydraulic press device.

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

The first knot in this design will be the jack support platform. Since you will have to work with rather impressive weights, it is necessary to make the platform as reliable and powerful as possible. Do not forget about this nuance. It is quite difficult to achieve the desired result. To do this, you need to apply several stiffeners at once. Only in this way will the design be really the highest quality and reliable.

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

Drawing of a pneumohydraulic rolling jack.

Here the choice depends directly on the capabilities of the person and on what he has at hand. Further, these parts of the structure are stacked with the base to each other. In this case, it is worth making as many welds 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 an emphasis and stands. 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 \u200b\u200btogether. It is necessary to add to the height of the jack the value of the stroke of the rod, as well as the height of the platform. The resulting number will be the result.

The stop must be made of the same metal from which the racks are made. Further, all elements are connected to each other. The result is a U-shaped design. 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 °. Further, all these elements are welded together. Everything is quite simple, but at the same time the design is really the most reliable.

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

In order to further it was more convenient to work, this device should be equipped with special clamping mechanisms. This will allow you to fix the resulting triangle and avoid 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. For work, you will need to use a special metal cut. 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 should be noted that the component parts of the stop are connected to each other by welding. In this case, you should not save on electrodes. Only a good connection of all structural elements will make it possible to make a really high-quality structure. Now you can proceed to the installation of the hydraulic jack itself. It is fastened with two bolts of the same length.

It is worth making it as strong and tough as possible. If it is necessary to reduce the working stroke of the hydraulic jack rod during work, then the distance between the stop and the steel part of the structure, that is, its beam, will have to be made smaller. For this, an additional metal plate of the corresponding profile is used.

In order to make this distance less impressive, you can use additional removable inserts. They should be additionally marked in order to make the fastest possible tool change 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 a garage-type press, it is quite appropriate. In this case, the hydraulic jack becomes one of the the best options to create a similar 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. it perfect solution for every car enthusiast. The hydraulic body is made of hardened steel. Do not forget about quality materials for the piston itself. He will have to transfer the maximum load. Use only hydraulic oil as the working fluid. It has high viscosity values.

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