A 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:

1. load indicator. To provide 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.
2. Pickup height. This aspect plays an important role if the car has a small ground clearance. The optimal indicator is a value of at least 100 mm.
3. 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 the practical implementation of this device, a special pump is required. The inflatable jack is installed under the bottom of the vehicle. For safety, it is advisable to use a wooden stand that 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 any 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 have a long service life.

A mechanical jack with an electric drive is powered by mains power, all the main work of the fixture is done 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 temperatures, this 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 quite a lot of 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.

Having at hand a drawing - a screw jack, we make it with our own hands from steel bent equal-shelf channels GOST8278-83.

In the figure, the types of sizes of the assortment used are highlighted in blue rectangles

The screw jack consists of the following parts:
Base
Lower shoulder
upper shoulder
Emphasis
screw mechanism

BASE

Let's make from a range with a cross-sectional area of ​​\u200b\u200b2.63 (cm²). We drill four through holes with a diameter equal to the diameter of the pin. When drilling, strictly maintain the center distance between them. If necessary, the base can be attached to a wider removable platform.

LOWER SHOULDER

We will produce from a range with a cross-sectional area of ​​\u200b\u200b1.99 (cm²) by analogy with the base.

UPPER SHOULDER

Let's make from a range with a cross-sectional area of ​​\u200b\u200b2.28 (cm²) by analogy with the lower shoulder.

UPOR

Let's make from a range with a cross-sectional area of ​​\u200b\u200b1.99 (cm²) by analogy with the upper shoulder.
From above, we fasten the rubber gasket.

SCREW MECHANISM

1. Shaft - screw. We will make from a metal bar with a diameter of twelve millimeters. On the one hand, there is an M12 thread, on the other, a retainer, which is attached to the shaft with a cotter pin through a through hole on the shaft.

2. Axis - emphasis. Relative to which the rotation of the lower and upper arms occurs.

The axles on both sides are pins with cylindrical flat heads, which are attached to the axle with cotter pins.

A through hole with a diameter of ten millimeters was drilled in one stop, and a hole was cut in the other. internal thread M12.
3. Retainer. Fixes the shaft from the side of its rotation and provides the possibility of transmitting torque to the shaft.

Performance characteristics of a do-it-yourself screw jack.

Good afternoon everyone. I have a diamond jack, I lost the handle from it, it was made in the form of a hook. Lifting a car with such a jack without a handle is not very convenient. In two or three stores I asked about a pen, they didn’t have one, it was decided to come up with something else. Therefore, it was decided to modernize this jack, so to speak. Moreover, it is already necessary to put summer wheels, winter has passed.

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

Here I sawed off the ear.

Now we need to find, or rather pick up the head, which we will weld instead of our ear. So I picked up such a head from myself, you don’t need to do anything extra with it, you just need to weld it well.

Now we take welding machine and weld the head.

It turns out like this.

After welding, I turned this place a little, I did not turn it too much, so that a little iron remained 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's all, if this article helps anyone, I will be very happy. The idea was spied on by Alexei from Tambov.

The most necessary things that every motorist should have are a jack, wires for lighting, 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 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 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.

One of the most popular types of vehicle lifts is the roll-on type. 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. You also need a welding machine and an old bottle hydraulic or conventional pneumatic jack. 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 solution. 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 stage is the supporting structure, which is made of a profiled square tube. It is desirable that its thickness be at least 10 mm. We use an old bottle-type hydraulic jack as a basis. It is worth paying attention that even in this case, you will need a lot of metal profile, welding, as well as 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 huge selection 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. 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 competently, then the output will be a reliable 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.

The problem of lifting loads of large masses in front of mankind has been standing for a long time. AT last years to solve it, jacks were increasingly used. The hydraulic jack stands apart in this row. He is able to lift 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 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 so complicated as it might seem at first glance. The main elements are the body, pump, plunger, screw with lifting heel. The hydraulic jack is most often made of hardened steel. In this case, a special oil with high viscosity indicators acts as a working fluid. Conventional motor oil will not work in this situation.

Hydraulic jack device.

It is worth considering this when developing a device. Usually it is the body that 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 protective 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. At the same time, the lifting mechanism and a special retractable hydraulic cylinder are able to raise the working platform. Created enough high pressure, which allows you to lift loads of various masses. The body of such a device can be both short and elongated. The second option is most often used when conducting repair work heavy equipment. For example, it can be a bus or a heavy vehicle.

Main characteristics

Device screw jack.

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 a practically incompressible working material. It's about hydraulic oil. From this we can conclude that smooth running cannot be avoided in the work, that is, raising and lowering. At the same time, the load can be fixed at almost any height. It is worth noting that such devices have a fairly high efficiency, which is equal to 80%. At the same time, the lifting capacity of the mechanism can reach 200 tons. Of course, such powerful aggregates will not be considered in this paper, but the reader should be aware 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 are talking about carrying out repair work with cars of low landing.

The device is a simple homemade jack.

There are, of course, disadvantages to hydraulic jacks. The main one is that it is very difficult to adjust the lowering height in such mechanisms. In order for the device to be constantly in working condition, it has to be checked. Here it is necessary to monitor the oil level, the condition of the valves, gaskets and seals. If necessary, these elements must be replaced. Sometimes it can be difficult to transport jacks. They must be stored and transported only in an upright position.

Otherwise, it is likely that all the liquid from the tank 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 think about alternative solutions Problems. Some people buy mechanical jacks because they are several times cheaper, while others make their own hydraulic jacks.

Hydraulic press manufacturing

Hydraulic press device.

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

The first node in this design will be the support platform for the jack. Since you will have to work with quite impressive weights, you need 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 truly of the highest quality and reliable.

For work, you can use both a square and a rectangular profile.

Drawing pneumohydraulic rolling jack.

Here the choice depends directly on the capabilities of a person and on what he has at hand. Further, these parts of the structure are laid base to each other. In this case, it is worth making as many welds as possible. This will achieve the required rigidity. You need to weld the elements to each other both from below and from above. In order for the design 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 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 ​​\u200b\u200btogether. 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 be the result.

The emphasis must be made of the same metal from which the racks are made. Then all the elements are connected to each other. The result is a U-shaped design. In order to ensure the perpendicularity of all structural elements, it is necessary to make a very simple fixture. 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 °. Then all these elements are welded together. Everything is quite simple, but at the same time the design turns out to be really as reliable as possible.

The load capacity of the screw jack is calculated by the formula.

In order to further make it more convenient to work, this device should be equipped with special clamping mechanisms. This will 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. 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 uprights.

It should be noted that the components of the stop are interconnected 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 design. 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 rigid as possible. If it is necessary during the execution of work to reduce the working stroke of the hydraulic jack rod, then it will be necessary to make the distance between the stop and the steel part of the structure, that is, its beam, 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.

Summarizing

So, the above revealed the advantages of hydraulic jacks. As you know, this device can be used not only for its intended purpose. For a garage-type press, it is quite appropriate. The hydraulic jack in this case becomes one of the 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 body is made of hardened steel. Do not 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 a press with their own hands.

Making a homemade comfortable car jack from improvised materials is very simple! in the video a short overview, if you are interested in something about this invention, ask questions. and offers!

A jack is used to raise the car for repair or replacement of a wheel. They come in 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 designs.

The principle of operation of the hydraulic jack

This device is simple and reliable.

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

A jack is used to raise the car

The hydraulic jack works following principle, which allows you to lift a car that has a weight of 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 details are made of high quality durable materials, then there is nothing to break.

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

The working cylinder, the rod of which raises the car, is large in 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 through check valve enters the working cylinder and lifts it. Strengthening is created due to the difference in the cross-sectional areas of the cylinders.

Do-it-yourself rolling garage jack | Blueprints

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

A non-return valve is used to prevent oil from flowing back into the reservoir. Fluid can only flow through this valve in one direction.

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

The principle of operation and its device are indicated in the diagram.

Hydraulic jack design

Two types are used to lift cars: bottle and rolling.

Hydraulic bottle jack

So, a bottle-type hydraulic jack.

It consists of a vertical body of 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 lifting height. The two cylinders are interconnected through a check valve.

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

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

The design of another variety - a rolling hydraulic jack, differs only in the location of the cylinders and the presence of a large platform on the rollers.

Lifting 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. This lever has a metal pin.

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

Despite this, safety measures during work must always be observed. Be sure to fix the car with the parking brake, the included transmission gear and the installation of stops under the wheels.

When working under a raised vehicle, always install a safety stand. These measures will ensure the safety of the working person. You can see the detailed design in the drawing.

Rolling hydraulic jack

Jack maintenance and repair

Most frequent malfunction is the leakage of the working fluid through the seals and stuffing boxes.

The leak must be pinpointed and repaired. It is necessary to use only special oil-resistant seals and gaskets. Valve failure may be due to clogged or broken springs.

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

But you need to store them only in their original state, so that the stem is completely hidden in the body, this will protect 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, you need to change the working fluid. This is simple procedure. There is a filling hole on the body, closed with a screw plug.

Through this hole, draining and filling with new oil is performed. After that, it is necessary, without load, to fully raise and lower the stem several times. This will release any air that may have entered the system.

This is a reliable device that allows you to lift a load of several tens of tons.

It is not complicated. In terms of load capacity, hydraulics are far ahead of other types of designs. But, unfortunately, there are also disadvantages:

• Big weight, really big, 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 various designs one can come to the following conclusion.

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

Good holiday cards for every day

Technique: Quilling 1.

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

Of course, it is better to use a ruler with circles. If you additionally make a decorative braid, it must be wiped until each edge.

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

Rollins get the shape of a flower petal.

If you need decorative embroidery.

Among the flowers

Collect the flower. In beautiful flowers, all flower petals are the same. I use this template to properly edit flower petals.

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

But the frog strangled me and I wanted to keep the flower together. So I drew the diagram myself. But the flowers come with different flower petals, and then come to me too lazy, but not to draw the same way for all the 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 the template for colors 3, 4, 6 and 12 roosters!!!

Therefore, print the template and pick up the flower on the template.
If the core is above the petals, then we are only leaning 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!

And then we glue the core.

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 put in a flower.

twenty fifth

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

twenty sixth

The result is a fairly durable flower and can be used for both bulk 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 templates for 12 petals and, in addition, you can place flowers from a needle.

twenty-eighth

twenty ninth

I put foam under the template.

thirties

thirty first

In a handmade flower vase (http://stranamasterov.ru/node/18967) I made all the flowers using the template for 10 and 6 petals:

thirty second

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

Not only can you use these patterns to create flowers, but you can also tie mandala, wreaths, snowflakes, and more.

Hope this is all helpful! If anyone needs templates written with more high resolution, write to me and send them with pleasure (the quality of the offers has been reduced according to the rules of the site).

I wish you all creative success!!!

A hydraulic jack is a stationary, portable, mobile mechanical device for lifting any object, located under it, which allows you to do without auxiliary structures, hoists. The mechanism runs on mineral oil, which, by moving the differential piston of the pump, lifts the load. It 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), with a small effort working with it, high efficiency, smooth lifting, and structural strength.

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

Types of jacks

They are produced in various modifications: bottle, rolling, rhombus, two-level, low-lift toe. They differ in designs, in type of drive.

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

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

The support area is located on the lever, which is raised by the working piston. The pickup height allows you to lift a car of any brand weighing up to three tons.

It has varieties: scissor, with a two-piston displacer cylindrical shape, elongated.

Jack device

The main parts of the mechanism capable of lifting and lowering the 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, lifting the cylindrical part up. As a result, the load rises. A device designed to maintain pressure at the required level consists of suction and discharge valves.

The suction one does not allow the oil to return from the cylinder to the reservoir, the discharge one - to leave it. By unscrewing the screw, the pressure decreases, the load rises to a predetermined place.

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

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

Vertical, to prevent oil leakage, are transported standing up. They require regular monitoring of the oil level, condition of 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 the load.

The most common application in the prevention, repair of automotive equipment.

Items Maintenance in most cases equipped with rolling jacks. Often used in construction and installation works, laying gas and oil pipelines, an indispensable assistant in rescue operations. Universal mechanism, can be used in any life situations when a load needs to be lifted.

Do-it-yourself screw jack drawing

Having at hand a drawing - a screw jack, we make it with our own hands from steel bent equal-shelf channels GOST8278-83.

In the figure, the types of sizes of the assortment used are highlighted in blue rectangles

The screw jack consists of the following parts:
Base
Lower shoulder
upper shoulder
Emphasis
screw mechanism

BASE

Let's make from a range with a cross-sectional area of ​​\u200b\u200b2.63 (cm²).

We drill four through holes with a diameter equal to the diameter of the pin. When drilling, strictly maintain the center distance between them. If necessary, the base can be attached to a wider removable platform.

LOWER SHOULDER

We will produce from a range with a cross-sectional area of ​​\u200b\u200b1.99 (cm²) by analogy with the base.

UPPER SHOULDER

Let's make from a range with a cross-sectional area of ​​\u200b\u200b2.28 (cm²) by analogy with the lower shoulder.

UPOR

Let's make from a range with a cross-sectional area of ​​\u200b\u200b1.99 (cm²) by analogy with the upper shoulder.

From above, we fasten the rubber gasket.

SCREW MECHANISM

Shaft - screw.

Reliable homemade jack

We will make from a metal bar with a diameter of twelve millimeters. On the one hand, there is an M12 thread, on the other, a retainer, which is attached to the shaft with a cotter pin through a through hole on the shaft.

Axis - emphasis. Relative to which the rotation of the lower and upper arms occurs.

The axles on both sides are pins with cylindrical flat heads, which are attached to the axle with cotter pins.

A through hole with a diameter of ten millimeters was drilled in one stop, and an M12 internal thread was cut in the other.

3. Retainer. Fixes the shaft from the side of its rotation and provides the possibility of transmitting torque to the shaft.

Performance characteristics of a do-it-yourself screw jack:

Hmin = 65 (mm)
Hmax = 312 (mm)
Pmax = 2000 (kg)
