Do-it-yourself rolling jack drawings sketches. Reliable homemade jack. Types of jacks and their features

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 ensure safe operation, this value must exceed the weight of the 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 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 device is performed by electricity. The advantages of the device are undeniable, but you need to connect it to the outlet.

Security measures

Despite the fact that the inflatable jack is one of the most elementary in terms of operation, its use requires certain precautions.

To prevent the unit from flying out from under the car, it must be installed correctly. Before installing a new pneumatic device, it is advisable to deflate it once without load, after which it descends and fits itself accordingly. To protect the jack from damage, it is better to lay a rug on the floor.

For the manufacture of the working chamber of the device, materials based on PVC are suitable. At sub-zero temperatures, this design hardens and becomes rough. According to experts, the optimum operating temperature is 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.

The problem of lifting loads of large masses in front of mankind has been standing for a long time. In recent years, jacks have been increasingly used to solve it. 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?

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.

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. A sufficiently high pressure is created, 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 carrying out repair work on heavy equipment. For example, it can be a bus or a heavy vehicle.

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 design options.

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 according to the following principle, which allows you to lift 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 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 the check valve enters the slave 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

The most common 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 a 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 of various designs, we can come to the following conclusion.

For use with a passenger 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.

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!

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 someone needs templates written with a higher resolution, write to me and send them with pleasure (the quality of the proposals 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 mechanization of work in various sectors of the 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 of a 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.

Maintenance points are 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. A universal mechanism that can be used in any life situations when it is necessary to lift a load.

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)

I was prompted to take up such "creativity" by the statement about the "hard" work of copyists of other people's homemade products. Let's call it "pen test".
To complicate my task, I completed it from a video plot.

I must say right away, may the author forgive me and let him himself look for his creation on the Internet. I present to your "court" MY "creation".

Each motorist, with the purchase of a car, acquires a jack for maintenance. Jacks are different, both purely mechanical and purely hydraulic. But all of them have a major drawback, which is ease of use. It is impossible to install a jack under the car without bending over in "tri-doom". There are more advanced ones for stationary use, but the cost of such "rolls over". That's about such a jack and will be discussed.
The author of the homemade product connected two types of jacks together. Here's how he did it.

Design features.
For his design, the author used a ready-made hydraulic jack, making a fixture for it. The whole structure consists of a thick-walled channel at 80. made from a whole billet. The bends of the structure were achieved by cutting the side walls and further welding. From the photo you can clearly see the device of the support rollers (wheels), I don’t see the point in dwelling on them. For direct support on the car body, a rubber support is fixed, it can be taken from the support pads of the springs, the engine ... having finalized to the desired size.

To install and fix the jack, a metal plate is welded (screwed) onto the lower channel, having the size of the jack base and a thickness of about 5 mm. The main focus will be on the channel.

To fix the jack, two 8-10mm holes were drilled in its base, and two guide pins were installed in the base of the welded platinum for the jack. That allows you to securely fix the jack and at the same time freely remove it.
A piston pin from the car was welded onto the main rod of the jack, cut off to fit the inner width of the channel. This finger rests on the movable part of the device and so that the jack cannot "slip", limiters are welded on both sides of the finger inside the channel in the form of two metal plates with a thickness of at least 8-10 mm. In this case, the finger should rotate easily there.

For rigidity of a design "kerchiefs" are welded. In order not to increase the weight of the device, they are not made of solid metal. A handle is also welded for ease of use.

Having rolled the device under the car, you, as usual, use the handle to start lifting the main rod of the jack and thereby set the lifting arm in motion.

Due to the enlarged lifting lever, it is possible to completely lift the entire side to be lifted. Both wheels are not supported.

That's probably all about the features of the manufacture of this design.

To give a homemade "look", it must be painted.

What do you need to make such a "rolling" jack:
0. Head.
1. Ready hydraulic jack.
2. Thick-walled channel at 80, around 1.5m.
3. Metal plates with a thickness of 5 to 10mm, 150-200 cm square.
4. Metal "kruglyash" with a diameter of 12-16mm. 1-1.5 meters.
5. Car piston pin.
6. Rubber "cushion".

Tool
1. "Bulgarian"
2. Welding.
3. Locksmith tool.

Before you get to work and make a pneumatic jack with your own hands, you should know more about such an auxiliary tool.

An inflatable jack is the most elementary option of all analogues. The convenience of such a tool is that it is unpretentious in use, it does not need a flat area. Having such a jack in the trunk and once in a swampy loose area, you can not be afraid to use it. In addition, with the help of it you can not only replace the problematic wheel, but also get out of the mud. Working with it, no special physical effort is required, so it is even used in carrying out rigging work.

Working principle of pneumatic lift

The main working element of this jack is the rubberized pillow. It is made of a special durable material so that the unit can withstand loads in the range of 4-5 tons.

To power such a tool, it is placed under the bottom of the machine and connected to a pump or other air source, such as a compressor or a compressed gas cylinder. There are models that are especially popular, since their work can be carried out, one has only to connect such a jack to the exhaust gases of a car. They do not need any additional equipment. Such structures are called air jacks or pneumocrates.

For such a device, a hose is enough to connect the exhaust pipe and the jack itself, and then turn on the engine. It takes literally 2 minutes for the tool to do its job. In this version of the device, there are no complex mechanisms that carry out work due to pneumatics.

Technical characteristics of pneumatic jacks

There are three main points on which such a device is evaluated:

1. Load capacity. For the tool to be safe to use, this indicator must exceed the mass of the car itself. If the car is a passenger car, then the carrying capacity should be 1.5-2 tons, and if the car is of the Gazelle type - 2.5-3 tons.
2. Pickup height. This parameter should be paid special attention if the car has a small ground clearance. You should be interested in this moment in the case of frequent car stuck in the mud. It is best if this characteristic is within 10 cm.
3. lift height. For pneumatic models, this figure does not exceed 50 cm. But in fact, this is enough to cope with the replacement of wheels. If you use a jack, which is used for rigging, and it, in turn, is connected to compressors, then this characteristic will be greater - up to 70 cm.

In any case, when choosing a jack, you should be guided by a personal car and the conditions in which it is most often located.

How to make a jack with your own hands

You will need the following items:

• an old pillow from a truck;
• bolt of the appropriate diameter;
• a ball that can be freely located in the bolt;
• wheel bolt from Zhiguli;
• chamber fitting;
• drill.

From these components, a structure is assembled. A bolt is screwed into the pillow hole, focusing on the existing thread. In advance, a hole should be drilled in it into which the chamber fitting will be inserted.

The role of the valve will be performed by a wheel bolt from the Zhiguli, in which a hole should be made. Now these elements need to be connected. But before doing this, a ball is placed in the existing outlet so that in the process of work it can close the hole, then the air will not come out.

To use such a device, you will need a special pump. The jack is installed under the bottom of the car. In such a device, you will need to use a small wooden block, which will rest against the car. If desired, a cart with wheels can be attached to the bottom, then it will be a rolling jack.

There is one inconvenience of such a homemade device. The pillow from the truck is quite large. Therefore, if the car has a low landing, then it will constantly have to be raised to substitute the jack.

Lifting Power: Highlights

There are several options for how a jack can raise a car:

1. Pneumatics. In this variant, the lifting of the load is carried out using the power of compressed air. Such models work both from equipment and from the exhaust gases of the car themselves. Air enters the chamber, and that, in turn, begins to increase in volume, due to which the transport rises. The convenience of using such models is that no special efforts are made, and with a compressor, the process takes only a few seconds.
2. Mechanical. To use this analogue, it is necessary to make twisting movements with the handle or use another similar method. Such jacks are quite affordable, besides they have small dimensions.
3. Hydraulic. The principle is similar to the previous option, the only difference is that in this case less effort will be expended. This is due to the fact that the design of the device contains a liquid that ensures the expulsion of the plunger with the load due to the resulting pressure. This option has a long service life.
4. Mechanical with electric drive. In this embodiment, all the work for a person is done by electricity. The amenities here are undeniable, but only as long as there is food. As soon as the light is turned off, you will have to work in the same way as ordinary mechanical ones, with the only difference being that more effort will be needed.

Depending on the scope of the jack, the required model is selected.

Despite the fact that the pneumatic jack is the easiest to use, there are some nuances in its use. To avoid the tool flying out from under the machine, it must be properly laid. Therefore, before using a new device, it is better to empty it once, after which it descends and folds properly by itself. In the process of work, it will be useful to cover the surface of the floor and the jack with some kind of rugs. This will protect the instrument from damage.

The materials for the manufacture of the chamber are taken on the basis of PVC, and he, in turn, becomes quite rough as soon as frost appears on the street. It is optimal to use until the thermometer shows -10, then operation becomes difficult.

The convenience of such a jack is that with its help you can raise the car from almost a minimum height. And if there is no desire to spend money, then you can always do it yourself.
