Hello everyone, in this article I want to tell you how you can make a simple and powerful, air, car jack, or you can also say a pneumatic jack for a car from sewer pipes.

For this we need 2 plugs for 110 mm, 1 sleeve for 110 mm, a small length of pipe for 110 mm, a glue gun, it can be replaced with ordinary glue of the moment type, but just sealant, hoses, a small faucet and 2 car nipples are suitable with nipple.

To get started, take the clutch, measure 2 cm from its side and cut it off.

We cut off the cut ends with a knife or sandpaper so that they do not cling. Next, in the center of this coupling, we drill a hole with a diameter of 10 mm.
  We take our spool, smear it with glue, I took the sealant and put it into the hole.

Now we take the coupling, remove the rubber ring from one side, lubricate it with glue or sealant and put it on again.

  Further, on our plug with a nipple, we also coat the edges with glue or sealant and insert it into the sleeve, that is, glue it.

From 110 pipes we measure 10 cm and cut it, cut the cut piece along the length.
We insert a cut piece of our pipe into the coupling, mark it along there to cut another piece, it should lie exactly in the coupling, look at the photo, it will be more clear there.
  Now we smear this piece with sealant or glue and insert the sleeve, and on top we glue another cut piece from 110 pipes, 5 centimeters and also glue it for strength, as in the picture.
Next, we take a suitable wooden block or plank, we can leave a square plank, but I decided to cut a circle with a jigsaw.
We put on a hose of a suitable diameter on the nipple and tighten it with a hose clamp.
In the plank I cut a groove under the nipple with a hose, smeared the plate with glue and glued our blank to it. Cut off the hose that comes from our billet
  and insert a triple into it (everything was bought in the same plumbing store).
We insert another small piece of hose into this tee, we insert a small faucet into it, to release air from our hydraulic jack.
And on the last, third end of the tee, we also put on a small piece of the hose and insert another nipple from the tubeless tube into it. But we prepare the nipple in advance, that is, we simply cut off its rubber, wide part,

  so that he easily sticks into the hose, then tighten with a hose clamp. We will supply air from the compressor to it.

Here's a look of a tee with all the connections ...

Next, on top of the coupling, we stick our gum,
which we lubricate in advance in lithol or something similar, we also need to lubricate our finished piston so that it slides better inside the coupling.
  We put the piston into the clutch.

But on top I decided to stick something else like a softener, but I did not find anything reasonable and stuck a circle cut out of plywood.

I also decided to immediately paint, there was only a yellow spray can with paint, so I shot it for beauty.
  The result is such a forked jack that easily raises the car ...
  and as before I lived without him;).

Now he is not an interchangeable assistant to raise the car, to change the wheel or something else.

But interesting tests with such a hydraulic jack;

To take up such "creativity" was prompted by a statement about the "hard" work of scribes of other people's homemade products. We will call this the "pen test."
In order to complicate the task for himself, he completed it with a video plot.

I must say right away, may the author forgive me and let him search for his creation on the Internet. I present YOUR own “creation” to your “court”.

Each motorist, with the purchase of a car, acquires a jack for servicing. Jacks are different, both purely mechanical and purely hydraulic. But they all have a major drawback, it is the convenience of use. It is impossible to install a jack under the car without bending into the "three-dooms". 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 combined the 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 an adaptation to it. The whole structure consists of a thick-walled channel for 80. made of a whole workpiece. Bends of the structure were achieved by cutting the side walls and further boiling. From the photo you can clearly see the device support rollers (wheels), to dwell on them I do not see the point. For direct support on the car body, a rubber support is fixed, it can be taken from the support pillows of the springs, the engine ... having finished to the desired size.

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

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

For rigidity, welders 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 up the device under the car, you, as usual, with the help of the handle, start lifting the main rod of the jack and thereby set the lifting lever in motion.

Due to the increased lifting lever, it is possible to completely raise the entire raised side. Both wheels are not supported.

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

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

What do you need to make such a "rolling" jack:
0. The head.
1. Ready hydraulic jack.
2. Channel thick-walled at 80, in the region of 1.5m.
3. Metal plates with a thickness of 5 to 10 mm, 150-200 cm square.
4. Metal "round" with a diameter of 12-16 mm. 1-1.5 meters.
5. The piston pin of the car.
6. Rubber "pillow".

The problem of lifting loads of large masses has faced humanity for a long time. In recent years, jacks have increasingly been used to solve it. Apart in this row is a hydraulic jack. He is capable of lifting really heavy loads with a minimum of effort. Hydraulics, since science appeared, came 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 you start work immediately, you must definitely 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 housing, 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 indicators acts as a working fluid. Conventional engine oil is not suitable in this situation.

It should be taken into account when developing the device. Typically, the housing 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.   The lifting mechanism and a special retractable hydraulic cylinder are capable of lifting the work platform. A sufficiently high pressure is created, which allows lifting loads of various masses. The housing of such a device can be both short and elongated. The second option is most often used when carrying out repairs of heavy equipment. For example, it can be a bus or a heavy truck.

Good day to all. I have a diamond jack, I lost the handle from it, it was made in the form of a hook. Raising a car with such a jack without a handle is not very convenient. In two or three stores I asked about the 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, it is already necessary to put the summer wheels, the 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.

So I sawed off the ear.

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

Now we take the welding machine and weld the head.

It turns out like this.

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

With such a head, it is easy to twist the jack and lift the car, it is especially convenient to twist the ratchet.

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

Well, that’s all, if this article helps someone, I’ll be very happy. The idea was spied on by Alexei from Tambov.

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 platform. Having such a jack in the trunk and hitting a marshy friable area, you can not be afraid to use it. In addition, with the help of it you can not only carry out the replacement of the problem wheel, but also get out of the mud. Working with him, special physical efforts are not required; therefore, it is even used in rigging.

The principle of operation of the pneumatic lift

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

To power such an instrument, it is placed under the bottom of the machine and connected to a pump or other air source, for example, a compressor or compressed gas cylinder. There are models that are particularly popular, as their work can be carried out, it is only necessary to connect such a jack to the exhaust gases of the car. For them there is no need to acquire additional equipment. Such designs are called air jacks or pneumodocrats.

For such a device, a hose is enough to connect the exhaust pipe and the jack itself, and then turn on the motor. Just 2 minutes is enough for the tool to do its job. In this embodiment 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 by which such a device is evaluated:

1. Carrying capacity. For the tool to be safe in operation, this figure 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 a car of the Gazelle type is 2.5-3 tons.
2. Pickup Height. You should pay special attention to this parameter if the machine has a low ground clearance. You should be interested in this point in the case of frequent stuck in the mud. It is best if this characteristic is within 10 cm.
3. Lifting height. In 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 that carries out rigging, and he, in turn, connects to compressors, then this characteristic will be more - up to 70 cm.

In any case, choosing a jack, you should focus on your personal car and the conditions in which it is most often located.

How to make a do-it-yourself jack

For you will need the following elements:

• old truck cushion;
• a bolt of the appropriate diameter;
• a ball that can be freely positioned in the bolt;
• wheel bolt from Lada;
• chamber fitting;
• drill.

From these components, the structure is assembled. A bolt is screwed into the hole of the pillow, 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 Lada, in which a hole should be made. Now these elements need to be connected. But before this is done, a ball is placed in the existing outlet, so that during operation it can close the hole, then air will not come out.

To use such a device, you 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 abut the car. If desired, a trolley with wheels can be attached to the lower part, then it will be a rolling jack.

There is one inconvenience of such a home-made device. The pillow from the truck is quite large. Therefore, if the car has a low landing, then it will constantly have to be lifted to expose the jack.

Lift Strength: Highlights

There are several options for how the jack can lift the car:

1. Pneumatics. In this embodiment, the load is lifted due to the force of compressed air. Such models work both from the equipment and from the exhaust gases of the car itself. Air enters the chamber, and that, in turn, begins to increase in volume, due to which the transport rises. Ease of use of such models is that special efforts are not applied, 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, in addition, they have small dimensions.
3. Hydraulic. The principle is similar to the previous version, the only difference is that in this case less effort will be spent. This is due to the fact that in the design of the device there is a liquid that ensures the ejection of the plunger with the load due to the pressure generated. 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 lights are turned off, you will have to work in the same way as an ordinary mechanical one, with the only difference being that more effort will be needed.

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

Despite the fact that the pneumatic jack is the easiest to operate, there are also its own nuances in its use. To avoid the tool escaping from under the machine, it must be correctly laid. Therefore, before using the new device, it is better to pump it once idle, after which it descends and folds properly itself. In the process, it will be useful to cover the surface of the floor and the jack with some rugs. This will protect the tool from damage.

Materials for the manufacture of the camera are taken on the basis of PVC, and it, in turn, becomes quite rough as soon as frost appears on the street. Optimal use until the thermometer shows -10, further operation becomes difficult.

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