Not rare car owners asking advice, what car jack is better to choose. It is enough to visit any forum dedicated to this topic to make sure how many people, so many opinions. Moreover, everyone, as a rule, stands on its own, motivating this by the fact that it uses the device that recommends. As a result, the person who asked the Council is finally confused. In order to avoid such an outcome, it is desirable to sort out all the nuances. After all, probably, no one better than the owner of the car does not know about its terms and features of operation. In practice, the algorithm for choosing a car jack is quite simple. About this further in the article.

Autodomkrat, why he should always be present in the car trunk

It is no secret that in the far drove road can expect such a trouble as the tire descent. The tire can simply burst, and not a single "tire unit" will not be nearby. Of course, you can always call the tow truck, but it does not rarely happen such that the phone refuses to call, because "does not catch" the network, especially if you are far from the city. In this case, you will suggest a long time on the road, until someone go past. That is why a jack must be present in the trunk of every motorist, since if it is presented, you will fix this breakdown for fifteen minutes.

Safety when working with an autodcomkrat

Car jack is used exclusively for lifting the vehicle. To hold the car on the raised height, only one jack is not enough. Do not risk your life and your health, do not climb the vehicle that keeps only on the jack. Remember, if you need to climb under the car, it is mandatory to use special supports.

Autodomkrat, main characteristics of the jack

1. Load capacity. Each car jack is calculated on the rise of the specific mass of cargo, and also has the most allowable values \u200b\u200bby weight, which cannot be exceeded. Violation of this rule may cause a car damage or breakdowns of the lifting mechanism itself. The device can simply not withstand a large load. That is why when purchasing it is necessary to take into account the weight of the car that you have to raise. However, this should take the intended actual mass, and not equipped, taking into account the transported cargo in the body or the trunk of the car (spare, fire extinguisher and so on).
   
2. Maximum lifting height. This characteristic indicates which height from the point of the support, that is, from the ground, the jack can raise the cargo. This parameter in most models is 300-500 millimeters. This height is enough to remove the vehicle wheel or gain access to the parking brake cable. Rush jacks are able to raise transport to height more than one meter from the ground, however, the use of such mechanisms will be rational only in a narrow sphere, for example, when moving off-road, when it is necessary to lift the SUV, bonding in the mud or in construction to lift heavy structures.
   
3. Height of pickup. This parameter indicates the distance from the Earth (lifting point) to the bottom of the vehicle from which the rise is made. At various jacks, the height of the pickup varies from 60 to 250 millimeters. You need to choose, based on what your car is clearance, that is, the ground clearance.
   
4. Type of drive. By type of drive, there are three types of jacks - mechanical, hydraulic and pneumatic.

Jack screw rhombic, principle of operation, dignity and disadvantages

Screw rhombic jacks are the most common among modern screw mechanisms. Their principle of operation consists in changing the angles between 4 hinged fixed rigid ribs using clamps. Thanks to this, the load is raised and its lowering. Among their merits, it is worth highlighting low cost, simplicity and compactness, and among the minuses - a large effort at first lifting and in some cases there is an insufficient minimum pickup.

Autodomkrat War, principle of work, dignity and disadvantages

Rachet jacks have completed old models of transport, for example, GAZ 21 "Volga". The main carrying element of their design is a toothed unilateral rail, according to which the housing of the ratchet mechanism is moved, on which the folding pickup is fixed. You can change the direction of movement using the up-down switch. Their carrying capacity ranged from 0.5 tons.

As for modern models, their carrying capacity is 2-2.5 tons and more. They are able to raise the vehicle to a height of one meter (and this is not the limit). In addition, with the help of special loops, they can be used as a manual winch. Their benefits are the maximum rise height and a large working stroke, constant effort during the entire working stroke. The disadvantages include an impressive mass and dimensions, especially concerns modern models.

Hydraulic jack, principle of operation, dignity and disadvantages

Hydraulic jacks are considered to be "heavy artillery", since their carrying capacity is from one to several hundred tons than their use when repairing freight transport and other heavy machinery. In its design, they are single and multi-vent.

The main carrier elements are: body, working fluid (usually oil) and piston extended (plunger). The housing performs the following functions: For piston, the housing is a guide cylinder, and for the working fluid - the tank. The plunger screws up a screw with a special lifting fifth. So, if necessary, you can increase the maximum height of the lift, turning the screw.

From the drive handle, the force is transmitted by lever to the discharge pump. During the movement, it takes absorption of the liquid from the tank to the pump cavity, and during the press - the discharge into the cavity of the cylinder. The injection and suction valve prevent the reverse flow of fluid. To lower the cargo, you need to unscrew the locking needle. The fluid is displaced from the pump cavity back to the tank.

With all their power, hydraulic jacks are among the most whimsical. For example, to support the jack in working condition, you need to follow the tightness of the valves and the glands, as well as systematically monitor the oil level. It is possible to store and transport such a jack only in a vertical position, otherwise, the oil (working fluid) can be found out of the tank.

Advantages - good stability, stiffness of construction, a slight force on the drive handle. Disadvantages - small working stroke (only for a single-glazer), a complex device, high cost, a large mass, as well as the initial height of the lift.

Pneumatic jack, principle of work, dignity and disadvantages

Such a lift is indispensable when you need to raise the cargo on a swampy, loose or uneven surface. The principle of operation of a pneumatic jack is based on the use of compressed air supplied using a compressor or a pump. The jack can work from the generator or the power grid. The cargo rises by air, which enters the pillow. Since strongly compressed air is difficult to hold in the cylinder, pneumatic jacks are not often used by ordinary car owners.

Externally, the pneumatic lift is an elastic pneumatic plow, and a piston / pump located in the cylinder. As a result of the fact that in the original form, the pillow is flat, there is an opportunity to put it download even if the distance between the surface is minimal. They also have a fairly large grip area. Pneumatic jacks are two- and three-decree. They are characterized by a good indicator of carrying capacity and maximum height.

Jack is passenger, which jack is suitable for a passenger car

For a passenger car, a rhombic screw jack is suitable, the possibilities of which are universal, and the cost is quite small. It makes no sense to take too massive lifts of this type, quite a stock of 500-600 kilograms from the mass of the equipped vehicle. The most optimal option is a jack, which is able to raise the cargo in two tons, because the mass of a modern car rarely exceeds 1.5 tons.
