It called jack Car tool, which is used to lift the car to a certain height. Cases in which the jack is needed, there are quite often, so it should always be kept at hand. In our time to choose a suitable jack for your car it is very difficult. It earlier when choosing car owners did not experience any difficulties, since there were only three variations. Today, the car market is packed with different models of foreign and domestic companies. Each manufacturer is their models with unique features, advantages and features of the design. About this further in the article.

Kinds of car jacks

There are several basic types of car jacks:

1. Compact, mechanical. These include rack and screw jacks.
   
2. Hydraulic jacks or stable.
3. Pneumatic - professional jacks, used in car repair. These include podkatnye and hydraulic variations. These devices are quite stable and have a high load-carrying capacity.
   

jacks automobile Hydraulic

Hydraulic lifting mechanisms have the following advantages:

1. Compact and convenient design.
2. Quick and easy recovery.
3. Good load resistance.

In the hydraulic jack, the working fluid pressure can be created using an electrical compressor or manually by means of the pump handle. According to constructive execution, there are rigged jacks and vertical bakery lifting mechanisms. The first were installed on the wheels, and due to their rapid work and mobility, we found wide use in the car service and a hundred. They are effective in the case when their use occurs quite intensively.

Unconditional advantages of the hydraulic jack:

1. The optimal rate of effort.
2. Smooth movement of the lifting device.
3. The great value of the efficiency.
4. High lifting performance.
5. Small size of the jack.

Disadvantages of hydraulic lifts:

1. Small lifting height.
2. Little service life.
3. Expensive recovery.
4. Continuous maintenance is necessary.

screw jack

In the screw jacks, the load lift occurs due to the rotation of the drive handle. Rhombic screw jacks are widespread, which consist of four shoulders forming a movable rhombus. From above there is a platform that holds the vehicle. These jacks are characterized by good stability and high reliability. In comparison with the rush jack, the screw lifting mechanism has a small lifting height, which is slightly for the work on changing the wheel. In addition, in the folded state, the device takes up little space, as a result of which is very popular among car owners. It will not be possible to apply it for very heavy cars.

pneumatic jack

The pneumatic jack is an inflatable pillow, which is pumped up with exhaust gases or compressed air. It is highly resistant thanks to a large support area. To raise the cargo, the pneumatic jack requires supplying gases or air under rather high pressure, for which car exhaust pipes or gas cylinders are used.

By air pressure, the camera inflates and raises the vehicle. Here the driver actually does not make efforts to lift the car. In comparison with other variations of jacks, the pneumatic lifting mechanism provides the least labor costs for lifting cargo. The speed of the car lifting is also high enough.

This jack has found application in construction, a service station, and is also often used to evacuate the vehicle stuck in the swamp and dirt. Advantages of pneumatic jacks:

1. Easy installation of the jack.
2. Quite high rise.
3. Good lifting performance.
4. Minimum effort from the driver.
5. Advancement to any state of the roadway.

Disadvantages of pneumatic lifting mechanisms:

1. The need for a separate compressor when applying compressed air.
2. When installing the chamber, it is necessary to eliminate the presence of cutting and acute items that are able to damage it.
3. In the process of pumping out the exhaust gases inside the chamber accumulates a caustic precipitate.

electric jacks

Despite the need for electricity, these devices are capable of working autonomously. In other words, they are not necessarily connected to the outlet. Often for power supply, the device is connected to the onboard electrical network of the car. And it doesn't matter whether the motor is currently working or not. The mechanism of operation of the electric lifting device:

1. The device connects to the network (as a rule, through the cigarette lighter).
2. The connection signal is supplied by wires to the jack microcircuit.
3. The signal is sent to the instrument motor.
4. With the help of the control panel, the car owner sets the desired height to which the car must be raised.
5. The chip and the jack engine receive this information and proceed to perform the operation.

It is worth saying that the price of electrical products is much higher than, for example, hydraulic or mechanical jacks, so choose the device is especially careful.

dombra Rombic

In the modern market there are two types of rhombic jacks - screw mechanical and hydraulic. Load capacity varies within 0.7 - 2 tons. The advantages of rhombic jacks:

1. Universality.
2. Large support surface.
3. Stiffness design.

Cons of a rhombic lifting mechanism:

For mechanical - increased effort on the handle, a small workforce.

For hydraulic - a large mass and high cost.

bottle jack

The bottle jack is used in different areas of the economy, is characterized by convenient operation, ease of device. It is used to lift special equipment, cargo and passenger vehicles. During construction, it is possible to raise the building with it. The main condition - it is necessary that the weight of the cargo corresponds to the mechanism specified in the manual.

Best jack, how to choose

When choosing a car jack, you must pay special attention to its main technical characteristics:

1. Stability. It is necessary to take into account the ability of the device to keep the working position in difficult conditions, for example, when the wind is entering.
2. Working is the distance between the upper and lower working position of pickup.
3. Load capacity. The maximum effort that reaches the device. Often there are mechanisms with a carrying capacity of up to two tons - this is the optimal indicator.
4. Picking The lifting heel or platform for stopping the car is in the form of a rigid fixed bracket or a folding rod. Here it is necessary to take into account the clearance of the vehicle.
   
5. Support site. Here it is necessary to take into account lateral sliding and minimal entry into the ground.
6. Lifting height. The optimal height is half a meter.
7. Drive handle force. What an effort must be attached to lifting the cargo.
8. The type of actuator is mechanical (suitable for rare use), hydraulic and pneumatic (if work must be carried out continually).

In addition to the above characteristics of the product, the quality of the jack production has an important value when it is elected.

If it is manufactured inactively and poorly, its declared characteristics may well and do not correspond to reality.

When you buy a jack, check it out and pay attention to its appearance, reliability of attachment of nodes, stability in the deployed and rolled position, the absence of free stroke and backlash.

Pneumatic and hydraulic jacks must be checked for the presence of gas and liquid leaks. Mechanical products Check for the absence of hotels and smoothness. No need to forget that the basic requirements for the mechanism are safety and reliability.

Not recent criteria - weight and dimensions of the jack. He must take a little space and place in the car trunk.

Rule Rules Auto Jack, Step-by-step instructions

1. A car lift on the jack only produce on the horizontal surface to eliminate the appearance in the raised position of the side of the rolling force.
2. Before starting the rise, block the two opposing TC wheels using pads, logs or bricks, which would not move back or forward.
3. Do not lift the car on the jack if the PPC is enabled. Before lifting, put KP in a neutral position.
4. If you need to raise both rear wheels, lock the front wheels on both sides.
5. If you need to raise both front wheels, put cars to the parking brake and block the rear wheels on both sides.
6. Produce a smooth lift of the car, avoiding rolling and jerks.
7. After the end of the lifting of the car, check it out by swaying on various sides, in order to avoid its fall from the gust of the wind or push.
