A car jack is exactly the thing that every driver needs so much! In any car, whether it be a foreign car or our domestic "passenger car", there must be such a lifting assistant. The lever is a very useful invention of mankind, because it has made lifting loads much easier.
Currently, there are mechanical, hydraulic and pneumatic jacks. The first are divided into folding and lever, which have practically lost their relevance. This is due to the fact that they have a small carrying capacity. Although they are quite easy to use and easily fit in the trunk of a car, which cannot be said about others. The hydraulic car jack is heavier and more powerful. The parallelogram jack is a complete analogue of this device. They are used in cases where the car has a fairly large mass. In turn, these jacks are divided into rolling, lever and telescopic. The first has a lever that raises the car, the second has a piston. There is also a vertical hydraulic car jack. Its advantage is that it can climbrather large height and has a huge load capacity, so it is more applicable to trucks. However, there is a minus - it must be constantly kept in a vertical position, which is very difficult during transportation.
When choosing a car jack, it is worth considering the data of the car itself, that is, the weight and dimensions. If it weighs about a ton, then a simple folding jack is enough. For the middle class, a hydraulic jack is suitable, which can raise the car by half a meter and does not take up much space in the trunk.
For jeeps and minivans, rolling and lever jacks are more suitable, which are most often used in car services and service stations. Due to their properties, they produce a rise from 30 to 150 cm and above. However, they are quite inconvenient to transport due to their size.
Pneumatic car jack is less common among motorists due to the fact that it uses compressed air, which is quite difficult to keep in a confined space. It has found its use among rescuers, with its help they penetrate into places that cannot be opened manually.
Mechanical car jack is vertical and horizontal. The first option is rather inconvenient, since its pickup should only be installed in a certain place on the car, which after a while can simply be deformed. Horizontal or, as it is called, rhombus, a more suitable option. It is small in size and easy to operate, although the disadvantage is the smallload capacity. It is also necessary to remember that its installation should take place on a very flat surface, and the slightest bevel of the jack can lead to its breakage.
Another lifting mechanism is rack and pinion. It has found its use in truck drivers, but it simply will not fit into a small car.
Make the right choice.
