A car jack is exactly the thing that every driver needs so much! In any car, whether it’s 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 with it, lifting loads has become 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 low load capacity. Although they are quite simple to use and easily fit in the trunk of a car, which can not be said about others. Hydraulic car jack is heavier and more powerful. A parallelogram jack is a complete analogue of this device. They are used in cases where the car has a rather large mass. In turn, these jacks are divided into rolling, lever and telescopic. The former have a lever that lifts the car, while the latter has a piston. There is also a vertical hydraulic car jack. Its advantage is that it can climb to a rather high height and has a huge carrying 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 machine itself, that is, 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 lift the car by half a meter and does not take up much space in the trunk.
For jeeps and minivans, rolling and link jacks are more suitable, which are most often used in car services and service stations. Due to their properties, they lift from 30 to 150 cm and above. However, transporting them is quite inconvenient due to their size.
A pneumatic car jack is less common among motorists due to the fact that it uses compressed air, which is rather difficult to keep in a confined space. He found his application with rescuers, with his help they penetrate places that cannot be opened manually.
The mechanical jack of a car is vertical and horizontal. The first option is quite inconvenient, since its pickup should be installed only in a certain place of the car, which after a while can simply be deformed. Horizontal or, as it is called, rhombic, more suitable option. It is small in size and easy to operate, although the drawback is its low payload. It is also necessary to remember that its installation must take place on a very flat surface, and the slightest bevel of the jack can lead to its breakdown.
Another lifting mechanism is rack and pinion. He found his application with truck drivers, and he simply could not fit into a small car.
Make the right choice.
