Today in our article we will consider a variety of jack models. The jack must be in every trunk, because only with it you can raise the car and replace the wheel. Car jacks in the Russian market are quite widely represented. There are models made in China, Europe, Taiwan and the USA. The cheapest and most often breaking are jacks from China. From Europe and the USA too expensive. Now all the products from Taiwan have become more popular, which have a reliable price and an acceptable price. Not surprising, since Taiwan is a modern forge of tools with modern factories and qualified labor.
Varieties of the jacks of the type of rise in the rise:
1) hydraulic;
2) pneumohydraulic;
3) mechanical;
4) pneumatic;
5) air (from exhaust gases).
Hydraulic
Use hydraulic fluid in the design of equipment, which significantly increases the effect on the jack handle. The disadvantage of such jacks is the fact that they cannot hold the entire car for a long time, since gradually the liquid goes through the gaskets, lowering the weight below. Therefore, after lifting the cargo to hold it at this height, it is recommended to use safety stands for the car.
Pneumatic
In appearance, they resemble a pillow that is made of strong rubber. Such jacks are placed under the car and inflated using compressed air, which is supplied from the compressor. In the process of inflating, the jack meets the resistance of the weight and lifts the load. If hydraulic jacks do not require the purchase of additional equipment, then this category of jacks requires equipping a special pneumatic massagistan. You need to buy a compressor, air preparation unit, a hose and fittings that will connect all elements to the system. Therefore, this type of jack will require additional and not the smallest investment of cash.
Pneumohydraulic
Combine both types of previous jacks and have an increased carrying capacity.
Mechanical
The type of jacks that work only at the expense of human strength. The main element of such jacks is a screw and lever. When spinning the screw using the lever, the machine rises, and with reverse rotation is lowered. I must say that when using such jacks, only human strength is needed. Working with them, the time to raise part of the car increases and a person has fatigue.
Air (from the exhaust pipe)
Recently, a very popular type of jack. He, like a pneumatic, looks like a pillow that is inflated due to the gas of the exhaust pipe. One hose is connected to the exhaust pipe, and on the other hand to the jack.
In this article, we tried to consider the main types of jacks, which are now widely used both by ordinary motorists and car services and tires.
