WHAT DO I NEED TO KNOW ABOUT CAR JACKS?
It is very annoying when this or that trouble occurs on the way, which forces the motorist to radically change the plans. The car is undoubtedly a complicated mechanism, but nobody is insured from breakages, even the owners of the most modern and expensive “iron horses”. However, it is even more unpleasant, when this very problem does not depend on car owner or car’s condition. We are talking about tire damage, because the quality of roads leaves much to be desired. But it doesn’t hurt when you have to resort to the service toronto car scrap.
It is quite clear that this problem is not the most serious, but it is still necessary to spend some time for wheel replacement. Therefore it is obligatory to have spare tire at all times. But there is one more means, without which this procedure becomes impossible – car jack. Because for full replacement of a wheel the car should be lifted, and it is usually unrealistic to do without a special tool.
Currently there are several varieties of jacks, which have both disadvantages and advantages.
Hydraulic jacks – operate on the principle of interacting vessels, and the role of the working fluid is given to a special hydraulic oil. With the use of the suction and discharge valves inside the cylinder, the necessary pressure values are created. As a rule, the following types of devices are used for automobiles:
Bottle jacks – are able to lift a vehicle with a weight of up to a hundred tons, so this type of jacks is often used for trucks.
Rolling-up – they work by means of a lifting lever, and the principle of operation is similar to the bottle jack. Such devices can often be found at tire repair shops.
Pneumatic-type jacks, compared to the hydraulic ones, work using air. Due to the fact that they have a fairly large lifting area, it is much easier to reach with pneumatic jacks in hard-to-reach areas where the distance between the support and the load is very small. Often pneumatic type equipment is used in emergency and rescue work.
Screwed rhombus jacks are the most popular. These devices are a clamp that compresses a pair of shoulders. However, this tool does not have a large lifting capacity (not more than one and a half tons). Therefore, these jacks are used exclusively for cars.
Rack-type car jacks are characterized by a large lifting capacity and can be used on trucks.
The choice of a suitable car jack depends on quite a number of factors, but the most important criteria are the purpose and the frequency of use. So, motorists often buy car jacks to carry it in the car and use it in emergency situations. In this situation, it is recommended to look at your luggage compartment – will the tool fit there.
For the systematic repair of the vehicle in the garage, a bottle-type jack is perfect. Because it can easily handle absolutely all necessary tasks.
It is also necessary to choose a good manufacturer, so that the equipment was as reliable as possible. In order not to make the procedure of auto-wheel replacement a real agony, besides the jack there should be a ballon key, a handle and a folding stop for the wheel in the set. It will not be superfluous and the liquid which will help in unscrewing the connections, prone to corrosion. It is necessary to pay attention to the cost of the car jack – it is recommended to pay more, but to have a high-quality tool.
