If you own a car, you just have to have an automobile floor jack in your maintenance toolkit. When you buy a car you will get a specific
automotive jack with it, but you may need to replace it in the future if you break or lose it. If you buy a used car you may not get it at all. Be careful, when choosing a replacement for your former car jack because different jacks serve different cars.
The main purpose of a car jack is lifting any part of a car. It is often used when one needs to change a tire, but that is not the only way of using an automotive floor jack. As usual a car jack can lift only a part of a car (a corner, for example), but there are some specialized jacks which are able to raise the entire back or front of the car if needed.
Automotive companies prefer to provide scissor jacks with their cars. This type of jacks utilizes the central screw mechanism for raising and lowering a car. This mechanism is brought to action by a special handle (supplied with a jack) or by a simple tire removal tool.
For lifting trucks and other large vehicles you have to use specialized jacks, fitted with a large flat base plate, ratcheting mechanism and a long shaft with large teeth.
Hydraulic automotive jacks are very popular as well. There are both wheeled and non-wheeled versions of hydraulic jacks.
The last type of car jacks which is often used in car repair shops is a large
floor jack, which operates with the help of hydraulic fluid. One can lift the whole back of a car with such a jack.
There are some safety features in every automotive jack which will prevent you from being injured. A wide base prevents the jack from sinking into the soil or tilting. Most jacks are fitted with a special mechanism or a handle for lifting a vehicle. However, there are automotive jacks which can be operated with the help of a simple tire repair tool. A stop point on a jack helps to avoid overextending it beyond its capabilities.
Having a car jack at hand when on the road has a lot of benefits. Its major benefit is the ability to quickly change tires in the situation, when you cannot call for help, or you consider calling too expensive for you. Surely, you can use the tool for any other task (like changing brake pads, belts, oil) if you like to do all the maintenance by your own. If used in accordance to its manual, an automotive car jack is a very helpful tool for every car owner.
