Car jack for your car

Car jacks are devices which are used for lifting cars and holding them for some time on the set height. These devices can be needed for performing diagnostics and repair of suspension and running gear. Particularly, replacing wheels by yourself, you won’t do without jack.

Types of car jacks

First of all the devices differ by operating principle. They are:

• Hydraulic. They work due to pressure of working liquid (hydraulic oil), which shifts the piston. Pressure is created by the jack pump and provides large lifting capacity at insignificant physical efforts.
• Pneumatic. They include a pressurized robust hollow chamber, for example, a balloon, which lifts a load by expanding when the compressor inflates it with air or, for example, with exhaust gases.
• Mechanical. These products create the necessary effort due to lever, screw or toothed mechanisms. They are of small lifting capacity.

Depending on the drive type car jacks can be:

• Electrical. They are powered from the cigar socket or directly from the battery.
• Manual. They function due to man’s efforts, as a rule, through operating the handle.

Also, car jacks are different by the design. Devices of the following types are the most common:

• Bottle jacks. They are simple hydraulic mechanisms with high lifting capacity. This type of jacks is characterized by great stability and is used not only for passenger cars maintenance, but for large vehicles as well.
• Trolley jacks. They are handy devices with the long handle. These products are equipped with wheels which allow to easily move the tool under the car.
• Screw jacks. They are stable, durable and reliable products which set a load on needed height with the help of a thread. The most popular jacks are scissor screw jacks.
• Rack jacks. They are easy-to-operate products with smooth travel and lifting capacity of 0.5 ton and above. This parameter directly depends on quantity of gears in the mechanism.

Also, the manufacturers offer telescopic jacks and other products. Some devices have large dimensions, that is why they are used mostly at car service stations. Trolley jacks, for example, can be among them.

Tips on car jacks use

Follow manufacturers instructions and safety rules for safe and effective work with the jack. Particularly, when working with the car jack, you need to place additional jack stands under the car load-carrying elements. If the device requires more efforts at lifting than earlier, has cracks or other damages, it is recommended to stop using it and address to the service centre for diagnostics performing. Moreover, it is recommended to perform annual check in special repair shops.

The tool should be stored in the clean dry place out of children’s reach. You need to regularly check the device for corrosion marks. In order to avoid rust formation, you should apply special grease to working elements of the mechanism.
