Car jack

Car jacks are used when replacing wheels, exhaust silencers, repairing the chassis. With these compact devices, one can lift a vehicle to the optimal height for performing certain operations.

What are the types of car jacks

Devices offered in catalogues of car accessories are divided into:

• Mechanical. They have the simplest design and are sold inexpensively. They are widely used by passenger car owners for DIY part replacement. At a service station they are mostly used for urgent or off-site repair.
• Pneumatic. Their operation depends on the supply of air or gas under high pressure. Such devices lift the car rather quickly and thus they don’t require significant effort from a person.
• Hydraulic. They feature a fast operation together with a rather affordable price. They are quite compact but, at the same time, they have good lifting capacity as well as performance coefficient. The working pressure is created manually or with an electric compressor.

According to design car jacks can be:

• bottle;
• trolley;
• scissor;
• high-lift.

When choosing the device in an online shop take into account that devices differ also in the following characteristics:

• Lifting capacity. It defines the maximum weight of a car you will be able to lift. This parameter can be from 1.5 to 50 tonnes.  It is recommended to buy a device with a higher lifting capacity than it is required for your car. Otherwise, it may get out of order soon.
• Maximum lifting height. For example, there are models with this parameter equalling 340, 480, 520 mm.
• Minimum height. It is a minimum level where one can start lifting a vehicle. This value can be 140, 210, 300 mm, for example. Take into account that the accessory should fit under the car easily.
