What kind of jack should I buy?

Roadside assistance today offers many services, including buying you gas, charging your battery, and taking you to the nearest service center. On the other hand, if you find yourself in the middle of a highway and need to change only your tire, there is no need to wait for hours helplessly staring and anxiously waiting. If you always carry a jack in your trunk, you will save time and money, as well as avoid numerous other inconveniences.

The main function of a jack is to lift the vehicle off the ground at a specific point. There are mechanical and hydraulic jacks available. Most mechanical models use a screw or lever that needs to be turned to operate. Hydraulic models work with a pressurized hydraulic cylinder, strong enough to lift heavy loads. To keep the car stable, jacks are used in combination with stands. Even then, under no circumstances should you lie under a car lifted solely by a jack. It’s possible that you have stopped on an incline without realizing it.

Jacks also differ in type and purpose. The most popular are scissor jacks, also known as car jacks, bottle jacks, screw jacks, or lantern jacks. They are easy to transport and store, safe to use, do not take up much space, and can lift up to 1.5 tons of weight using just a manual crank. Depending on the type, they can raise the chassis to a height of 30-75 cm.

A crocodile jack is used for agricultural equipment, trucks, and jeeps, so they are also called jeep jacks. These models are also easy to store and can help you both change a tire and get out of deep mud or difficult terrain. An excellent option for all vehicles with high suspension.

The hydraulic jack, also known as an oil jack, was invented by Richard Dudgeon and operates based on Pascal’s law – a small force is applied over a smaller area, generating pressure in the fluid. Then the force is applied over a wider area, providing enough power for lifting. The hydraulic jack is suitable for heavy loads, easy to use, and offers high efficiency. It looks like a bottle and is mainly suitable for home repairs, not on the road.

A giraffe jack is used for high lifting, mainly on off-road paths. Additionally, it is powerful – it can withstand loads up to 3200 kg and lifts the chassis to a height of up to 2.5 m. Useful for off-road jeeps and agricultural machinery.

A lizard jack, also known as a floor jack, is hydraulic but uses a manual lever for lifting. These models are extremely sturdy and do not require knowledge to use them. Floor jacks are chosen according to the weight of the vehicle, which means that not every model is suitable for the road. However, they have wheels and a stable base.

Popular is also the pneumatic jack, which has the shape of a balloon and is suitable for lifting buses, trucks, and construction vehicles. A variant for cars is the air cushion jack, which is used on off-road terrain where the surface is uneven, as well as places covered with snow, mud, or sand. Regardless of which jack you choose, find a suitable place to park, secure the vehicle, locate the correct points for placing the jack, and always use a stand.
