For every motorist, whether an experienced mechanic or an ordinary driver, a car jack is not just a tool, but a necessary element of safety and reliability. It is impossible to imagine a complete tire repair on the road, replacement of seasonal tires in the garage or more serious work without the ability to quickly and safely lift the car. In today's world, where the tool market is overflowing with variety, choosing the right jack can be a real challenge. Which car jack is best for you? This article will help you understand the types of jacks and their features so that you can make an informed choice.
Why do you need a car jack?
First of all, a car jack is designed to quickly raise a part of a vehicle to a certain height. This allows you to carry out the necessary manipulations: replace a punctured wheel, inspect the undercarriage, perform minor repairs under the car. The presence of a reliable jack in the trunk gives confidence in any trip, especially when it comes to long routes or trips outside the boundaries of paved roads.
Key parameters for choosing a jack: load capacity and lifting height
Regardless of the type, the main characteristic of any jack is its load capacity. It determines the maximum weight that the tool can lift without risk of breakage or deformation. When choosing a jack for a car, always focus on the total weight of your car (indicated in the technical data sheet) and add a reserve of at least 20-30%. This is important, because the car may be loaded, or you will be lifting it on an uneven surface, which increases the load on the jack.
Incorrectly selected load capacity can lead to:
- Damage to the jack itself at the very first use.
- Failure of the jack during operation, which is extremely dangerous and can cause serious injury or damage to the vehicle.
In addition to the load capacity, the lifting height and pick-up height are important. Pick-up height shows the minimum height from which the jack can start lifting (important for cars with low ground clearance), and the lift height shows the maximum height at which it can lift a load.
The main types of car jacks: advantages and disadvantages
The modern market offers a wide range of types of jacks, each of which has its own design features, advantages and disadvantages. Let's consider the most popular of them.
Mechanical jacks (rhombic,bottled)
The principle of operation: lifting is carried out due to the mechanical transmission of force through a screw pair.
Rhombic jack — the most common type, which is often included with passenger cars.
- Pros: compactness, lightness, low price, ease of use. Ideal if you need to buy a car jack for road emergencies.
- Cons: low load capacity (usually up to 1.5-2 tons), requires significant physical effort, instability on uneven surfaces, relatively low lifting speed. Not suitable for intensive use or heavy cars.
Bottle (or telescopic) mechanical jack— Very compact, works due to the rotation of the screw. It has a cylindrical shape, similar to a bottle.
- Pros: compactness, sufficient stability, simplicity.
- Cons: slow rise, requires physical effort, due to its shape, it does not have the best pick-up height, so it is not suitable for cars with low ground clearance.
Hydraulic jacks (bottle,rolling)
The principle of operation: lifting is carried out due to the compression of liquid (oil) in the cylinder, which creates high pressure.
Bottledhydraulic jack— outwardly very similar to its mechanical counterpart, but a small lever is used for lifting, instead of a screw.
- Pros: high load capacity (models from 2 to 20 and even 50 tons can be found), minimal physical effort for lifting, high stability due to a wide base. An excellent choice for trucks or heavy SUVs. If equipped with an emergency valve, it will not allow to exceed the design weight limit. If you want to buy a jack for a passenger car, but with a margin of strength and for frequent use, this is a good option.
- Cons: not suitable for very low cars, sensitive to horizontal position (lubricant may leak when stored horizontally), requires maintenance, primarily checking the fluid level.
Rolling jack— equipped with wheels and a long handle, which allows you to easily roll it under the car.
- Pros: convenience and speed of use (especially on a flat, hard surface of a service station or garage), low lift, high load capacity (usually from 2 to 10 tons), ease of maneuvering. Ideal for garages, tire fitters and private workshops that often work with a variety of vehicles.
- Cons: large dimensions and weight, not suitable for use on uneven ground or in field conditions, requires a flat and solid surface for stable operation.
Pneumatic jacks(roll-up, pillow)
They can be rollable or in the form of a separate air cushion.
The principle of operation: lifting is carried out by filling a special rubber container with air (from the compressor or the exhaust pipe of the car).
- Pros: very fast ascent, minimal effort, in the case of a separate pillow, it can work on soft and uneven surfaces (sand, mud, snow), high load capacity (from 2 to 40 tons). In the roll-up version, it is an excellent choice for tire fitting and service stations where an instant lift is required. And a separate pillow is indispensable on off-road.
- Cons: requires a source of compressed air, sensitivity of the rubber container to sharp objects, relatively high price.
Rail jacks(Hi-Lift Jack)
Principle of operation: Lifting is carried out using a lever mechanism on a rail with holes.
- Pros: high load capacity, ability to lift the car to a great height, versatility of lifting points (bumper, power threshold, wheel), indispensable for off-road and car evacuation from swamps, ruts, ditches. Ideal for owners of pickups, jeeps, all-terrain vehicles, so it is popularly considered an "off-road" jack.
- Disadvantages: large dimensions and weight, requires considerable physical effort to lift, less stability compared to hydraulic on hard surfaces, potentially dangerous if used incorrectly (skills and caution required).
How to make the right choice: tips from Vnedorognik.ua
Choosing the best car jack depends on your individual needs, vehicle type and usage conditions.
For cars and "garage" work: If you need to buy a car jack for occasional wheel changes or simple repairs, a diamond or small bottle hydraulic jack is a great choice. They are compact, affordable and quite reliable for such tasks.
For the workshop, service station, tire shop: If you are a professional repairman or have your own workshop, a retractable hydraulic or retractable pneumatic jack will be an indispensable assistant. Its convenience and speed will pay for themselves.
For trucks and heavy equipment: Definitely choose a powerful, high-capacity, bottle-type hydraulic jack.
For off-road vehicles and extreme conditions: If you are the owner of an off-road vehicle and often go off-road, be sure to pay attention to the rail jack. It is your reliable assistant in difficult situations when ordinary jacks are powerless. An off-road jack should be as reliable and versatile as possible.
