What is the most essential on-board tool since the invention of the automobile? Of course, a rolling jack! For an SUV, a car or a minibus, different designs will be needed, but one way or another it is impossible to do without it on a deserted highway if a tire is suddenly punctured and needs to be replaced. A trip even on a slightly flat tire to the service station can cost you a lot: breakdowns in the steering system and beaten suspension. Therefore, a jack must be in every trunk 24 hours a day, 7 days a week and 365 days a year. And it's not worth saving on this device. When choosing a rolling jack for an SUV, you should always look for the optimal device that would be a reliable assistant even in the most difficult situation. The road is a dangerous place, and you need to be fully armed.

Off-Road Jack: Types

The following types are distinguished:

Mechanical jacks. The simplest and, perhaps, the most reliable and compact devices. Available in the trunk of almost all small cars. They are distinguished by good mobility, but a relatively small carrying capacity. Depending on yourdesigns come in many types

Hydraulic jacks. The main purpose of this type is the lifting and / or movement of vehicles during repairs and maintenance. They are most actively used in auto repair shops and in production, but are becoming more and more popular in the life of motorists. The design of such a jack provides a smooth ride, reliable pickup and easy control, high load capacity and high efficiency (about 80%). It is important to remember that this device is designed exclusively for lifting, and not for long-term holding of the load. To avoid leakage of hydraulic fluid, always store and move it only in an upright position

Pneumatic jacks. They are used for work of various kinds and complexity. Such a rolling jack for an SUV is indispensable for moving and lifting loads, installation, repair work and much more. First of all, they are good because they can be used on absolutely any surface, whether it is loose soil or uneven ground

Now it is worth considering the subtypes of jacks in more detail. This will allow you to make the right choice when purchasing such an indispensable device.

Mechanical rack jack

Differs in a simple design: it consists of a vertical rack with teeth-hooks, along which the pickup (lifting rail) moves. The lifting process is carried out using a gear or lever transmission. To hold the load on the weight there is a latch-dog. This type of jacks is used not only for repair work in the car, but also for lifting loads in warehouses, construction sites, etc. That is why they come in various sizes and differ in different load capacities.

The main feature of such a device is the ability to lift loads that are low enough. But he also has his downsides. For example, due to the small area of support, such jacks cannot provide good stability to a car raised on one side, which requires the use of auxiliary devices to help fix the position. Also, to use such a jack, it is necessary to have special recesses in the bottom of the machine, which provide a place for installing the foot of the lifting rail or pickup tip. Some models are uncomfortable, bulky and heavy.

Mechanical screw jack

This mechanism works by converting the rotational movements of the screw rod into the translational movement of the lifting platform. The most common can be called a rhombic screw jack, which consists of 4 arms interconnected by hinges in such a way that as a result a rhombus is obtained from them. The stem is a horizontal diagonal, with twisting of which the opposite corners turn around and approach each other. At the same time, they move away from each other along a vertical diagonal, at the ends of which there are a lifting foot and a support heel.

Automotive hydraulicjack

In order to create a working pressure of the liquid, an electric compressor or a pump handle (manual method) is used in this design. Such mechanisms have the following advantages:

- good stability, - compact design, - fast ascent without any physical difficulty.

They also come in different types, each with its own specific features.

Hydraulic bottle jack

The bearing elements of this design are the housing and the retractable piston, and the working fluid is filled with a special liquid. The housing is both a piston guide cylinder and a fluid reservoir.

When choosing such a jack, you need to take into account not only its carrying capacity, but also the pickup / lifting height, because even if it can withstand the weight of your car, it may simply not have enough working stroke to raise it to the desired height.

Trolling hydraulic jack

This design has undeniable advantages among all similar mechanisms. Firstly, the rolling jack (the instruction contains this information) has a higher load capacity than its counterparts, while it is much smaller in size. Also, high efficiency and a higher power transfer coefficient make this jack more advantageous in comparison with others. Attention deserves the smooth movement of the main lifting mechanism. Rolling hydraulic deviceThe jack, unfortunately, cannot boast of a large lifting height and needs almost constant service. The service life of such structures, as a rule, is much less, and in the event of a breakdown, repairs will cost a round sum. Although, for example, a rolling jack with a latch is much more convenient and reliable in the process of car repair than an ordinary diamond one. Thanks to the latch dog, this mechanism becomes more stable and allows you to apply less effort. The rolling jack, the instruction to which is always attached, is the most popular among all others, especially among owners of large cars and minibuses.

Pneumatic car jack

This device looks like an inflatable pillow filled with compressed air. It can also be filled with exhaust gases. The hydraulic mechanism in this case is highly stable, as it has the largest support area. The pneumatic rolling jack needs a pressurized air supply to inflate the main structure. For this, special cylinders or gases from the exhaust pipe of the machine are used, which ensures minimal effort and time. At the same time, the lifting speed of any load is quite high.

These jacks are most commonly used in service stations or garages, but more recently they have been used more and more to recover cars that are stuck in swamps or mud, making them more popular among drivers of oversized vehicles.

The indisputable advantages of such mechanisms can be considered the possibility of using on absolutely any surface. Whether it's soil, earth, uneven roadway - such a jack can handle everything. It is easy to use, has a large lift height, does not require much effort, but boasts an impressive load capacity. Also, such a jack can be placed under any car, regardless of the design, damage and other features.

At the same time, he has his own minor disadvantages. For example, when pumping with exhaust gases, a corrosive residue gradually accumulates in the chamber, and during installation, you first need to inspect the surface to make sure that there are no piercing objects, glass fragments, sharp metal parts that can accidentally pierce the chamber. And of course, when using compressed air, you will need a separate compressor, which also costs money.
