Jack Is a device that allows you to lift the maximum permissible weight to a certain height. Such devices can be several types... Let's review several similar products.

This is the most common type of rolling jacks, which is more common than others. It works by pumping oil from the expansion tank to the slave cylinder using a hand pump. Oil trapped in the cylinder begins to squeeze it out. The extension length depends on the amount of oil supplied. Thanks to the safety valve, with overpressure in the cylinder, the oil will not squeeze out the sealing lips, but will go back to the expansion tank.

Jacks of this type are very popular due to their reliability and unpretentiousness. However, they need in timely service and proper storage... It is undesirable to keep these devices in rooms with high humidity. This can cause corrosion on the working surface of the stem, which in the future will lead to rapid wear of the sealing lip, then oil will start to leak. Jack you need store horizontally, so that it has an emphasis on all wheels.

They are also called "low profile". These jacks allow the lowest vehicles to be lifted to a maximum permissible height of up to 503 mm. It is equipped with more massive and durable wheels, since it is meant to be used on a daily basis. Some models are equipped with a dedicated jack lifting pedal. It allows for better regulation of the process in order to avoid sudden jerks of the machine. Otherwise, this is a normal rolling jack. The service interval for these models is very large.

For this type of jack to work, it is necessary additional equipment in the form of a compressor and high pressure hoses... In addition, the working area of ​​the product is limited by the length of the hoses. Such lifting mechanisms significantly save working space, and for lifting or lowering, you need to adjust the volume of compressed air using an air valve. To lift the car, it is necessary to open the air supply valve and close it in time, and to lower the load, it is necessary to relieve the pressure by slightly opening another valve. If the garage is small and has an air compressor, then such a product will significantly save working space.

Depending on the model, this type of rolling jack has long handle, which allows you to roll the device under the middle of the car and raise the front or rear. Thus, each type of work has its own type of pneumatic jacks. Such products have the most main advantage Is the lifting and lowering speed.

Choosing a rolling car jack is not as easy as it might seem at first glance. First you need understand where and in what conditions this tool will be used. It should be remembered that rolling devices need a solid and even surface, if there is none, then this type of jack will not work. When you have decided on the type and lifting capacity of the jack, you need to choose its minimum and maximum height. With each new generation of cars, they are getting lower, so it is better to choose devices with a low profile of 90 or 100 mm. The maximum lift must be higher than the vehicle's suspension travel.

The next important fact when choosing a jack is its length is in working order. This value is important for those who work with these devices in a small garage. You need to install the jack strictly perpendicular to the vehicle, your lifting device must fit between the machine and the wall. Under no circumstances should the lift be installed diagonally to the machine. This is due to the fact that during lifting, the jack passes slightly forward (under the machine). If you start to lift the car with the jack standing obliquely, then its support wheels (not designed for such a direction of load) may break.

Choosing a rolling jack, be sure to inspect it for defects in the o-ring around the stem. The seal must be clean, free of cracks, and seated at the same distance around the entire perimeter. The device must be free of oil stains. It is best to purchase such a tool in specialized store with a good reputation for many years...
