It is probably hard to find a person who does not know what a jack is. This important tool allows you to lift, as necessary, not only cars, but also other equipment. A rolling jack is perhaps the most popular of all types of these devices. It is used to raise and briefly hold vehicles at a set height. A rolling jack is also used to lift various loads.
Device Information
There are several
types of jacks, the most common of which are pneumatic, hydraulic, mechanical, rack, screw, wedge and air. Each of them has its own differences. Some of them are fast, others are light, some have a smooth ride, while others are of lesser cost. Despite the different characteristics and features, a rolling jack is especially popular among similar devices. It relates to hydraulic equipment. The
bottle jack also belongs to this group
. Hydraulic hoists have maximum load capacity, high lifting height, stability and reliability.
The jack was invented by the auto repairman P. Lunati back in 1924. A year later, the same person created a platform lift with a hydraulic stand in the center. When choosing a car tool, you should focus on the following indicators: maximum load capacity, reliability, stability, lifting height. The rolling jack is most in demand among motorists, because for all its simplicity it is in many ways superior to its counterparts. It is characterized by a relatively low body with wheels, which allows it to penetrate under lowered vehicles and loads. A lever with the so-called "lifting heel" rises from the housing, thanks to which lifting is carried out directly. A rolling car jack may have removable platforms that provide maximum convenience when working with this device.
Rolling Jack Groups
This equipment is divided into 3 groups:
- used for personal needs of a motorist (load capacity up to 3 tons);
- used for work in car services and tire workshops (up to 4 t);
- used for servicing special equipment (forklift trucks) and heavy vehicles (load capacity up to 20 t).
The rolling jack is often equipped with a pre-lift pedal. Some of the models involve the use of a sliding beam to lift the car on one side.

This small but very comfortable jack is most often used by ordinary motorists who have cars that are not too large. This lifting equipment will serve the owner for more than one year. It is quite compact and does not take up much space. Such a rolling car jack is also good in that the lowering and lifting is performed without jerking, very smoothly and evenly. This is due to the fact that the
hydraulic oil inside it is a practically incompressible fluid. Its main drawback can be considered that it works slowly, it will annoy those who are in a hurry somewhere.
