How to choose a jack
If you need to choose a quality jack, then Nordberg fully meets all expectations. When you need to purchase a tool for a car service or workshop, then rolling models are ideal.
Such units are very maneuverable, despite their weight, and are very small in size. And another plus is rolling the jack on the floor, rather than manually transferring it.
For home use, hydraulic models such as bottle jacks are better suited. They are capable of working both indoors and outdoors. Also, such models are not afraid of rain or snow. They are versatile, since such units can be installed even on an uneven surface. Therefore, these types of jacks are better suited for the road. Mechanical models are also suitable, and besides, they are very cheap (1-3 thousand rubles), but they are not as good as hydraulic ones.

Advantages and disadvantages of a rolling jack
The main advantages of sliding hydraulic lifts include:
- High efficiency value.
- Good carrying capacity with small dimensions of the device. This is made possible by the horizontal arrangement of the cylinder and the removable handle.
- Smooth movement of the lifting mechanism. The stock moves very neatly, slowly raising the car to a sufficient height. Due to the presence of a shut-off valve, the load is secured at any lifting height.
- Excellent stability due to the large support area.
- The convenience of use.
- Cleanliness of work. There is no need to lie under the car, as is often the case with other types of jacks.
The disadvantages of a hydraulic lifting mechanism are:
- Slow ascent, since it is possible to raise the car to a small height in one cycle. While smooth ascent has been considered a virtue, speed is sometimes necessary.
- The pressure in the main cylinder can be relieved and the load can be lowered.
- In winter, at subzero temperatures, the hydraulics freeze. Although for off-season rubber changes this is not particularly critical, as, indeed, for work in a car service or a garage with heating.
- Expensive repairs and short service life. Without periodic maintenance and with improper operation, the structure becomes insufficiently durable.
- Needs costly ongoing maintenance.
- Low lifting height.
- When operating this kind of mechanisms, a flat solid surface is required: concrete or asphalt.

The model is very compact, simple and reliable in operation. With a little physical effort, the load is lifted smoothly, and during its use, no auxiliary devices are required.
Criterias of choice
The jack must be in the trunk of every vehicle. But in order to choose a suitable model, it is necessary to outline some criteria.
- Jacks with a small load capacity, which lift from 1 to 2 tons, are intended specifically for light vehicles.
- Models of jacks with medium lifting capacity, which are capable of lifting from 3 to 8 tons, are used in auto repair shops. This includes rolling jacks and bottle jacks.
- Heavy-duty jacks, which are capable of lifting loads from 15 to 30 tons, are designed for trucks and trucks. As a rule, these are hydraulic and pneumatic mechanisms.
In order for the jack to be easy to use, it must have metal wheels. They are much stronger than other options and are not subject to mechanical stress. It is very good if the kit includes a carrying handle. In order to be able to substitute the jack under any point on the underside of the car, a rubber pad must be included in the kit. Thanks to it, you will soften the pressure of the device on the body of the equipment and prevent dents.

The range of the brand includes rolling jacks, bottle jacks, pneumatic and pneumohydraulic jacks, as well as jacks for moving a car.
Pneumatic jacks can also be called glass jacks. They are necessary if there is a small gap between the load and the support. Jacks of this type are often used during repair and installation work. They are a popular tool among motorists, have a high cost, but when working with them, a minimum of physical effort is required from a person. The high cost of these devices directly depends on the complexity of their design, since all joints are highly sealed, as well as an expensive technology for the manufacture of their sealed shells. Such jacks are a structure that is equipped with a rubber sole.
