Main parts of the jack
The design of the hydraulic type jack is characterized by a large number of advantages and some disadvantages. The hydraulic jack scheme provides for the following elements:
- Housings. In its manufacture, a material is used that is characterized by corrosion resistance and strength. It should be borne in mind that the body has the dimensions of the stem.
- A working chamber that has a mirrored surface.
- Piston being pressured. It consists of several different seals assembled into a single unit.
- A special valve that restricts the movement of fluid.
- Manual or automatic movement capable of propelling oil. To apply pressure, the oil must be pumped from the storage chamber to the working chamber, for which pressure must be created.
Repair and maintenance is possible only when the structure is collapsible. On sale there are models with a non-separable mechanism, which belong to the category of unattended devices.
The main advantages of the mechanism under consideration include the following points:
- Ease of operation. In order to activate the mechanism, it is enough to put a load on the lever.
- High power rating. With its compact size, the structure is able to withstand quite a lot of pressure.
- The efficiency value is 80%. This indicator largely determines the distribution of such lifting structures.
- Common versions are designed for loads up to 10 tons. On sale you can find versions with a lifting capacity of about 200 tons.

However, there are quite a few serious disadvantages that must also be taken into account. These include the following points:
- There is no way to lift a load from a low height. When choosing a suitable model for a car, its ground clearance should be taken into account. Otherwise, many difficulties may arise with the use of the device.
- It is impossible to control the level to which the load will fall. At the same time, the load is lowered at a high speed, which is practically impossible to control.
- Only with periodic correct maintenance can the device in question be able to serve for a long period. An example is work related to the replacement of oil seals and oil. The gaskets can also wear out over time.
- Store and transport only in an upright position. This is due to the fact that even with a high tightness index, there is a possibility of operating oil leakage.
- The rise is carried out in cycles, there is no smoothness in the course.
- Due to the use of expensive materials and the complexity of their processing, the cost of a hydraulic jack is quite high.
- Small indicator of maintainability. If the housing or the working chamber is severely damaged, it can be difficult to repair. In addition, service can be carried out exclusively in specialized centers. The cost of repair and maintenance can be quite high.
Rolling hydraulic jack
On sale there are a variety of options for the execution of lifting mechanisms. The most widespread are bottle-type units, since they are compact and designed for a load weighing up to 100 tons. Roll-ups can be found in workshops and service stations, rhombus are also suitable for use in a car service. There are also hybrid versions, which are characterized by high efficiency.
How to choose?
Choosing an automobile rolling jack should be primarily based on the purpose of use.Most motorists need it for ad hoc repairs and minor maintenance. For this, household (or "amateur") jacks, discussed in the "Rating" section, are enough. The determining factor here is the price-quality ratio. All of these devices fully meet this ratio and, with some fluctuations in quality, are suitable for any passenger car except SUVs. Bottle jacks or rack jacks are recommended for all categories of SUVs.
Professional rolling jacks are required to work in auto repair shops. They have a much greater resource, carrying capacity and height.
