A hydraulic lift is a device that is found in almost every service station and car service. Thanks to the use of this installation, you can quickly and efficiently perform maintenance work on the vehicle. However, in addition to this, there is a hydraulic lift used for municipal purposes and in construction. Most often, it is placed on the chassis of a car and lifts from 2 to 5 people (depending on the type and design of the device). You can find out exactly what hydraulic lifts are and how they are arranged from the article below.
What are they?
Any hydraulic lift is characterized as a load-lifting device, the platform of which moves with the help of a special electro-hydraulic drive. The latter consists of a pump that pumps the working fluid, and a hydraulic cylinder, where, in fact, this fluid ends up. This device operates very smoothly, which allows lifting the platform without any jerks. At the same time, the speed of the mechanismhigh enough.
Varieties
Currently, the following types of devices are distinguished:
- 2-rack.
- 4-rack
- Scissor.
So, let's find out what each of these mechanisms are.
Two Posts
These devices can be seen at car service stations. The two-column hydraulic lift combines such qualities as low price, high productivity, reliability and unpretentiousness in service. In addition, this device is characterized by an extensive set of functions.
The main mechanism in the operation of this lift is a hydraulic cylinder, which is most often mounted in one of the racks and driven by an electric motor. However, that's not all. More expensive options are equipped with several cylinders installed in each of the racks. This design has an increased load capacity, and all units that are involved in lifting the load are very reliable and productive.
Four rack units
This hydraulic lift is also used in the automotive service industry. However, if the first type is most often used to lift passenger cars, then the four-post mechanism, due to its increased efficiency and load capacity, is used to lift long-wheelbase vehicles, trucks, buses and heavy jeeps. Despite their excellent technical characteristics,the four-post hydraulic lift also has disadvantages, mainly related to dimensions and cost, which does not allow it to be used in all car services today.
Hydraulic scissor lift
This is the most practical and functional lifting mechanism. Its high cost is more than offset by its excellent load capacity, compactness and extensive feature set. Most often used to adjust the wheel angle (alignment) on cars.
How much does a hydraulic lift cost?
The price of these devices directly depends on the type to which they belong, and can range from 50 to 220 thousand rubles.
