1. In view of the confusing types of lifting columns, various styles have been expanded. The main categories are: 
The main use occasions, advantages and disadvantages of various types of cylinders are different, and they need to be selected for the actual project when they are used. For some high security level applications, it is necessary to use anti-terrorism level lifting columns. Compared with the general civil grade lifting column, the thickness of the column body generally needs to reach 12mm or more, while the general civil grade lifting column is 3-6mm. As for the civil grade lifting columns, although the performance is slightly worse than the anti-terrorism class lifting columns, its protection can fully meet the frequent needs of civil security in daily life. In addition, the installation requirements are also different. 
Hydraulic automatic lifting columns are widely used in parking lot entrances
As a common public facility, the lifting column plays an important role in our daily life. It is suitable for vehicle access control places with large traffic volume and medium safety requirements. It can be widely used in banks, government agencies, research and development centers, power stations, highways, industrial parks, villas, office buildings, boutiques, pedestrian streets and other places.
1. Pneumatic full-automatic lifting column: Air is used as the driving medium to drive the column to rise and fall through the external pneumatic power unit.
2. Hydraulic automatic lifting column: hydraulic oil is used as the driving medium. There are two control methods, namely, the external hydraulic power unit (the driving part is separated from the cylinder) or the internal hydraulic unit power unit (the driving part is placed in the cylinder) to drive the cylinder up and down.
3. Electromechanical fully automatic lifting: the lifting of the cylinder is driven by the built-in motor of the cylinder.
4. Semi-automatic lifting column: The ascending process is driven by the built-in power unit of the column, and it is completed by human power when descending.
5. Lifting type lifting column: the lifting process requires manual lifting to complete, and it depends on the weight of the column body when descending.
6. Movable lifting column: the column body and the base part are designed separately. When the column body does not need to control, it can be retracted.
7. Fixed column: The column is directly fixed to the road surface.
As we all know, the situation of domestic fans has been strengthened, and the protection of important buildings is particularly important. The lifting column is being accepted by more and more users due to its many advantages such as safety, beauty, strong collision resistance and so on.
