What are the classification of lifting columns according to their working principles

1. Pneumatic fully automatic lifting column: Air is used as the driving medium, and the column is driven up and down through an external pneumatic power unit.
2. hydraulic fully automatic lifting column: hydraulic oil is used as the driving medium. There are two control methods, namely, driving the column up and down through the external hydraulic power unit (the driving part is separated from the column) or the built-in hydraulic unit power unit (the hydraulic lifting column movement).
3. Electromechanical automatic lifting: the lifting of the column is driven by the motor built into the column.

Semi-automatic lifting column: The ascending process is driven by the built-in power unit of the column, and it is completed by manpower when descending.

4. Pull-up lifting column: The lifting process requires human lifting to complete, and it depends on the weight of the column itself when descending.
5. Movable lifting column: the column body and the base part are separated design, and the column body can be put away when it does not need to play a control role.
6. Fixed column: The column is directly fixed to the road surface.

Different types of lifting columns have different adaptation places. For example, some places with high security levels, such as military bases, need to use anti-terrorism lifting columns, and the thickness of the column generally needs to be more than 12mm. The general civil level lifting column is 3-6mm, which is suitable for vehicle access control places with large traffic volume and medium safety requirements. It is widely used in banks, government agencies, R&D centers, power stations, highways, industrial parks, high-end villas, high-end office buildings, luxury stores, pedestrian streets and other places.
