How can we choose bollards to solve the problem of excavation depth?

If we don't want to dig so deep and still want to control anti-terrorist vehicles, do we have a better choice? Generally, the excavation depth of ordinary hydraulic lifting columns is 800mm. In case of underground pipelines and other issues, can the pre-embedded depth be shallower? With a pre-embedded depth of 470mm, we can choose a two-stage pneumatic lifting column.

The two-stage pneumatic lifting column is a new product developed and customized for places that cannot meet the excavation depth. Installation can be completed with only a 470mm excavation depth. This excavation depth is less than half of similar products and is very suitable for scenarios above underground parking lots and where underground pipelines are complex and deep excavation is impossible.

The pneumatic lifting column uses compressed air as the driving medium. The system is mainly composed of an air pump, cylinder, solenoid valve, etc. Compared with hydraulic and electric lifting columns, the pneumatic lifting column has superior operating performance, is environmentally friendly and durable, has low maintenance costs, and strong driving force. Using PLC to control the rising and falling of the movable column is fast and stable in operation. The intelligent control system can realize a variety of optional functions and can also be linked with a computer to achieve remote central control and mobile APP control. It has complete functions and stable performance. Optional components include: ultra-high-energy LED warning lights, equipment status display devices, vehicle detection devices, automatic detection heating devices, etc.
