Semi-Automatic bollard is suitable for higher security but low frequency access control system. Proceed from the econ-omy,it is usually used together with automatic Bollard, it has higher security protective effect and avoid of complex High/Low Voltage construction. As the safety requirement increased, the bollard size becomes bigger, the air pressure assis-tant system of Semi-automatic Bollard will afford more load.The decline process of Semi-automatic bollard is realized mainly by operator’s press. When the top of cylinder reach the ground level, the mechanical lock by itself, the rise of Semi-Automatic bollard is realized **0% by the air pressure assistant system of Semi-automatic. After use the special key to lose the lock, the cylinder will rise automatically to a certain level and locks automatically.
The recommended Semi-Automatic bollard maximum install spacing is 1.4M, the depth of excavation have to depend on the different specifications cylinder. For special needs please contact local dealers.
