The auto lifting bollard is newly launched to the public facilities with its advanced security system. Most automatic bollards could automatically lift powered by the electric-hydraulic or micro hydraulic drive system. This automatic bollard security system not only provides a higher-level security system for public facilities but also offers more convenience for passersby. This system is an ideal security system for universities, pedestrian sidewalks, parking lots, government buildings, gyms, amusement parks, airports, shopping centers, hospitals, and occasions with high traffic flow.
