What is a Bollard Barrier? Bollards are physical deterrents and obstacles in security system applications. Their main function is to prevent the passage of malicious individuals. Types of bollards include: Mechanical bollards, Hydraulic bollards, Pneumatic bollards, and Manual bollards. Bollards are road bollards that emerge from the ground by a mechanical, hydraulic, or pneumatic action. Hydraulic and pneumatic bollards have a piston inside the bollard; hydraulic oil or air from a unit moves this piston, thus operating the bollard. Mechanical bollards have a motor and gears inside the bollard that enable its movement. These gears open or close the bollard. In hydraulic and pneumatic bollards, the motor and tanks (air and oil) are housed in a separate cabinet outside the bollard. Hydraulic or air hoses distribute the oil to the bollards. Almost all mechanical barriers are enclosed within a bollard. Bollard barriers are used in areas with traffic today, such as pedestrian zones, parks, etc., to prevent vehicle traffic without hindering pedestrian movement. These specially manufactured bollard barriers are produced using special anti-assassination steels, considering the safety of life and property. Our company's specially designed Assassination Bollard Barrier is specifically engineered to prevent car bomb attacks and suicide attacks using vehicles.
