The Role and National Standards of Anti-Terrorism Lifting Columns
Anti-terrorism lifting column, also known as crash-proof bollard, protective post, warning post, and reflective post, is divided into fixed and movable types, with the purpose of preventing accidental collision of motor vehicles and providing protection and buffering effects. Crash-proof bollards are mainly used at entrances and exits, highways maintenance, hotels, residential areas, sports facilities, risk areas, and road construction sites. Crash-proof bollards refer to devices installed behind parking spaces to prevent vehicles from reversing and colliding with other vehicles. They are made of high-strength rubber that is vulcanized under high pressure, with good compression resistance. They are black and yellow in color and contain reflective materials, making them visibly eye-catching. They also have characteristics such as deceleration, skid resistance, wear resistance, and reducing tire wear of vehicles. Wheel stopper devices are installed behind parking spaces to limit the position of vehicles and the ramps have flexibility to reduce tire wear.
They are composed of steel pipes and flanges. The outer surface of the steel pipes is covered with yellow and black reflective film to achieve a reflective warning effect, attracting the attention of vehicles and people. They are used in residential areas, gardens, and other places. Crash-proof stainless steel bollards can also be installed in temporarily open areas to solve temporary exit problems. They can be customized in various specifications. Reflective movable crash-proof bollards are suitable for areas such as residential areas and parking lots where vehicles are prohibited, effectively blocking vehicles. The crash-proof bollards are covered with reflective film, which can alert drivers to obstacles ahead even at night, preventing accidents. They are detachable and have a key control on the ground part, allowing them to be installed and removed according to the actual situation. Various specifications of crash-proof bollards can be customized.
Movable crash-proof bollards can be removed or installed according to the needs. They are equipped with a lock device that can be locked when blocking is required. Fixed crash-proof bollards do not have a lock device and are disposable. The installation of movable and fixed crash-proof bollards depends on the ground conditions to determine whether a pre-embedded base is needed.
Stainless steel bollards are made of seamless steel pipes, which are sturdy and elegant. The surface of the steel pipes is treated with high-pressure spraying and engineering-grade reflective film. The outer surface of the steel pipes is covered with yellow and black reflective film to achieve a reflective warning effect, attracting the attention of vehicles and people. The product is easy to install. Crash-proof bollards are divided into fixed and movable types and are composed of steel pipes and flanges. The bottom of the crash-proof bollards is fixed with steel nails or screws, ensuring that the devices are strong and reliable and will not loosen when vehicles collide with them.
Safety lifting columns are colored yellow to indicate warning and attention. Safety colors convey the meaning of safety information and include red, blue, yellow, and green. According to regulations, safety colors are applicable to industrial and mining enterprises, transportation, construction, as well as warehouses, hospitals, theaters, and other public places. However, they do not include lighting, fluorescent colors, and colors used for aviation, navigation, and inland waterway transportation. The national standard specifies four safety colors for conveying safety information: red for prohibition and danger, yellow for warning and attention, blue for instructions and compliance, and green for passage and safety.
