Rising Bollards, also known as lifting pillars, lifting piles, anti-collision piles, hydraulic Rising Bollards, isolation piles, etc. Rising Bollards is widely used in many occasions such as city traffic, military and national key organs and surrounding gates, pedestrian streets, highway toll stations, airports, schools, banks, large clubs, and parking lots. By restricting passing vehicles, the order of traffic and the safety of major facilities and places are effectively protected.
Overview
Rising Bollards, also known as lifting pillars, lifting piles, anti-collision piles, hydraulic Rising Bollards, isolation piles, etc. English name Bollard. The term Bollard was originally coined to describe a short, vertical column that was frequently used by large port ships when they were parked. Now its meaning has been expanded to describe various management of pedestrian traffic, protection of critical infrastructure, establishment of perimeters, and differentiation of road facilities.
According to legend, the street guardrail began in the 17th century and is shaped like an inverted cannon, used as a boundary setting and city sign. Since then, they have appeared more and more in our daily lives, everywhere, such as supermarkets, restaurants, hotels, shops and stadiums. We can often see bollards of various shapes, or use them as a reminder of the direction of travel, or to protect us against injury, or to tell if we can park here. These beautifully shaped bollards have beautified the environment, distinguishing between the sidewalks and roadways, and sometimes even serving as chairs for us to sit down and enjoy lunch.
Fixed metal bollards are the most common. They are generally high-strength columns of painted steel bars, internally cemented and installed on the ground. Some bollards are cubes, but most are cylindrical structures with angled or flat caps. The size, color, texture, shape and function of bollards are numerous. They are fixed, or can be moved, or stretch freely, and can also be used as an ornament to decorate the original steel bollard.
Many bollards have aesthetic functions, especially metal bollards, which are used to prevent vehicles from damaging pedestrians and buildings. They can be used as the simplest way to control access, and can also be used as guardrails to define specific areas. They can be individually fixed on the ground, or they can be lined up to close the road and prevent vehicles from entering, thus ensuring safety. Metal fences fixed to the ground serve as long-term fences, while retractable movable fences ensure access to vehicles of certified people.
There are three main applications for bollards: building (decoration), safety (impact resistance) and landscaping (prominent perimeter). All bollards can be used in architecture and landscape landscaping. They differ only in style, shape and material. When it comes to safety applications, different bollards are used to block different objects. For example, the bollards used to stop traffic are different from the bollards used to handle protection (shock) problems. When it comes to safety applications, you must first consider the size of the vehicle and the speed of the vehicle at the time of the impact.
After years of application development, bollards have expanded into various styles. Its main classification:
1, Pneumatic full automatic Rising Bollards: air as the driving medium, through the external pneumatic power unit, driving cylinder up and down.
2, hydraulic automatic Rising Bollards: hydraulic oil as a drive medium. There are two control methods, namely, the cylinder is driven up and down by an external hydraulic power unit (the drive part is separated from the cylinder) or an internal hydraulic power unit (the drive part is placed in the cylinder).
3, Electromechanical automatic lifting: Through the column built-in motor drive cylinder up and down.
Semi-automatic Rising Bollards: The ascent process is driven by the built-in power unit of the column, and it depends on the manpower for the descent.
4, Rising Bollards: The ascent process requires human pull to complete, depending on the weight of the cylinder itself.
5. Removable Rising Bollards: The column and base are separated and designed to be stowed when the column does not need to control.
6, fixed column: cylinder directly with the road fixed.
The main use occasions and advantages and disadvantages of various types of cylinders are different, and they must be selected according to the actual project when used.
For some high-security applications, such as military bases and prisons, you need to use the Rising Bollards. Compared to the general civilian grade Rising Bollards, the cylinder thickness generally needs to reach 12mm or more, and the general civilian grade Rising Bollards is 3-6mm. In addition, the installation requirements are not the same. At present, there are two internationally recognized standards for high-security anti-terrorism lifting piles: First, the British PAS68 certification (to meet the PAS69 installation standards); Second, the United States Department of Foreign Affairs Security DOS certification. The 7.5T truck was tested at a speed of 80 KM/H. The truck was stopped in place, and the roadblocks (Rising Bollards, road piles) worked as usual.
For civilian-grade Rising Bollards, although the performance is slightly worse than the Rising Bollards of the anti-terrorist level, its protective performance can fully meet the needs of civilian security and is used frequently in daily life. It is suitable for vehicles access control places with large traffic volume and medium safety requirements. Can be widely used in banks, institutions, research and development centers, power stations, highways, industrial parks, luxury villas, high-end office buildings, luxury goods stores, pedestrian streets and other places.
With the strengthening of the domestic anti-terrorism situation, the protection of sensitive areas in buildings is particularly important. Rising Bollards is being accepted by more and more users due to its many advantages such as safety and aesthetics. However, Rising Bollards' products have entered the Chinese market with a short period of practice, with less market accumulation and feedback, and the demand has suddenly expanded. The products on the market cause miscellaneous things, and it is not uncommon for products to be shoddy and shoddy. A large number of users and integrators have become victims of the profits of certain bad businessmen.
Fold edit the classification of the use of this paragraph
Fully automatic Rising Bollards
Rising Bollards taking off and landing can be done automatically by lawful authority information, automatic door Rising Bollards also Rising Bollards major equipment manufacturers of products, generally used in landing more frequently, and there are certain places around the security forces.
Semi-Automatic Rising Bollards: to lock or release the Rising Bollards manually key when the device is in the raised state, through artificial foot down after the key is released, automatically locked in place by releasing the key will automatically rise again, the Most products are used in places where there is little need to take off. Or there is no place where there is no place for security. One of the main reasons is the low construction cost of the semi-autonomous province, and the second reason is that the semi-automatic Rising Bollards have no control panels or control cabinets with high security against theft. For example, walking streets, squares, and other places can be selected, and in addition, some wide entrances and exits can be used with fully automatic Rising Bollards.
Fixed bollards: The upper section of the road surface is the same as the fully automatic/semi-automatic Rising Bollards and has the same material but cannot be active. It is mainly used with automatic/semi-automatic Rising Bollards.
Moving road piles: No deep burial is required, and parts on the ground can be manually removed and removed. It is mainly applicable to some places with small traffic and staff guards. Due to the need to move, the general body of the reclassification is smaller and lighter, and it mainly serves as a schematic effect and weak impact resistance.
