Antiterror rising bollards – article of Detektor bollard part 1.
„A bollard which is qualified K4 means a 2-ton car with 57 km/h speed will be able to stop it and the bollard is able to work partly….”
Orion21 Ltd. has the main profile the distribution of rising bollards. Our product is produced by Italian PILOMAT s.r.l., whit whom we have been working together for a long time ago. In addition to bollards produce the Pilomat road blockers, chain barriers, parking barriers, tire killers, and other street blockers. In this article, we would like to show the rising bollards, especially that columns which are qualified with anti-terror countermeasures.
This anti-terror bollards can be used our company several high-risk location with successful. Our system can be found in the main entrance of specialized service, by emphasized government buildings, by the Budapest International Airport and public domains. Our anti-terror bollards have the following qualifications: K12 (American cert. DOS SD-DT 02.01), M50 (ASTM cert. – F2625-07), K4 (USA), M30 (ASTM cert. – F2656-07), and besides that the tools have PAS68 and IWA14 with certifications. These systems have passed successfully resistance level.
ABILITIES
The above things, what does it mean exactly in practice?
Our company’s anti-terror bollards are capable of stopping specific vehicles from impact energy of 250 000 Joules from the impact energy of 750 000 Joules to 700 000 Joules of impact energy to 2 000 000 Joules. In everyday language it means: a K4 qualified rising bollard, a 2-tonne car will still be stopped at 57 km / h, with the column partially capable of running, while at a speed of 98 km / h the column will suffer significant damage, it can even break out of its place, but it stops the vehicle. For a 6,8 ton truck, these speed ranges will change to 31 km / h and 53 km / h. By the 120 cm high K12 qualified rising bollard these values are modified as follows: that car with 95 km/h speed is able to stop the car the bollard without any damage, but 161 km/h will suffer heavy damage, maybe can even break out but it stops the car. In the case of truck (6,8-ton) at 52 km / h, the bollard suffers minimal damage, while at 84 km / h it is still able to stop the truck, but significant damage can also occur. Good to know, after one a sharp test such a qualified bollard, a 7-ton truck hit with an 80 km/h after hitting the bollard bent only a few degrees but still remained functional.
It is important to mention that the rising bollards are built on a modular system. The essence of this is that after an impact it is not necessary to replace the whole device at the same time. It is enough to replace the damaged elements (mantle, possibly other moving parts) and the system will be ready again for the protection level that was previously used.
If we take into account the regrettable tendencies of the past few years, which showed that terrorists can turn any vehicle into a deadly weapon and that dozens of lives can be sacrificed in minutes, so it is clear that such attacks need effective protection and antiterror columns appropriate solution. Unfortunately, concrete blocks creat in public areas only the illusion of security.
There have been a number of recent cases that have proved that these solutions are not capable of performing their tasks, and even the motive energy of the vehicles driving them is only pushing them away, so that uncontrolled concrete blocks will dislodge everybody on their way and „help” the attackers to further harm and take victims.
