Traffic Bollards …or How To Stop a 10 Ton Truck Instantly
You know those thick concrete poles they put up in front of the doors to shopping centers to keep trucks from doing a smash and grab job by driving through the doors? Wussy! That’s right, those things don’t hold a candle to the ultimate traffic bollards that have now been developed which are essentially giant steel poles!
The video below demonstrates what would happen to a large truck filled with… well, anything you didn’t want to get through if it attempted to actually barrel it’s way on through one of the moveable barricades. It is absolutely devastating. Check it out…

The metal on the front of the vehicle almost bended in the way that liquid would around a solid object. The strength of the beam does appear quite high, and one would wonder if a battering ram of steel at the speed of the truck would be able to knock it off its base.
Wow. I wonder how those posts are so firmly affixed in the ground that they can withhold such momentum. That is simply amazing.
holy crap! i really didn’t think it would work like that. the federal reserve bank down by wall street has a whole row of these retractable bollards at the entrance to their garage — along with many well-armed uniformed men.
Holy smokes!! I always wondered if these things were actually effective. I’d say they are much more than effective. A complete barrier to anything getting through!
OMG, that’s freaking amazing!!!!
“shower of DAYbree” Love that!! heehee!
That’s absolutely insane. I’ve seen the concrete versions throughout my life, much of the time they are broken 2/4 of the way up and simply repainted (somewhat defeating the purpose). Recently I have seen these retractable versions near important historical or government buildings here and abroad. I figured it was simply an alternative to a gate; functioning to deter those who do not belong from entering. I never realized they were also a defense mechanism…
