MVB, the barrier that is a nightmare for drivers who jump the barriers
Mifram Security MVB is a modular barrier capable of stopping 40-ton trucks dry, without destroying the vehicle or overturning it.
The police or security barriers they have a dissuasive character. They are designed to change the mind of those who want to skip a police checkpoint or enter a restricted area. But if the vehicle accelerates towards them, since they are usually made of plastic and are nothing more than pilings, they can jump or break it without stopping.
The Israeli company Mifram Security has been manufacturing safety barriers since 1962, and ensures that its MVB barriers with insurmountable, stopping trucks up to 40 tons in their tracks.
Another important feature is that they neither destroy nor overturn the vehicle, thus guaranteeing the life of the driver. You can see that they really work in this spectacular video:
According to the manufacturer, these types of barriers would have prevented terrorist attacks in which a truck or van rammed pedestrians, as occurred in the attacks in London, Barcelona or New York a few years ago.
The key to the MVB barriers (Modular Vehicle Barrier) is its L-shaped design. Thanks to it transform the horizontal moment with which a vehicle moves into a vertical moment, pushing him hard into the sky and toward the ground to stop him.
Another important feature in that they have pointed endings. When a vehicle hits them the barrier falls backwards but the lower part rises upwards, hooking to the underside of the vehicle. This lifts it upward, changing the direction of the thrust. But thanks to the barrier being attached to the chassis, the vehicle does not overturn. That is why it is considered a non-lethal barrier.
Thanks to this design, the MVB barriers, despite being made of plastic, they can stop a truck weighing up to 40 tonnes dry.
And since they are modular, they can be assembled and ginned by a single person, and they adapt to the size you want.
They have been in operation for years. They have been used in several Olympic Games, in the protection of the President of Israel, and are used by the American army and police, the United Nations, as well as several airports and train stations.
