Passive barriers are permanent obstacles that protect a building or property from vehicle interference.
Passive barriers have no moving parts; their effectiveness relies on their ability to absorb energy and transmit it to their foundations.
Concrete walls if properly designed and constructed, can certainly perform well as a barrier. Key elements in the effectiveness of such walls are their height, thickness, reinforcement, and foundation depth.
Terrain can be used as an effective vehicle barrier. It is difficult for certain types of vehicles to pass or traverse ditches that have sufficient width, depth and overly steep side slopes. Berms also can be effective if properly configured.
Temporary Fences and Barricades keep the job site or outdoor event enclosed by softly directing foot and vehicle traffic to a designated zone that can be broken down and set up quickly at any location at any point as needed. Typically construction sites use tall movable chain link fences to protect the public from and treacherous sections of a project.
Swing gates designs require a massive steel counterweight (many thousands of pounds) to balance the beam, and a large capacity hydraulic system to move the beam.
Upswing barrier gates can be used for a variety of commercial applications, including business parking lots, apartments, and traffic control.
Wedge barriers get their name because of their wedge shape when viewed from the side. They are also sometimes called plate barriers because the most common type uses a steel plate angled toward the approaching vehicle. This can be achieved by placing Jersey wall barriers in a way that creates a maze for the vehicle to maneuver.
This effectively forces the vehicle to slow down while permitting clearance.
