A drop arm barrier is a type of vehicle barrier that both directs and controls traffic while also providing perimeter security. These security gate arms most often utilize a steel horizontal bar to prevent access or intrusion at facility and building entry points. As such, a drop arm gate is frequently deployed in tandem with a guard house and high security fencing at strategic entrances to commercial, military and government locations. Drop arms raise vertically up to 90-degrees when engaged, either by manual, electric or hydraulic operation.
Often incorrectly used, a crash arm barrier and a drop arm are not technically the same. A crash arm refers to an anti-ram rated vehicle barrier gate that satisfies extremely rigorous testing requirements for protection against hostile vehicle attacks (HVA). A drop arm could be as simple as the drop arms encountered at a railroad crossing or parking lot entrance or exit. Protogetic has both drop arms and crash arms listed under the category "crash arms" so you can search for either anti-ram rated or unrated products more easily.
Since the 1983 Beirut Marine Barracks bombing, we have seen significant increases worldwide of Hostile Vehicle Attacks (HVAs), often employing Vehicle Borne Improvised Explosive Devices (VBIED). These terrorist threats require more robust security efforts to mitigate and/or prevent incursions at important access points. A crash-tested and anti-ram rated vehicle drop arm barrier or crash arm is an extremely effective defense to manage these hostile attacks. The goal of protective design is to mitigate and eliminate vulnerable areas in a location’s physical perimeter security. In the case of VBIEDs, crash arms and anti-ram vehicle barriers can provide increased “standoff distance” and save lives by preventing explosive devices from detonating close to people and buildings. This is one reason why Protogetic is proud to be the world's leading aggregator of crash arm barriers and high security essentials.
