There’s a good reason why we need boom barriers. Boom barriers are a pivoted pole or bar that acts as an ‘appendage’ to block vehicles from eventually accessing specific controlled points in a certain area. Also known as a boom gate, they’re commonly seen in contexts, such as business buildings, high security buildings and other types of primarily private property. A boom barrier is best characterized by its appearance as a large pole or beam that’s attached to a larger device at its furthest end. The opposite end of the boom barrier sits on support at the other end of the device. When in operation, the barrier lifts up and allows vehicles (and, sometimes, people) to pass through safely.
Some boom barriers use manual controls, though most use purely automatic controls nowadays. Boom barriers ultimately help block traffic and other vehicles from entering blocked off places. The need to control traffic in certain places is a big reason why many places utilize boom barriers around the world. As mentioned, boom barriers are used for a specific reason, and that reason typically involves blocking traffic from entering certain places. In other words, a boom barrier works by only allowing certain amounts of traffic into a certain place, especially if vehicles aren’t permitted to be there all at once or even there at all.
Boom barriers, or boom gates, are commonly found at rail crossings (level crossings), drawbridges, checkpoints, parking facilities, entrances to restricted areas and other places on mostly private property. You’ve probably also seen boom barriers at toll bridges, which permits vehicles and, sometimes, pedestrians to pass through after paying a fee. They’re also seen at freeway entrance ramps, which are automatically controlled to restrict traffic in the event of accidents or sudden road closures. Many of the boom barriers used in this context are automatic boom barriers.
Most boom barriers, in fact, are automatic in nature. Boom barriers from Rapid Automatic are probably the most common boom barrier used today. They’re primarily electro-mechanical devices, using both electricity and mechanical components to operate. Electro-mechanical boom barriers are so prevalent nowadays that they’re practically considered an industry standard. Boom barriers that use other forms of technology are used too, though they’re mostly proprietary and/or used exclusively by certain companies. Given the nature of boom barriers themselves, they’re pretty useful in so many contexts. As mentioned, boom barriers simply help control and restrict traffic when it’s needed, making them a pretty important device to use today.
