A boom barrier, also known as a boom gate, is a bar, or pole pivoted to allow the boom to block vehicular or pedestrian access through a controlled point. Boom gates are often counterweighted, so the pole is easily tipped. Boom gates are often paired either end to end, or offset appropriately to block traffic in both directions. Some barriers also feature a pivot roughly half way, whereas the barrier is raised, the outermost half remains horizontal, with the barrier resembling an upside-down L when raised.
There are various technologies for an automatic boom barrier. One of them is electro-mechanical, which is widely used due to its reliability. The other technologies are often manufacturer specific. These electro-mechanical devices come with 24VDC drive units which can run continuously without generating heat, so electro-mechanical boom barriers can be operated continuously and in an intensive duty cycle.
An automatic boom barrier can be operated through:
- Push button
- Remote control
- RFID tags / RFID reader
- Loop detectors
- Optical electronic sensors
- Any third party access control device
Boom gates are typically found at level crossings, drawbridges, parking facilities, checkpoints and entrances to restricted areas. They are also the usual method for controlling passage through toll booths, and can also be found on some freeway entrance ramps which are automatically controlled to drop to restrict traffic in the event of accident clean-up or road closures without the need to dispatch road workers or law enforcement to use a vehicle to block the way. Some boom gates are automatic and powered; others are manually operated. Manual gates are sometimes hung in the manner of a normal gate (i.e. hinged horizontally). In some places, boom gates are installed across suburban streets as a traffic calming measure, preventing through traffic, while allowing authorised vehicles such as emergency services and buses to take advantage of the shorter and more direct route.
Flap Barrier are designed to provide access control and complete security in the public passages. It demotes to the way out of the security dilemma, and it provides the safety and security to the employees of an organization and also to the assets in a business. At the same time, it gives a high level of access to the open public and to the visitors. This has a big benefit for the people whose entire revenue depends on a constant pedestrian flow while safeguarding and securing its assets and personnel at a time.
Flap Barrier is the automatic gates you will find on the stations, office entrances, airports and also in other many places. In is a device for emergency controlling. This allows an automatic opening of its two wings while people connect with it with the access cards and close down in a minute after that.
