A boom barrier, also known as a boom gate, is a bar, or pole pivoted to allow the boom to block vehicular access through a controlled point. Typically the tip of a boom gate rises in a vertical arc to a near vertical position. 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 boom gates also have a second arm, which pivots on links that allow the second arm to hang 300 to 400 mm below the upper arm when it descends into the horizontal position, to increase approach visibility.
Automatic Boom Barrier
There are various technologies for Automatic Boom Barrier and Out of them Electro- Mechanical is one of them, which is a widely accepted technology and a full proof technology also. rest of other technologies are just manufacturer specific only. These electro mechanical device comes with 24VDC Drive unit which can run continuously without generating heat, so electro-mechanical boom barrier can be operated Continuously. These electro mechanical boom barrier can be use in Intensive Duty Cycle.
Operation / Integration of Automatic Boom Barrier
An Automatic boom barrier can be operated through
- Normal Push Button - Beninca Push Button
- Remote Control
- RFID Tags / RFID Reader
- Loop Detector
- Any third party access control device.
Automatic Boom Barrier being installed on main entrance / gate is vulnerable / prone to accident, so nowadays boom barrier comes with LED LIGHT ON ARM OF BOOM which keeps on blinking even in closed position and user or the passerby get notic that some obstacle is there on gate. Still if some vehicle hits barrier, the user can not make an excuse that he was not able to see the barrier. So use barrier with LED LIGHT ON ARM to Avoid accident. All Beninca Barrier comes with Led light on arm. Also Photocell Safe beam is used for Safety purpose.
There are various OEM for Automatic Boom Barrier, out of which some famous OEM is Beninca SpA, Italy etc.
Boom gates are typically found at level (rail) 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 cleanup 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.
