Q. How many different kinds of boom barriers are there?

Answer

Basically, there are two types of boom barriers- automatic and manual. Boom barriers are automated security gates that have superseded their manual predecessors. Automatic boom barriers are necessary for light of the recent trend toward the digitization of road traffic management systems and other formerly analog processes. A boom barrier consists of a barrier arm that can swing out from a stationary base. AC motor, gearbox, locking plunger, and balance spring are only a few of its features. The AC motor is powerful enough to raise the fixed barrier arm, and it travels vertically. The counterweight channels are rotated from a horizontal to a vertical orientation and back again when power is supplied to the motor, which in turn turns the gearbox.
