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.
Auto-close of the boom barrier can be programmed through the controller using Induction loop or Photocell. Duration of fast and slow speeds is programmed at the time of installation according to the length of the boom and frequency of traffic expected.
