BL 45A/F

The BL 45A/F barriers are from the technology of the BL 4x range and are associated with accessories recommended by the French Tunnels Study Centre (CETU).
The BL 45A/F barriers are particularly suited to securing roads such as bridges, tunnels, crossings, mountain passes, etc.

Main benefits:

  • Closing off wide lanes
  • Low maintenance costs


  • Investment for long life cycle


Pivoting base

The pivoting base positions the barrier parallel to traffic lanes to facilitate drive and periodic tests without affecting traffic. This device also limits damages caused by a slight shock by freeing the barrier's rotation via the failure of an adapted part. Position sensors indicate the housing position.

Automatic locking

The boom remains locked in the open position thanks to a robust mechanical system allowing a firm locking of the arm. This functionality guarantees that the boom is held in the open position even in strong winds.


  • Traffic management
  • Bridges and tunnels
