The sliding plate is designed to increase gradually the counter force, as the barrier moves laterally. The first movement is relatively easy and softens the forces of impacting vehicles reducing passenger injuries.
After an impact, the barrier can easily be put back into its original position.
The second movement of the sliding plate braking mechanism is activated only, when the barrier moves laterally more than 400mm and limits additional lateral movement to a maximum of 310mm.
BRIDGE-GUARD steel barrier is relatively light, which also helps to minimize static strain on bridge structures. This has been confirmed through actual crash testes. BRIDGE-GUARD is especially suitable for older bridges
