The CSG 11840 is the first crash tested, hydraulically operated bollard manufactured by Cova Security Gates.
This automatic rising bollard passed the PAS 68:2010 vehicle impact test wth the following result:
CSG 11840 Crash Tested Full Depth Rising BollardV/7500[N2]/64/90/1.0/19.4
(V/test weight[vehicle class]/speed/angle:penetration/dispersion)
The ground socket itself withstood two crash tests, enabling a new replacement rising bollard to be installed quickly following a hostile attack. This would mean that the site could be secure again from a secondary attack within hours.
