PERIMETER ANTI-RAM SYSTEM

摘要

Disclosed herein are passive and active vehicle arresting barrier systems that may be combined to provide anti-ram protection along an entire perimeter of a secured area including vehicle access points. A perimeter fence portion (30) is a passive barrier system (40) that stops an attacking vehicle (90) within a predetermined penetration distance and may blend into an existing perimeter fence structure to provide an architecturally hidden structure. The access opening portion utilizes a collapsible road deck and an underlying pit that does not require hydraulic or electrical means to deploy.
