Yellow Stripe - Vehicle barricades

The Avon RB780CR Chieftain High Security Road Blocker Barricade is a crash tested anti-terrorist hydraulic wedge style vehicle barricade providing a high level of security against unauthorised vehicle access....


The PAS68 High Security Barricade is designed to withstand direct impact forces in excess of 1,852 KJ, and still remain operational in readiness of further attack, the road blocker barricades provide protection to sites from extreme Vehicle Borne Improvised Explosive Device (VBIED) attack.

The security road blocker is designed and manufactured by engineers with significant experience in the fields of high security and access control, RB780CR high security road blocker barricades are highly dependable security vehicle blocking systems with a PLC logic control enabling easy interface with a wide range of control equipment.

High Security Anti Terrorist Road Blocker Barricades

The PAS68 road blockers are assembled in our fabrication facilities using heavy gauge materials to give maximum strength and durability. This makes anti-terrorist RB780CR Security Road blocker Barricades ideal barrier systems to protect high security establishments, iconic buildings and critical infrastructure.

RB780CR Road Blocker Barricades have been independently structurally evaluated by the Transport Research Laboratory (TRL) and has also been physically tested in a number of full scale crash tests conducted in accordance with PAS 68 by the Motor Industry Research Association (MIRA).  This led to the RB780CR Chieftain High Security Road blocker Barricade becoming one of the first British built road blockers installed by the British Government.  These tests are internationally recognised as equivalent to the US DOS K12 crash test and ASTM F 2656-07.

PAS 68 Crash Test of Anti Terrorist Road Blocker Barricades

RB780CR High Security Road blocker barricades are Electro Hydraulically operated wedge blocking systems with segment widths available from 2m to 5m (in 500mm increments). The blocker barricade has an 800mm height when fully raised and is comprised of a static sub-surface ground frame with hinged, rising impact wedge. Raised/Lowered back indication signalling can be provided to enable remote monitoring of the blocker status on a real time basis (optional).

The hydraulic power pack is controlled by a programmable logic controller (PLC), enabling connection of virtually any access control to the road blocker. In addition, the PLC can be configured to enable the blocker to be raised quickly (in less than 1 second) in an emergency by utilising an hydraulic accumulator (optional). In the event of power failure a manual pump is provided to ensure operator control is maintained.PAS 68 Anti Terrorist Road Blocker Barricades Production

PAS68 (equiv. K12, ASTM F 2656) road blocker barricade comes with a push-button control as standard. However, it can be customised to interface with a wide range of access control equipment to suit specific customer requirements. Available configurations include (but are not limited to) inductive loop systems, card readers, communication equipment and manned guard emergency systems.

Where the Security Road blocker control point is remote from the installation, we strongly recommend the fitting of a recordable CCTV system, traffic lights and safety inductive loop systems. For safety reasons pedestrians, cyclists and motorcycles are advised not to use a blocker controlled roadway. Additional safety measures can be incorporated into the blocker system if required.
