Avon RB780CR Chieftain High Security Road Blockers are anti terrorist roadblockers that provide a high level of security against unauthorised vehicle access.


PAS68 High Security Road Blockers are designed to withstand direct impact forces in excess of 1,852 KJ. The road blockers provide protection to sites from extreme Vehicle Borne Improvised Explosive Device (VBIED) attack. View our PAS 68 Crash Testing Program.

PAS 68   Crash Tested Road Blockers - RB780CR

The anti-terrorist security road blockers are designed and manufactured by engineers with significant experience in the fields of High Security and Access Control, the RB780CR high security road blocker is a highly dependable security product that will easily interface with a wide range of control equipment.


The PAS68 road blockers are assembled in our fabrication facilities using heavy gauge materials to give maximum strength and durability. This makes the RB780CR security roadblocker the ideal product to protect high security establishments, iconic buildings and critical infrastructure.PAS 68 Road  Blockers Crash Test Sequence - RB780CR Road Blockers

The RB780CR Road Blocker has 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 Roadblocker becoming one of the first British built roadblockers installed by the British Government.

RB780CR High Security Roadblockers are electro-hydraulically operated blocking systems with segment widths available from 2m to 6m (in 500mm increments). The blocker 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 signaling can be provided to enable remote real time status monitoring (optional).Security Road Blockers - PAS 68 RB780CR

The hydraulic power pack is controlled by a programmable logic controller (PLC), enabling connection of virtually any access control to the roadblocker. In addition, the PLC can be configured with an hydraulic accumulator to enable the blocker to be raised quickly (in less than 1 second) in an emergency (optional). A manual pump is provided to ensure that operator control is maintained in the event of power failure.

Road Blockers High Security crash tested to PAS 68The PAS68 roadblockers come 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.
