Avon RB780CR Chieftain Road Blocker

RB780CR Chieftain Road Blocker Hostile Vehicle Mitigation (HVM) Solution PAS 68 impact tested

The Avon RB780CR Chieftain Road Blocker is designated as a Hostile Vehicle Mitigation (HVM) Solution having been PAS 68 impact tested.

Withstanding direct impact forces in excess of 1,852 KJ, the RB780CR road blocker provides protection to sites from extreme Vehicle Borne Improvised Explosive Device (VBIED) attack.

It has been independently, structurally evaluated by the Transport Research Laboratory (TRL) and has also been physically tested in a number of full scale impact tests conducted in accordance with PAS 68 by the Motor Industry Research Association (MIRA).

Product overview

The RB780CR Chieftain Road Blocker achieved a PAS 68 classification of V/7500(N2)/80/90:0/17, which interprets as a 7500kg (N2) vehicle travelling at 80 kph (50mph) impacting the road blocker at a 90 degree angle and stopping the vehicle without penetrating past the blocking system.

The road blocker comes with a push-button raise or lower control as standard.

The road blocker 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.

Developed and manufactured by engineers with significant experience in the fields of high security and access control.  The Chieftain Road Blocker is an ideal product to protect high security establishments, iconic buildings and critical infrastructure.

This is a specialist high security product and is designed for use with vehicles only and a full site risk assessment must be carried out at design stage to ensure that all relevant safety systems are included. Where the blockers control point is remote from the installation, we strongly recommend the fitting of a recordable CCTV system. For safety reasons pedestrians, cyclists and motorcycles should not to use a blocker controlled roadway.
