The Avon RB880CR Defender Shallow Road Blocker provides a high level of protection where deeper foundations are not possible / practical. With a shallow foundation the RB880CR Defender crash tested security road blocker is designed to complement the Avon Barrier range of Hostile Vehicle Mitigation (HVM) solutions. The RB880CR road blocker can withstand direct impact forces of 1,852 KJ, providing shallow mounted protection to sites from extreme Vehicle Borne Improvised Explosive Device (VBIED) attack.
The high security road blockers were developed by our in-house engineering team to overcome specific site limitations and using the experience gained with the design, testing and production of the RB780CR Road Blockers, RB880CR is an additional highly dependable security product that will easily interface with a wide range of control equipment.
Units are assembled in our fabrication facilities using heavy gauge materials to give maximum strength and durability. This makes the RB880CR an ideal product to protect high security establishments, iconic buildings and critical infrastructure where existing underground services or other depth restrictions are an issue.
The RB880CR Road Blocker has been independently physically tested in a number of full scale crash tests conducted in accordance with PAS 68 by the Transport Research Laboratory (TRL). This led to the RB880CR Defender High Security Road Blocker becoming the first British built shallow foundation road blockers installed by the British Government.
The RB880CR is an electro-hydraulically operated blocking system with a standard segment width of 2m or 3m. The blocker has an imposing 1m height when fully raised and is comprised of a static sub-surface ground frame with foundation support legs and a 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 blocker. In addition, the PLC can be configured to enable the road blocker to be raised quickly (under 1 second) in an emergency by utilising a hydraulic accumulator (optional). In the event of power failure a manual pump is provided to ensure operator control is maintained. The blocker can also be fitted with an optional debris protection skirt.
