Avon EB950CR Armstrong PAS68 High Security Barriers provides a high level of protection where central roadway foundations are not possible / practical. 

Avon Armstrong High Security PAS 68 Barriers are designed to complement Avon Barriers range of high security PAS68 road blockers, EB950CR Crash Tested PAS 68 Barriers can withstand direct impact forces in excess of 720 KJ crash tested to PAS 68, High Security Barriers provides shallow mounted protection to sites from extreme Vehicle Borne Improvised Explosive Device (VBIED) attack.

High Security Barriers PAS 68 Impact Test

PAS 68 High Security Barriers were developed by our in-house engineering team using the Company's significant historical expertise in rising arm barrier solutions coupled with the experience of impact resistance theory, EB950CR PAS 68 High Security Barriers are highly dependable security products that will easily interface with a wide range of control equipment. The PAS68 crash tested barriers are assembled in our fabrication facilities using heavy gauge materials to give maximum strength and durability. This makes our PAS68 security barriers traditional looking control barriers with the benefits of high level physical protection.

EB950CR high security barriers have been independently physically crash tested in a number of full scale crash tests conducted in accordance with PAS 68 by the Transport Research Laboratory (TRL).PAS 68 Crash Tested Barriers by Avon Barrier

The EB950CR PAS68 security barrier is an Electro-Hydraulically operated rising arm barrier with arm widths of up to 4.5m span. The barriers arm sits 1 m above the roadway and is supported by 2 side support frames. During impact the arm slides into a locked position protecting the main drive mechanism from damage. Raised/Lowered back indication signalling can be provided to enable remote monitoring of the high security barriers status on a real time basis (optional).

The hydraulic power pack is controlled by a programmable controller enabling connection of virtually any access control to the rising arm barrier. In the event of power failure a manual pump is provided to ensure operator control is maintained.

Avon EB950CR PAS68 crash tested barriers 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 as options) and any configuration including (but not limited to) inductive loop systems, card readers and communication equipment can be accommodated.High Security PAS 68 Crash Tested Barriers

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

  • Full PAS 68 Classification: V/7500(N2)/48/90:0/0 Tested Model 1mHx3mW
  • Operating temperature range available -25 deg C - +70 deg C
  • Barriers construction: The boom catcher frames are fabricated from heavy steel sections, which are anchored into the foundations: they are designed to support the boom in the lowered position and to take a full impact load.
  • The recess in the catchers prevents the boom from lifting when impacted. Outboard extensions inhibit the vehicle running up the catcher frame.
  • The boom is fabricated from heavy steel section clamped to a lift yoke which is designed to slip through its clamp in the event of a collision, to engage under the catcher frame recesses.
  • The lift assembly comprises twin cranks welded to a solid shaft, which rotates in non-metallic bearings. A heavy-duty steel yoke is welded to the outer ends of the shaft.
  • The crank is rotated through 90 degrees by the action of a hydraulic cylinder.
  • Main barriers cabinet is constructed from steel plate; it houses the hydraulic equipment/reservoir, drive mechanism and electrical enclosure.

Options Available

  • Emergency buttons with lock down
  • UPS backup for the electrical system
  • Accumulator systems for hydraulic operation in power fail conditions
  • Access control and intercom systems
  • Inductive loop systems
  • Traffic lights and back-indication system
  • Interlocking systems to give air-lock type protection on sites for higher threat levels
  • Integral inset warning lights
