LW7 Hostile Vehicle Mitigation Barrier

The AVS-elli LW7 HVM barrier is is the largest barrier in the LW series. Designed to be installed on a permanent basis* in high duty cycle environments for very heavy loads, both traffic and impact. The LW7 is ideally suited to military, correctional and other high security applications.

Folding Block technology enables the force of impact to be largely absorbed by the barrier itself, rather than the foundation. This type of barrier represents the latest innovation in barrier technology. Designed to be unobtrusive and act as a traffic calming device, when deployed it offers a formidable barrier.

PAS 68 tested by UK Government, AVS-elli FOLDING BLOCK barriers have proven vehicle stopping capability and reliability.

Our barriers are installed across across the world for a range of government and commercial clients. Contact AVS-elli if you require further details.

A derivative of this barrier has also been impact tested in conjunction with the HESCO Bastion and Highway Care fencing system for rapid protection with zero fixings.

AVS-elli barriers have protected the Prime Minister of Australia, the Cabinet of Australian Government, the last two Presidents of the USA when visiting Australia as well as visiting English Princes.

The AVS-elli designs are clean sheet designs developed by us over many years to provide a flexible adaptive barrier for use where standard foundation type barriers are not appropriate, or local weather conditions mean that long periods of water inundation are unavoidable.
