LW1.4 Hostile Vehicle Mitigation Barrier

The AVS-elli LW1.4 Hostile Vehicle Mitigation Barrier offers easy installation with its light weight and excellent stopping power.


The LW1.4 is a cost effective barrier for commercial applications in service stations (drive off protection), carparks, vehicle dealerships and other related applications. LW1.4 barriers can be specified as manually operated or electrically operated.

The LW1.4 surface mounted road blocker can be installed and deployed quickly on a suspended slab or bolted to a surface to provide temporary high security for access points.

The folding block barrier is designed to be installed on flat concrete slabs with the supplied shallow ramps to smooth vehicle transition. The 1.4 m wide blade allows the barrier to be put in the centre of a standard access lane to control vehicles accessing an area.

Successfully tested to the British PAS 68 certification to withstand a 1,500 kg vehicle travelling at 30 mph, this surface mounted product achieved zero vehicle penetration proving its incredible strength.
This barrier is effective and unobtrusive providing protection for narrow roadways, car parks and access doors. The LW1.4 is ideal for managing traffic flow and can act as a dampener when in the down position, effectively slowing vehicles down. Bolt down fixing allows rapid replacement after an incident or for ease of service.

Able to cope with a high number of operations each hour, the blocker is hydraulically operated and can be integrated into any existing control system .

Infrared beams and photocells are used to provide safety measures for the dynamic road blocker. Additional measures can be added to be site specific.
