What size vehicle can it stop; what level of impact can it withstand?
The LW4 is crash-rated by SCEC to absorb a minimum of 300 kJ of impact energy – which equates to a standard 1.3 tonne passenger vehicle travelling at 80 kilometres per hour, or an 8-tonne truck traveling at 30 kph. It will arrest a vehicle within 1 metre, when mounted on a suitable anchor. Therefore it will also stop a much larger vehicle travelling at a lower speed – the relationship between the vehicle mass and the speed of impact being a simple mathematical formula. LW-3 is SCEC-rated to withstand 260 kJ – impact at 72 kph, and LW6 is designed to withstand 600 kJ. Is it rated and approved for Security use? Yes. FOLDING BLOCK technology LW4 and LW3 are rated by ASIO-T4 Protective Security Group for the Security Construction and Equipment Committee (SCEC) for use at Australian Federal Government sites. What makes it work so effectively? 3 years of research & development has engineered a combination of complex metallurgy with a FOLDING BLOCK design and an advanced GROUND ANCHOR technol
