Safety for road traffic

Inceasingly more road authorities require the use of forgiving masts and restricting the uses of slip bases.

Lattix® third generation forgiving masts, which are approved in conformity with NS-EN 12899, have no need for slip base.

When a vehicle crashes into a Lattix-mast, one of the corner elements is pressed inward and the mast bends. In addition the mast loosens all the way down from the footplate. The mast tips over the car and lands behind it. A Lattix® mast can be hit at any height, angle or speed. It doesn’t matter what kind of body the car has. A Lattix® mast always works!

Our vision - "The zero vision"

Lattix® complies with the Norwegian Public Roads
Administration's "zero vision", which has a clear goal: to work actively to reduce the number of people injured and killed in traffic accidents to the lowest possible number. "Zero" is the only acceptable number of people injured and killed. We should not lose anyone to meaningless traffic accidents, in Norway or in any other countries.

 

No reported fatalities

There are now thousands of Lattix® masts at roadsides. Cars have crashed into numerous masts but so far not a single fatality has been reported in these impacts.

 

Safety for aviation

 

As air traffic grows at an almost explosive force and as awareness in frangibility in all supporting structures alongside the airfield becomes a daily issue, the need for safer structures in all areas becomes evident. This includes everything from approach light masts to the ILS, AWOS, wind cone, antenna and perimeter surveillance supporting structures as well as FOD and Glidepath Towers. It is not only the air traffic that is growing, but all surrounding traffic as well. The infrastructure inside and outside the airfield is just as much affected - airport vehicles, people and goods.

Frangible supporting structures is the only way towards a safer, more reliable and sustainable airfield. With air traffic increasing, the need for safe and durable support structures also become more important. With an increased "frangibility" market, there is also a need for ICAO to continue to impose regulation governing a safer flight through frangible supporting structures.

Frangible structures need to withstand extreme weather conditions and exposion to jet blasts. In addition, the structure needs to collapse upon impact of a fragile aircraft wing. Strong, but frangible and safe.

Safety Compliance documentation

 

Lattix® has long experience in providing documentation on compliance to regulations. It has been in the frangible segment since the late 1980s, long before ICAO published its first frangible requirements.


With functional and safety requirements from both the traffic sector on passive safety, and the aviation sector on frangibility, the Lattix® products have been tested and certified since mid 1990s.
The testing is regularly supported by simulations.


The Lattix® masts have been crash tested to the European standard EN 12767 Passive safety of support structures for road equipment- Requirements and test methods, and to the ICAO Aerodrome Design Manual, part 6 Frangibility. The first full scale
ICAO compliance test was performed at Lista test center the summer of 1997, soon followed by EN 12767 testing for road safety.
In addition, regular strength testing in accordance with EN 12899-1 and documented quality controls ensure that the product maintain its quality and meet its specifications.


Lattix® has a long tradition of using third party documentation from independent test institutions and notified bodies.
