SMA proposed to the client different types of impact Crash cushions by positioning the devices in front of the obstacle to be protected and supplying them.
Impact Crash cushions were installed in tunnel niches, bypasses, and in front of toll stations.
Thanks to our engineering consulting service, we have provided ad hoc solutions in accordance with the configuration of the obstacle to be protected.
Crash cushions had to have specific characteristics:
- Be fireproof: plastic, in fact, in tunnels is highly discouraged - or just not allowed by law, as happens in Italy - because it is flammable; SMA produces devices that are completely made of steel, which do not increase the risk of fire, as well as being much more resistant to temperature changes;
- Have the smallest possible footprint: an attenuator that was too long would have prevented vehicles from using the bypass for any emergency stops. When it comes to a gallery, the less space the shock Crash cushions take up, the better. However, you can not give up safety performance, to the point that it is inadequate, especially on an underwater road with very high traffic of people and goods. The Leonidas SMA Crash cushions are special in the way they combine Maximum Performance with Minimum Footprint;
- Be easily repairable: in the event of an accident against the attenuator, it is necessary to restore the device in the shortest possible time. SMA Leonidas is repairable in just 30 minutes;
- Respect a certain aesthetic criterion (the Crash cushions had to be orange): SMA devices are all made of Hot Galvanized Steel, but on request, it is possible to carry out a powder coating in the desired color.
This engineering and industrial work together was done taking into serious consideration the delivery time of the project.
SMA boasts a 99.2% accuracy on delivery times, and, especially in a monumental work like this, respecting the agreements became essential.
