    La A32 Torino-Bardonecchia, detta anche \u201cL\u2019Autostrada del Frejus\u201d, rappresenta forse il principale collegamento stradale tra l\u2019Italia e la Francia, con grandi implicazioni non solo sulla societ\u00e0, ma anche sull\u2019economia (sia per quanto riguarda lo scambio di merci, che per quello che concerne il turismo). \nUn importante elemento di questa infrastruttura \u00e8 la galleria Prapontin, nella tratta Bussoleno \u2013 Susa Est. Questa galleria, lunga ben 4,4 km, venne ultimata nel 1994 come ultimo step prima della definitiva conclusione dei lavori che diedero vita all\u2019A32.<\/p>\n

    Nel 2012, questa essenziale via di comunicazione transfrontaliera \u00e8 stata interessata da lavori di ammodernamento e messa in sicurezza. SITAF, il gestore della A32, aveva, tra le altre cose, richiesto degli attenuatori d\u2019urto che fossero una vera protezione per tutte le migliaia di persone che ogni giorno circolano in quelle strade.<\/p>\n

    Si tratta di una delle prime forniture di attenuatori d\u2019urto effettuate dalla SMA Road Safety.<\/p>\n

    \n

    Problematica<\/h3>\n

    The positions in which these attenuators<\/a> were to be installed had two critical issues:
    \r\n1.The niches in the tunnel had sharp edges that were very dangerous for wandering vehicles;
    \r\n2.Next to the bypasses there were accesses to the service areas. Therefore, these passageways had to be maintained.
    \r\nIn addition, the niches where the attenuators were to be placed presented problems inherent in the available space, leading to problems for the construction of the foundation.
    \r\nThe alternative would have been the use of a lower class impact attenuator (from 80 to 50 km\/h) with the consequence that the level of containment guaranteed on the road section would not have been in accordance with the speed of travel of the road.
    \r\nAnother topic concerns the warranty offered by the components of the device according to the context in which it is used. The device, in fact, had to comply with the safety standards for road tunnels.<\/p>\n<\/div>\n

    \n

    Soluzione<\/h3>\n

    The great effort of analysis and engineering research carried out has allowed us to manage the supply project for the Frejus Motorway tunnel without serious hitches, respecting all the needs derived from the context, and to deliver the work by the pre-established date.
    \r\nSpecifically, the product proposed by SMA, had the following characteristics:<\/p>\n

      \n
    • compatto;<\/li>\n
    • integralmente in acciaio, dunque completamente ignifugo;<\/li>\n
    • alte prestazioni: da sempre, ed anche in questo caso, la tecnologia progettata da SMA unisce il minore ingombro ad una maggiore sicurezza, oltre che la possibilit\u00e0 di ripristinare l\u2019attenuatore in 30 minuti dopo un incidente.<\/li>\n<\/ul>\n

      The results obtained were really excellent, so much so that SITAF itself wanted to write to us to tell us how high the level of protection ensured by our attenuators was:
      \r\n\u201cWe are impressed by the more than satisfactory behavior of the restraint device and its \u201cmanual operation\u201d, with a complete \u201cpackaging\u201d of the elements such as to significantly reduce the effects of the accident on the driver of the vehicle involved, who got off the car with his own legs after a significant impact.\u201d<\/em><\/p>\n<\/div>\n

      Conclusioni<\/h3>\n

      \"\"<\/p>\n

      Security is for SMA the main purpose of all activity. The goal is to build solutions to save lives. And having such awards makes it even more clear how fundamental it is to continue to invest in research and in the creation of ad hoc projects that can respond to every type of need.
      \r\nA road without security is never viable. Thanks also to the role of SMA it becomes instead a trusted interconnection module for many citizens and companies, also capable of uniting several countries and cultures, as in the case of the A32, a connection to Europe without risk for those who travel it.<\/p>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
