La série de portes SPM disposent d’une aile coulissante et sont équipées d’un type de mouvement pneumatique/oléo-dynamique. Pour assurer l’étanchéité anti-radiation sur le périmètre externe, les ailes chevauchent, pour le passage de l’ouverture, la longueur supérieure jusqu’à au moins dix fois la distance existante entre la barrière blindée et le mur fixe.
La porte coulisse à l’intérieur du canal intégré dans le sol, afin de créer 100 mm de chevauchement blindé même sur la partie inférieure. La porte tire la planche mobile, avec des composants en acier inoxydable, qui garantit la continuité du sol à n’importe quelle condition.
Les portes SPM sont actionnées par un vérin pneumatique à double effet, qui assure un mouvement souple, linéaire et extrêmement silencieux. Le circuit oléohydraulique spécial et le vérin pneumatique ont deux fonctions importantes :
Régulation de la vitesse d’ouverture et de fermeture
Réalisation des rampes d’accélération et de décélération à proximité de la position d’arrêt.
Les portes SPM sont équipées d’un couvercle, constitué de panneaux ennoblis en aluminium bordés de blanc qui ont pour fonction de fermer le canal au sol du côté de l’ouverture de la porte.
