Les treuils de construction et les ascenseurs industriels Alimak ont \u00e9t\u00e9 utilis\u00e9s lors de la construction et de l’entretien continu du c\u00e9l\u00e8bre pont Queensferry Crossing en \u00c9cosse. Le pont, qui a ouvert ses portes en mai 2017, est le plus long pont \u00e0 haubans \u00e0 trois tours au monde et mesure 2,7 km de long.<\/strong><\/p>\n\n\n\n

\u00c9L\u00c9VATEURS DE CHANTIER<\/strong>
Six treuils de chantier Alimak Scando 650 ont permis d’acc\u00e9der aux trois pyl\u00f4nes en b\u00e9ton du pont suspendu lors de sa construction. Chaque machine a \u00e9t\u00e9 sp\u00e9cialement modifi\u00e9e pour cr\u00e9er une entr\u00e9e lat\u00e9rale – permettant aux passagers de sortir de la cabine de levage du m\u00eame c\u00f4t\u00e9 que la tour de m\u00e2t – sur le coffrage en b\u00e9ton mobile.<\/p>\n\n\n\n

Deux treuils ont \u00e9t\u00e9 install\u00e9s sur chaque pyl\u00f4ne, un Scando 650 DOL desservant le niveau de la mer au niveau de la route, et un Scando 650 FC desservant le niveau de la route jusqu’au sommet du pyl\u00f4ne, qui mesurait plus de 200 m\u00e8tres de haut.<\/p>\n\n\n\n

Alimak a con\u00e7u et fourni des plates-formes d’installation d’attaches sur chaque palan, offrant un environnement de travail plus s\u00fbr pour l’installation des attaches. Une traverse roulante sur mesure a \u00e9galement \u00e9t\u00e9 con\u00e7ue pour assurer l’interface entre le treuil et le coffrage en b\u00e9ton mobile, en tenant compte de toutes les forces et charges structurelles li\u00e9es \u00e0 l’utilisation de cet \u00e9quipement dans des environnements extr\u00eames.<\/p>\n\n\n\n

ASCENSEURS INDUSTRIELS<\/strong>
Trois ascenseurs industriels Alimak SE 500 sont install\u00e9s dans les pyl\u00f4nes du pont, \u00e0 raison d’un ascenseur par pyl\u00f4ne et desservant chacun 17 paliers. Ceux-ci offrent un acc\u00e8s s\u00fbr pour l’entretien courant du c\u00e2ble de suspension du pont.<\/p>\n\n\n\n

Les ascenseurs devaient s’adapter \u00e0 des gaines con\u00e7ues \u00e0 l’origine pour un produit alternatif. Alimak a adapt\u00e9 le produit standard SE 500 pour s’assurer qu’il s’int\u00e9grerait dans le puits existant.<\/p>\n\n\n\n

D\u00c9FIS DU PROJET<\/strong>
Rejoignant le projet \u00e0 un stade relativement tardif, Alimak devait travailler rapidement pour fournir un produit adapt\u00e9 dans un d\u00e9lai acceptable. En plus d’adapter les cabines d’ascenseur pour qu’elles s’int\u00e8grent dans la gaine, les ing\u00e9nieurs d’Alimak ont con\u00e7u des portes de cabine sp\u00e9ciales et incorpor\u00e9 des portes pali\u00e8res sur mesure en raison de certains paliers ayant des ouvertures limit\u00e9es.<\/p>\n\n\n\n

En raison du calendrier serr\u00e9, l’installation a commenc\u00e9 avant que les cabines d’ascenseur ne soient livr\u00e9es. Pour progresser, une plate-forme de montage a \u00e9t\u00e9 con\u00e7ue et int\u00e9gr\u00e9e afin que le m\u00e2t et les tirants puissent \u00eatre install\u00e9s.<\/p>\n\n\n\n

L’acc\u00e8s au puits \u00e9tait limit\u00e9, l’ascenseur devant \u00eatre install\u00e9 via une trappe de toit l\u00e9g\u00e8rement plus grande que la voiture r\u00e9elle. Cela signifiait que la cabine d’ascenseur devait \u00eatre retir\u00e9e de son cadre arri\u00e8re avant de l’abaisser en place.<\/p>\n\n\n\n
