L’acc\u00e8s aux pyl\u00f4nes de pont pour l’entretien et la maintenance est l’un des d\u00e9fis les plus complexes rencontr\u00e9s par les entreprises d’ascenseurs et d’acc\u00e8s. Les solutions d’ascenseurs Alimak s’adaptent aux inclinaisons et aux courbes, aux espaces restreints et aux conditions venteuses pour atteindre le pinacle des structures les plus hautes.<\/p>\n\n\n\n
En 2002, un ascenseur Alimak SE 500 sp\u00e9cialement fabriqu\u00e9 pour le transport de personnes a \u00e9t\u00e9 mis en service pour permettre l’acc\u00e8s \u00e0 l’une des meilleures vues panoramiques de la capitale tha\u00eflandaise. L’ascenseur est install\u00e9 \u00e0 l’int\u00e9rieur du pyl\u00f4ne en b\u00e9ton en Y invers\u00e9 du prestigieux pont \u00e0 haubans Rama VIII, qui traverse la rivi\u00e8re Chao Phraya \u00e0 Bangkok. Mesurant 0,9 m x 1,3 m, il remonte le long d’un des pieds du pyl\u00f4ne \u00e0 une vitesse de 1 m\/sec. \u00c0 environ 75 m, la remont\u00e9e ralentit \u00e0 0,2 m\/sec pour s’adapter \u00e0 la mont\u00e9e verticale, puis reprend sa vitesse maximale pour le reste du trajet jusqu’\u00e0 la plate-forme d’observation au sommet du pyl\u00f4ne de 161 m de haut. Le rail de guidage de l’ascenseur U-600 est incurv\u00e9 \u00e0 une inclinaison de 13\u00b0 dans la partie inf\u00e9rieure et devient vertical dans la partie sup\u00e9rieure. Alimak y est parvenu en divisant la structure principale en cinq parties.<\/p>\n\n\n\n
Le pont Rama VIII porte le nom de l’ancien roi Rama VIII de Tha\u00eflande et a \u00e9t\u00e9 officiellement inaugur\u00e9 en septembre 2002, l’ann\u00e9e m\u00eame o\u00f9 Bangkok a c\u00e9l\u00e9br\u00e9 son 220e anniversaire. Il a une port\u00e9e principale de 300 m et poss\u00e8de deux voies de circulation \u00e0 double sens, ainsi qu’une voie pour les v\u00e9los et les pi\u00e9tons.<\/p>\n\n\n\n
Parmi les autres exemples de projets de ponts dans le monde o\u00f9 des ascenseurs industriels ou des ascenseurs de chantier Alimak ont \u00e9t\u00e9 install\u00e9s, on peut citer :<\/p>\n\n\n\n
