\"CICSA<\/strong><\/p>\n

Les cha\u00eenes CICSA grade 8 sont fabriqu\u00e9es conform\u00e9ment aux normes internationales en vigueur ISO 3076-3056-4778-7593, selon les normes europ\u00e9ennes EN 818-1\/2\/4 et DIN 5687-5688.<\/p>\n

Les mat\u00e9riaux utilis\u00e9s pour les cha\u00eenes grade 8 sont des aciers alli\u00e9s de haute qualit\u00e9 qui d\u00e9passent les exigences minimales de performance des normes.<\/p>\n

Les cha\u00eenes et accessoires de levage CICSA grade 8 permettent d\u2019obtenir:<\/p>\n

    \n
  • plus de l\u00e9g\u00e8ret\u00e9 par rapport aux cha\u00eenes en acier courantes gr\u00e2ce \u00e0 leurs propri\u00e9t\u00e9s m\u00e9caniques \u00e9lev\u00e9es qui permettent de r\u00e9duire leur diam\u00e8tre;<\/li>\n
  • une excellente r\u00e9sistance aux charges dynamiques (haute r\u00e9silience) et aux sollicitations \u00e0 la fatigue;<\/li>\n
  • une dur\u00e9e de vie prolong\u00e9e gr\u00e2ce \u00e0 d’excellentes caract\u00e9ristiques anti-usure (duret\u00e9 moyenne: HRC 38);<\/li>\n
  • une temp\u00e9rature d\u2019utilisation de -40\u00b0C \u00e0 +200\u00b0C sans r\u00e9duction de la capacit\u00e9 de charge;<\/li>\n
  • une s\u00e9curit\u00e9 absolue et une assurance qualit\u00e9 totale gr\u00e2ce aux contr\u00f4les les plus stricts appliqu\u00e9s aux processus de fabrication et aux produits et technologies de pointe adopt\u00e9s.<\/li>\n<\/ul>\n

    Charge de travail maximale<\/h3>\n

    La charge de travail maximale est la charge maximale \u00e0 laquelle la cha\u00eene et les accessoires peuvent \u00eatre soumis pendant l’utilisation. Elle d\u00e9pend des r\u00e8gles de s\u00e9curit\u00e9 en vigueur dans les diff\u00e9rents pays. Au niveau international et selon les normes EN-ISO-DIN, le rapport entre la charge de rupture minimale garantie et la charge limite d’utilisation de la cha\u00eene de levage est de 4.<\/p>\n

    Charge d’essai de construction<\/h3>\n

    Cette charge est celle \u00e0 laquelle l’ensemble de la cha\u00eene est test\u00e9 et correspond \u00e0 60% de la charge de rupture minimale. Selon les normes EN, ISO et DIN, elle correspond \u00e0 environ 2,5 fois la charge de travail.<\/p>\n

    Charge de rupture minimale<\/h3>\n

    Il s’agit de la charge minimale que la cha\u00eene doit supporter lors de l’essai de traction effectu\u00e9 jusqu’\u00e0 la rupture. L’allongement minimum \u00e0 la rupture (pourcentage de d\u00e9formation permanente) est de 20%.<\/p>\n

    Test de pliage<\/h3>\n

    La cha\u00eene et les anneaux de levage sont soumis \u00e0 des essais de pliage conform\u00e9ment \u00e0 la norme EN 818-2.<\/p>\n

    Identification<\/h3>\n

    La cha\u00eene grade 8 de CICSA est marqu\u00e9e sur le c\u00f4t\u00e9 non soud\u00e9 des maillons de la lettre \u00ab\u00a0C\u00a0\u00bb ou du nom complet \u00ab\u00a0CICSA\u00a0\u00bb (selon la dimension de la cha\u00eene) et du chiffre 8, indiquant respectivement le fabricant et la classe de r\u00e9sistance (EN, DIN, ISO 8).<\/p>\n

    En outre, une plaque octogonale est appos\u00e9e sur chaque \u00e9lingue reportant:<\/p>\n

      \n
    • la marque CICSA;<\/li>\n
    • le nombre de brins (1 pour les tron\u00e7ons simples) de l\u2019\u00e9lingue;<\/li>\n
    • le diam\u00e8tre de la cha\u00eene en mm;<\/li>\n
    • la charge maximale d’utilisation exprim\u00e9e en \u00ab\u00a0t\u00a0\u00bb, \u00e9ventuellement en fonction de l’angle de travail (\u00e9lingue \u00e0 plusieurs brins);<\/li>\n
    • le code de tra\u00e7abilit\u00e9;<\/li>\n
    • le marquage \u00ab\u00a0CE\u00a0\u00bb prescrit (conform\u00e9ment \u00e0 la Directive Machines).<\/li>\n<\/ul>\n
