    Aper\u00e7u du produit<\/h1>\n<\/li>\n<\/ol>\n

    Le r\u00e9ducteur de pivotement (\u00e9galement appel\u00e9 bo\u00eete de vitesses de pivotement, r\u00e9ducteur de pivotement ou entra\u00eenement de pivotement) est un composant de transmission essentiel du syst\u00e8me de pivotement des pelles sur chenilles.<\/p>\n

    Il transf\u00e8re et convertit le couple du moteur d'orientation en une sortie \u00e0 vitesse r\u00e9duite et \u00e0 couple \u00e9lev\u00e9 pour faire tourner la structure sup\u00e9rieure de l'excavateur en douceur et de mani\u00e8re fiable.<\/p>\n

    Num\u00e9ros de pi\u00e8ces :<\/h2>\n

    31NB-11150\/31NB-11151<\/p>\n

    Ces mod\u00e8les sont des pi\u00e8ces d'origine ou de remplacement con\u00e7ues pour les excavateurs Hyundai R450LC-7 et Hyundai R500LC-7.<\/p>\n

    Selon la configuration de l'\u00e9quipement, les deux mod\u00e8les peuvent \u00eatre interchangeables ou jumel\u00e9s de mani\u00e8re fonctionnelle au sein du m\u00eame syst\u00e8me d'entra\u00eenement de la balan\u00e7oire.<\/p>\n
