    caractérisé en ce qu'il est prévu un dispositif de freinage électrique (40) comportant un électroaimant de levage (41) et un bloc de freinage (44) rotatif et pouvant être déplacé axialement, qui comporte au moins un segment de freinage (45, 46), dans lequel l'électroaimant de levage (41) exerce une pression axialement dans la direction du cône de freinage (19), à l'état de freinage alimenté en courant du bloc de freinage (44) par l'intermédiaire d'un poussoir d'actionnement (42) en s'opposant à la force d'un ressort de rappel (43) et bloque un mouvement de rotation de l'arbre moteur (17) dans la direction de fermeture, et dans lequel le ressort de rappel (43) écarte axialement par rapport au cône de freinage (19) le bloc de freinage (44) à l'état non alimenté en courant de l'électroaimant de levage (41) de manière à ce que l'au moins un segment de freinage (45, 46) s'écarte du cône de freinage (19) et libère le mouvement de rotation de l'arbre moteur (17) dans la direction de fermeture.
  7. Dispositif de blocage selon la revendication 6,
    caractérisé en ce que le bloc de freinage (44) peut être mis en rotation par l'intermédiaire d'un évidement arrondi (44.1) sur une surface de guidage arrondie (24.1) de la partie de base (24) et est monté de manière à pouvoir se déplacer axialement, dans lequel le poussoir d'actionnement (42) agit sur une plaque d'actionnement (47) du bloc de freinage (44).
  8. Dispositif de blocage selon la revendication 6 ou 7,
    caractérisé en ce que le bloc de freinage (44) est réalisé de manière symétrique par rapport à l'axe vertical (z) et comporte deux segments de freinage (45, 46) qui sont disposés de manière opposée l'un à l'autre et agissent respectivement sur un segment angulaire du cône de freinage (19), qui est inférieur à 90°.
  9. Dispositif de blocage selon la revendication 8,
    caractérisé en ce que le bloc de freinage (44) et la pièce d'application de pression (30) sont disposés de manière à ce que les segments de freinage (35, 36) de la pièce d'application de pression (30) et les segments de freinage (45, 46) du bloc de freinage (44) alternent à la circonférence du cône de freinage (19).
  10. Dispositif de blocage selon l'une quelconque des revendications 6 à 9,
    caractérisé en ce que la sécurité de surcharge peut être déclenchée par une mise en rotation du bloc cde freinage (44) soumis à une charge en raison du fait que le bloc de freinage (44) agit sur la partie d'application de pression (30) et met cette dernière en rotation lorsqu'une valeur de seuil prédéterminée du couple de rotation est atteinte, dans lequel la partie d'application de pression (30) mise en rotation déclenche un micro-commutateur (48, 49) qui interrompt l'alimentation en courant de l'électroaimant (41) de manière à ce que le ressort de rappel (43) écarte axialement le bloc de freinage (44), à l'état non alimenté en courant de l'électroaimant (419, par rapport au cône de freinage (19), afin que l'au moins un segment de freinage (45, 46) du bloc de freinage (44) se sépare du cône de freinage (19) et libère le mouvement de rotation de l'arbre moteur (17) dans la direction de fermeture.
