Abstract

L'invention concerne un dispositif pour l'arrêt de la rotation relative de deux éléments coaxiaux. Elle est caractérisée en ce qu'il comporte un moyen de butée, associé au moins à l'un desdits éléments et tournant librement, coaxial par rapport à ceux-ci, pourvu d'une aile latérale, un premier moyen de blocage, solidaire dudit premier élément, interférant avec l'aile dudit moyen de butée et un deuxième moyen de blocage solidaire du deuxième élément, interférant avec l'aile du moyen de butée. L'invention s'applique aux grues autoportées.The invention relates to a device for stopping the relative rotation of two coaxial elements. It is characterized in that it comprises a stop means, associated with at least one of said elements and rotating freely, coaxial with respect to them, provided with a lateral wing, a first locking means, integral with said first element, interfering with the wing of said stop means and a second locking means integral with the second element, interfering with the wing of the stop means. The invention applies to self-supporting cranes.
