Abstract

Il est décrit une méthode pour réaliser des essais de fonctionnement de systèmes de frein de stationnement d’une machine souterraine. La machine souterraine comprend un système de frein de service fonctionnant à l’aide de liquide pour frein et un système de transmission fonctionnant à l’aide de liquide de transmission. La méthode comprend la réception, par un contrôleur, d’une demande d’établissement d’un premier seuil de pression pour le liquide pour frein et un deuxième seuil de pression pour le liquide de transmission. La méthode comprend également l’actionnement, par le contrôleur, d’un frein de stationnement du système de frein de stationnement dans au moins un des cas suivants : la pression du liquide pour frein est inférieure au premier seuil de pression ou la pression du liquide de transmission est inférieure au deuxième seuil de pression.
