Abstract

Un procédé permet de mettre hors circuit pendant la marche à vide un marteau perforateur et/ou un trépan à tranchement. Un embrayage (28) agencé au moins dans la chaîne cinématique de percussion est automatiquement désengagé lorsque le point mort est atteint. Le moment où l'outil (24) atteint une position située sur la course de marche à vide est détecté et l'embrayage (28) est automatiquement désengagé lorsque cette position est atteinte et enclenché à nouveau lorsque l'outil quitte cette position. A cet effet, un détecteur de marche à vide (30) provoque électromécaniquement l'engagement et le désengagement de l'embrayage (28) par l'intermédiaire d'un dispositif de commande (34). L'ouvrier maniant le marteau perforateur n'a donc pas besoin d'exercer d'efforts supplémentaires d'actionnement ou d'embrayage afin de mettre en et hors circuit l'outil à percussion, ce qui réduit le temps de marche à vide.
