Abstract

L'invention concerne un procédé et un appareil servant à commander un instrument (14) de travail relié de façon mobile à un engin (10) de terrassement. Un dispositif de commande (28) d'instrument commande automatiquement des premier et second modes de commande simultanés de fonctionnement, lesdits modes étant assignés à l'instrument (14) de travail. Un capteur (42) envoie un signal au dispositif de commande (28) d'instrument pour indiquer la position de l'instrument (14) de travail. Le dispositif de commande (28) d'instrument inverse les premier et second modes simultanés de commande assignés à l'instrument (14) de travail après détection d'un mouvement de travail prédéterminé. En outre, le dispositif de commande (28) d'instrument déplace automatiquement l'instrument (14) de travail d'une première position rotative à une seconde position rotative symétrique à la première, suite à la manoeuvre effectuée par un opérateur d'un dispositif (49) à actionnement manuel. On peut également modifier les assignations des premier et second modes simultanés de commande en actionnant le dispositif (49) à actionnement manuel.
