Abstract

L'invention concerne un appareil à commande multiple pour soutènement marchant hydraulique. L'appareil de l'invention comprend un bloc distributeur central 1 auquel sont adaptés des éléments de commande fermés 2 raccordés l'un à côté de l'autre et indépendamment l'un de l'autre sur les côtés longitudinaux opposés du bloc distributeur 1. Dans ces éléments adaptés 2, se trouvent des soupapes de précommande 3 actionnées au moyen de boutons-poussoirs 403 à 418, sollicitées par une pression de commande réduite et actionnant les soupapes d'alimentation de pression des cylindres de travail. L'appareil de l'invention est utilisé pour faciliter la tâche d'un opérateur d'un soutènement marchant, tout en permettant des réparations plus aisées.
