Abstract

L'invention concerne un système de freinage pour engin de génie civile (11) comprenant des freins de manoeuvre (36, 37, 38, 39) actionnés par des soupapes de commande (41, 42, 46, 47) alimentées en liquide sous pression par une soupape de sécurité (57, 58) qui protège contre l'activation accidentelle des freins de manoeuvre (36, 37, 38, 39) en cas de défaillance ou de dysfonctionnement d'un organe du système de freinage.
