Abstract

Appareil de levage hydraulique comportant deux bras articulés, actionnés par des vérins, et des moyens pour détecter la pression du circuit d'alimentation des vérins hydrauliques.
Les moyens détecteurs de pression 21, 23, sont agencés pour bloquer en 27a, 35a les bras dès que le moment de la charge engendre une pression supérieure à une valeur prédéterminée; en outre, sont prévus des moyens 31 à 34, 37 à 40, 45 à 48 de contrôle de sécurité des mouvements des bras agencés pour permettre, grâce à des moyens détecteurs 30, 36 des positions angulaires des bras, la commande en 27b, 35b des bras uniquement selon une séquence qui diminue le moment de la charge.
Application aux appareils auxiliaires de manutention.
