Abstract

Appareil de levage hydraulique comportant au moins un bras articulé, actionné par un vérin, et des moyens pour détecter la pression du circuit d'alimentation du vérin hydraulique. Les moyens détecteurs de pression 2 sont agencés pour bloquer en 3 le bras dès que le moment de la charge engendre une pression supérieure à une valeur prédéterminée; en outre, sont prévus des moyens 6 de contrôle de sécurité du mouvement du bras agencés pour permettre, grâce à des moyens détecteurs 5 de la position angulaire du bras, la commande en 7 du bras uniquement selon une séquence qui diminue le moment de la charge. Application aux appareils auxiliaires de manutention.
