Abstract

Bras de soulèvement de charge avec maintien automatique de la charge en position donnée par rapport à l'horizontale. Le bras en porte-à-faux est muni d'un dispositif 11 de maintien à niveau fonctionnellement connecté entre l'accessoire 9 porteur de charge, le bras, et la surface de support, et pouvant agir pour maintenir automatiquement l'accessoire 9 en posture prédéterminée pendant les mouvements simultanés ou séparés de télescopage, de soulèvement, et/ou d'abaissement du bras. Applicable notamment aux grues, organes de levage de conteneurs, plateformes d'inspection, etc.Load lifting arm with automatic maintenance of the load in a given position relative to the horizontal. The cantilever arm is provided with a leveling device 11 operatively connected between the load bearing accessory 9, the arm, and the support surface, and capable of acting to automatically hold the accessory 9 in position. predetermined posture during simultaneous or separate arm telescoping, lifting, and / or lowering movements. Applicable in particular to cranes, lifting devices for containers, inspection platforms, etc.
