Abstract

Le système de commande de synchronisation des mouvements de deux éléments, par exemple une griffe (3) et un organe de manutention (2) tel qu'une benne, comprend un système de synchronisation (6) des systèmes de commande (1, 4) qui modifie les positions des deux éléments (2, 3) concomitamment avec un circuit hydraulique en série. Les éléments ont des amplitudes de position différentes et le système comprend un système de poursuite de mouvement qui permet que, lorsque l’un des éléments arrive en une position de butée, l’autre élément continue son mouvement jusqu’à une position de butée.
