Abstract

La présente invention concerne un procédé d'ouverture et de fermeture grâce auquel les ailettes d'un conteneur à ailettes peuvent être tournées à la main et autres même quand un certain type de dysfonctionnement se produit dans les unités d'actionnement de l'ouverture et de la fermeture (cylindres) et que les unités d'actionnement ne peuvent pas être utilisées, ainsi qu'un dispositif afférent. Une paire de tiges (9, 9) se trouve le long d'une poutre centrale (11) qui couvre la partie supérieure d'un conteneur (1). Quand les ailettes supérieures (2, 2), qui couvrent la moitié de l'ouverture supérieure du conteneur (1) et au moins la moitié supérieure de l'ouverture sur la surface de côté gauche ou droit sont montées sur lesdites tiges (9, 9) de manière à tourner librement, les ailettes supérieures (2, 2) sont tournées par des éléments (7) d'assistance à la rotation de travail qui sont obtenus à partir d'un élément à ressort, dont une extrémité se trouve sur l'ailette supérieure (2, 2) et dont l'autre extrémité se trouve sur le conteneur (1), conjointement avec des vérins hydrauliques (8) qui font tourner les ailettes supérieures (2,2).
