Abstract
Dispositif pour grues de chargement Il est caractérisé par le fait que lorsque la flèche est complètement repliée et que l'axe de pivotement entre le vérin principal et la flèche, est positionné rigoureusement sur une ligne imaginaire ou intérieurement par rapport à une ligne imaginaire s'étendant entre l'axe de pivotement précité et le point d'appui du vérin principal sur la colonne de grue, ledit dispositif, par application dans le vérin principal d'une pression destinée à relever la flèche ou avant l'application cette pression, déplace le point d'appui entre le verin principal et la flèche en éloignement par rapport à la colonne, sur une distance assurant le positionnement de ce point d'appui, sur le côté opposé de ladite ligne imaginaire d'inter-raccordement. L'invention trouve des applications pour le levage et la manutention.
