Abstract

L'invention concerne une grue équipée d'une flèche à faculté de décalage angulaire variable, ainsi qu'un dispositif pour relier la flèche à l'appendice de flèche de ladite grue. Ledit dispositif comprend une première biellette 76 pouvant pivoter sur un tenon supérieur 62 ; une seconde biellette 72 pouvant pivoter sur l'appendice 54 d'une flèche 12, chacune desdites biellettes 72, 76 étant percée d'un trou 72b, 76a à son extrémité opposée à sa liaison respective, au moins l'une 72 de ces biellettes présentant un trou 72c à mi-chemin de sa longueur ; ainsi qu'un tourillon 78 traversant de manière libérable les trous précités 72b ou 72c et 76a pour permettre un pivotement dudit appendice 54 et son décalage angulaire d'un angle prédéterminé par rapport à ladite tête 52.
