Abstract
L'invention concerne un ensemble de poutre d'arc-boutant et de cric. Cet ensemble comporte une poutre télescopique dont les extrémités supportent chacune un cric hydraulique. Un élément de maintien est fixé de façon amovible sur la poutre et entoure partiellement le cric. Les charges verticales et les moments sont distribués uniformément par les épaulements prévus sur le cric d'une part et sur l'élément de maintien d'autre part. L'invention s'applique notamment à des arcs-boutants de grues mobiles.
