Articulated suspension system for crane girders with positive-locking load transfer

Abstract

Articulated suspension system for a crane girder or a dynamically loaded steel structure, comprising a support plate (1) and a forming bolt (2) inserted into a recess (4) of the support plate (1), wherein the suspension system is designed for connection with an upper flange (5) of the crane girder, such that in the state mounted on the crane girder a lower flange (6) of the crane girder is kept free as a track for a trolley or carriage, characterized in that the recess (4) of the support plate (1) has a curved inner contour and the forming bolt (2) has a corresponding curved outer contour, wherein the forming bolt (2) has an upper contact area for force transmission and lateral contact surfaces,so that, in the assembled state, the interaction of the corresponding contours enables a positive-locking and articulated load transfer between the support plate (1) and the form bolt (2), as well as a load transfer to the upper flange (5).
