ABSTRACT:
A transfer bridge for bridging across railroad tracks. The transfer bridge includes a bridge plate that can be pivoted from a vertical rest position into a horizontal operative position, in which the free end of the bridge plate rests upon a platform next to the tracks. In addition, a travel mechanism that is movable parallel to the tracks is associated with the bridge. In order to achieve a simplified and smaller construction for the travel mechanism, the latter is provided with an upwardly extending boom that is held in a guide rail to keep it from tilting.
