A ramp member for a loading dock has a bridge member with a forward and and rearward end. The rearward end is connected to the loading dock so as to be pivotable about a horizontal axis. An extension plate is connected with a first end by a pivot connection to the forward end of the bridge member such that the extension plate is pivotable from a folded position into a working position. In the rest position of the bridge member the extension plate is folded and rests on an abutment for supporting the bridge member. The first end of the extension plate has a projection extending over its entire length. The projection has a cross-sectional shape of a circular ring sector with an inner and an outer radius. The outer surface of the projection is defined by the outer radius and the inner surface is defined by the inner radius. A profiled member with an interior space is connected to the forward end of the bridge member and extends over the entire length of the pivot connection. The projection extends into the interior space of the profiled member. The profiled member has a bead on which the projection is pivotably supported with its inner surface. The bead defines the pivot axis of the pivot connection. The inner radius of the projection and the exterior radius of the bead are identical.
