Abstract

See full text

The loading bridge for ramps has a bridge plate having a forward and a rearward end. It is connected with the rearward end to the ramp so as to be pivotable about a horizontal axis. An extension connected to the forward end of the bridge plate is provided and is extendable from an initial position into an extended position for supporting the bridge plate on a vehicle to be loaded and unloaded and retractable from the extended position into the initial position. At least one support leg with an upper and a lower end for supporting the bridge plate in a rest position is provided. The support leg is pivotably connected with the upper end to the bridge plate such that the lower end swivels upwardly toward the rearward end of the bridge plate when the extension is extended. The support leg has a positioning lever. The extension has a downwardly projecting beam. Upon extending the extension the positioning lever is loaded by the downwardly projecting beam such that the positioning lever is pivoted together with the support leg into a folded position. In the folded position the positioning lever rests on the downwardly projecting beam. The downwardly projecting beam has such a length that the support leg is secured against returning into the rest position over the entire travel length of the extension from the initial position into the extended position.
