Abstract

A loading bridge for ramps has a bridge plate having a forward and a rearward end and connected with the rearward end to the ramp so as to be pivotable about a horizontal axis. An extension is connected to the forward end of the bridge plate so as to be extendable from an initial position into an extended position for supporting the bridge plate on a platform 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 is provided for supporting the bridge plate in a rest position. The support leg is pivotably connected 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 at the upper end an end face for supporting a downwardly extending part of the bridge plate. The support leg has at the upper end a holding member extending upwardly toward the bridge plate for pivotably connecting the upper end to the bridge plate.

A loading bridge for ramps, said loading bridge comprising:

a bridge plate having a forward and a rearward end and connected with said rearward end to the ramp so as to be pivotable about a horizontal axis;
said bridge plate comprising a downwardly extending cross beam connected at said forward end;
an extension connected to said forward end of said bridge plate so as to be extendable from an initial position into an extended position for supporting said bridge plate on a platform to be loaded and unloaded and retractable from said extended position into said initial position;
at least one support leg with an upper and a lower end for supporting said bridge plate in a rest position;
said at least one support leg pivotably connected to said bridge plate such that said lower end swivels upwardly toward the rearward end of the bridge plate when said extension is extended;
said at least one support leg having at said upper end an upwardly facing end face, wherein said cross beam rests on said end face in said rest position;
and
at least one holding member with a first and a second end, fixedly connected with said first end laterally to said upper end of said at least one support leg and extending in said rest position upwardly from said end face toward said bridge plate past said cross beam, wherein said second end is pivotably connected to said bridge plate above said cross beam.
