ABSTRACT:
A transfer bridge for ramps, docks, or other platforms. The retractable and extensible extension of the bridge plate is mounted on guide elements. Provided at the edges of the bridge are longitudinally extending racks that mesh with two pinions that are rigidly interconnected. In order to assure a rattle-free guidance, support wheels are associated with the pinions for relieving the latter of radial load. These support wheels roll on a planar track.
