发明名称 Transloading bridge for ramps
摘要 A transloading bridge for ramps with a bridge plate, the rear end of which is adapted to be pivotally connected to a ramp and the front end of which is provided with an extension adapted to be moved from a retracted position into a moved-out position for resting on a platform to be loaded or unloaded. The extension is also adapted to be moved from its moved-out position into its retracted position. The extension which is located below the bridge plate has longitudinal slots extending in the longitudinal direction of the bridge, while webs serving as reinforcements for the bridge plate extend through the slots and are connected to the bottom side of the bridge plate. Those longitudinal bridge sections of the extension which are separated from each other by the longitudinal slots are reinforced by longitudinally extending additional webs, preferably of U-shape, and are connected to the extension.
