Title: Transfer bridge

Abstract: A transfer bridge for ramps. The bridge includes a bridge plate, the rear end of which is pivotable about a horizontal axis. The bridge plate is provided with a retractable and extendable extension which in turn is provided with tongues capable of being push-in. The extension is for placement upon the platform to be loaded or unloaded, and the tongues are automatically secured or arrested in the pushed-in condition. A drive, such as a piston, is associated with the tongues, or with the extension carrying the tongues, for retracting the tongues or the extension, subsequent to a pushing-in of the tongues, to form a gap between the tongues on the one hand and the platform (walls) on the other hand.
