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.
Claims10
A transfer bridge for use between a ramp and a platform traversible by a vehicle, said bridge comprising:
- a bridge plate having a first end and a second end, said first end being pivotably connected to said ramp in such a way as to be pivotable about a horizontal axis;
- a retractable and extendable extension provided in said second end of said bridge plate for placement on said platform;
- arresting means actuatable in response to a pushing-in movement of said extension held thereby in a pushed-in position;
- tongues supported by and extending from said extension, and capable of being respectively pushed-in, i.e., of being pushed toward said first end of said bridge plate, said tongues, in the pushed-in state, being automatically arrested in position by said arresting means;
- and
- drive means associated with one of said extension and said tongues for retracting same, subsequent to a pushing-in of said tongues, to form a gap between said pushed-in tongues and said platform rather than moving said tongues against a vehicle.
