ABSTRACT:
A height-adjustable docking buffer is described for protecting facades when vehicles are docked in building openings. The docking buffer is made up of a fixed mounting frame and a height-adjustable buffer block for a loading ramp or a transfer bridge. The buffer block is designed as an essentially horizontal bumper bar, and includes an inflatable gasket, the ends of which are height-adjustably supported on two spaced, fixed mounting frames, preferably in the form of pillars. A method for operating the docking bar is also disclosed.
