Abstract: A bridging mechanism, the bridge plate of which can be pivoted from a vertical rest position behind the tracks into a horizontal operating position in which the free end of the bridge plate rests upon a dock or platform. The pivot connection of the bridge plate is mounted on a vertical support structure of a travel mechanism that is disposed behind the tracks. To achieve a large span length of the bridging mechanism where low ceilings are present, the pivot connection of the bridge plate is mounted such that it can be raised and lowered on the support structure. When the bridge plate is swung up out of the working position and into the approximately vertical rest position, the pivot connection is lowered, and when the bridge plate is swung down from the approximately vertical rest position into the operating position, the pivot connection is lowered.

Abstract: A mobile inclined ramp having longitudinal members that are disposed at the sides and are connected by transverse members that have a U-shaped cross-sectional configuraiton, with the cross parts of the transverse members being directed downwardly. To increase the load-carrying capacity of the tranverse members and to increase the traction of the travel surface of the ramp, plates are disposed between the cross parts of the transverse members. At the top, these plates end approximately at the level of anti-slip or traction elements of flanges of the transverse members. The plates are securely clamped between adjacent transverse members by bolt connections.
