Apparatus for conveying loads

摘要

An apparatus for conveying loads, in particular unit loads, with an overhead travelling crane (1) is provided with at least one bridge girder (2, 3) on which one or more main crabs (8) run on crane girder tracks (6) transversely to the displacement direction of the overhead travelling crane. On the bridge girder or girders (2, 3), one or more bottom tracks (11) are arranged below the crane girder tracks (6) for the main crabs (8). The bottom tracks (11) are likewise arranged transversely to the displacement direction of the overhead travelling crane. One or more storage crabs (13) run on the bottom track or tracks (11). The main crabs (8) and the storage crabs (13) are arranged relative to one another in such a way that unit loads (19) can be transferred from the main crabs (8) to the storage crabs (13) and vice versa. <IMAGE>
