Abstract:
A container bridge, comprising:a gantry having an upper horizontal member; two traveling supports on the gantry, the traveling supports having tracks supported from the upper horizontal member of the gantry so as to be beneath the upper horizontal member; at least two trolleys suspended on the tracks of the traveling supports, the tracks of a first one of the trolleys and the tracks of a second one of the trolleys being at a smaller distance from one another than a length of a longest container to be transported; and a respective lifting mechanism arranged on each of the trolleys, each lifting mechanism including devices for longitudinally moving the trolley along the traveling supports, and for gripping and lifting a container, the trolleys each being arranged to travel on respective tracks of the traveling supports so that a center of gravity of each container is below the tracks and so that travel paths of the trolleys cross one another so that the trolleys pass one another when traveling along their respective travel paths without either trolley requiring rotation of a suspended container to permit passing, the tracks being arranged in each case on a different traveling support.
