Empty container storage for the intermediate storage of empty ISO containers
An empty container store for the temporary storage of empty ISO containers, in particular in fully automatic container terminals of sea ports or river ports includes a gantry bridge crane which spans the empty container store. The gantry bridge can be moved on an elevated craneway and has a traveling crab which can be moved thereon in the longitudinal direction thereof. A vertical lifting column is fastened to the traveling crab for lifting and lowering a load receiving means for the empty container. The load receiving means includes a spreader on a spreader support which is arranged on a spreader carriage which is guided on the lifting column by rollers on a spreader support.
1. An empty container store for the temporary storage of empty ISO containers in a fully automatic container terminal of ports, comprising:
an elevated craneway;
a gantry bridge movably supported on said craneway and spanning the empty container store; and
a traveling crab movably mounted on said gantry bridge for moving in a longitudinal direction of said gantry bridge, said traveling crab having a vertical lifting column and a load receiving means for receiving an empty container, said load receiving means being movable along said vertical lifting column,
wherein said load receiving means comprises a spreader carriage guided on said vertical lifting column via rollers, a spreader support mounted on said spreader carriage and a spreader supported by said spreader support, and
wherein said spreader support and said spreader are pivotable relative to said vertical lifting column from a first loading region proximate said lifting column to a second loading region remote from said lifting column, wherein said first and second loading regions are separate and non-overlapping.
2. The empty container store of claim 1 , wherein said vertical lifting column comprises a lattice mast structure having three chords, said load receiving means being vertically movably guided on said lattice mast structure.
3. The empty container store of claim 2 , further comprising a double cable lifting mechanism having deflection rollers arranged on said vertical lifting column for vertically moving said spreader carriage.
4. The empty container store of claim 1 , wherein said traveling crab is movable to an end position proximate a rail of said craneway, wherein said spreader extends through posts of said craneway when said traveling crab is in the end position and said spreader is pivoted to said second position.
5. The empty container store of claim 1 , further comprising a bearing framework arranged proximate said craneway for supporting at least a first row of empty containers in a region of the empty container store proximate said craneway, said bearing framework comprising vertical columns having a height corresponding to the height of the maximum number of stacked containers and a horizontal clearance allowing transverse through-passage of the empty containers and being smaller than a length of the shortest container to be stacked.
6. The empty container store of claim 1 , further comprising a double cable lifting mechanism having deflection rollers arranged on said vertical lifting column for vertically moving said spreader carriage.
7. The empty container store of claim 1 , wherein load receiving means further comprises parallel links connecting said spreader support to said spreader carriage and a piston-cylinder unit for pivoting said spreader support between said first and second positions.
8. The empty container store of claim 7 , wherein said traveling crab is movable to an end position proximate a rail of said craneway, wherein said spreader extends through posts of said craneway when said traveling crab is in the end position and said spreader is pivoted to said second position.
9. The empty container store of claim 1 , wherein said first loading region in within the empty container store and the second loading region is outside of the empty container store.
10. An empty container store for the temporary storage of empty ISO containers in a fully automatic container terminal of ports, comprising:
an elevated craneway;
a gantry bridge movably supported on said craneway and spanning the empty container store; and
a traveling crab movably mounted on said gantry bridge for moving in a longitudinal direction of said gantry bridge, said traveling crab having a vertical lifting column and a load receiving means for receiving an empty container, said load receiving means being movable along said vertical lifting column,
wherein said load receiving means comprises a spreader carriage guided on said vertical lifting column via rollers, a spreader support mounted on said spreader carriage and a spreader supported by said spreader support, wherein said spreader support and said spreader are pivotable from a first position proximate said lifting column to a second position remote from said lifting column, and wherein load receiving means further comprises parallel links connecting said spreader support to said spreader carriage and a piston-cylinder unit for pivoting said spreader support between said first and second positions.
11. The empty container store of claim 10 , wherein said traveling crab is movable to an end position proximate a rail of said craneway, wherein said spreader extends through posts of said craneway when said traveling crab is in the end position and said spreader is pivoted to said second position.
