And a load transfer means 7 composed of Reference numeral 8 denotes a shelf, which is erected on one side of the crane traveling route 3 along the crane traveling route 3.

The shelf 8 is provided with a large number of load receiving portions 9 which are three-dimensionally partitioned in the vertical direction of the traveling direction of the crane. A comb-teeth-shaped load receiving base 11 that forms the load transfer base elevating space 10 (three in the illustrated example) is installed.
Each of the load transfer table elevating spaces 10 formed by the comb-shaped load receiving table 11 has a length that extends over substantially the entire depth of the load receiving portion 9, and the crane traveling path 3 side thereof is open.

The load transfer table 6 of the crane 1 is driven up and down by the lift carriage 5, and is also movable horizontally toward and away from the lift carriage 5 toward the side where the shelf 8 is located. The traverse table 12 is a comb tooth-shaped one composed of a traverse table 12 and a plurality of (three in the illustrated example) load supporting members 13. The traverse table 12 is laid on the up-and-down carriage 5 in the lateral direction. Is movably supported on the guide rails 14 of the above, and the load supporting members 13 are cantileveredly projected from the lateral moving table 12 to the side where the shelves 8 are arranged in parallel with each other at appropriate intervals in the crane traveling route direction. ing. The elevating drive means of the elevating carriage 5 and the egress / retreat driving means of the load transfer table 6 (transverse table 12) are the elevating drive means of the elevating carriage and the load transfer table (running fork) in a conventional general crane of this type. Since it may be the same as the exit / retraction driving means of (1), illustration and description of its specific structure are omitted.

At the bottom of the shelf 8, a carry-out conveyor 15 is arranged. The carry-out conveyor 15 uses a belt conveyor including a conveyor belt 17 stretched in parallel with the crane traveling path 3 by a belt supporting roller 16. A partition member 18 is erected between the carry-out conveyor 15 and the crane traveling path 3 in parallel with the crane traveling path 3. The partition member 18
Is a strip-shaped plate that is continuous in the direction of the crane traveling path, is attached to the crane traveling path 3 side of the shelf 8 above the unloading conveyor 15, and is located at a position corresponding to each load receiving portion 9 in the direction of the crane traveling path.
