Patent ID: 8818550

Claim:
A horizontal circuit storage system ( 1 ) for storing storage goods carried by load-carriers ( 6 ), said system having a storage zone ( 2 ) with at least three stacked horizontal storage planes ( 5 ), and a plurality of load-carriers ( 6 ) each arranged in a row on said stacked horizontal storage planes, the storage zone ( 2 ) being defined between two vertical conveyors ( 3 , 4 ) movable between the storage planes ( 5 ) in a vertical direction, a horizontal conveyor ( 8 ) associated with each storage plane ( 5 ) for moving the load-carriers ( 6 ) in the storage planes ( 5 ) in the direction of the vertical conveyors ( 3 , 4 ), wherein a control unit ( 18 ) is provided, said control unit adapted to control the horizontal circuit storage system ( 1 ) so that two of the at least three storage planes ( 5 a , 5 b ; 5 c , 5 d ) and both of the vertical conveyors ( 3 , 4 ) are each driven in pairs in opposite directions to form a horizontal circuit ( 65 ) for the load-carriers ( 6 ) across the two storage planes ( 5 a , 5 b ; 5 c , 5 d ) and the vertical conveyors ( 3 , 4 ).
