Abstract

A storage facility (1) having a plurality of storage racks (R) and storage rack levels (3) for storage of load units (T), wherein two storage racks (R) have an aisle (2) between them, each storage rack level having running rails on the opposing faces of the storage racks (R), on which at least one storage and retrieval apparatus (5) may travel the length of the aisle (2). Each storage and retrieval apparatus (5) has a first set of four traveling wheels for traveling along the running rails horizontally along the respective storage rack level (3) of an aisle (2), and has climbing means for vertical movement, along vertical climbing chimneys. The climbing means of each storage and retrieval apparatus (5) include a set of four climbing wheels (16) being retractable between an extended engaging position for interaction with the vertical climbing rails and a retracted non-engaging position while travelling horizontally along the running rails along the respective storage rack level (3) and the storage and retrieval apparatus (5) has power-take-up device (60) for contacting the bus bars (50) that are coupled to the retraction and extension movement of the climbing wheels (16).
