A transferring shuttle for transferring a unit load between a pair of multi-tier racks in an automated storage/retrieval system in accordance with the present invention comprises a travelling platform adapted to travel between the multi-tier racks, respective telescopic mechanisms provided in the front and rear in such a form as to hold a unit-load carriage of the travelling platform therebetween, and respective outer fingers which are provided at both ends of a rail having the largest movable range in the telescopic mechanisms and movable between a projected position engageable with the unit load and a retracted position. The rail is also provided with an inner finger between the outer fingers. This structure allows the inner finger to push the unit load on the unit-load carriage of the transferring shuttle, whereby the unit load can be transported to a deeper part of the multi-tier racks than conventionally done. |
