PROBLEM TO BE SOLVED: To dispense with an actuator and sensor at a storage crane side by absorbing the impact on a mechanical stopper by an impact absorbing mechanism while surely picking out carriages one by one by the stopper. SOLUTION: A mechanical stopper opening cylinder 7 mounted on a receiving side lane, extends against a compression spring 6 and presses a lower link of a toggle link, whereby a mechanical stopper is opened and a storage lane is raised to convey the carriages. Simultaneously, a receiving side lane is started. A conveying speed of the receiving side lane is determined to be faster than a speed of the storage lane, and a speed of the carriage reaching the receiving side lane is increased, to increase an interval between the carriage and a following carriage by the difference in speed. When a first carriage reaches the mechanical stopper, it is collided with a raised stopper part 4a on a point of a stopper arm 4 raised by the compression spring 6, and stopped. On this occasion, the vibration caused by the collision of the carriage is absorbed by totally inclining the impact absorbing mechanism.
