To accurately control an elevator while keeping a principle that the elevator is controlled by detecting operation in a rotative winding body at the driving side.

In this elevating conveyor system wherein each ropy body 16 hangingly supporting an elevating body 4 capable of loading and unloading articles A is wound and delivered by a rotative winding body 17 being rotated and driven by an elevating drive means 15, while an elevating control means controls operations of the elevating drive means 15 on the basis of detection information of a working quantity detecting means detecting a working quantity in the rotative winding body 17, the elevating control means finds a variation in the elongation of the delivery part due to a variation in load of an elevation body 4 in time of winding and delivering the ropy body 16 from load information of the elevating body 4 in time of winding the ropy body 16 by the rotative winding body 17 and load information of the elevating body 4 at the time of delivering the wound part, whereby a lifting position of the elevating body 4 in time of operating the delivery of the ropy body 16 is compensated in this way.
