An raising/lowering conveyance apparatus according to the present invention is provided with at least two sets of container holding means (20A, 20B), and the container holding means (20A, 20B) are configured so as to be raised/lowered in conjunction with each other, and to be freely movable closer to or away from containers (C) in the back-and-forth horizontal direction. A sensor (47) that detects the upper end height of the transferred containers (C) which have been transferred and raised is attached to a position near the lower end of each container holding means (20A, 20B), and determines abnormality in posture of the transferred containers (C) through a comparison operation between the value of the upper end height of the transferred containers detected by the sensor (47) and the normal value of the upper end height of the transferred containers calculated on the basis of the height of the container (C) being handled. |
