1. A lift carrier device that lifts or lowers and carries an article, the lift carrier device comprising:
a first article stage which includes a first conveyor capable of moving the article in a longitudinal direction; a first longitudinal drive device which supports and drives the first article stage in a longitudinally movable manner; a first lift drive device which supports and drives the first longitudinal drive device in a liftable manner: a second article stage which includes a second conveyor capable of moving the article in the longitudinal direction; a second longitudinal drive device which sandwiches the first article stage with the first longitudinal drive device in a lateral direction perpendicular or substantially perpendicular to the longitudinal direction, and supports and drives the second article stage in a longitudinally movable manner on a first longitudinal drive device side; a second lift drive device which supports and drives the second longitudinal drive device in a liftable manner; and a controller configured or programmed to cause the first longitudinal drive device and the second longitudinal drive device to be relatively lifted or lowered by the first lift drive device and the second lift drive device, to cause the first article stage and the second article stage to pass by each other in a state where the first article stage and the second article stage have been moved by the first longitudinal drive device and the second longitudinal drive device to positions where the first article stage and the second article stage do not longitudinally overlap each other in plan view. |
