PROBLEM TO BE SOLVED: To suppress a peak current while suppressing an increase of a cycle time of operation in a lifting device.SOLUTION: A lifting device for conveying a load in the vertical direction includes: a holding base for holding the load and vertically moving; a lifting motor for driving the holding base in the vertical direction; and a control means for controlling the lifting motor. The control means includes a rise control part for controlling the lifting motor so that a rising deceleration time ud1 which is a time from a normal speed of the holding base until the holding base is stopped is shorter than a rising acceleration time ua1 which is a time from a rising start of the holding base until the holding base reaches the normal speed. |
