Abstract: A vertical moving method of a vertical moving unit on which a conveyance target object is mounted includes steps of causing a non-electric biasing unit to generate a biasing force to raise the vertical moving unit, causing an electric motor unit to generate a thrust in a direction to raise the vertical moving unit or a thrust in a direction to lower the vertical moving unit, and causing an electromagnetic brake unit to generate a braking force to resist a movement of the vertical moving unit. Independently of presence/absence of the object and a weight of the object, the thrust and/or the braking force is controlled such that the vertical moving unit stops when an external force of overload more than a predetermined value acts on the vertical moving unit during a vertical movement.
