A vertical moving method of a vertical moving apparatus including a vertical moving unit on which a conveyance target object is mounted, the vertical moving apparatus further including: a support unit configured to vertically movably support the vertical moving unit; a non-electric biasing unit configured to generate a biasing force to raise the vertical moving unit; an electric motor unit configured to generate a thrust for a vertical movement of the support unit; and a first electromagnetic brake unit configured to apply a braking force to the vertical movement of the support unit, the method comprising steps of: causing the non-electric biasing unit to generate a biasing force to raise the vertical moving unit; causing the 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 the first electromagnetic brake unit to generate a braking force to resist a movement of the vertical moving unit, characterized in that: independently of presence/absence of the conveyance target object and a weight of the conveyance target object placed on the vertical moving unit, 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, the electric motor unit comprises an electric motor, and a second electromagnetic brake different from the first electromagnetic brake unit, and when the vertical moving unit stops due to action of the external force, the electric motor is stopped, and rotation of an output shaft of the electric motor is braked by the second electromagnetic brake. a support unit configured to vertically movably support the vertical moving unit;
