摘要：
A car is suspended by suspension means and raised and lowered by a hoisting machine. Electric power supplied to a motor of the hoisting machine is controlled by an electric power converter. The electric power converter is controlled by a control apparatus. The control apparatus estimates a maximum value of a regenerative voltage at time of a regenerative operation of the hoisting machine when the car is running. When the estimated maximum value of the regenerative voltage reaches a predetermined voltage limit value, the control apparatus controls the electric power converter so as to stop an increase in estimated maximum value of the regenerative voltage.
