Abstract (en)
[origin: EP1780160A1] A control device stores, in correspondence with the position of a car, an overspeed setting level that is set to become smaller in the vicinity of a terminal end portion of a hoistway toward the terminal end portion. When the detected speed of the car exceeds the overspeed setting level at the position of the car as detected by an encoder, an activation signal is outputted from the control device. Emergency braking is applied on the car as a brake device or a safety device is activated upon the input of the activation signal. The control device is electrically connected with a display that displays the position of the car obtained based on information from the encoder, and the value of the overspeed setting level at that position of the car.
