Abstract (en)
Provided is an elevator device with high convenience including two or more electromagnetic brakes, which prevents a passenger(s) from being trapped in a car as much as possible. The elevator device includes: a plurality of electromagnetic brakes; a plurality of brake switches for individually detecting an open state and a closed state; a door-opening zone detector; and a control section for outputting and interrupting brake release commands to perform opening and closing control for the plurality of electromagnetic brakes and for outputting a door-opening command and a door-closing command based on results of detection of the door-opening zone detector to perform opening and closing control for a door, in which, in a case where a state in which a closed state of at least one of the plurality of brake switches cannot be detected occurs even though brake close commands are output after landing, when it is detected that at least a predetermined number of the plurality of brake switches is in the closed state, the control device outputs the door-closing command after outputting the door-opening command for a predetermined time and then stops service of the elevator.
