• An elevator control device includes a control device main body that controls the operation of a force and monitors the presence or absence of an abnormality in the brake torque of a brake device that brakes the running of the car. If an abnormality in brake torque is detected when the force is stopped, it is determined whether the operation is controlled during a disaster. If the operation is controlled during a disaster, the door is allowed to open. Stop opening.

• the door opening operation is temporarily blocked (step S2), and whether the force of the cage 1 is stopped is monitored (step S3).
• step S4 it is checked whether there is an abnormality in the brake torque, that is, whether there is a torque drop. If the brake torque is normal, the car door and the landing door are opened (step S5), and the process is terminated. If an abnormality in the brake torque is detected, it is checked whether disaster control operation has been selected (step S6). If disaster control operation has been selected, the power door and landing door are opened (step S5), and the process is terminated.
