Abstract (en)
In an elevator apparatus, a brake control device controls a brake device for braking a travel of a car and performs a rescue operation when the car is stopped between floors. During the rescue operation, the car is moved to a landing floor by using imbalance between a load of the car side and a load of a counterweight. The brake control device includes a first computing section and a second computing section for executing the same computation processing independently of each other for performing the rescue operation. The first computing section and the second computing section compare their own computation results with each other to detect a failure of at least one of the first computing section and the second computing section.
