In an elevator apparatus, a car is raised and lowered by a plurality of hoisting machines. Braking apparatuses are disposed on the respective hoisting machines. The braking apparatuses are controlled individually by respective brake controlling means. The respective brake controlling means detect states of rotation of the respective hoisting machines during emergency braking, and control braking forces from the respective braking apparatuses in response to the detected states of rotation. |
