In an elevator device, a brake control device has first to third brake control sections. The first brake control section activates a hoist brake when an abnormality is detected and brings a vertically moving body into an emergency stop. The second brake control device reduces braking force of the hoist brake when deceleration of the vertically moving body is equal to or greater than a predetermined value when an emergency stop of the hoist brake is activated. The third brake control section monitors slip speed of a main rope relative to a driving rope sheave when the emergency stop of the hoist brake is activated, and when the slip speed of the main rope is equal to or greater than a predetermined value, the third brake control section reduces braking force of the hoist brake.
