    • 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.
    • 在电梯装置中,制动控制装置具有第一至第三制动控制部。 当检测到异常时,第一制动控制部分启动起重机制动器,并使垂直移动的主体进入紧急停止。 当起重制动器的紧急停止被激活时,第二制动控制装置减小升降机制动器的制动力,当垂直移动体的减速度等于或大于预定值时。 第三制动控制部,当启动起重机制动器的紧急停止时,监视主绳索相对于驱动绳轮的滑动速度,当主绳索的滑动速度等于或大于预定值时,第三制动控制部 制动控制部分减小起重机制动器的制动力。
