Title:
ELEVATOR MALFUNCTION REMOTE RECOVERY SYSTEM AND ELEVATOR MALFUNCTION RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/134905
Kind Code:
A1
Abstract:
An elevator control device (200) transmits a malfunction signal to a remote recovery device (300) upon detecting the occurrence of self-locking in which engagement between a movable hook (563) of a movable engagement member (559A) and a fixed hook (564) of a fixed engagement member (559B) is not released although the movable hook (563) is biased in the opening direction by a vane (537) serving as a biasing member. Upon reception of the malfunction signal, the information processing device (360) of the remote recovery device (300) causes the elevator control device (200) to perform self-locking release processing operation for causing a car door motor (545) to repeat opening and closing movement so that the vane (537) intermittently strikes the roller (562) of the movable engagement member (559A) in the opening direction. In this way, the self-locking can be released.
