ABSTRACT:
An auxiliary device for operating a disabled elevator in case of emergency includes a pull cable and an action cable by which the disabled elevator can be raised or lowered to reach a desired floor. The pull cable is fastened at the top end thereof with one end of an application rod which is fastened pivotally at another end thereof in a control room located at the top of an elevator shaft. As the pull cable is pulled, an action rod is exerted on by the pressure of the application rod to disable the braking device so as to permit the elevator cab to be raised or lowered by a transmission box when the action cable is actuated.
