INSPECTION METHOD FOR BRAKING DEVICE OF ELEVATOR, METHOD OF CAUSING TRANSITION TO OPERATING STATE OF ELEVATOR APPARATUS, AND DEVICE FOR PERFORMING TRANSITION TO OPERATING STATE

摘要

PROBLEM TO BE SOLVED: To design an inspection method enabling efficient, reliable inspection of a braking device of an elevator.;SOLUTION: The braking device 11 for the elevator performs braking and holding of an elevator car 2. The braking device 11 for the elevator is constructed by a plurality of braking units 12 engaged with a braking track 6 when required. For this purpose, the braking unit 12 presses at least one braking plate 14 to the braking track 6 to generate braking force. According to the invention, in order to inspect the braking device 11, an effective coefficient μe of friction of the braking unit generated is made clear when the braking plate 14 is pressed to the braking track 6. Further, when this inspection method is used, the transition to the operating state is described, and the device for performing the transition to the operating state is presented.;COPYRIGHT: (C)2008,JPO&INPIT
