摘要

In an elevator device, an elevator car and a counterbalance weight are suspended by a suspending body.  The suspending body is wrapped over a drive sheave of a hoist.  A drive sheave-side detecting means generates a signal corresponding to a rotation of the drive sheave.  A suspending body-side detecting means generates a signal corresponding to a movement of the elevator car or the suspending body.  A condition monitoring device performs condition monitoring by comparing the difference between a position signal, which is sent from the drive sheave-side detecting means and occurs from the start to the stop of the elevator car, and a position signal, which is sent from the suspending body-side detecting means, with a predetermined threshold profile.
