Abstract (en)
[origin: EP2186768A1] In an elevator apparatus, a safety gear makes a car perform an emergency stop in response to an activating signal. A slippage monitoring apparatus computes a slippage extent value that is a value that relates to extent of slippage of a suspending body relative to a driving sheave based on the signals from first and second speed detectors. The slippage monitoring apparatus stops the car at a predetermined floor using a hoisting machine if the slippage extent value exceeds a first threshold value, and activates the safety gear using the activating signal if the slippage extent value exceeds a second threshold value.
