摘 要：
In an elevator apparatus, a pulley is
provided in a hoistway. A rope that moves together with the movement of a car is wound around the pulley. Further, the pulley is provided with a pulley sensor for generating a signal according to the
rotation of the pulley. The car is provided with a car speed sensor for directly
detecting the speed of the car. A control panel is provided with: a first speed
detecting portion for obtaining the speed of the car based on information from the pulley sensor; a second car speed
detecting portion for obtaining the speed of the car based on information from the car speed sensor; and a determination portion for determining the
presence/absence of slippage between the rope and the pulley by comparing the speeds of the car as respectively
obtained by the first and second speed detecting portions.
