ELEVATOR ROPE SLIP DETECTOR AND ELEVATOR SYSTEM |
摘要 |
An elevator system in which a pulley is provided in an elevator shaft. A rope is entrained about the pulley to move as a cage moves. The pulley is provided with a pulley sensor generating a signal depending on rotation of the pulley. A rope sensor for measuring the moving speed of the rope is provided in the elevator shaft. A control panel has a first speed detecting section for determining the cage speed based on information received from the pulley sensor, a second speed detecting section for determining the cage speed based on information received from the rope sensor, and a judging section for judging whether a slip is present between the rope and the pulley according to the cage speed information determined, respectively, at the first and second speed detecting sections.
