Abstract

PURPOSE: Stop operation of the elevator is distinguished to safely protect the passengers, by dividing the operation of the limit switch into two depending upon when the sheave is descended by the elongation of the main rope of the elevator and when the sheave is fallen as a result of the cut off of auxiliary ropes or derailment of the sheave.
