ABSTRACT:
A terminal slowdown apparatus for an elevator comprises an acceleration detecting circuit which detects an acceleration in the normal speed pattern or an acceleration of the cage; a relative speed pattern generator which generates a relative speed pattern depending upon the output of the acceleration detecting circuit and the position of the cage and a comparator which is actuated when the normal speed pattern or the cage speed is higher than the relative speed pattern whereby the normal speed pattern is switched to the terminal slowdown speed pattern by the operation of the comparator.
