Abstract

PURPOSE: To prevent the breakaway of a hanging rope from a circumferential groove of a grooed pulley by means of protective pins, etc. even when a cage is subject to a sudden impact and slack is formed to the hanging rope.
CONSTITUTION: A grooved pulley 2 is axially mouned to a central upper portion of a holding frame 1, which is installed to a cage and a weight in an elevator, by means of a supporting shaft 3, and a pair of circular arc covers 4, 5 are fixed to the inside of said holding frame 1 being close to a lower portion of an outer circumference of the grooved pulley 2 by means of mounting portion materials 6. Protective pins 7, 8 are each mounted to each upper end portion 4a, 5a of said each circular arc cover 4, 5. Said arrangement prevents the slack of a hanging rope 9 by means of each protective pin 7, 8 and each circular arc cover 4, 5 when an emergency stop motion functions and the weight springs up or when cage itself springs up by the reaction force and even when slack is formed to the hanging rope 9, and does not break away one portion of the handing rope 9 wound on a circumferential groove 2a of the grooved pulley 2 from the circumferential groove 2a.
