Although a certain amount of wear is seen due to the sliding contact with 1A, 31B, the sliding of the braking shoes 31A, 31B against the peripheral wall 19 is immediately before the car 3 is sufficiently decelerated and stopped. Therefore, as compared with the contact between the sheave 26 and the main rope 5, the amount of wear is small. Therefore, the peripheral wall 1 of the rotary frame 16 that becomes the rotary drum of the brake 29
The replacement time of the rope 9 is longer than the replacement time of the sheave 26 once every 5 to 10 years.
