摘要

A method for braking a traction sheave elevator stops the elevator in the event of an emergency by the braking of the elevator using a braking device not comprised in the drive machine. A traction sheave elevator is provided with a braking device not comprised in the drive machine and designed to improve the efficiency of emergency stopping. The maximum force decelerating the elevator and generated by the braking device equals about half the weight of the nominal load of the elevator.
