    Abstract: 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.

    Abstract: An elevator includes hoisting ropes and a compensating device. The hoisting ropes include first rope portions under a first rope tension that go upward from an elevator car and second rope portions under a different, second rope tension that go downward from the elevator car. The compensating device acts in substantially opposite directions on the first and second rope portions in order to do one or more of the following: equalize the first, second, or first and second rope tensions; compensate the rope tensions between the first and second rope tensions; equalize rope elongation in the first, second, or first and second rope portions; compensate the rope elongations between the first and second rope portions; and render a ratio of the first rope tension to the second rope tension substantially constant. The compensating device produces an auxiliary force acting substantially in a same direction as the first rope tension.
