  • Patent number: 8235179
    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.
