    Patent number: 11465883
    Abstract: An elevator arrangement, comprising at least one rope connected with an elevator car; a rope wheel arrangement comprising at least one rope wheel around which the rope passes turning around an axis, which extends in width direction of the rope; and a rope position detector arranged to detect displacement of the rope over at least one limit position and to trigger one or more predetermined actions in response to detecting displacement of the rope over a limit position. The rope is arranged to pass around a rope wheel turning around an axis, which extends in width direction of the rope, and the rope position detector is arranged to detect displacement of the rope over a limit position in thickness direction of the rope at a detection point, and to trigger one or more predetermined actions in response to detecting displacement of the rope in its thickness direction over the limit position, said limit position being on the opposite side of the rope than said rope wheel.
