    Abstract: The invention relates to a method for providing condition data of an elevator rope. The method comprises: using current state condition data representing a condition of the elevator rope for the length of the elevator rope in a current state and condition change data indicating at least one potential change in the condition of the elevator rope as input data of a rope condition model; processing the input data with the rope condition model to provide output data comprising condition data of the elevator rope in a new state; and utilizing the provided condition data of the elevator rope to update the current state condition data or in an elevator call allocation process. The invention relates also to an elevator computing system and a computer program product for providing condition data of an elevator rope.

    Abstract: An elevator includes an elevator car and a counterweight; a first roping between the elevator car and counterweight and including at least one rope; a second roping between the elevator car and counterweight and including at least one rope; and a rope wheel arrangement, having at least one rope wheel, around which the at least one rope of the second roping passes. The longitudinal force transmission capability of the at least one rope of the second roping is based essentially on non-metallic fibers and is a belt-like rope having at least one contoured side provided with guide rib(s) and/or guide groove(s) oriented in the longitudinal direction of the rope, the side being fitted to pass against a contoured circumference of a rope wheel of the rope wheel arrangement, the circumference being provided with guide rib(s) and/or guide groove(s) so as to form a counterpart for the contoured side of the rope.

    Abstract: A tension member tension monitoring arrangement and method for measuring tension member tension of elevator tension members of a bundle of tension members, the elevator comprising an elevator car suspended by the tension members, such as ropes or belts, of the bundle of tension members, a termination at one end of a tension member and a mounting plate for attaching the termination relative to the hoistway, counterweight and/or the elevator. The tension member tension monitoring arrangement comprises at least one capacitive pressure sensor arranged in connection with a tension member termination. The arrangement further comprises a control unit connected to the at least one sensor. The at least one sensor is configured to sense the tension member forces of the tension members of the bundle of tension members attached to the tension member termination and generate a signal relating to one or more tension members of the tension member bundle readable and/or measurable by the control unit and proportional to the sensed load or force.
