A method of manufacturing an elevator includes installing a movable supporting platform and an elevator car in the elevator hoistway; taking the elevator car into use to serve passengers and/or to transport goods; removing the elevator car from use; changing the service range of the elevator car to reach higher up in the elevator hoistway by lifting the supporting platform higher up in the elevator hoistway; and taking the elevator car back into use. The elevator is reeved to include construction-time hoisting roping, which includes one or more ropes, the longitudinal power transmission capacity of which is based at least essentially on non-metallic fibers in the longitudinal direction of the rope. In the method, guide rails to be fixed with guide rail brackets can additionally be installed by the aid of an installation device. An elevator arrangement can be used to perform the method.

The invention relates to a method for manufacturing a hoisting rope, comprising the steps of providing a plurality of elongated composite members, which composite members are made of composite material comprising reinforcing fibers in polymer matrix; and arranging the composite members to form an elongated row of parallel composite members, which row has a longitudingal direction, a thickness direction and a width direction, and in which row the composite members are positioned side by side such that they are parallel to each other, and spaced apart from each other in width direction of the row; and directing plasma treatment on the outer surface of the composite members; and embedding the composite members in fluid polymer material; and solidifying the polymer material wherein the composite members are embedded. The invention relates also to a hoisting rope obtained with the method and an elevator comprising the hoisting rope.

Disclosed is a non-steel strength membered high strength cable easily monitored for heat and elongation comprising a length of a core-cable (10), the length of core-cable (10) including at least two fiber-optic conductors (2) that are: (i) disposed in a helical shape; and (ii) completely encased in a solid, flexible material.
One fiber-optic conductor capable of transmitting at least Raman backscattering and the other fiber-optic conductor capable of transmitting at least Brillouin scattering. A combination of the cable (10): (i) with an interrogator that can read and interpret Raman backscattering coupled to and communicating with the fiber optic conductor that is capable of transmitting at least Raman backscattering; and (ii) another interrogator that can read and interpret Brillouin scattering coupled to and communicating with the fiber optic conductor that is capable of transmitting at least Brillouin scattering;
permits ascertaining the elongation of the cable, without using loose tube fiber-opticplacement.
