<P>PROBLEM TO BE SOLVED: To provide a hoisting rope for an elevator having a long service life and high fatigue resistance and stabilized in shape in terms of year by increasing the density of core steels and diffusing a force for fastening steel strands brought in contact with core steel strands when a load is applied. <P>SOLUTION: A rope 1 is wound around a driving sheave 2 connected to a driving motor, and an elevator cage 3 for a passenger is hoisted at one end thereof, and a balance weight 4 is hoisted in the other end. This rope 1 is constituted of a core steel 11 formed of central fiber bundles and steel strands 12 arranged at the periphery of the core steel and formed by twisting steel wires 121. The core steel 11 formed of the fiber bundles is constituted of one core strand 113 manufactured by twisting fiber bundles and arranged as a core body in a central part of the core steel and four core steel strands 112 arranged at the periphery of the core strand to form the periphery of the core steel. <P>COPYRIGHT: (C)2010,JPO&INPIT |
