A wire rope formed from a resin core and six strands, the resin core having an inner core with a circular cross section and an outer layer built up on the periphery thereof. The outer layer has a melting temperature lower than that of the inner core. The six strands are twisted together helically on the periphery of the resin core in an intertwining die in such a state that gaps are assured between the strands. The resulting wire rope is heated in a heating unit at a temperature higher than the melting temperature of the outer layer but lower than the melting temperature of the inner core. The wire rope is formed by subsequently compressing the six strands from the periphery thereof in a compressing die. The molten outer layer is hardened by natural cooling, after which the wire rope is taken up.

Running wire rope and method of manufacturing same

The present invention is to provide a hybrid core rope which does not require maintenance or a hybrid core rope capable of reducing a maintenance task. The hybrid core rope includes a resin solid core in which a plurality of spiral grooves is formed in the longitudinal direction on an outer peripheral surface thereof, a plurality of fiber bundles respectively spirally wound around the outer peripheral surface of the resin solid core along the plurality of spiral grooves, the fiber bundles having thickness to fill the spiral grooves, and a plurality of steel strands spirally wound around the outer peripheral surface of the resin solid core around which the fiber bundles are wound. The fiber bundles and the strands are respectively wound so as to have angles which are not parallel to each other.
