<p><P>PROBLEM TO BE SOLVED: To provide a wire rope for running rigs having a proper friction coefficient. <P>SOLUTION: The wire rope for running rigs has an outer layer coated with a resin and the coating layer has a cross-sectional contour deviated from true circle on at least a part along the longitudinal direction of the wire rope. For example, a plurality of grooves or ridges extending in longitudinal direction are formed on the outer circumference of the coating layer interposing spaces in circumferential direction, a plurality of separated recesses or protrusions are formed on the outer circumference of the coating layer interposing spaces in the longitudinal or circumferential direction, or the cross-sectional form of the coating layer is formed in a polygonal form having≥5 sides. <P>COPYRIGHT: (C)2004,JPO</p> |
