Figure 44A.
An
outer strand (top) from a 19 x 7 rotation resistant rope shows nicking that
occurs between adjacent strands as well as between strands and the inner rope (bottom).
Similar nicking patterns occur
in
other ropes with
an
IWRC.
Figure
44B.
An
outer strand removed from a wire rope that experienced strand-to-strand nicking. This nicking results from adjacent
strands rubbing against one another and can be an indication
of
core failure, operation
of
the rope under high loads, improper sheave
groove contour or small bending radii. Ultimately, this may result
in wire breaks
in
the valleys between the strands.
