B. External Wear Patterns
Wear will normally extend along cable equal to the distance cable moves at that location. Wear may
occur on one side of the cable only or on its entire circumference. Replace flexible and non-flexible
cables when individual wires in each strand appear to blend together (outer wires worn 40-50
percent) as depicted in Figure 2.
C. Internal Cable Wear
As wear is taking place on the exterior surface of a cable, the same condition is taking place
internally, particularly in the sections of the cable which pass over pulleys and quadrants. This
condition, shown in Figure 3, is not easily detected unless the strands of the cable are separated.
Wear of this type is a result of the relative motion between inner wire surfaces. Under certain
conditions the rate of this type wear can be greater than that occurring on the surface.
