The following criteria will determine when an equalizing cable is no longer
acceptable for service:
12 randomly distributed broken wires in one lay or four broken wires in one strand in one lay
in running ropes
one outer wire broken at the contact point with the core of the rope, which has worked its
way out of the rope structure and protrudes or loops out from the rope structure
wear of one-third the original diameter of outside individual wires
kinking, crushing, birdcaging, or any other damage resulting in distortion of the rope structure
evidence of heat damage from any cause
reduction from nominal diameter greater than those listed in the following table:
Note:
Attention shall be given to end
connections. Upon development of two
broken wires adjacent to socket end
connections, the rope shall be resocketed
or replaced. Resocketing shall not be
attempted if the resulting rope length will
be insufficient for proper operation.
