The inspection frequency should be determined by a particular installation or similar installations, severity of environment , percentage of capacity lifts, frequency rates of operation, and exposure to shock loads.
Periodic inspections with a signed report should be performed by an appointed or authorized person. This inspection should cover the entire lenth of rope. The indi-
vidual wire in the strands of the rope should be visible to this person during the inspection. Any deterioriation resulting in appreciable loss of original strength, such as described below, should be noted and determination made as to whether further use of the rope would constitute a hazard:
Distortion of the rope such as kinking, birdcaging, crushing, unstranding, main strand displacement, or core protrusion.
Reduction of rope diameter below normal diameter due to loss of core support, internal or external corrosion, wear of outside wires. Severely corroded or broken wires at end connetions. Severely corroded, cracked, bent, worn, or improperly applied end connections. Lubrication.
Special care should be taken when inspecting portions subjected to rapid deterioration such as the following:
Portions in contact with saddles, equalizer sheaves, or other sheaves where rope travel is limited.
Portions of the rope at or near terminal ends where corroded or broken wires may protrude.
No precise rules can be given for determination of the exact time for replacement of rope, since many variable factors are involved. Continued use in this respect depends largely upon good judgment by an appointed or
