-
A. Wire rope attachments shall be replaced when cracked, deformed, or excessively worn.
B. At least once every 14 calendar days, each wire rope in service shall be visually examined along its entire active length for visible structural damage, corrosion, and improper lubrication or dressing. In addition, visual examination for wear and broken wires shall be made at stress points, including the area near attachments, where the rope rests on sheaves, where the rope leaves the drum, at drum crossovers, and at change of layer regions. When any visible condition that results in a reduction of rope strength is present, the affected portion of the rope shall be examined on a daily basis.
C. Before any person is hoisted with a newly installed wire rope or any wire rope that has not been examined in the previous 14 calendar days, the wire rope shall be examined in accordance with subsection B of this section.
D. At least once every six months, nondestructive tests shall be conducted of the active length of the rope, or rope diameter measurements shall be made:
1. Wherever wear is evident;
2. Where the hoist rope rests on sheaves at regular stopping points; and
3. Where the hoist rope leaves the drum at regular stopping points and at drum crossover and change of layer regions.
E. At the completion of each examination required by subsections B, C and D of this section, the person making the examination shall certify by signature and date that the examination has been made. If any condition listed in subsection B of this section is present, the person conducting the examination shall make a record of the condition and the date. Certifications and records of examinations shall be retained for one year.
F. The person making the measurements or nondestructive tests as required by subsection D of this section shall record the measurements or test results and the date. This record shall be retained until the rope is retired from service.
