(a) At least once every fourteen 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.
(b) Before any person is hoisted with a newly installed wire rope or
any wire rope that has not been examined in the previous fourteen calendar
days, the wire rope shall be examined in accordance with paragraph (a) of
this section.
(c) 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;
(3) Where the hoist rope leaves the drum at regular
stopping points; and
(4) At drum crossover and change-of-layer regions.
(d) At the completion of each examination required by paragraph (a)
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 paragraph (a) of this standard 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.
(e) The person making the measurements or nondestructive tests as
required by paragraph (c) 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.
