5) Rope should be maintained in a well-lubricated condition. Gorbel recommends using Chain and Cable
Penetrating oil for lubrication. Lubricant applied as part of a maintenance program shall be compatible with the
original lubricant. Lubricant applied shall be of the type that does not hinder visual inspection. Immediately after
inspection, lubricant shall be applied before rope is returned to service. Those sections of rope that are located
over sheaves or otherwise hidden during inspection and maintenance procedures require special attention when
lubricating rope. The object of rope lubrication is to reduce internal friction and to prevent corrosion.
WIRE ROPE REPLACEMENT CRITERIA
1) No precise rules can be given for determination of the exact time for rope replacement, since many factors are
involved. Once a rope reaches any one of the specified removal criteria, it may be allowed to operate to the end of
the work shift, based on the judgement of a qualified person. The rope shall be replaced after that work shift, at the
end of the day, or at the latest time prior to the equipment being used by the next work shift.
2) Removal criteria for the rope replacement shall be as follows:
(a) in running ropes, 12 randomly distributed broken wires in one lay or four broken wires in one strand in
one lay (
reference Diagram E below
);
(b) 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;
(c) wear of one-third the original diameter of outside individual wires;
(d) kinking, crushing, birdcaging, or any other damage resulting in distortion of the rope structure;
(e) evidence of heat damage from any cause;
(f) reductions from nominal diameter greater than those shown below:
Maximum Allowable
Reduction From
Rope Diameter
Nominal Diameter
Up to 5/16 in. (8 mm)
1/64 in. (0.4 mm)
3) Broken wire removal criteria applies to wire ropes operating on steel sheaves and drums. However, results of
internal testing have shown that rope replacement follows the same criteria regardless of sheave or drum
material.
4) Attention shall be given to end connections. Upon development of two broken wires adjacent to a socketed end
connection, the rope should be resocketed or replaced. Resocketing shall not be attempted if the resulting rope
length will be insufficient for proper operation.
5) Replacement rope and connections shall have strength rating at least as great as the original rope and
connections furnished by the hoist manufacturer. A rope manufacturer, the hoist manufacturer, or a qualified
person shall specify any deviation from the original size, grade, or construction.
