Wire Rope Inspection and Maintenance
Your Lift’s Cables, which are wire rope, should be inspected regularly:
Wire rope should be replaced when there are visible signs of damage or extreme wear.
Do not use
the Lift if it has damaged or worn Cables
;
take it out of service!
Wire rope should be maintained in a well-lubricated condition at all times.
Wire rope is only fully protected when each wire strand is lubricated both internally and externally.
Excessive wear shortens the life of wire rope. Use a wire-rope lubricant that penetrates to the core
of the rope and provides long-term lubrication between each individual strand, such as 90-WT
gear oil or ALMASOL® Wire Rope Lubricant. To make sure that the inner layers of the rope remain
well lubricated, lubrication should be done at least every three months during normal operation.
All Sheaves and guide rollers that contact moving wire rope should be given regular visual checks
for surface wear and lubricated to make sure they run freely. This should be done every three
months during normal operation.
For all sheave axles, use standard wheel bearing grease. For all Sheaves and/or guide rollers, use
90-WT gear oil or a similar heavy lubricant, applied by any method including pump/spray
dispensing, brush, hand, or swabbing.
How often should you inspect?
Wire rope should be visually inspected at least once each day when in use, as suggested by
American Petroleum Institute’s Recommended Practice 54 guidelines. Any wire rope that meets
the criteria for removal must be immediately replaced.
When should you replace wire rope due to broken wires?
Wire rope should be removed from service if you see six randomly distributed broken wires within
any one lay length (where a single strand makes a full turn around the rope) or three broken wires
in one strand within one lay length.
Are there other reasons to replace your wire rope?
Yes. Corrosion that pits the wires and/or connectors, evidence of kinking, crushing, cutting, bird-
caging, or a popped core, wear that exceeds 10% of a wire’s original diameter, or heat damage.
How do you find broken wires?
a.
Relax your rope to a stationary position and move the pick-up points off the Sheaves. Clean
the surface of the rope with a cloth — a wire brush, if necessary — so you can see any breaks.
b.
Flex the rope to expose any broken wires hidden in the valleys between the strands.
c.
Visually check for any broken wires. One way to check for crown breaks is to run a cloth along
the rope to check for possible snags.
d.
With an awl, probe between wires and strands and raise any wires that appear loose.
