Ramsey Winch PATRIOT 9500 W_SYNTHETIC ROPE - Manual (Page 7)

Rope Inspection
When rope is first used, the outer filaments of the rope will quickly fuzz up. This is the result of these filaments
breaking and this roughened surface will actually protect the fibers underneath. The condition should stabilize, not
progress. If the surface roughness increases, excessive abrasion is taking place and strength is being lost.
Look closely at both the inner and outer fibers. When either is worn the rope is obviously weakened. Open the
strands and look for powdered fiber--this is a sign of internal wear.
Rope should be replaced when
· Rope bulk anywhere along the length is reduced by 25% or more by abrasion
· Two or more adjacent strands are cut.
· Flat areas or lumps are found that are not eliminated by flexing rope.
· Excessive fused or melted fibers are found. Any such areas will be stiff and the rope will have a
glazed appearance.
Examples:
Rope with original bulk
Rope displaying 25% strand volume reduction from abrasion--rope should be
replaced.
Rope strand showing full volume
Rope strand reduced by 25% abrasion--rope should be replaced.
Rope exhibits fiber-set from compression. A slight sheen is visible. This is not a
permanent characteristic and can be eliminated by flexing the rope.
Rope displays two adjacent cut strands--rope should be replaced.
