If your synthetic rope shows signs of damage, replace it immediately.
A brand new synthetic winch rope will naturally “fuzz up” when you first use it. This fuzzy texture is considered a sign of normal wear. Instead of being something you should worry about, this roughing up is actually a good thing, because it protects the fibers underneath. The rope should quickly fuzz up and stabilize, without excessive roughing. If the surface of the rope continues to roughen up instead of stabilize, look for the source of excessive abrasion.
As you inspect the rope, take a close look at both the inner and outer layers of fiber. Signs of weakness, excessive abrasion, broken fibers, or other wear in either layer should alert you to obvious damage. Separate the strands to inspect the inner layers of the rope. If the fiber inside is powdery, the rope is significantly weakened and needs to be replaced.
When should you replace a synthetic winch rope?
Look for these signs of obvious damage:
- Significant abrasion anywhere along the length of the rope
- Two or more strands are cut
- Permanent flat areas or bumps (Flex the rope to eliminate these. If the flat area or bump is not eliminated by flexing, the rope is weak or damaged.)
- Large section of melted fibers (Look for a shiny appearance or stiff rope.)
Other changes in appearance, such as discoloration from chemical exposure (i.e. motor oil or fluids), may also be signs of weakness or damage. In short, if the appearance of the rope leaves you doubtful of its condition, ask for the opinion of a qualified technician or simply replace the rope. Better safe than sorry.
