Synthetic Rope: Inspecting a Synthetic Winch Line

INSPECTING SYNTHETIC WINCH LINE

Just like steel winch line, synthetic winch lines should be inspected prior to each use. When using synthetic winch line, be on the lookout for signs of damage or wear:

REGULAR WEAR

This is typical and has a slight fuzzy look or color fading caused by abrasion. The rope can still be used: Watch closely for further, more serious signs of wear.

COMPRESSION DAMAGE

This shows as a more visible sheen and stiffness than rest of the rope. This is often caused by setting the fiber around a winch drum or hook. Can be corrected: Bend rop back and forth to remove compression.

PULLED STRAND

A strand protruding from rest of rope. Can be corrected: Work the strand back in the rope by pulling back and forth.

CHEMICAL DEGRADATION

This shows as fused or bonded fibers, discoloration or brittleness. Replace this rope immediately.

HEAT DEGRADATION

Fused or melted fibers that are very stiff and can’t be loosened by bending. Replace this rope immediately.

INCONSISTENT DIAMETER

Tight flat areas that look like strand or strands have been pulled tight. These are typically caused by a broken or pulled internal strand or shock loading. Replace this rope immediately.

VOLUME REDUCTION/ CUT STRANDS

Reduced size of strands and/or rope diameter. These are broken strands caused by cuts, abrasion, sharp surfaces, or fatigue. When any strand is completely or partially cut, the entire line is compromised. Replace this rope immediately.
