What can be a sign of wear on synthetic ropes?

Uneven coloring on synthetic ropes is a significant indicator of wear because it often indicates that certain areas of the rope have experienced more stress or abrasion than others. This uneven coloration can result from exposure to environmental factors, friction, or overloading, which can compromise the structural integrity of the rope. Assessing the color and condition of the rope is crucial for ensuring safety and preventing failures, as any variations can signal that the rope is no longer reliable for lifting or securing loads.

While remaining flexible is generally a good sign, it doesn’t necessarily indicate that the rope is in perfect condition. Light discoloration may occur without affecting the rope's overall performance, and the presence of knots can be part of normal use but does not inherently signify wear. However, testing and inspecting synthetic ropes for signs of damage like uneven coloring is key to maintaining safety in elevator operations.
