How can you identify if Manila rope is damaged?

Identifying damage in Manila rope is critical for ensuring safety and functionality, especially in applications like elevators where strength and reliability are paramount. The presence of dark brown and black spots on Manila rope indicates possible decay or mold growth, which is a sign that the rope may have been exposed to moisture or other conditions that could compromise its integrity. These discolorations show that the natural fibers may be breaking down, reducing the rope's ability to bear weight effectively.

Other characteristics, such as a smooth feel, fraying at the ends, or excessive stiffness, can also suggest issues, but the presence of dark spots is a more specific indicator of significant damage or degradation. A smooth texture could simply be a result of normal wear, fraying at the ends is not as immediately indicative of the overall condition as discoloration, and stiffness might relate to the rope's material aging but does not directly point to damage caused by environmental factors. Therefore, the presence of dark brown and black spots serves as an important warning sign of compromised rope integrity.
