ROPE INSPECTION & RETIREMENT
One frequently asked question is, “When should I retire my rope?” The most obvious answer is, “Before it breaks.” But without a thorough understanding of how to inspect it and knowing the load history, you are left making an educated
guess. Factors such as load history, bending radius, abrasion, chemical exposure, or some combination of those factors, make retirement decisions challenging.
Inspecting your rope should be a continuous process of observation before, during, and after each use.
In synthetic fiber ropes, the amount of strength loss due to abrasion and/or flexing is directly related to the amount of broken fiber in the rope’s cross-section. After each use, look and feel along every inch of the rope length inspecting for
cut strands, compression, pulled strands, melted or glazed fiber, discoloration, degradation, inconsistent diameter and abrasion. Glossy or glazed areas, inconsistencies in texture, and stiffness are indicators that the rope has been subjected to
elevated temperatures, has embedded grit, or has been subjected to shock loading and possible loss of strength.
Samson recommends splicing as the preferred rope termination method. Knots can significantly decrease a rope’s strength while, in most cases, splicing maintains 100% of the specified rope strength. Splice terminations are used in all our ropes to
determine new and unused tensile strengths.
ROPE INSTALLATION CONSIDERATIONS
Prior to use, application specifics should be reviewed to understand the method of installation needed to ensure proper rope performance. Depending on the intended use, installation considerations may include but are not limited to:
- Establishing proper tension and length (i.e., static applications)
- Connection mechanism (i.e., winch drum, spliced thimble)
- Back tension is required to ensure effective spooling (when utilizing product on a winch)
Rope performance will be influenced by the level of attention given to these factors during the installation process. It is highly recommended that the rope manufacturer be consulted if the user lacks experience handling and installing high-performance
End-for-ending is commonly used to shift the outboard and inboard ends of a line at a single service location. By reversing the line, worn/damaged rope sections are moved to less demanding conditions. The recommended end-for-ending period will be
highly dependent upon the nature of the service location, frequency of use, ability to perform the end-for-end process, and other factors, but it is recommended to occur at, or near, the midpoint of the line’s expected service life.
