This is very critical and one need’s to have a degree of expertise to ascertain the quality and various attributes of the rope.
Sharp bends around any equipment should be avoided as, under load, it decreases rope strength substantially and may cause premature damage and failure. The diameter on fixed pin termination should be at least 3 times the rope diameter and on rotating sheave blocks, it should be 10 times the rope diameter for twisted ropes and 8 times the rope diameter for braided ropes.
For the long life and to maintain the effectiveness of the rope below measures are highly recommended:
Working loads are the loads that a rope is subjected to when in activity. They are normally expressed as a percentage of new rope strength and should not exceed 20% of published strengths. (Many industries are subject to special working loads regulations that supersede a manufacturer’s recommendation.)
When severage due to overloaded or shock loads take place, the rope can suffer damages and consequently strength losses without any visible indication, which may weaken the rope and cause it to break during its next use even if used under normal working loads. Sharp bends should be avoided as, under load, it decreases rope strength substantially and can cause premature failure
Handling is a very important criteria, to maintain the life and quality of the ropes, below are some pre-requisites for effective handling of the ropes:
