How to Identify and Address Cable Birdcaging Issues

What is the term used to describe a cable sling with untwisted strands in a section?

a) Cable degradation

b) Cable fatigue

c) Cable birdcaging

d) Cable corrosion

Answer:

The correct answer is c) Cable birdcaging, a condition where the strands of the cable become untwisted in a section, resembling a birdcage-like formation.

When a cable sling is found with the strands becoming untwisted in a section, the problem is referred to as "Cable birdcaging." This phenomenon occurs when the individual strands of a cable separate or become untwisted, creating a birdcage-like appearance. This can weaken the cable's structural integrity and is a significant concern in industries where cables are used for lifting, rigging, or supporting heavy loads.

Cable birdcaging can be caused by various factors, including overloading, improper use, or wear and tear over time. It is essential to inspect cables regularly for signs of birdcaging and address the issue promptly to ensure the safety and efficiency of any operations relying on cables.

Imagine a cable with multiple strands twisted together. When these strands start to untwist and separate in a section, it resembles a birdcage. This weakens the cable's ability to evenly distribute the load, making it susceptible to failure. Addressing cable birdcaging promptly is crucial to maintaining safety and functionality in various industries.
