What could lead to increased tension in sling legs during operation?

The correct answer is related to the concept of rigging angles, which have a significant impact on the distribution of forces in a sling system. When the rigging angle is incorrect, it can lead to increased tension in the sling legs.

For instance, as the angle of the sling legs decreases from the horizontal, the tension in the sling legs increases due to the geometry of the load being lifted. A steeper angle causes more vertical force to be exerted on the sling, leading to higher tension. This can result in overloading the sling and potentially compromising the safety of the lifting operation. Maintaining the correct rigging angle is crucial for ensuring that the tension is evenly distributed and within the safe operating limits of the slings used.

Understanding the proper rigging angles helps technicians ensure safety and efficiency in lifting operations, and it illustrated the importance of following established guidelines for sling usage.
