When using cable or nylon spreaders, what happens as the spreader angle decreases?

As the spreader angle decreases, the tension in the cables or nylon spreaders actually increases. This phenomenon occurs because a smaller angle results in a greater amount of vertical force needing to be counteracted by the horizontal components of tension in the lines.

When the angle between the load and the spreader becomes smaller, the load is essentially spread out more, leading to the cables having to carry a greater share of the load's weight directly. Therefore, the tension must increase to maintain stability and support the load effectively.

Understanding the relationship between angle and tension is crucial for safe operation and load handling, as excessive tension can lead to equipment failure or accidents if not properly managed.
