What is the maximum angle for a slings system to maintain its rated capacity?

A sling system's rated capacity is most effectively maintained at an angle not exceeding 60 degrees. When the angle increases beyond this, the vertical component of the load decreases, which can potentially lead to overloading the sling itself. At 60 degrees, the tension in the sling is still within acceptable limits, allowing it to safely carry the intended load.

As the angle approaches 90 degrees, the lifting capacity of the sling diminishes significantly, and the potential for the load to swing or shift increases, creating further safety risks. Therefore, maintaining a maximum angle of 60 degrees is crucial for ensuring the integrity and safety of the lifting operation.
