The sling angle is ?.

The sling angle is ?.

• A. the acute angle between the horizontal and the sling leg
• B. not necessary to determine a rated load
• C. the L/H ratio
• D. the ratio between the hypotenuse and the opposite legs of a right triangle

Answer: (A)

Sling angle is the acute angle between the sling leg and the horizontal. This angle is crucial because it determines how much vertical lift each leg contributes for a given load; as the sling angle becomes smaller (slings closer to the horizontal), the required tension in each leg increases, reducing the overall rated load capacity. In practice, you use this angle to read rigging charts and ensure the lift is within safe limits for the equipment and setup. It’s not a length ratio or a simple ratio of sides in a right triangle, and the angle must be known to determine the correct load rating.
