Have you ever needed to determine the sling length for a desired angle of loading (horizontal sling angle), but perhaps struggled with how to get the correct answer?
If so, hopefully you will find the information below of benefit.
First, you will need to know four pieces of information:
1. Location of center of gravity (COG)
2. Desired sling angle
ASME B30.9 now calls the horizontal sling angle, the angle of loading.
3. Length factor (L/D) for the desired angle of loading
Do not sweat this one, the math geeks have already provided this information for you below.
4. Distance from pick point on the load to COG
This distance is the “D” in the examples below.
