For extra quality resources on rigging engineering calculations, consider the following:
: These guides explain how to determine the stress on individual sling legs based on the load weight and the horizontal angle of the hitch. Center of Gravity (CG) Determination : Basic workbooks, such as the one from BNL Training
In multi-point lifts, engineers must calculate how much weight each point carries, especially if the load is asymmetrical.
Instead of a static download, users access a web-based calculator.
