Working Load Limit (WLL) vs. Minimum Breaking Strength (MBS)
Rigging engineering calculations are a critical aspect of ensuring the safety and efficiency of lifting operations. By understanding the types of calculations involved and the key considerations for performing these calculations, rigging engineers can ensure that lifting operations are performed safely and efficiently. For those interested in learning more, there are several free PDF resources available online that provide comprehensive guides to rigging engineering calculations.

At a angle, the tension rises to 7,070 lbs per sling. Working Load Limit (WLL) vs
When a load is lifted using multi-legged slings at an angle, the tension in each sling leg increases as the angle to the horizontal decreases. The formula to calculate tension ( ) on each leg of a symmetric sling system is:
Never guess the weight of a load. You must calculate it using the material's volume and density, or verify it via manufacturer shipping documents or certified crane scales. Weight=Volume×DensityWeight equals Volume cross Density Center of Gravity (CG)
When the Center of Gravity is closer to one side of the load, the slings will experience unequal tension. To find the tension on each side ( T1cap T sub 1 T2cap T sub 2 ) using a two-point lift: Calculate the share of the weight on Point 1 ( W1cap W sub 1 For those interested in learning more, there are
