It 11 hours ago · Lifting chain safety factor standards in 2026 ensure safe operations. Conversely, as the sling angle increases, the tension in the sling legs decreases, resulting in a lower load on each leg of the sling – and that increases capacity. It helps ensure safety, reduce stress on slings, and calculate the actual tension each sling will carry. EFFECTS OF SLING ANGLES SLING LIFTING CAPACITIES ARE AFFECTED BY ANGLE OF LIFT (ROUND SLING TO LOAD ANGLE) MEASURED FROM THE HORIZONTAL, WHEN USED WITH MULTI-LEGGED ROUND SLINGS OR CHOKER/BASKET HITCHES. Divide sling height* [H] by sling length* [L]. Historical Background In lifting operations, the angle of the sling can significantly impact the tension applied to the slings. Slings should never be used at angles less than 30 degrees. A sling angle of 60° or more is preferred. It is most desirable for a sling to have a larger angle of lift, approaching 90°. What sling angle is best for the lift? Figure 1 illustrates materials used to build a working model of a bridle sling to help learners visualize the way forces vary when loading angles change.
