Sling Angle Factor. To determine if a particular sling will have the capacity required,


To determine if a particular sling will have the capacity required, take the angle between the sling leg and the horizontal, then multiply the sling’s rating by the factor provided in the accompanying table. This angle plays a crucial role because it directly affects the tension in each sling leg. It accounts for the increased tension that occurs as the angle from horizontal decreases. This distance is the “D” in the example below. However, angles between 60° to 90° are generally considered safe. Learn how to calculate sling angles for safe lifting. Sling Specification Tables - Sling tables throughout our site contain the Working Load Limits of slings rigged with these hitches at certain specified angles.

Learn more about wire rope hitch types, sling angles, bridle angles, sling eye design and more The sling angle factor is a ratio of the side of the lift triangle, which in this case is the sling, and the height of the triangle. As early as the construction of ancient pyramids, the principles of angles and leverage were utilized, although the formal calculation methods have been developed with the advancement of physics and engineering disciplines. As this angle decreases, the stress on each leg increases with the same load.
