Inattention to the effect of sling leg angle can result in sling overload. Never used damaged slings. • Position the sling so that the load is uniformly spread over its width and protect the The calculator estimates the sling angle, providing the angle formed between the vertical line and the sling when lifting a load. The lower the angle (from horizontal), more tension (force) exerted onto the sling. This is shown in the load chart below. So, lifting a 1te load with slings at a 45° angle gives a mode factor of 1. Increasing the angle between the sling legs reduces the lifting capacity. When using slings in choke hitch multiply the marked SWL by 0. By following Working Load Limit (WLL): Double the vertical hitch WLL for a 90° sling angle. The angle at which a sling is used affects the sling’s tension and the lift’s safety. Key points include inspecting slings prior to each use and at least annually, understanding how sling angles affect load capacity, Regular inspections and maintenance of slings are also crucial for safe lifting. Multi-Leg Sling Angle. case of multi-leg slings the specified angle or range of angles. As the sling angle decreases, the load capacity increases. The optimal sling angle is 90 degrees—this is when the sling is completely vertical, placing no additional tension on When you’re lifting at a 60° angle, you have to use a multiplier to get that tension. Using more than two slings. , but the angle affects that capacity. The multiplier for a 60° angle is 1. Chain sling WLL is to be reduced in accordance with TABLE 5 when Find out how connection methods affect lifting angles. That process starts with a “Critical The Sling Angle Calculator helps calculate the sling angle, which is essential for safe and efficient rigging during lifting operations. 155. o.
