When slings are used in a bridle at an angle, the To determine capacity at an angle, multiply the rated capacity by the angle factor in the charts. Learn how to calculate sling angles and their effects on sling tension and capacity using a chart and formulas. Increasing the angle between the sling legs reduces the lifting capacity. Always consult your SpanSet lifting chart. a. Sling One of the most overlooked considerations when designing a rigging system is sling angles. Never use damaged slings. The Increased Tension method provides the increased tension as a Avoid sling failures: master sling angle formulas, load charts, and ASME B30. Slings should never be used at angles less than 30 degrees. So, one would wonder what happens when the angle of lift goes below 30 degrees? A chain sling lifting at a 20 Determine the sling angle from the horizontal and the corresponding tension multiplier (from the chart below). Multiply the sling leg’s share of the load by the tension multiplier to determine the increased . 9 safety rules. Using the angle from horizontal, read across the angle chart to the corresponding number in the Tension Factor column. OR b. If the angle of the sling is not taken into consideration before selecting a sling to lift a A Great pocket reference guide - for all types of slings, sling hardware, and accessory equipment. When slings Work out the Safe Working Load of webbing & round slings using the Load Chart. Safety Factors inc the angle of lift, legs, colour coding, pull and more. Sling capacity decreases as the angle from horizontal decreases. As the angle from horizontal decreases, the reduction factor decreases Other ways of calculating the sling angle include using a protractor or a sling angle chart provided by your sling's All sling angles as mentioned in this catalogue are measured from the horizontal. A Do not exceed rated capacities. If you can measure the angle of lift or the length and height of the sling as rigged, you can determine the properly rated sling for your lift. It is important to pay close attention Sling Load Chart As the sling-to-load angle decreases, so does the rated capacity of a sling. Accurate angle measurements can help avoid overload risks and ensure secure When computing sling capacities always take this most important factor into account. The Slingmax Rigging Handbook has This is why an alloy chain sling should never be used at a lifting angle below 30 degrees. Do not, under This angle, which is measured between a horizontal line and the sling leg or body, is called sling angle or horizontal angle as shown below. As can be seen from the table, sling stresses increase tremendously Home » Info & Services » Rigging & Lifting Warnings and Information » Load Angle Chart Also, the chart shows the sling angle and how much the sling can lift from that angle. Learn how to calculate sling angles for safe lifting. Sling’s working load Padding must be used to protect the slings. Updated 2025 guide with mobile apps & tools included. Not sure if your lifting safely with textile slings? Here This chart shows the relationship between sling angle, reduction factor, and tension factor. Example: Although looking at this chart is pretty Level Pick Points & Different Sling Angles Formula Key Principle When pick points are at different distances from the center of gravity, the sling tensions vary The Sling Angle Calculator helps calculate the sling angle, which is essential for safe and efficient rigging during lifting operations. As the angle decreases the stress imposed on the leg of a sling increases. For example, a sling rated at 5,200 lbs in a basket hitch would have When a multiple part sling is to be used at some angle other than zero degrees or 45 from the vertical, the proper sling size can be chosen by applying the Always work within the WLL of your slings. Learn safe ranges (45°–60°) and apply results in your lift plan. See examples of reduction This guide will help you understand the importance of sling angles, how to use them in determining the right capacity lifting Calculate sling angles, leg tension, and reduction factors with worked examples. Lifting Weight [LW] x the The load configuration chart are essential in the calculation of the load to be lifted and the choice of the sling. Use this chart for all type slings: rope, chain or synthetic web. The sling capacity DECREASES as the horizontal angle DECREASES. Divide sling length* [L] by sling height* 3.
