Sling Lifting load calculator for precise sling forces, angles, and center of gravity. Any angle other than vertical (sling angle = 90º) at which the sling is rigged, This chart shows the relationship between sling angle, reduction factor, and tension factor. Features Calculate the Sling to Load Angle (see below — Sling To Load Angle). Professionals in construction, shipping, or heavy machinery use it to determine sling tension, load capacity, or the correct sling length. Multiply the load weight by the tension Sling Angle is the angle measured between the horizontal plane and the sling leg or body. As the Sling-To-Load Angle decreases, the . For this reason, when the center of gravity is closer to one point of the sling attachment than to the other, the slings must be of unequal length. Intended for safety professionals preparing for certification exams. When slings are used in a bridle at an angle, the SLING TENSION To determine the load on each sling when using a two-leg bridle, the formula is: load weight x sling length number of slings x height from load to hook Note: The length of any hardware Calculate sling angles and tension forces quickly with our free Sling Angle Calculator. Calculate sling angles, leg tension, and reduction factors with worked examples. Discover the wire rope sling load capacity chart from 8mm to 80mm as per Indian Standards IS 2762 with their Safe Working Load at different angles Sling Angle The loading in any type of sling is affected by the angle of the sling leg. . The tension on each leg of the sling is increased Calculates sling tension by using sling angle or sling length and height. You can use the chart below to calculate tension factors. When selecting a sling to carry a given load, it is Below are two Rigging Wall Charts from Lifting Gear Hire. The second Lifting load calculator for precise sling forces, angles, and center of gravity. Determine the sling angle from the horizontal and the corresponding tension multiplier (from the chart below). Example: Although looking at this chart is pretty Sling Angle Factor What is a Sling Angle Factor? Simply put, the sling angle factor (SAF) is the multiplier used to determine the additional tension on a sling (or other rigging hardware) EFFECT OF SLING ANGLE Using slings at an angle can become deadly if that angle is not taken into consideration when selecting the sling to be used. The first chart covers some basic Center or Gravity and Weight of Material. Updated 2025 guide with mobile apps & tools included. Determine the associated tension factor (see chart). Ideal for rigging, crane work, and planning asymmetrical lifts. Web Sling Inspection . The Northern Strands Sling Tension Calculator has been designed to assist you in selecting slings with enough load carrying capacity for your lifting applications. Useful when you do not know the actual sling angle. 9 safety rules. Learn safe ranges (45°–60°) and apply results in your lift plan. Lifting load calculator for precise sling forces, angles, and center of gravity. As the angle from horizontal decreases, the reduction factor decreases When selecting a sling, always consider the Sling-to-Load Angle and the tension that will be applied to the sling. Perfect for riggers, crane operators, and engineers. Multiply the sling leg’s share of the load by the tension multiplier to determine the increased Avoid sling failures: master sling angle formulas, load charts, and ASME B30. Calculate sling angles and tension forces quickly with our free Sling Angle Calculator. One of the most overlooked considerations when designing a rigging system is sling angles. If appropriate overhead clearance is available, most riggers use a 60º equilateral SLING TENSION To determine the load on each sling when using a two-leg bridle, the formula is: load weight x sling length number of slings x height from load to hook Note: The length of any hardware Also, the chart shows the sling angle and how much the sling can lift from that angle. 52 Web Sling Repairs 52 Synthetic Tiedown Assemblies Simple demonstration of the "rigger's method" for calculating the sling tension in a single leg of a multiple leg sling.
