In this case, the lifting beam is subjected to 1000 tonnes (Note: the two pad eyes that transfer the load is subjected to 500 tonnes each). In the previous lecture, we explored simple trigonometric formulas for estimating the working loads of slings. If appropriate overhead clearance is available, most riggers use a 60° equilateral triangle as a benchmark angle. I have made this simple spread sheet to calc it. This calculator is used where 4 slings will be attached to a load that has 4 attachment points that are equal distances from the load's Centre of Gravity. To calculate the SWL of a sling needed to lift a load, divide the load by the angle factor and divide by the reeve factor. As an example, a horizontal sling angle of 30° will increase the tension factor by 2 times therefore doubling the weight felt by the sling and all related rigging. Determine the style sling you’ll be using (chain, wire rope, or synthetic) and hitch type (vertical, basket, or choker). Though most manufacturers do states the S.W.L (Safe Working Load) of every sling wire, in some circumstances the information may be missing. The distance between the attachment points that run along the load, the distance between the attachment points that run across the load, and the load weight must be known values, and a desired sling angle must be selected. Many riggers follow this model for quad leg slings of any material, relying on the fourth leg for stability only. • Ensure that the chain is free of twists and is protected from any sharp corners on the load. The included angle is the angle created between opposite sling legs (ex. Related Topics . It’s important to understand the different angles that will impact the load to lift.
