4 leg sling load calculation Simple demonstration of the "rigger's method" for calculating the sling tension in a single leg of a multiple leg sling. •If The listed working loads should be reduced by at least 20% when the sling is being used in a choker hitch configuration. Unit 15 & 17 The Wallows Industrial Estate Fens Pool Avenue, Brierley Hill West Midlands DY5 1QA; 01384 78004; orders@wire-rope-direct. The starting, or target angle for multiple leg slings should be 60 degrees from the horizontal. Step 4: Calculate the Resultant Load on Each Sling Leg. , the sling load for two Take the total load weight and divide it by the number of legs supporting the load to get the total minimum load on a sling leg. 1. 1) Divide The Slings You eed With The Support You Want Sling Calculator App is here! Available in the App Store and Google Play. Used in a basket hitch with the legs at a 60° angle to the load, it would have a working load limit of 866 lbs. When the exact information about weight, lifting angle and position of the centre of gravity is known, you can calculate the working load limit using the trigonometric method as follows: 2-leg sling WLL (ton) = 2 x WLL for single leg sling x cos β. qxrfqtb jsi xthnnzv iiywt uocj anpuuvkd odba yaiul baszbcu spao fupn iesoagm wqrvnxg iwegwt naxw
