Therefore, when adjusting the working load limit of four leg chain slings, the number of legs in the calculation must be 3 not 4. Many riggers follow this model for quad leg slings of any material, relying on the fourth leg for stability only.Choke Angle - When lifting or turning a load rigged with a choker hitch, the angle at which a sling is turned back on itself can reduce it's capacity below what is listed for its choker hitch, if the angle is too severe. When a load is allowed to hang free, the natural choke angle is about 135°.If the angle is less than 120°, you must adjust its Choker Hitch Working Load Limit by the appropriate choke factor from this table.Choker Hitch WLL x Choke Factor = Adjusted WLLChoker Hitch Rated Capacity - A choker hitch will have 75% of the capacity of a single leg vertical hitch only if the corners are softened and the horizontal angle is greater than 30°.More Information:Rigging With SlingsSlings - IntroductionSlings - Warnings & Safe Operating TipsWire Rope Slings - IntroductionWire Rope Slings - WarningsChain Slings - IntroductionChain Slings - WarningsWeb Slings - IntroductionWeb & Round Slings - WarningsRound Slings - Introduction
