- Lifting sling angle chart. It is most desirable for a sling to have a larger angle of lift, approaching 90°. To determine the actual capacity at a given angle of lift, multiply the original sling rating by the ap-propriate loss factor determined from the table. mechanical chain 6:20 – Does a hitch affect the limit of a sling angle? 8:20 – Sling Working Load Limits Chart 9:30 For choker hitch, the angle of choke shall be 120 degrees or greater. Calculates sling loads with 2 or more slings, at different angles for a given weight. Always read and ensure the instruction is understood before lifting of payload commences. Example: The sling cradles the load while both eyes are attached overhead. Understanding LOAD CALCULATOR Rated Capacities for Slings Use the following calculator to determine the rated capacity required by the sling (s). All other things being equal, the flatter, or more severe, the sling angle, the lower the lifting capacity of the sling. How to Select a Sling for Use at Any Angle When calculating for selection of the proper sling, select the vertical angle in the chart at left. The load on each leg must be calculated based on the position of the slings and the location of the lift’s center of gravity. s6g pr8k 9ij4 qvrv ip9 w75 e6ln z2bu2q gheu b4cnxuq0
