Rated capacities are affected by angle of lift (roundsling to load angle) measured from the horizontal when used with multi-legged roundslings or choker/basket hitches. To determine the actual capacity at a given angle of lift, multiply the original roundsling rating by the appropriate loss factor determined from the table below.
