SLING CONSIDERATIONS • EFFECTSOF SLING ANGLES REDUCTION IN CAPACITY - MULTI-LEG SLING REDUCTION
The capacities of all slings are affected by the angle of the lift(sling to load) measured from the horizontal. Todetermine the actual capacity of a multi-leg sling at a given angle, multiply the vertical single leg sling capacity by the number of legs being used (this can be no more than three for chain slings). Multiply this total by the appropriate loss factor listed below.
