WebDivide the weight of your total load by the number of legs you are using. This gives you the load per leg if the lift were being made with all legs lifting vertically. 2. Measure the angle between the legs of the sling and the horizontal plane. 3. Multiply the load per leg that you calculated in step 1 by the load factor for the leg angle you ... Web7 rows · LOAD ON EACH LEG OF SLING =. (Load 2) x LOAD ANGLE FACTOR. ANSI B30.9 recommends against the use of a horizontal sling angle smaller than 30.
WebJan 27, 2014 · Anytime pull is exerted at an angle on a leg—or legs—of a sling, the load per leg can be determined by using the data in the table above. Proceed as follows to calculate this load—and determine the rated capacity required of the sling, or slings, needed for a lift: First, divide the total load to be lifted by the number of legs to be used.
