Working Load Limit (WLL) is the maximum working load designed by the manufacturer. This load represents a force that is much less than that required to make the lifting equipment fail or yield. The WLL is calculated by dividing MBL by a safety factor (SF).
It is a calculation of the Minimum Breaking Strength, Minimum Breaking Load divided by a safety factor, usually ranging from 4 to 6 on lifting equipment. The factor can be as high as 10 to 1, if the equipment has poses a risk to a persons life.
