Refer to this link to utilize the NIOSH Lifting Equation calculator from the Canadian Centre for Occupational Health and Safety. As long as you have taken the lift factors measurements, this site will allow you to calculate the Recommended Weight Limit by selecting values from drop down menus. The site explains how to measure and collect the lift factors under the Assessing Relevant Handling Factors link displayed on the left column.
