The manufacturer, CMI, does not provide a Working Load Limit (WLL) for this pulley system. But, we do have some general information for you on the components. Both the upper and lower pulleys have a Minimum Breaking Strength (MBS) of 11,000 lbs. So if you figure 10% of that (most figure between 5% - 15%) you get 1,100 lbs for the pulleys. The rope carries an MBS of 5,500 lbs so again, figure 10% of that which is 550 lbs.
