What is the load limit of the pully and will it work with 3/16 in wire rope?

I used three of these in a lift system on my workshop, i figured it would be rated same as the heavy duty rigid and swivel of 480lbs, but they are not. I want to 240, they are mounted up high and using three of these plus two swivel to make the lift system, was plenty. Respond to this and i will climb up and verify on ones i have. Other half, can use up to a 3/8 rope or chain rope in these. Also, be sure to use 3 screws to attach to either ceiling or wall. Mine are overhead. The wheel/pin assembly is easy to take apart and put together.
