We bought the Petzl Oscillante Pulley for our Boy Scout Troop with the intent to use it for a zip line. The rope was tied from a tree on one side of the gulley to a tree on the other side of the gulley. We created a rope harness that the scouts sat in and attached the harness to the pulley with a carabiner. The carabiner also had two ropes attached to it to pull it back and forth across the gulley. One rope given to scouts on one side and the other given to scouts on the other side. At the end of the day, I looked at the pulley and it appeared as in the picture attached. The rope had melted the pulley wheel and even started melting through the metal pin holding the pulley assembly together (thru the pulley wheel). When we first started using it that day, the pulley seemed okay on the rope. I believe that the rope was within the limits described. Any thoughts? This definitely didn't work out the way we had hoped.
