Sometimes after a rappel, you try to pull your rope, but it's stuck. No matter how hard you pull, the rope doesn't slide through the anchor. The most common scenarios that lead to stuck ropes include:
Long rappels (the rappel strand can get very heavy)
Anchors located above a ledge (the rope rubs on the ledge)
One way you can try to free your rope is to set up a 3:1 pulley system to multiply your pulling force. The figure to the right shows how to set up this pulley system.
