4. Its functional principles could be summarized like this: when the number of wire-rope strands is odd, the rope end should be fixed on the movable pulley, and when the number is even, the rope ends should be fixed on the fixed pulley; when the number is even, should reduce one fixed pulley; when the pulling direction is opposite to the moving direction of weights, should add one fixed pulley.
