The pulley group is composed of several fixed pulleys and moving pulleys, which can save effort and change the direction of force. In use, how much it save and rope winding, determine the use of pulley group effect. The pulley is borne by two ropes, that is, each rope bears the force of the object and the moving pulley, which is a fraction of the total weight of the object and the moving pulley.
