Product Summary

A single crane pulley would be one pulley attached to a fixed point with a rope running over top of it. The object would be attached at one end and a person or machine would pull on the other. In this case, there is no effort saved in using the pulley system. This type of system only saves energy in that pulling down on the rope is easier than pulling up on the object.

In a system of a single crane pulley, when friction is neglected, the mechanical advantage gained can be calculated by counting the number of rope lengths exerting force on the load. Since the tension in each rope length is equal to the force exerted on the free end of the rope, the mechanical advantage is simply equal to the number of ropes pulling on the load. For example, in Diagram 3 below, there is one rope attached to the load, and 2 rope lengths extending from the pulley attached to the load, for a total of 3 ropes supporting it. If the force applied to the free end of the rope is 10 lb, each of these rope lengths will exert a force of 10 lb. on the load, for a total of 30 lb. So the mechanical advantage is 3.
