A chain pulley is a simple tool, which eases the human effort of lifting an object. Used for centuries in the shipping and manufacturing industries, it uses the simple principles of physics and geometry to lift the object. It is first needed to be decided what type of chain is needed depending upon the type of job at hand. Chains can be of different sizes, thinner as well as thicker. Thinner chains are required when the object is lighter, and the object is to be lifted quickly whereas thicker chains are required when the need of lifting massive objects arise.
