Pulleys are tiny devices which hold the huge load of industry on its shoulders. Pulleys work in every industry through construction to mechanical and engineering works. Pulleys are considered as useful mechanical device to lift the huge weight of mechanical engines and other equipments, while in construction; masons use pulley to lift their tools and construction material while making roof or working on large buildings. In some other ways pulleys are used to lift the people from the ground to last floor and from last floor to ground or it can be underground. Pulleys are widely used in buildings to work as a lift. Hotels and restaurants use pulleys for avail much time by reducing their lifting of their hotel equipments. Pulleys are commonly used as a construction machinery part. Pulleys are use to shift the large weight with less force.
Who was Archimedes? Archimedes was the inventor of pulley. In 287 BC, Archimedes named scientist was born in Syracuse. Archimedes was also the revolutionary inventor of Pumps and Levers. King of that time challenged Archimedes to pull the huge ship full of passenger and cargo. He did it! He amazed the crowd and King gathered around him.
What is Pulley? Pulley consists of two flanges hold tightly shaft, and shaft has small bearing or wheel on it. A deep part of that bearing or wheel builds to hold the rope or cable. Cable or rope is the part of pulley which lifts the weight. Pulleys are used transfer the huge weight to small bearings. In some manners pulleys are used to transfer the large weight in different short distance locations. These kinds of pulleys called Differential Pulley or Chain Hoist.
Main types of pulleys are Cable Pulleys, Cone Pulleys, Conveyor Pulleys, Drive Pulleys, Elevator Pulleys, Fan Pulleys, Grooved Pulleys, Miniature Pulleys, Plastic Pulleys, Rope Pulleys, Shaft Pulleys, Steel Pulleys, V-Belt Pulleys and Wood Pulleys. Fixed Pulley is used to move the belt on fix shaft. These pulleys considered as a best in mechanical industries because the equal force lies on both side of pulleys. Compound pulleys are combination of two or more belts and pulleys on a single shaft, huge electrical pumps with maximum HP use these kinds of pulleys. Moving Pulleys use moving shaft which is moving freely in any direction. If one end of rope is busy on the anchors pulley will apply the load on other end of the rope automatically.
Globally, many Exporters, Manufacturers, Wholesalers, Traders, Suppliers and Distributors provide pulleys to all over the world with various B2B Platforms. Various Chinese companies produce 2 million of pulleys per year.
