Lifting Equipment A Brief History of the Development of Lifting and Handling Machinery
Release time：2021-06-28
China has a longer history in the invention and use of lifting equipment to lift and carry machinery. As early as the end of the Neolithic Age, laboring people in China could carry huge stones by rolling sticks. In the Shang Dynasty, people invented the Jucotton which used the principle of counterweight lever, and then invented the rolling fistula. In the Han Dynasty, the hoisting device composed of winch and pulley was widely used in the salt mining process of Sichuan Wells. The stable structure form of derrick and cable wind rope composed of wooden pole (towing rope) is the ancestor of today's hoisting equipment, lifting and handling machinery. The Great Wall of China, the underground palaces, the Forbidden City, the huge cast bells in the bell towers of ancient capitals and the hoisting of hundreds of tons of cast statues all reflect the wisdom of the Chinese working people.
When the ancient Egyptians were building the pyramids, they had used unequal levers, rollers and inclines to lift the stones step by step. During the industrial revolution in the 18th century, metal materials were used in the manufacture of lifting equipment, lifting and carrying machinery, and cranes were driven by steam. Due to the long bondage of the feudal system, China could not develop social production and science and technology. In old China, even simple lifting equipment, lifting and handling machinery were not manufactured.
After the founding of New China, China in the field of lifting equipment lifting and handling machinery also from scratch, from small to large gradually developed, a number of lifting and transport machinery research institutions and production factories are gradually established, the design, research and development strength is growing. Today, China has been able to design and manufacture lifting mass of 3~100t of various types of automobile and tyred cranes, lifting mass of 10 ~ 400t of various types of tower cranes, lifting mass of 200~800t of portal and bridge cranes, lifting mass of 500t of floating cranes, lifting mass of 350t of mast, The lifting quality of 450t of the highway flat truck, to meet the growing equipment, structure of the lifting and loading and unloading as well as the need of transport lifting tasks.
