Problems solved by technology
[0002] In the busy farming season, many rural families choose to dry their grains on their roofs or balconies. However, because the grains are heavy, it is a waste of resources to transport them by machine. Therefore, many families choose to transport the grains to their balconies or balconies manually. On the roof, but the manual work is heavy and there is a certain risk factor, so it is necessary to design a simple household hand-operated crane to solve the above problems
