Most cranes operate by first positioning the spreader horizontally or vertically to lift materials. Once the material is secured, the crane moves it to the designated location. After unloading, the crane returns to the reclaiming point to begin another cycle. This process of lifting, transporting, and unloading typically occurs in a sequential manner, with each part of the system operating intermittently during the work cycle. Hoisting machinery is primarily designed for moving individual items, but it can also handle bulk materials like coal, ore, and grain when equipped with specialized grabs. For liquids such as molten steel, containers are used instead. In addition, certain lifting devices, like elevators, are specifically built to transport people. In some industries, lifting equipment serves as the primary operational machine, such as port cranes that are essential for loading and unloading cargo at docks and railway stations.

These machines are often operated by trained personnel and require regular maintenance to ensure safe and efficient performance. They play a critical role in logistics, construction, and manufacturing, where precise and reliable movement of heavy objects is necessary. The versatility of hoisting equipment makes it an indispensable tool in modern industrial environments.
