[0002] Elevators are a commonly used material handling equipment, mainly used for material transportation in vertical or inclined directions. They are widely used in many industries such as mining, construction, manufacturing, logistics and warehousing. Elevators can lift various forms of materials such as bulk materials, blocks, and finished products, which is of great significance for improving production efficiency, reducing labor intensity and optimizing material flow.
[0003] During the material transportation and lifting process of traditional elevators, if the materials are not adequately fixed, the shaking or displacement of the materials may directly cause them to fall from the elevator. Once the materials fall, it will not only cause direct economic losses, such as damage or scrap of the materials themselves, but may also cause damage to the personnel, equipment or ground below, and even cause serious safety accidents, such as personal injuries or major damage to equipment.
