For example, the dangerous operations involved include working at heights, working at high temperatures, working near molten metal liquids, etc.; there are many tools and spare parts involved, including air ducts, various basic tools for fitters, ladders, aluminum tapping port seals, etc., which will cause many problems such as high labor intensity, difficulty in operation, poor site cleanliness, and time-consuming and laborious transportation of items by operators. The surface temperature of the lifting bag is as high as 200°C or above. There is a risk of scalding when working close to it, and there is no better way to place the other tools neatly. It is often necessary for operators to carry them back and forth and arrange them, which takes a lot of time. For example, it is extremely time-consuming and labor-intensive to roll up the air pipe from the electrolytic cell. Although the ladder is currently set on the lifting bag to reduce the handling of the ladder, the top of the lifting bag is about 2 meters from the ground. The ladder lifting bag is usually set with fewer pedals, and the heat of the lifting bag is easily transferred to the ladder, making it inconvenient for people to go up and down and difficult to stand steadily.
