[0003] The refractory materials used in the production process of steel enterprises are not only large in quantity, but also have a wide variety of packaging specifications. Each type of steelmaking refractory material has different shapes and sizes, but the overhead crane only has two types of lifting tools, hooks and wire ropes, which cannot meet the lifting needs. Therefore, there is no suitable lifting device when lifting many types of refractory materials. During the lifting process, the refractory materials may move horizontally or even fall off from the lifting device, posing a serious safety hazard.
