[0002] In the steel pipe production process, bridge cranes are typically used to lift and move steel billets for loading, transportation, or further processing. Currently, there are many types of bridge cranes on the market. For example, Chinese Patent CN120270889A discloses a bridge crane for transferring steel plates from offshore wind turbine monopile production, and Chinese Patent CN221917110U discloses a bridge beam lifting and transfer device. In the crane of Chinese Patent CN120270889A, the suction cup lifting device is directly connected to the lifting trolley via two steel wire ropes, which is prone to swaying during lifting. The bridge beam lifting and transfer device disclosed in Chinese Patent CN221917110U avoids swaying by using multi-section telescopic rods; however, its lifting device makes it inconvenient to adjust the angle of the lifted load.
