[0002] Lifting hooks are an essential part of mechanical lifting in industrial production, bridge construction, and transportation. Currently, cranes rely on hook assemblies and ropes to connect heavy objects. As the complexity of lifting materials in the lifting field continues to increase, the materials being lifted are no longer simply moved back and forth. They often need to be rotated a certain angle for installation or placement in special locations. An intelligent electric rotating hook assembly with application number CN2022230108284 has an unreasonable structural force design, a large frame size, and a heavy deadweight. Conventional motor reducers have poor load-bearing capacity and stability, and the drive and electrical control may be relatively simple, making such high-precision control impossible.
