[0002] In industrial production, lifting and rotating workpieces is a common requirement. However, traditional lifting equipment can only achieve simple lifting or rotation functions, which is not flexible and complicated to operate. In particular, in some scenarios that require precise rotation and positioning, and the ability to hang workpieces multiple times, existing technologies are still unable to meet these requirements. Therefore, a lifting and rotating device that can simultaneously achieve precise rotation and positioning of the workpiece and change the rotation center is developed.
