In the construction of extraterrestrial bases such as the Moon，cranes areessential engineering equipment.Because of the weak personnel support ability，the swing during the lifting operation should be suppressed as much as possible by the actuating ability of the equipment itself.Based on the basic mechanical principle that the mechanical energy of a dynamic system can be dissipated by negative work，an active suppression method is proposed to control the movement of the lifting point of the crane according to the hanging force.The stability of the closed-loop system is proven mathematically.An experimental scheme is designed to verify the swing reduction principle of the crane with a system composed of a planar two-degrees-of-freedom manipulator，a multi-axial force sensor，and a real-time simulation controller.The results show that under the active action of the lifting point，the swing can be rapidly stopped，and the attenuation time is reduced to 1.53% of the free vibration.
