The invention provides a novel electric shackle hook group for a crane. The novel electric shackle hook group is characterized in that an upper bearing frame is articulated with a pulley through a pulley shaft, an upper substrate is fixed below the upper bearing frame, and fastened with an annular outer raceway below through a bolt I, a groove is formed in the inner circumferential surface of the outer raceway, a lower substrate is fixed above a lower bearing frame, and fastened with a toothed ring provided with inner teeth above through a bolt II, a groove is formed in the outer circumferential surface of the toothed ring, a slewing bearing is arranged between the grooves of the outer raceway and the toothed ring, the lower bearing frame is articulated with a hook through an articulated shaft, a motor and a speed reducer are fixed and connected to the upper substrate, and a gear is fixed at the lower end of an output shaft of the speed reducer, and meshed with the inner teeth of the toothed ring. The electric shackle hook group with a new structure adopting the technical scheme is simple and reasonable in overall structure, and not high in requirement for production process, so that the production cost is reduced, and the production cycle is shortened. The novel electric shackle hook group is safe and reliable, long in service life, and very convenient for on-site operation and maintenance by workers.
