The invention discloses a lifting electromagnet lug height adjustment device, comprising a bolt, a pin shaft, a locknut and an adjusting screw barrel. A pin shaft hole in the lug is a longitudinal long hole, the pin shaft passes through the long hole, two ends of the pin shaft are provided with through holes, an adjusting bolt penetrates into the through hole, the locknut and the adjusting screw barrel are screwed under the adjusting bolt, and the adjusting screw barrel is fixed on a electromagnet yoke plate. When the device is in use, the height of the pin shaft is changed by rotation of the adjusting bolt, and meanwhile, height from the pole bottom face of the electromagnet to a crane hook can be adjusted. Therefore, the pole bottom face of each combined electromagnet is on the same plane. Contact area between the electromagnet and a steel plate is guaranteed, and the electromagnet can give full play to rated attraction force.
