The invention particularly relates to a lifting appliance for lifting a reactor core guide post. The lifting appliance comprises a grabbing mechanism, a safety pin locking mechanism and a personnel operating mechanism, the safety pinning mechanism is sleeved with the grabbing mechanism, slides up and down in the grabbing mechanism under cooperation of a crane and extends out of the grabbing mechanism. The grabbing mechanism is sleeved with the personnel operation mechanism and moves up and down in the personnel operation mechanism under the cooperation of a crane. The safety pinning mechanism is movably connected with a clamping pin of the personnel operating mechanism, and the personnel operating mechanism limits rotary opening of the grabbing mechanism. Under the cooperation of the personnel operation mechanism and the crane, locking and unlocking of the safety locking mechanism and the personnel operation mechanism and locking and unlocking of the grabbing mechanism and the personnel operation mechanism are achieved. According to the lifting appliance for lifting the reactor core guide post, the guide post can be automatically or remotely and manually grabbed and released, and the safety and the reliability of operation are improved.
