The invention relates to the technical field of electric reactors, in particular to a lifting tool special for a large electric reactor. The lifting tool comprises cross beams and a chassis; the chassis is welded at the bottoms of the cross beams; reinforcing beams are welded between the two sides of the cross beams and the chassis; lifting lugs are fixed to the two sides of the upper parts of the cross beams separately; and a plurality of lifting rings are fixed at the bottom of the chassis. The lifting tool has teh advantages that one chassis is arranged, the multiple lifting rings are arranged on the chassis and can be connected to a plurality of lifting plates on the upper part of the electric reactor through ropes, the lifting lugs on the two ends of each cross beam can be connected to two crown blocks through ropes, and therefore on the other hand, the transportation stability of the electric reactor can be improved, and on the other hand, one cross beam is subjected to combined lifting by the two crown blocks so that a heavier electric reactor can be lifted.
