The invention discloses a lifting tool for lifting large annular parts. The lifting tool for lifting the large annular parts comprises a lifting shoulder pole, wherein pin shaft mounting bases are symmetrically arranged at two ends of the lifting shoulder pole; at least two radial pin shaft holes are formed in each pin shaft mounting base; the pin shaft holes are formed in the same circumference; pin shafts are mounted in the pin shaft holes; sleeves are correspondingly arranged on the pin shaft mounting bases and arranged at one ends of the pin shafts in a sleeving manner; the sleeves are fixedly arranged on the pin shaft mounting bases; a telescoping mechanism is mounted between the sleeves and the pin shafts and used for controlling the pin shafts to extend and retract. The lifting tool for lifting the large annular parts and annular entities are rigidly fixed by virtue of the pin shafts to form an integral body; the danger caused by motion between the lifting tool and workpieces can be avoided during lift
