The invention relates to an ultra-long reinforcement cage bending-deformation-resistant lifting appliance which comprises a supporting arm, a first telescopic arm and a second telescopic arm are arranged in the supporting arm in a sliding mode, the first telescopic arm is connected with the supporting arm through a thread transmission assembly, and the second telescopic arm is connected with the supporting arm through a thread transmission assembly. The first telescopic arm and the second telescopic arm are connected through a line transmission assembly, protrusions penetrating through the supporting arm are fixedly installed on the first telescopic arm and the second telescopic arm, a plurality of first hooks are arranged on the protrusions at equal intervals, an inclined tip is arranged at one end of each protrusion, and a plurality of second hooks are arranged at the other end of each protrusion. The inclined tip is matched with an elastic assembly arranged on the supporting arm, a second hook is installed on the elastic assembly, paying-off assemblies are arranged between the first telescopic arm and the supporting arm and between the second telescopic arm and the supporting arm, and the paying-off assemblies are rotationally connected with a main hanging head so that when a reinforcement cage is hoisted, the main hanging head can be hung on the main hanging head. And the phenomenon of bending deformation is avoided.
