The invention belongs to the technical field of crane lifting, is to overcome the problems of displacement of superlift counterweights of large-scale crawler cranes, namely long work periods, high costs and low efficiencies, and provides a tool used for assisting movement of a crane superlift counterweight. The tool comprises a supporting rod. Two ends of the supporting rod are respectively provided with a lifting lug. Lifting shafts are installed in the lifting lugs. Two ends of each lifting shaft are respectively provided with a baffle plate. Each lifting shaft is provided with two connecting sheets which are at two sides of the corresponding lifting lug. A pin roll is mounted at the lower ends of each corresponding two connecting sheets and is used for connecting a lifting bar of the superlift counterweight. The tool shortens the work period of displacement of superlift counterweights of large-scale crawler cranes, increases the working efficiency and reducing the working cost.
