PURPOSE: A jig for lifting stud bolts is provided to fix stud bolts, which many parts accomplish one group, in a state where the stud bolts are moved to the upper part of a cylinder frame, thereby rapidly fixing. CONSTITUTION: A jig for lifting stud bolts comprises a frame(110), a spring balance(120), and a buffering member(130). The frame is connected with a rope drawn out from an overhead traveling crane. The spring balance is installed in the frame and the wire is drawn out from the spring balance. The wire is connected with stud bolts which many parts accomplish one group and is elastically wound. The wire drawn out from the spring balance penetrates the frame. The buffering member is arranged in the outer diameter of the penetrated wire. |
