Method for producing an elongated piece with thread, which is intended to take up a lift car through operation of a rotational, motor-driven drive shaft in the lift car, which by machine threads or similar engages with the elongated piece. At least two rod sections (2, 4) are used output components for the elongated piece, each rod section being equipped with detachable connectors (6, 10) at each end for interwork. The materials are detachably connected with the help of said connectors and the rod component that is made up of at least two interjoined rod sections is given the intended screw threads.<IMAGE> |
