Under a condition that a weight does not slant in the vertical direction, the weight which cannot be directly lifted through the position over the barycenter of the weight can be lifted in a simple manner with low cost. The invention provides a lifting fixture (1) used for lifting a winch (2) by the use of a chain pulley (5). The lifting fixture (1) comprises a lower end part (1a) provided with a through hole (1d) used for being connected to a lifting point (2b) of the winch (2) through a first eye bolt (3); an upper end part (1b) provided with a threaded hole (1e) which is located on a virtual perpendicular line (12) passing through the barycenter (6) of the winch (2) during the installation process of the winch (2) and is connected to a second eye bolt (4) lifted by the chain pulley (5); and a connecting part (1c) connecting and integrating the lower end part (1a) and the upper end part (1b).
