PROBLEM TO BE SOLVED: To safely mount a lifting machine such as an electric-driven chain block by installing a heavy cargo lifting auxiliary fixture, and to reduce the physical burden on a worker engaged in installation work. SOLUTION: The heavy cargo lifting auxiliary fixture comprises a pair of stays 5 which are held at their lower end parts on a floor surface in the vicinity of an opening part 15 and erected to the opening part 15 side, a beam part 6 to connect upper end parts of the stays 5, an upright column 11 erected on the floor surface 16, a hoist 12a mounted on an upper end part of this upright column 11, and a wire 12b for erection which is connected to the beam part 6 and wound by the hoist 12a. In installing the heavy cargo lifting auxiliary fixture, a lift 8 such as an electric-driven chain block is mounted on the beam part 6 while the stays 5 are supported by a supporting means 10 to keep the beam part 6 to be lifted from the floor surface 16, the wire 12b for erection drawn from the hoist 12a is connected to the beam part 6, and then, the hoist 12a is driven to erect the stays 5 to the opening part 15 side along a perpendicular surface.
