To make it possible to easily perform the positioning of a trolley beam at a horizontal fixing position even if a heavy object such as a hoisting machine and a control panel for an elevator and the like is lifted via a high working place such as a stairway while preventing the work time required for the entire lifting work of the heavy object from being drastically increased.SOLUTION: A portal type auxiliary fixture for stairway lifting includes an upper side portal type structure and a lower side portal type structure installed on a stairway and a trolley beam for connecting the upper side portal type structure and the lower side portal type structure. A guide mechanism for guiding the trolley beam is provided for at least one of the upper side portal type structure and the lower side portal type structure.SELECTED DRAWING: Figure 2

    【課題】エレベーター等の巻上機や制御盤などの重量物を階段などの作業場所が高いところ経由して揚重するものであっても、簡便にトロリービームの水平固定位置の位置決めが可能で、重量物の揚重作業全体の作業時間が大幅に掛かることがないこと。【解決手段】階段上に設置された上部側門型構造体及び下部側門型構造体と、前記上部側門型構造体と前記下部側門型構造体を連結するトロリービームと、を備えた階段揚重用門型雇であって、前記上部側門型構造体と前記下部側門型構造体の少なくとも一方に、前記トロリービームをガイドするガイド機構を備えていることを特徴とする。【選択図】図2
