To provide a slinging hanger as one of measures for reduction of a burden on a worker during slinging work of a long steel member and shortage of labor and since the conventional slinging hanger hook used in the slinging work is made of steel and heavy, repetitive slinging/unslinging work is exhausting work so that a work method, which can reduce the slinging/unslinging work and is easily performed even by one person because of the shortage of labor although two persons have been required for the conventional slinging work.SOLUTION: A worker can put/remove hanging hooks on/from longitudinal opposite side end parts of a suspended load by using a balance frame at a front work position without requiring the worker to directly hold the hanging hooks. This makes it possible to facilitate the work only by one person.SELECTED DRAWING: Figure 2
【課題】長尺鋼材の玉掛け作業時の作業者への負担軽減、人手不足対策の一つとして考案した。従来の玉掛け作業での玉掛け吊り具フックは鋼鉄製で重く反復しての玉掛け、玉外しの作業は重労働である。その作業の軽減化を計る、また従来の玉掛け作業は2名であったが昨今、人手不足もあり1名でも容易な作業方法が求められる。【解決手段】本発明は作業者が吊りフックを直接持つ事無く吊り荷長手方向対面側端部に手前作業位置で天秤フレームを利用して吊りフックの掛け外しを可能とし、1名での作業を容易にする。【選択図】図2
