METHOD OF CONSTRUCTING STRUCTURE UNDER VIADUCT AND LIFTING DEVICE
To obtain a method of constructing a structure easily even under a viaduct and a lifting device used for the method.SOLUTION: An H-steel 30 is placed on a front end of a fork sheath 20 by an operator and pushed it rearward. The H-steel 30 is slid upward along an inclined surface 23a and then fallen between a front holding surface 23b and a back holding plate 24a to be stored therebetween. Providing the inclined surface 23a makes the operator easily store the H-steel 30 between the front holding surface 23b and the back holding plate 24a only by pushing the H-steel 30 from the front side to the back side. Next, an operator at a riding part 11 turns on a radio switch of an electromagnet 25. Accordingly, the electromagnet 25 is magnetized and the H-steel 30 is magnetically attached to the back holding plate 24a by the magnetic force (holding force) so as to be fixed to the fork sheath 20.SELECTED DRAWING: Figure 1
【課題】高架下であっても容易に構造物を構築する方法及びこれに用いられる揚重装置を得る。【解決手段】作業員が、Ｈ鋼３０をサヤフォーク２０の先方端上に載せ、後方に向けて押す。そうすると、Ｈ鋼３０は、斜面２３ａを滑り上がった後、前方押さえ面２３ｂと後方押さえ板２４ａとの間に落ちて、収められる。斜面２３ａを設けることにより、作業員は、Ｈ鋼３０を前方から後方に押すのみで、前方押さえ面２３ｂと後方押さえ板２４ａとの間にＨ鋼３０を容易に収納することができる。次に、搭乗部１１に居る作業員が、電磁石２５の無線スイッチをオンにする。そうすると、電磁石２５が磁力を帯び、この磁力（保持力）によってＨ鋼３０が後方押さえ板２４ａに磁着され、サヤフォーク２０に固定される。【選択図】図１
