To provide a lifting construction method of an escalator capable of easily performing a removal/new construction work of an escalator truss even if a structure capable of supporting a lifting device above the escalator truss cannot be secured.SOLUTION: In a lifting construction method of an escalator truss, an upper portal frame 32 is erected, a lower portal frame 34 is erected, and two connecting beams 36 are installed across the upper portal frame and the lower portal frame. Upper hanging beams 38a, 38b are fixed on upper end parts of the two connecting beams 36, and lower hanging beams 42a, 42b are fixed on lower end parts thereof. Upper lifting devices 39a, 39b are arranged on the upper hanging beams, and lower lifting devices 43a, 43b are arranged on the lower hanging beams. An upper end part ET3 of an escalator truss ET is hung down and supported by the upper lifting devices, and a lower end part ET4 of the escalator truss ET is hung down and supported by the lower lifting devices, and the escalator truss ET is hung up and down by the upper lifting devices and the lower lifting devices.SELECTED DRAWING: Figure 1

    【課題】上方に揚重装置を支持可能な構造物を確保できない場合でもエスカレータートラスの撤去新設作業を容易に行うことができるエスカレーターの揚重工法を提供する。【解決手段】エスカレータートラスの揚重工法は、上部門型架台32を立設し、下部門型架台34を立設し、上部門型架台と下部門型架台とに渡って2本の連結梁36を架設する。2本の連結梁36において、その上端部に上部吊りビーム38a,38bを固定し、その下端部に下部吊りビーム42a,42bを固定する。上部吊りビームに上部揚重装置39a,39bを配置し、下部吊りビームに下部揚重装置43a,43bを配置する。上部揚重装置によってエスカレータートラスETの上端部分ET3を吊り下げ支持し、下部揚重装置によってエスカレータートラスETの下端部分ET4を吊り下げ支持し、上部揚重装置及び下部揚重装置によってエスカレータートラスETを吊り揚げ及び吊り降ろす。【選択図】図1
