To provide a lifting device for a working machine capable of improving workability of lifting work for lifting a member included in the working machine, a lifting device group for the working machine, a lifting method of a lifted body, and an assembling method of a derricking body.SOLUTION: A lifting device 1 includes a base part 10, four holding parts 20, and four holding part moving parts 30. The base part 10 is held by a lifting wire 1B in a horizontal posture below a wire lifting part 1A. The four holding parts 20 each hold a lifted body. The holding part moving parts 30 can move at least two holding parts 20 among the four holding parts 20 relative to the base part 10. The holding parts 20 can be set at appropriate positions according to the dimension of the lifted body.SELECTED DRAWING: Figure 2

    【課題】作業機械を構成する部材を吊り上げる吊り上げ作業の作業性を向上することが可能な作業機械用吊り装置、作業機械用吊り装置群、被吊り上げ体の吊り上げ方法および起伏体の組立方法を提供する。【解決手段】吊り装置1は、ベース部10と、4つの把持部20と、4つの把持部移動部30と、を備える。ベース部10は、吊りワイヤ1Bによってワイヤ吊り部1Aの下方で水平な姿勢に保持される。4つの把持部20は、被吊り上げ体をそれぞれ把持する。把持部移動部30は、4つの把持部20のうちの少なくとも2つの把持部20をベース部10に対して相対移動させることが可能とされている。被吊り上げ体の寸法に応じて把持部20を適切な位置に設定することができる。【選択図】図2
