To provide an indoor lifting device capable of ensuring sufficient lifting margin and improving the workability even in a room with a low ceiling.SOLUTION: The indoor lifting device 10 includes an upper frame body which is supported by a plurality of poles and has a rectangular frame shape and a first shaft and a second shaft which are stretched between two long sides forming the rectangular frame shape and extend in a short side direction. The indoor lifting device further includes a first wire pulley 80 which can rotate around the first shaft, a second wire pulley 82 which can rotate around the second shaft, a wire return pulley 84 rotatably supported by one of two short sides of the rectangular frame shape, and a wire fixing part 86 provided in the other part of the two short sides. In addition, the indoor lifting device includes a lifting part 40 for lifting an object equipment to be lifted, a wire 50 suspended on the lifting part 40, and a winch part 60 which has a drum feeding out or winding the wire 50 and is held by a pole at the lower side of the wire return pulley 84.SELECTED DRAWING: Figure 1
【課題】室内揚重装置において、天井が低い室内においても十分な吊上げ代を確保し、作業性を向上させることである。【解決手段】室内揚重装置10は、複数の支柱によって支持され矩形枠形状を有する上枠体と、矩形枠形状を構成する2本の長辺に渡され短辺方向に延びる第1軸と第2軸とを有する。また、第1軸周りに回転可能な第1ワイヤ掛車80と、第2軸周りに回転可能な第2ワイヤ掛車82と、矩形枠形状を構成する2つの短辺の一方に回転可能に支持されたワイヤ返し車84と、2つの短辺の他方に設けられるワイヤ固定部86とを有する。さらに、揚重対象機器を吊上げる吊上部40と、吊上部40に懸けられるワイヤ50と、ワイヤ50を繰り出し巻取るドラムを有し、ワイヤ返し車84の下方側で支柱に保持されたウインチ部60を備える。【選択図】図1
