To exhibit high operability in replacement work or the like of a pressure governor stored in a narrow space inside a small-sized building without removing the small-sized building.SOLUTION: A crane main body F includes a hoisting mechanism W that is configured to be freely movable while a top surface of the crane main body F is positioned below a top surface of a main rail L1 in a side view and has a hoisting line W2 and an engaging part h freely engaging with a pressure governor G on a tip of the hoisting line W2. The crane main body further includes an aperture part Fa such that an extension portion Ga extended upward along a displacement direction of the pressure governor G can be arranged to protrude from the lower side to the upper side while maintaining the lifting attitude in which the engaging part h is engaged with the pressure governor G to lift the pressure governor G.SELECTED DRAWING: Figure 1

    【課題】小型建屋内の狭小空間に収められる整圧器の交換作業等を、小型建屋を取り外すことなく、高い操作性を発揮する。【解決手段】クレーン本体Fは、側面視において、クレーン本体Fの上面が主レールL1の上面より下方に位置した状態で移動自在に構成されると共に、巻上ラインW2と当該巻上ラインW2の先端に整圧器Gに係合自在な係合部hとを有する巻上機構Wを備え、且つ係合部hが整圧器Gに係合して整圧器Gを吊り上げた吊上姿勢において、整圧器Gの変位方向に沿って上方へ延出された延出部位Gaを、下方から上方へ突出して配設可能な開孔部Faを備える。【選択図】図1
