PROBLEM TO BE SOLVED: To lift an elevator hoisting machine for a heavy object up to a lofty building top part by using a general-purpose lifting winch, in an elevator for a skyscraper.SOLUTION: In a method for lifting an elevator hoisting machine for a skyscraper, a lifting winch 12 is installed on the topmost floor landing 4; a deceleration roping is formed by winding between a fixed pulley 14 and a fall block 15 a deceleration rope 17 taken out from the lifting winch 12 and wound up; the fall block 15 and the elevator hoisting machine 23 are detachably connected to each other by suspension ropes 18 and 19; the elevator hoisting machine 23 is lifted to intermediate floors 2 and 3 by driving the lifting winch 12; the elevator hoisting machine 23 is temporarily held on the intermediate floors 2 and 3 by temporary holding ropes 20 and 21; the lowest part of the suspension rope 18 is detached in a temporarily held state, and an upper part of the suspension rope 19 is connected to the elevator hoisting machine 23 and again suspended; and the elevator hoisting machine 23 is lifted to a machine room 9 by driving the lifting winch 12 again.
【課題】超高層エレベーターで重量物のエレベーター巻上機を汎用の揚重ウィンチを使用して高高所の建物頂部へ揚重可能とすること。【解決手段】最上階乗場4に揚重ウィンチ12を設置し、揚重ウィンチ12から引き出され巻き取られる減速ロープ17を定滑車14と動滑車15との問で巻き回して減速ローピングを形成し、動滑車15とエレベーター巻上機23を分離可能な懸垂ロープ18,19で連結し、揚重ウィンチ12を駆動してエレベーター巻上機23を中間階2,3まで揚重し、中間階2,3で仮保持ロープ20,21によりエレベーター巻上機23を仮保持し、仮保持状態で最下部の懸垂ロープ18を取り外して上部の懸垂ロープ19をエレベーター巻上機23に連結して吊り戻し、再度揚重ウィンチ12を駆動してエレベーター巻上機23を機械室9まで揚重すること。【選択図】図2
