PROBLEM TO BE SOLVED: To provide a repair method for an existing elevator device which can be applied to repair of a hydraulic elevator device for a heavy load, and which can perform repair work by installing a relatively fewer number of apparatus, and an elevator device.SOLUTION: In a repair method for an existing elevator: for example, both a hydraulic cylinder 5 and a plunger 6 are removed from a hoistway 1; a ball screw 10 for elevating/lowering a car 2, and a hollow shaft motor 11 having a nut part 11a screwed to the ball screw 10 and capable of rotationally driving the nut part 11a are arranged in the hoistway 1; and repair work is performed so that the car 2 can be elevated/lowered via the drive of the nut part 11a and the ball screw 10 according to an operation of the hollow shaft motor 11.
【課題】重量物用油圧式エレベータ装置の改修にも適用させることができ、また、比較的少ない機器の設置で改修作業を行うことができる既設エレベータ装置の改修方法及びエレベータ装置の提供。【解決手段】本発明に係る既設エレベータの改修方法は、例えば油圧シリンダ5とプランジャ6の両方を昇降路1から撤去し、乗かご2を昇降させるボールねじ6と、このボールねじ6に螺合するナット部11aとを有しこのナット部11aを回転駆動可能な中空軸モータ11とを昇降路1に配置し、中空軸モータ11の作動に伴うナット部11a及びボールねじ10の駆動を介して乗かご2が昇降可能となるように改修作業を行うようにした。【選択図】図1
