To provide an elevator rope exchange method capable of exchanging each of existing ropes into new ropes separately.SOLUTION: There is provided an elevator rope exchange method comprising an upper rope floating step for pushing up an upper rope part 31 wound on an upper part of a sheave 61 to reduce friction force generated between the upper part of the sheave 61 and the upper rope part 31, a lower rope floating step for pushing down a lower rope part 32 wound over a lower part of the sheave 61 and a lower part of a deflector wheel 7 to reduce friction force generated between the lower part of the sheave 61 and the lower part of the deflector wheel 7, and the lower rope part 32, a rope connection step for connecting an existing rope 3A and a new rope 3B, and a rope exchange step for winding the existing rope 3A and sending the new rope 3B after the upper rope floating step, the lower rope floating step, and the rope connection step.SELECTED DRAWING: Figure 9

    【課題】複数の既設ロープのそれぞれを別々に新設ロープに交換することができるエレベータロープ交換方法を得る。【解決手段】綱車61の上部に巻き掛けられた上部ロープ部31を押し上げて、綱車61の上部と上部ロープ部31との間に発生する摩擦力を低減させる上部ロープ浮かせ工程と、綱車61の下部およびそらせ車7の下部に渡って巻き掛けられた下部ロープ部32を押し下げて、綱車61の下部およびそらせ車7の下部と下部ロープ部32との間に発生する摩擦力を低減させる下部ロープ浮かせ工程と、既設ロープ3Aと新設ロープ3Bとを接続するロープ接続工程と、上部ロープ浮かせ工程、下部ロープ浮かせ工程およびロープ接続工程の後、既設ロープ3Aを巻き取るとともに新設ロープ3Bを送り出すロープ交換工程とを備えている。【選択図】図9
