 図2は図1の第1ガイドレール最下段部21を昇降路1に設置する様子を示す図である。第1ガイドレール最下段部21の長手方向の寸法は、ピット11の底面から、作業者5がピット11の中で作業可能な高さであるピット内作業可能高さまでの間の寸法L2よりも短くなっている。したがって、昇降路1に設置された第1ガイドレール最下段部21の上端部は、ピット11の底面からピット内作業可能高さまでの間に配置される。ピット内作業可能高さとは、作業者5が可搬式の簡易的な足場台6に乗った状態で作業可能な高さである。この例では、ピット11の底面からピット内作業可能高さまでの寸法L2は、2500mmとなっている。 FIG. 2 is a diagram showing a state where the first guide rail lowermost step portion 21 of FIG. 1 is installed in the hoistway 1. The dimension in the longitudinal direction of the first guide rail lowermost step portion 21 is larger than the dimension L2 from the bottom surface of the pit 11 to the workable height in the pit that is the height at which the operator 5 can work in the pit 11. It is getting shorter. Therefore, the upper end portion of the first guide rail lowermost step portion 21 installed in the hoistway 1 is disposed between the bottom surface of the pit 11 and the workable height in the pit. The workable height in the pit is a height at which the worker 5 can work in a state where the worker 5 is on the portable and simple scaffolding platform 6. In this example, the dimension L2 from the bottom surface of the pit 11 to the workable height in the pit is 2500 mm.
 第2ガイドレール最下段部31の長手方向の寸法は、ピット11の底面からピット内作業可能高さまでの寸法L2よりも長くなっている。したがって、第2ガイドレール最下段部31の上端部は、ピット内作業可能高さよりも上方に配置されている。これにより、ピット内作業可能高さの範囲内で巻上機4を第2ガイドレール最下段部31に取り付けることができる。 The dimension in the longitudinal direction of the second guide rail lowermost step portion 31 is longer than the dimension L2 from the bottom surface of the pit 11 to the workable height in the pit. Therefore, the upper end part of the 2nd guide rail lowermost step part 31 is arrange | positioned above the workable height in a pit. Thereby, the hoisting machine 4 can be attached to the 2nd guide rail lowest step part 31 within the range of workable height in a pit.
 図3は図1の第1ガイドレール二段目部22を昇降路1に設置する様子を示す図である。第1ガイドレール二段目部22の長手方向の寸法は、第1ガイドレール最下段部21の長手方向の寸法と第1ガイドレール二段目部22の長手方向の寸法とを加算した寸法が、ピット11の底面から、既設エレベータの既設かご7を最下階に配置した状態で作業者5が既設かご7の上部で作業可能な高さである最下階かご上作業可能高さまでの間の寸法L3よりも長くなるようになっている。したがって、第1ガイドレール二段目部22が第1ガイドレール最下段部21の上端部に配置された場合に、第1ガイドレール二段目部22の上端部は、最下階かご上作業可能高さ以上に配置される。この例では、ピット11の底面から最下階かご上作業可能高さまでの間の寸法L3は、ピット11の深さ寸法L1と、2500mmとを加算した値となっている。 FIG. 3 is a view showing a state where the first guide rail second-stage portion 22 of FIG. 1 is installed in the hoistway 1. The length in the longitudinal direction of the first guide rail second stage portion 22 is the sum of the length in the longitudinal direction of the first guide rail lowermost step portion 21 and the length in the longitudinal direction of the first guide rail second step portion 22. From the bottom surface of the pit 11 to the height at which the worker 5 can work on the upper floor of the existing car 7 while the existing car 7 of the existing elevator is arranged on the lower floor. It is longer than the dimension L3. Therefore, when the first guide rail second-stage portion 22 is arranged at the upper end of the first guide rail lower-stage portion 21, the upper end portion of the first guide rail second-stage portion 22 is the upper floor car work. Arranged more than possible. In this example, the dimension L3 between the bottom surface of the pit 11 and the workable height on the lowest floor car is a value obtained by adding the depth dimension L1 of the pit 11 and 2500 mm.
 また、第2ガイドレール最下段部31の長手方向の寸法は、ピット11の底面から最下階かご上作業可能高さまでの間の寸法L3よりも短くなっている。 Further, the longitudinal dimension of the second guide rail lowermost step portion 31 is shorter than the dimension L3 from the bottom surface of the pit 11 to the workable height on the lowermost floor car.
 第2ガイドレール二段目部32の長手方向の寸法は、第2ガイドレール最下段部31の長手方向の寸法と第2ガイドレール二段目部32の長手方向の寸法とを加算した寸法が、ピット11の底面から最下階かご上作業可能高さまでの間の寸法L3よりも長くなるようになっている。したがって、第2ガイドレール二段目部32が第2ガイドレール最下段部31の上端部に配置された場合に、第2ガイドレール二段目部32の上端部は、最下階かご上作業可能高さ以上に配置される。また、第2ガイドレール最下段部31の長手方向の寸法と第2ガイドレール二段目部32の長手方向の寸法とを加算した寸法は、第1ガイドレール最下段部21の長手方向の寸法と第1ガイドレール二段目部22の長手方向の寸法とを加算した寸法と同一となっている。したがって、第1ガイドレール二段目部22の上端部の高さは、第2ガイドレール二段目部32の上端部の高さと一致している。第1ガイドレール三段目部24の長手方向の寸法と、第2ガイドレール三段目部34の長手方向の寸法は同一となっている。 The dimension in the longitudinal direction of the second guide rail second stage part 32 is the dimension obtained by adding the dimension in the longitudinal direction of the second guide rail lowermost part 31 and the dimension in the longitudinal direction of the second guide rail second stage part 32. The length from the bottom surface of the pit 11 to the workable height on the lowest floor car is longer than the dimension L3. Therefore, when the second guide rail second step 32 is disposed at the upper end of the second guide rail lowermost step 31, the upper end of the second guide rail second step 32 is the upper floor car work. Arranged more than possible. The dimension obtained by adding the longitudinal dimension of the second guide rail lowermost step part 31 and the longitudinal dimension of the second guide rail second stage part 32 is the dimension of the first guide rail lowermost step part 21 in the longitudinal direction. And the dimension of the first guide rail second-stage portion 22 in the longitudinal direction are the same as the added dimension. Therefore, the height of the upper end portion of the first guide rail second-stage portion 22 matches the height of the upper end portion of the second guide rail second-stage portion 32. The longitudinal dimension of the first guide rail third stage portion 24 and the longitudinal dimension of the second guide rail third stage portion 34 are the same.
