摘要： PURPOSE:To center and hold a jamb in simple constitution easily by installing a slide member which is freely movable to the landing side and the elevation way side on a support member installed on a threshold, and supporting leg parts of the jamb between the slide member and the support member. CONSTITUTION:In centering a jamb 9 provided at an elevator aperture, a protruding part of a support member 5 is first inserted into a threshold groove 4A of a threshold 4 placed along a partition wall 3 close to a landing 2 on the side of an elevator shaft 1. Next, a lateral position of the support member 5 is regulated to a reference piano line set for centering devices in the elevator shaft 1, and after regulation, it is fixed by bolts. A slide member 7 freely slidably supported on the support member 5 is then moved to the landing 2 side, and the jamb 9 is held between the slide member 7 and a stop part 5D of the support member 5 as gap between them is enlarged. Both leg parts of the jamb 9 are thus centered to specified positions, and the jamb 9 is fixed to the building side by welding in this condition.

摘要： PURPOSE:To perform the centering operation of a balancing weight guide rail automatically. CONSTITUTION:A first roller 34 and a second roller 35 coming into contact with both sides of a guide part 24c is held on a first support bracket 31 being installed in the outer side of a floor plate 21, and a third roller 38 coming into contact with an end face of this guide part 24c is held on a second support bracket 36 orthogonal with the first support bracket 31. Then, those of rollers 34, 35, 38 are engaged with the guide part 24c at lowermost part of an elevator shaft, and the floor plate 21 is driven up and down, thereby regulating three-way positions of the balancing weight guide rail 24a. Thus, a span of centering operation time is reducible and, what is more, highly accurate centering is made performable.
