Abstract
An elevator in which a driving apparatus, a traction sheave, and a counterweight-side rope hitching portion are arranged above one rail of the right and left cage-side guide rails, while a cage-side rope hitching portion and a speed governor are arranged above the other rail of the right and left cage-side guide rails. Since a control panel is arranged along a rear inner wall surface of the machine room, a large operation space can be secured in a center part of the floor of the machine room. Further, since a machine beam can be extended at full length in the back and forth direction in the machine room, no additional building-side receiving beam is needed.
