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.

Elevator with an operation space in a center of a machine room

In an elevator, a drive device, a traction sheave, and a weight-side stop portion are arranged above one of a pair of left and right cage-side guide rails, and a cage-side stop portion and speed governor are arranged above the other cage-side guide rail. A wide workspace is realized in the middle of the floor of the machinery chamber, since the control panel is arranged along the middle of the inside wall surface of the front face of the machinery chamber. Furthermore, provision of an additional supporting beam mounted in the building is unnecessary, since the machine beam can extend fully in the forwards/rearwards direction in the interior of the machinery chamber.

Elevator

Rubber vibration isolators are held between a base frame supporting a driving device and an upper deflecting sheave, and a support connected to car guide rails and a counterweight guide rail. The rubber vibration isolators are held between a horizontal member and vertical members of a support frame supporting lower deflecting sheaves. Transmission of vibrations generated by the driving device, the upper deflecting sheave, and the lower deflecting sheaves to the side walls of an elevator shaft can be intercepted.
