Abstract
An elevator system is provided that includes a car guiderail, a first counterweight guiderail, a second counterweight guiderail, an elevator machine, a first guiderail mount and a second guiderail mount. The elevator machine includes a frame, a motor, a brake and a sheave. The first guiderail mount structurally connects the frame to the first and the second counterweight guiderails. The second guiderail mount structurally connects the frame to the car guiderail independent of the first guiderail mount.
Claims22
An elevator system, comprising:
- a car guiderail, a first counterweight guiderail and a second counterweight guiderail spaced from the first counterweight guiderail in a lateral direction, the car guiderail located between the first counterweight guiderail and the second counterweight guiderail in the lateral direction;
- an elevator machine including a frame, a motor, a brake and a sheave;
- a first guiderail mount structurally connecting the frame to the first and the second counterweight guiderails, the first guiderail mount structurally connected to the frame at a connection point located laterally between the motor and the brake;
- and
- a second guiderail mount structurally connecting the frame to the car guiderail independent of the first guiderail mount.
