An elevator system includes a car (2) and a counterweight (4) configured to travel along guide rail units (6; 8) and a machine (12) being positioned above the car (2) and configured to drive a tension member (10). In addition, the machine (12) is mounted on an overhead structure (20) and the overhead structure (20) is supported only by the guide rail units (6; 8). This mounting arrangement avoids contact between the overhead structure and the elevator hoistway in the building, and isolates transfer of vibration and noise and improves the load bearing conditions of the walls of the building. |
