TOWER ELEVATOR ALARM SYSTEM |
摘要 |
An elevator within a tower, such as a wind tower, includes a traction or drum type hoist powered by an electric motor where the hoist provides the mechanism to cause the vertical ascent or descent of the elevator. The descent of the elevator is used to drive the electric motor, which is arranged to act as a generator and provide regenerative braking as well as power to drive an alarm device or devices. |
