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. An aspect of the invention is to allow the descent of the elevator to drive the electric motor arranged to act as a generator and provide regenerative braking as well as power to drive an alarm device or devices.
