Abstract:
A lift system configured to lift an article, the lift system includes a drum that rotates about an axis, a first cable that winds around the drum when the drum rotates about the axis in a first direction to raise the article and the first cable unwinds from the drum when the drum rotates about the axis in a second direction to lower the article. The lift system further includes a motor operable to rotate the drum about the axis in the first direction, an electrical cable configured to supply power from a power source to the article, and a second cable that is coupled to the electrical cable and the second cable pulls at least a portion of the electrical cable from a substantially vertical position to a substantially horizontal position.
