A carriage which is drawn over a plurality of locations along a tightly threaded motor driven drive rod by a nut on the carriage, draws a chandelier support cable axially along the rod by way of a pulley on the carriage. The cable is wrapped on the pulley so that the vertical distance moved by the end of the cable for attachment to a chandelier is greater than the axial distance moved by the cable over the pulley. The drive rod is supported at each of the plurality of locations along the drive rod, against bowing.
