Abstract
A height adjustable suspension for supporting a fixture frame from an overhead location has a drive shaft rotatably supported in the frame and extending parallel to the length dimension of the frame, a motor supported in the frame and operatively connected with the shaft for rotating the same, a plurality of longitudinally spaced winding drums mounted on the shaft for rotation therewith and separate suspension cables associated with each winding drum. Each cable is mounted on the overhead location and has an end directly affixed to the respective drum. The course of each cable from the overhead location to the respective winding drum is, at all points of the cable, perpendicular to the length dimension of the frame.
