A gantry conveyor apparatus for transporting components between work stations in an assembly line. The apparatus includes an elevated gantry beam and two gantry carts movably mounted to roll along the beam. The gantry conveyor apparatus also includes a conveyor coupled to each gantry cart. The conveyor moves the carts along the gantry beam between stations in an assembly line. A lift tube is supported on each gantry cart and engages a part at one station, raises the part to an elevated transport position, and lowers and releases the part at a subsequent station. The apparatus also includes a harmonic lift drive coupled to the lift tubes and drives the lift tubes using a single motor rather than a separate motor at each lift.
