An elevator system including an elevator car having an entranceway, a door having one or more door panels mounted for movement to open and close the entranceway, a door operator for the door, and mounting hardware for mounting the door operator on top of the elevator car. The mounting hardware provides horizontal and vertical adjustment of the door operator, with all adjustments being easily made from the top of the car. When the elevator car has a two-speed door, the high and low speed hanger tracks are horizontally spaced from one another, and they are mounted outside of the vertical projection of the door operator frame. The door hanger plates for both the high and low speed door panels are disposed between the hanger roller tracks. The spacing between the high and low speed roller tracks enables the hanger plates and door panels to be placed in position, or to be removed, from the top of the car.
