The elevator includes an elevator car having a front portion which defines an entranceway. A car support frame is adjacent to the front portion, and a door supported by the car support frame is mounted for movement to open and close the entranceway. The car frame includes an upper beam, and a transom is mounted below the upper beam. A door actuator depends from the upper beam, within an enclosure cooperatively defined by the upper beam and transom. The door actuator will accommodate a vertical tunnel surrounding a hydraulic jack which extends upwardly through the elevator car, through the upper beam. The door actuator includes portions on opposite sides of the tunnel, and a third portion which interconnects these portions.
