A car support frame is disposed immediately 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 member, and a transom is mounted below the upper beam member. A door operator for the door depends from the upper beam member, within an enclosure cooperatively defined by the upper beam member and transom. The door operator will accommodate a vertically disposed tunnel surrounding a hydraulic jack which extends upwardly through the elevator car, through the upper beam member, with the door operator including first and second portions disposed on opposite sides of the tunnel, and a third portion which interconnects the first and second portions.
