The door is in a closed position received by the door frame, when the boom is rotated toward the door frame and the Door is rotated to an infacing position relative to the door frame. The door is in an open position withdrawn from the door frame, when the boom is rotated away from the door frame. The truck is disabled from reciprocating along the boom and the door is disabled from rotating, when the door is in the closed position. The truck is enabled for reciprocating along the boom and the door is enabled for rotating, when the door is in the open position.
